Introduction Overview The Model ML48 is a versatile and powerful helper for moving earth, gravel and debris on construction sites and elsewhere – see Fields of application, attachments on page 9.

Equip the machine with the respective safety devices when using it as a lifting accessory – see Applications with lifting gear on page 18.

The main components of the machine are:

• ROPS certified cab, enclosed version (standard).

• or ROPS tested cab, open version (option).

• Oil-cooled Deutz four-cylinder in-line diesel engine, 59 hp (44 kW) at 2400 rpm.

• Exhaust emissions according to EC directive 97/68/EC. • Sturdy steel frame; rubber-mounted engine.

• Automotive drive, infinitely variable hydrostatic axial-piston gearbox; maximum speed 12 mph (20 km/h) (25 mph [40 km/h] option).

• Hydraulic four-wheel power steering with emergency steering feature. The emergency steering feature, located inside the hydraulic system, allows you to steer the machine if you lose hydraulic or motor power.

• Front and rear planetary axles, rear axle with oscillation.

• Service brake (mechanical and hydrostatic), mechanical disc-type parking brake.

Hydrostatic drive

The diesel engine drives a hydraulic pump, whose oil flow is sent to a hydraulic motor flanged onto the rear axle. The force of the hydraulic motor is transmitted to the rear axle via the transfer gearbox. At the same time, the front axle is driven by the cardan shaft, ensuring full-time four-wheel drive.

Work hydraulics and hydrostatic fourwheel steering

The diesel engine also drives the joint gear pump for work hydraulics and hydrostatic fourwheel steering. The oil flow of this pump depends on the diesel engine speed only.

When the machine is in operation, the entire diesel engine output can be transmitted to the gear pump for work hydraulics and steering by using the inching valve. This valve responds as soon as the service brake is used, reducing or cutting off power input of the drive. Therefore, full engine output is available for the machine by pressing the accelerator pedal and the brake pedal at the same time.

Cooling system

A combined engine/hydraulic oil cooler (for the diesel engine and the hydraulic oil) is located at the rear of the machine.

The indicators on the instrument panel of the machine allow you to constantly monitor the engine and hydraulic oil temperatures, and the coolant temperature and level.

Safety instructions

Safety instructions

Safety instructions Mandatory safety shutdown procedure

Before operating this equipment, read and study the following safety information. In addition, be sure that every individual who operates or works with this equipment is familiar with these safety precautions.

Before leaving the machine:

• Lower the working equipment to the ground and support it securely.

• Reduce throttle and turn off the engine.

• Lock out controls by raising right-hand control console.

• Remove the ignition key and take it with you.

Unauthorized modifications

Any machine modification made without authorization from Mustang could create a safety hazard, for which the machine owner would be responsible.

For safety reasons, use only genuine Mustang parts. For example, using incorrect fasteners could lead to a condition in which the safety of critical assemblies is dangerously compromised.

Attachment precautions

Optional kits are available through your dealer. Because Mustang cannot anticipate, identify and test all of the attachments that owners may wish to install on their machines, please contact Mustang for information on approval of attachments, and their compatibility with optional kits.

Operational safety

Control the machine cautiously and gradually until you are fully familiar with all the controls and handling.

Avoid high-voltage lines. Serious injury or death can result from contact or proximity to high-voltage electric lines. The bucket or boom does not have to make physical contact with power lines for current to be transmitted. Use a spotter and hand signals to keep away from power lines not clearly visible to the operator.

Depending upon the voltage in the line and atmospheric conditions, strong current shocks can occur if the boom or bucket is closer than 10’ (3 m) to the power line. Very high voltage and rainy weather can further increase the safe operating distance.

Before starting any type of operation near power lines (either above-ground or buried cable-type), always contact the power utility and establish a safety plan with them.

Before starting to dig, contact authorities. Contact Diggers Hotline One-Call Information at 1-888-258-0808.

Below-ground hazards also include natural gas lines, water mains, tunnels and buried foundations. Know what is underneath the work site before starting to dig.

Be aware of height obstacles. Any object in the vicinity of the boom could represent a potential hazard, or cause the operator to react suddenly and cause an accident. Use a spotter or signal person when working near bridges, phone lines, work site scaffolds, or other obstructions.

Use care on loose ground. Carrying heavy loads over loose, soft ground or uneven, broken terrain can cause dangerous side-load conditions and possible tipover and injury.

Traveling with a suspended load or an unbalanced load can also be hazardous.

If temperatures are changing, be cautious of dark and wet patches when working or traveling over frozen ground. Stay away from ditches, overhangs and other weak support surfaces.

Never rely on jacks or other inadequate supports when maintenance work is being done.

Use solid support blocking.

Printed in U.S.A.

15

918134/CP0807

Safety instructions Overhangs are hazardous. Digging under an overhang is dangerous. Know the height and reach limits of the attachment and plan ahead while working. Avoid creating dangerous situations caused by moving around the work site while working. Move to another digging area before large overhangs are formed. Working around deep pits or along high walls or trenches may require support, especially after heavy rainfalls or during spring thaws. Park the machine away from overhangs.

Sloping terrain requires caution. Dig evenly around the work site whenever possible, trying to gradually level any existing slope. If it is not possible to level the area or avoid working on a slope, reduce the cycling rate and size of the load.

On sloping surfaces, use caution when positioning the machine prior to starting a work cycle. Stay alert for instability situations. Lifting the bucket too high while the boom is turned uphill can also be hazardous.

Stay alert for people moving through the work area. When loading a truck you should always know where the driver is.

Avoid loading over the cab of a truck, even if the driver is in a safe spot, because someone else could have gone inside.

Slow down the work cycle and use slower travel speeds in congested or populated areas.

Use commonly understood signals so that other members of the work crew can warn the operator to slow or halt work in a potentially hazardous situation.

Operate ONLY while seated at operator’s station. Never reach in through a window to work a control. Do not try to operate the machine unless you’re in the operator’s position, seated at the controls. Stay alert and focused on your work at all times.

Use a signal person if you cannot see the entire work area clearly.

Replace damaged safety decals and lost or damaged Operator’s Manuals.

Do not let anyone operate the machine unless they have been fully trained in safety and in operation of the machine.

DO NOT raise or lower a loaded bucket suddenly. Abrupt movements under load can cause serious instability.

Before starting the engine

Do a safety check:

• Walk around the machine before getting in the cab. Look for leaking fluids, loose fasteners, misaligned assemblies and other possible equipment hazards.

• The operator’s compartment, steps, and hand grips must be free of oil, dirt, ice and unsecured objects.

• The lighting system must be checked for proper working condition before working in darkness.

• Always keep the windshield and windows clean. Poor visibility can cause accidents.

• All equipment covers and safety guards must be in place while the machine is being operated, to protect against injury.

• Look around the work site area for potential hazards, and for people or property that could be at risk while operation is in progress.

• NEVER start the engine if there is any indication that maintenance or service work is in progress, or if a warning tag is attached to controls in the cab.

• Check gauges and displays for normal operation prior to and after starting the engine.

Listen for unusual noises and remain alert for other potentially hazardous conditions.

• Never use ether starting aids. Glow plugs are used for cold weather starting. Glow plugs can cause ether or other starting fluid to detonate, causing injury.

• Before starting or moving the machine, warn any personnel in the area.

Printed in U.S.A.

16

918134/CP0807

Safety instructions General safety rules Only trained and authorized personnel, with a full awareness of safe procedures, may be allowed to operate or perform maintenance or service on the machine.

All personnel at the work site should be aware of assigned individual responsibilities. Communication and hand signals used should be understood by everyone.

Terrain and soil conditions at the job site, approaching traffic, weather-related hazards and any above or below ground obstacles and hazards should be observed and monitored by all work crew members.

Unless necessary for servicing the engine, the engine hood must not be opened while the engine is running.

Engine exhaust gases can cause unconsciousness and fatalities. Ensure adequate ventilation before starting the engine in an enclosed area.

Operators should also be aware of any open windows, doors or ductwork into which exhaust gases may be carried, exposing others to danger.

Use a signal person in high traffic areas and whenever the operator’s view is not clear, such as when traveling in reverse.

Make sure that no one comes inside the working area of the machine.

Anyone standing near the machine is at risk of being caught between moving parts of the machine.

Never allow anyone to ride on any part of the machine or attachment, including any part of the boom or operator’s cab.

Fire hazards

The machine has several components that operate at high temperature under normal operating conditions, primarily the engine and exhaust systems. Also, the electrical system, if not properly maintained or if damaged, can arc or produce sparks. These conditions make it extremely important to avoid circumstances where explosive dust or gases can be ignited by arcs, sparks or heat.

The machine must be cleaned on a regular basis to avoid the buildup of flammable debris such as leaves, straw, etc. Accumulated debris, particularly in the engine compartment, poses a fire hazard.

Add fuel, oil, antifreeze and hydraulic fluid to the machine only in a well ventilated area.

The machine must be parked with controls, lights and switches turned off. The engine must be turned off before refueling or service checks are performed.

Static electricity can produce dangerous sparks at the fuel-filling nozzle. In very cold, dry weather or other conditions that could produce static discharge, keep the tip of the fuel nozzle in constant contact with the neck of the fuel-filling nozzle, to provide a ground.

Make sure that the static line is connected from the machine to the service truck before fueling begins.

Keep fuel and other fluid reservoir caps tight and do not start the engine until caps have been secured.

Jump-starting or charging battery

Turn off all electrical equipment before connecting leads to the battery, including electrical switches on the battery charger or jump-starting equipment.

When jump-starting from another machine, do not allow the machines to touch. Wear safety glasses or goggles while battery connections are made.

DANGER! Explosion Hazard – Electrical spark can cause battery to explode.

Connect positive cable first when installing jumper cables. The final cable connection, at the metal frame of the machine being charged or jump-started, should be as far away from the batteries as possible.

Printed in U.S.A.

17

918134/CP0807

Safety instructions Disconnect the negative cable first when removing the jumper cables. For instructions refer – see Battery on page 119.

Travel precautions

Loader control lever should not be operated while traveling. Be sure to lock out the control lever during travel.

IMPORTANT! Do not change selected travel mode (FAST/SLOW) while traveling.

Travel with the bucket or attachment as low as possible [8”-12” (200 mm-300 mm)] to the ground.

Never travel over obstacles or slopes that will cause the machine to tilt severely. Travel around any slope or obstacle that would cause a tilt greater than 10º.

Operate carefully on snow and ice and in very cold temperatures.

In cold weather, avoid sudden travel movements and stay away from even very slight slopes. The machine can slide sideways on icy slopes.

Snow accumulation can hide potential hazards. Use care while operating and while using the machine to clear snow.

Parking the machine

When shutting down the machine for the day, plan ahead so that the machine will be on a firm, level surface away from traffic and away from high walls, cliff edges and any area of potential water accumulation or runoff. If parking on an incline is unavoidable, block the wheels to prevent movement. Lower the bucket to the ground. There should be no possibility of unintended or accidental machine movement.

After the machine has been parked properly, shut down the engine and cycle all controls to release any remaining hydraulic system pressure. Be sure all switches and operating controls are in the OFF position and the right-hand console is raised, locking out the hydraulic functions.

Applications with lifting gear

Definition: Applications with lifting gear are used for raising, transporting and lowering loads with the help of load-securing devices (e.g., slings, chains). In doing so, the help of persons is necessary for securing and detaching the load. For example, get help from other people when lifting and lowering pipes, culverts or containers.

• The machine may only be used with lifting gear if the necessary safety devices are in place and functional.

Safety instructions Additional safety equipment WARNING! Severe operation may require use of additional safety equipment.

Work in mines, tunnels, deep pits or on loose or wet surfaces could produce the hazard of falling rock, roll over or falling objects.

Any operator protective system installed on the machine must comply with applicable safety standards and carry appropriate decaling and rating information.

Never attempt to alter or modify the protective structure, by drilling holes, welding or relocating fasteners. Any serious impact or damage to the system requires a complete integrity re-evaluation, and the replacement of the system may be necessary.

Install additional safety equipment if conditions require

When working with a hydraulic breaker, a front guard over the windshield may be required.

Laminated glass or polycarbonate protection for the front, side or rear windows may also be recommended depending upon particular work conditions.

Contact your Mustang dealer for available safety guards and/or recommendations if there is any risk of being hit by objects that could strike the operator’s cab.

Keep a fire extinguisher at hand

It is recommended that a 5 lb. (2.27 kg) or larger, multi-purpose “A/B/C” fire extinguisher be mounted in the cab. Check the fire extinguisher periodically and be sure that work site crew members are trained in its use.

Seat belt must be used at all times

When the engine is running, the operator must be seated at the control station with the seat belt fastened.

Safety reminders Exposure to crystalline silica

Exposure to crystalline silica (found in sand, soil and rocks) has been associated with silicosis, a debilitating and often fatal lung disease. A Hazard Review (Pub. No. 2002-129) by the U.S. National Institute for Occupational Safety and Health (NIOSH) indicates a significant risk (at least 1 in 100) of chronic silicosis for workers exposed to inhaled crystalline silica over a working lifetime. NIOSH recommends an exposure limit of 0.05 mg/m3 as a time-weighted average for up to a 10-hr workday during a 40-hr work week. NIOSH also recommends substituting less hazardous materials when feasible, using respiratory protection, and regular medical examinations for exposed workers.

Maintain safety equipment in good condition

Machinery guards and body panel covers must be in place at all times. Keep clear of rotating parts, such as cooling fan and alternator belts, which could catch hair, jewelry or loose clothing.

Safety-critical parts must be replaced periodically

Replace the following potentially fire-related components as soon as they begin to show signs of deterioration: Fuel system flexible hoses, fuel tank overflow drain hose and the fuel filler cap.

Hydraulic system hoses, especially the pump outlet lines.

Keep mounting brackets, hose, and cable routing ties tight. Hose routings should have gradual bends.

High pressure hydraulic lines can store energy

Exposed hydraulic hoses on the boom could react with explosive force if struck by a falling rock, overhead obstacle or other job site hazard. Extra safety guards may be required.

NEVER allow hoses to be hit, bent or interfered with during operation.

Operator’s cab should be kept clean

Cleaning off accumulations of grease and dirt helps extend equipment service life. Cleaning also provides an opportunity to inspect equipment. Minor damage can be repaired or corrected before major problems result.

Maintenance safety ☞ Use proper tools • While working on the machine, never use inadequate tools. They could break or slip, causing injury, or they may not adequately perform intended functions.

☞ Battery electrolyte and explosive gases can be lethal • Flush eyes with water for 10-15 minutes if battery acid is splashed on the face.

Anyone who swallows acid must have immediate medical aid. Call the Poison Control Center listing in the telephone directory.

• Sparks can set off explosive battery gas from incidental contact or static discharge.

Turn off all switches and the engine when working on batteries. Keep battery terminals tight. Contact between a loose terminal and post can create an explosive spark.

☞ Disconnect batteries for electrical service and before electrical welding • Remove cable to negative terminal first when disconnecting a battery. Connect positive terminal cable first when installing a battery.

☞ Use warning tag/control lockout procedures during service • Alert others that service or maintenance is being performed and tag operator’s cab controls — and other machine areas if required — with a warning notice.

☞ Do not run the engine if repairs or work is being performed alone • You should always have at least two people working together if the engine must be run during service.

☞ Always use adequate equipment supports and blocking • Lower bucket to the ground before leaving the operator’s seat. Do not work under any equipment supported solely by a lift jack.

☞ Do not work on hot engines, cooling or hydraulic systems • Wait for the engine to cool after operation. Park the machine on a firm, level surface and lower all equipment before shutting down and switching off controls. When engine lube oil, gearbox lubricant or other fluids require changing, wait for fluid temperatures to decrease to a moderate level before removing drain plugs.

IMPORTANT! Engine oil will drain more quickly and completely if it is warm. Do not drain hot fluids, e.g., 200° F (95° C), but do not wait for full cool-down either.

☞ Cool-down is required prior to radiator or hydraulic reservoir checks • Stop the engine and allow it to cool before performing service on the engine radiator or hydraulic reservoir. Both assemblies have pressure vents at the filler cap for venting pressure. LOOSEN CAPS SLOWLY. Vent the pressure before removing the filler caps.

• Release hydraulic system pressure by cycling controls and releasing hydraulic reservoir pressure before removing hydraulic reservoir access cover. The hydraulic reservoir is pressurized. Vent the system pressure by rotating the filler cap.

LOOSEN CAP SLOWLY prior to removal.

Operation Jump-starting the engine

Safety instructions DANGER! Never jump-start the engine if the battery of the machine is frozen, because there is a risk of explosion. The Model ml48 must not touch the jump-starting machine because when both machines are connected by jump leads, there is a risk of sparking.

• The external power source must deliver 12-V; higher supply voltages will damage the electrical systems of both machines.

• Only use authorized jumper cables that are in good condition.

IMPORTANT! The jumper cable connected to the positive (+) terminal of the starting battery must never touch electrically conductive machine parts, because there is a risk of short circuit.

• Route the jumper cables so that they cannot catch on rotating components in the engine.

Procedure

☞ Start the engine of the jump-starting machine. ☞ Connect one end of the red jump lead (+) to the + terminal of the dead battery, then connect the other end to the + terminal of the starting battery.

Dead battery

12 V

☞ Connect one end of the black jump lead (–) to the – terminal of the starting battery. ☞ Clip the other end of the black jump lead (–) onto the engine block.

DANGER! DO NOT connect the other end of the jump lead to the negative terminal of the dead battery, because gas emerging from the battery may ignite if sparks are formed.

☞ Start the engine of the machine with the dead battery.

12 V Starting battery

After the engine has started:

☞ While the engine is running, disconnect both jump leads in exactly the reverse order (first remove the – terminal, then the + terminal) – this prevents sparking near the battery).
