SAFETY INSTRUCTIONS SAFETY IS THE OPERATOR’S RESPONSIBILITY The Bobcat Hydraulic Excavator is a maneuverable, compact machine. In operation, it is rugged and useful under a wide variety of conditions. This presents an operator with hazards associated with off highway, rough terrain applications. The Hydraulic Excavator has an internal combustion engine with resultant heat and exhaust. All exhaust gases can kill or cause illness so the Bobcat Hydraulic Excavator must be run with adequate ventilation.

The dealer explains the capabilities and restrictions of the excavator and attachments for each application. The dealer demonstrates the safe operation of the excavator according to Melroe’s instructional materials; which are also available to all operators. The dealer can also identify unsafe modifications or use of unapproved attachments. The attachments are designed for rated capacity and secure fastening to the Bobcat Hydraulic Excavator. The user must check with the dealer or Melroe Company literature or load diagram to identify safe loads.

The following publications provide information on the safe use of the excavator and attachments: • The Delivery Report is used to check whether complete instructions have been given to the new owner, and that the machine is in safe operating condition.

• The Operation & Maintenance Manual delivered with each Bobcat Hydraulic Excavator gives operating information as well as routine maintenance information. It is part of the machine and must stay with the machine when it is sold.

Replacement Operation & Maintenance Manuals can be purchased from your dealer.

• Every Bobcat Hydraulic Excavator has machine signs (or decals) which instruct on the safe operation and care. The signs and their location are shown in the Operation & Maintenance Manual. Replacement signs are available from your Bobcat Hydraulic Excavator dealer.

• The Bobcat Hydraulic Excavator has a plastic Operator’s Handbook fastened to the operator cab. It’s instructions are convenient to the operator. The handbook is available from your dealer in an English edition or one of the following languages: French, German, Italian, Dutch, Spanish, Portuguese, Finnish, Danish & Spanish.

• The CIMA safety manual contains information for safe operation and maintenance.

• The Service and Parts Manuals are available from your Bobcat Hydraulic Excavator dealer for use by mechanics to do shop–type service and repair work.

• The dealer and owner/operator review the recommended uses of the excavator and attachments at the time of delivery of the excavator. If change of the use of the excavator occurs, the owner/operator must ask the dealer for recommendations on the new use of the excavator.

SAFE OPERATION NEEDS A QUALIFIED OPERATOR* A QUALIFIED OPERATOR MUST DO THE FOLLOWING:

• UNDERSTAND THE WRITTEN INSTRUCTIONS, RULES AND REGULATIONS • The written instructions from Melroe Company include the delivery report, operator handbook, Operation & Maintenance Manual, CIMA manual and machine signs (decals).

• Check the rules and regulations at your location.

• HAVE TRAINING WITH ACTUAL OPERATION • Operator training must consist of a demonstration and verbal instruction. This training is given by your excavator dealer before the excavator is delivered.

• The new operator must start in an area without bystanders and use all the controls until he can operate the excavator safely under all conditions of the work area.

• KNOW THE WORK CONDITIONS • For each material to be handled, the operator must know how to avoid exceeding the rated lift capacity of the excavator. For example, you should not use the excavator for lifting heavy objects.

• The operator must know any prohibited uses or work areas, for example, he needs to know about excessive slopes.

• Know the location of any underground lines. Call local utilities or ONE CALL before you dig.

• Wear tight fitting clothing. Always wear safety glasses when maintaining or servicing excavator. Safety glasses,

hearing protection or an excavator special application kit are required for some work. See your dealer about Melroe Safety equipment.

325 (S/N 511820001–511821999) Excavator Operation & Maintenance Manual

FIRE PREVENTION The excavator has several components that are at high temperature under normal operating conditions. The primary source of high temperatures is the engine and exhaust system. The electrical system, if damaged or incorrectly maintained, can be a source of arcs or sparks. These conditions make it important to avoid applications where explosive dust or gases can be ignited by arcs, sparks or heat.

Flammable debris (leaves, straw, etc.) must be removed regularly. If flammable debris is allowed to accumulate, it will increase the fire hazard. The excavator must be cleaned as often as necessary to avoid this accumulation. This flammable debris in the engine compartment can be a fire hazard when the machine is parked with a hot engine.

The spark arrestor muffler is designed to control the emission of hot particles from the engine and exhaust system, but the muffler and the exhaust gases are still hot. This spark arrestor muffler does not change the need to avoid use of the excavator in an atmosphere with explosive dust or gases or where the exhaust can contact flammable material.

• Do not use the Hydraulic Excavator where explosive dust or gases can be ignited by arcs, sparks, hot components or exhaust gases.

• The engine compartment and engine cooling system must be inspected every day and cleaned if necessary to prevent overheating. Remove all flammable material.

• Check all electrical wiring and connections for damage. Keep the battery terminals clean and tight. Repair or replace any damaged part.

• Check fuel and hydraulic tubes, hoses and fittings for damage and leakage. Tighten or replace any parts that show leakage. Always clean fluid spills.

• Do not use ether or starting fluids on any engine which has glow plugs. These starting aids can explode and injure bystanders.

• Always clean the excavator before doing any welding. Cover rubber hoses, battery and all other flammable parts. Keep a fire extinguisher near the machine when welding.

• Stop the engine and let it cool before adding fuel. No smoking!

• Use the procedure in Operation & Maintenance Manual for jump starting the battery.

When operating in water or crossing streams, first check the soil conditions, depth and flow of water. Never operate in water higher than the bottom of the swing circle.

OPERATING PROCEDURE Breaking In A New Machine When operating on a public road or highway, always follow local regulations. For example: Slow Moving Vehicle Sign or Directional Signals may be required.

NOTE: Be careful when removing the machine from water. The engine may become filled with water and damage could result.

A new machine requires careful operation during the first 100 hours to break in various parts.

Do not operate the machine when visibility is poor (fog, mist or smoke).

If a machine is subjected to hard use during the initial operation, the performance and service life will be reduced.

Do the following when operating a new machine:

If it is necessary to operate the control levers when moving the machine near a cliff, road shoulders, or sloping ground, stop the machine travel before operating any work equipment levers.

•

After starting, let the engine idle for 5 minutes so the engine and components can warm up.

Do not dig under the machine.

•

Avoid operation with heavy loads or at high speeds.

•

Check with utility companies, for underground electrical, water, gas lines, etc. Work slowly in areas of underground utilities.

Avoid sudden starting or stopping or abrupt motions.

Do not allow the bucket teeth to contact the ground when swinging the upperstructure.

General Operation Suggestions

Do not move the machine with the bucket in the ground or trench.

Know where the first aid kit and fire extinguisher are and know how to use them. Also know how to contact emergency assistance.

Do not use the bucket as a breaker or pile driver. It is better to excavate hard or rocky ground after breaking it with other equipment. This will reduce damage to the machine.

When operating on uneven ground or in places where there are obstacles, do the following:

•

Operate as slow as possible and avoid sudden changes in direction.

•

Avoid traveling over objects (such as rocks, trees, stumps, etc.).

To brake the machine when going down a slope, put the steering levers in NEUTRAL position. This will engage the hydrostatic braking.

When the engine stops on a slope, move the steering levers to the neutral position. Lower the boom/bucket.

When working in wet or soft ground, put planking on the ground to prevent the machine from getting stuck. If the machine is stuck in soft soil, use the following procedure to move the machine to firm ground:

NOTE: The left hand control console must be in the locked down position, with the engine stopped, to activate the accumulator pressure to lower the boom/bucket (attachments) to the ground.

1. If one track or both tracks are stuck in soft soil, push the bucket down against the ground to raise the track (or tracks, one side at a time) off the ground.

2. Place timber (planks) under the track(s) and drive the machine to firm ground.

NOTE: The key switch must be in the ON position with the engine stopped to activate the accumulator pressure to lower the boom/bucket to the ground.

3. It may help to put the bucket into the ground in front and move the arm as if you were digging to help move the machine.

Start the engine and resume the operation.

When going down a slope, control the speed with the steering levers and the speed control lever.

When going down grades that exceed 15 degrees, put the machine in the position shown, and run the engine slowly.

Operate as slow as possible and avoid sudden changes in lever direction.

Avoid traveling over objects (such as rocks, trees, stumps, etc.).

MC–01878C

Stop the machine travel before moving the upper equipment controls. Never allow the blade to strike a solid object. Damage to the blade or hydraulic cylinder can result.

C

RECOMMENDED POSITION FOR WORKING ON A SLOPE

When working on a slope, it is recommended to level the work area [C].

If this is not possible, the following procedures should be used: Do not work on slopes which are over 15 degrees.

Slow down the work cycle.

Avoid working with the tracks across the slope as this reduces stability and increases the tendency for the machine to slide. Position the excavator with the blade down hill and lowered.

MC–01865C

Avoid swinging or extending the bucket farther than necessary in a down hill direction. When you must swing the bucket down hill, keep the dipper arm low and skid the bucket downhill.

When working with the bucket on the uphill side, keep the bucket as close to the ground as possible. Dump the spoil far enough away from the trench or hole to prevent the possibility of a cave in.

0.5 to 1.0% Above 1.0%

1/2 of Regular Interval 1/4 of Regular Interval

Add premixed coolant; 43% water and 57% propylene glycol to the recover tank if the coolant level is low.

One gallon and one pint of propylene glycol mixed with one gallon of water is the correct mixture of coolant to provide a –34°F (–37°C) freeze protection.

Use a refractometer to check the condition of propylene glycol in you cooling system.

NOTE: Do not mix ethylene glycol and propylene glycol in the same cooling system.
