1 - GENERAL INFORMATION

INTRODUCTION The E85CMSR excavator is a hydraulically operated machine. It consists of an undercarriage fitted with tracks and a swing bearing which supports the upper frame. The upper frame supports the attachment, the engine, the hydraulic components, the cab, the fuel tank and the counterweight. When the operator activates the controls (pedals/levers), the hydraulic pumps, operated by the engine, sucks the oil from the tank, sending it to the control valve which sends the oil to perform the request operation. A cooling system maintains the hydraulic oil at normal operating temperature.

Vibration to the operator

• use equipment compatible with the machine and the type of work do be done;

This machine is equipped with an operator's seat complying with the requisites of standard ISO 7096:2008. This ensures that the exposure of the operator's body to vibrations comply with the protection requisites for the protection against vibrations when the machine operates as required by the operational scopes, in accordance with the prescriptions of this Manual. The operator’s seat has been tested in accordance with EM6 input spectral class and has a SEAT transmissibility factor < 0.7.

• adjust and lock the seat in the correct position; also inspect regularly the suspensions of the seat, performing the adjustments and repairs as required;

• The weighted average quadratic acceleration value to which the operator’s arms are subjected does not exceed 2.5 m/s².

• perform regularly the current maintenance operations of the machine at the prescribed intervals;

• The weighted average quadratic acceleration value to which the operator’s body is subjected does not exceed 0.5 m/s². These results were obtained using an acceleration gauge while digging ditches.

The vibration level transmitted to the operator depends mainly upon the conditions of the ground on which operations take place, the mode of operation of the machine and its equipment. The exposure to vibrations can be considerably reduced when the following recommendation are complied with:

• operate the equipment in a uniform manner, preventing, as far as possible, sharp movements or excessive loads; • when travelling, avoid, as far as possible, particularly rough terrain or the impact against possible obstacles.

NOTE: the Whole-Body exposure value is determined under particular operating and terrain conditions and therefore may not be representative for all the possible operating conditions within the intended use of the machine.

Auto accel switch ATTENTION: when loading or unloading machine on trailer, turn the auto accel switch Off. If it is operated keeping the accel switch On, the engine speed changes suddenly.

Do not operate the machine in "Auto acceleration switch ON" to avoid abrupt speed change of engine. Abrupt speed change causes the machine fall from the deck of trailer.

On the condition that "Auto acceleration switch (9) is turned ON" and "Throttle dial is set to 1200 RPM or more", when the control lever and / or pedal are not operated for 4 s or more, the engine speed changes to 1200 RPM automatically.

When the control lever and / or pedal are operated, the engine speed returns to the throttle dial set level. When the acceleration switch is turned off, the auto acceleration function does not work. As a result, the engine speed does not change.

While the auto acceleration is working, this switch is turned off, and the engine speed rises to the auto acceleration set speed.

Lowering attachment when sudden engine failure occurs How to lower attachment Fig. 1 NOTICE: when you need to lower the attachment in an emergency, handle the holding valve at first, secondly loosen the port relief valve of the main control valve.

When engine stops because of troubles, the relief valve incorporated in the holding valve mounted on the boom cylinder head side is available to lower attachment.

ATTENTION: be careful when lowering attachment. Do not stand under boom.

Manual operation for the relieving of holding valve 1. Loosen the lock nut (1).

2. Rotate the thread (2) four turns clockwise to tighten, and the inner spool valve is switched. Consequently, the holding valve (3) is relieved forcibly.

3. To return to the active state of the holding valve (3) , rotate the thread (2) counterclockwise fully to the end.

Emergency manual valve for lowing attachment Fig. 2.

Emergency manual valve (5) for lowing attachment is equipped internally between A8 port (4) of boom cylinder head side and boom lock valve. For safety, this valve lowers rifted attachment to the ground, if the machine stops with engine trouble. Only in case that boom is lowering, the pressure in the cylinder of attachment can be released by operating arm or bucket control lever.

Functional explanation In normal cases, this valve was blocked completely to prevent pressure leak of boom circuit.

Lowering of boom Loosen lock nut (1) at first and loosen the lock screw (2) to the end of contact.

ATTENTION: this valve is provided the mechanism of stopper against falling out. But the mechanism might cause break by undue force.

The oil of boom cylinder head side flows into drain passage through orifice, and boom lowers slowly. The time of boom lowering to the ground takes about 4 - 8 min in accordance with machine position and holding pressure.

Function of Actuator Oil pressure of ps port (3) is reduced by releasing holding pressure of boom cylinder head side to drain passage through orifice.

Operation of actuator with remote control valve is possible by leading medium pressure via orifice from ps port (3) to shuttle valve. In this function, this leading of medium pressure ensures primary pressure of remote control (source of pressure). This function ensures that the cylinder movement of boom, arm, bucket and others can be actuated only downward by self weight. Consequently the releasing of pressure becomes possible.

But after attachment is lowered to the ground by lowering boom, holding pressure disappears and remote valve is possible.

When the boom cylinder has holding valve, loosen above-mentioned reducing valve assembly together with port relief valve of holding valve, the boom cylinder starts boom lowering.

Spool of holding valve moves to open side by back pressure of port relief valve, and holding pressure of boom cylinder is led to “Emergency manual valve for lowing attachment - Fig. 2 operation of actuator by remote is possible.

- Figure (A) Shows that the refrigerant volume is proper.

- Figure (B) Shows that the refrigerant is over charged. This will make both high and low pressure extreme and exert a bad influence on the pressure switch operation and the air conditioning system.

- Figure (C) Shows that the refrigerant is insufficient. Have the refrigerant recharged at your distributor.

Description

Refrigerant volume (A). Proper

After the air conditioner is turned On, little bubbles appear. The refrigerant becomes transparent, then turns a light milky white.

(B).

Overcharged After the air conditioner is turned On, no bubbles appear.

(C). Insufficient

After the air conditioner is turned On, bubbles appear continuously.

Bubbles

Refrigerant gas is mixed with refrigerant fluid.

No bubbles

Whole refrigerant becomes fluid and transparent.

Cloudy

Refrigerant is separated from oil. The fluid becomes a light milky white.

Objects handling Safety precautions-safety loads lifting • The excavator is a machine designed specifically to perform digging/loading works, thus it must not be used to handle suspended loads. In the event, under exceptional conditions, it becomes necessary to handle materials, the following indications must be strictly implemented.

• The machine must be equipped compulsorily with the appropriate variant provided upon request. Also, totally comply with the safety precautions for the operation of the excavator as a lifting equipment.

• Secure the loads to be raised using cables or chains fastened with appropriate hooking mechanisms.

• Do not hook cables or chains to the bucket teeth.

• Nobody should be allowed to remain under the raised load or within the excavator operating range for any reason whatever.

• Do not exceed specified lifting capacity. Incorrect fastening of slings or chains may cause boom/arm failure or failure of the lifting means with consequent bodily injuries and even death.

• Always ensure that slings and chains used for lifting are adequate to the load and in good condition.

• All lifting capacities are referred to the machine on a level surface and should be disregarded when working on a slope.

TUIL12C140477AA

• In any case, comply with the current national or local regulations on this matter.

1

Objects handling operation ATTENTION: the machine has been specifically designed to perform digging/loading works. The handling of suspended loads completing the digging cycle is allowed, providing that the machine is equipped with the appropriate variant supplied upon request. Handle suspended loads, following strictly all current regulations regarding this matter, as well as the rules described in the “SAFETY PRECAUTIONS” chapter.

ATTENTION: the anti-drop valves located on the cylinders, the warning buzzer device, the table of the loads that can be lifted located in the cab and the hook on the link of the bucket linkage are SAFETY DEVICES, making part of the suspended load handling variant. The lack of one of them or a damaged item make the machine unfit for works handling suspended loads.

To handle suspended loads, act as described here below: ATTENTION: prior to starting any handling of suspended loads, check that the valves do not show clear evidence of damages or abnormal noises. In the event abnormal conditions are found, it is necessary to contact a Dealer, in the meantime, do not use the machine for the handling of suspended loads.

Check that the lifting devices (hooks, chains etc.) are in perfect conditions without any sign of excessive wear. In any case, comply with current regulations in effect for these devices (non supplied with the machine).

ATTENTION: in order to prevent injuries, do not exceed the nominal load capacity of the machine. If the machine is not on a flat surface, the load capacity is reduced. In any event, proceed always with extreme care.

ATTENTION: do not offset the boom when you intend to lift the load. To avoid injury death, lift the load when the boom is facing front straightly.

If you lift the load in the offset condition, the machine may tip over. It may cause severe injury or death.

1. Set an engine speed appropriate for the hydraulic load required.

2. Evaluate (if known) the mass of the object to be handled and compare it with the data listed in the table located in the cab.

Do not lift loads exceeding the maximum values prescribed by the table.

3. Prior to performing lifting operations, press switch (1) to activate the load-momentum sensor. This sensor, once the safety limit is reached, activates the sound warning device.

4. Secure the load with the appropriate hook (2) located on the bucket linkage rod, using slinging devices and chains adequate for the load to be lifted.

TUIL12C140478AB

2

ATTENTION: check that the lifting devices (hooks, chains etc.) are safe and free from signs of excessive wear. In any case, comply with current regulations relative to the inspection of such devices (not provided with the machine). The device can be used exclusively for the lifting of parts not placed on the ground. Do not use it for towing operations, uprooting or tearing apart.

5. In order to limit the swinging of the load, avoid slinging it with cables and/or chains too long.

6. Check the surrounding working area and make sure that the path to be travelled with the load is free from obstacles.

7. Lift slowly the load, avoiding sharp movements which could cause swinging of the load. Keep the load near the machine, to improve the stability and operate, preferably, along its longitudinal axis, rather than crossways. Lift the load from the ground the minimum height required.

8. Position and place the load where desired, making sure that it is resting on a solid base appropriate for its mass.

9. Remove the chains.

TUIL12C140479BB

ATTENTION: suspended load can swing and rotate in all directions, thus there is the dangerous possibility that they can hit persons or the cab of the machine. In order to limit this danger, it is absolutely required that all bystanders are moved away from the field of action of the machine and that the load is handled slowly. In the event the load rotates or swings during the handling, slow-down until stopped and lower it slowly to the ground; then correct the way it is slung.

ATTENTION: in the event the sound alarm is activated during the handling of the load, place the load onto the ground and check the load conditions making reference to the appropriate table in the cab.
