CHAPTER 7 - Maintenance
7.4.2
MACHINE CHECK PROCEDURE WITH MOTOR OFF.
Place the machine on a fl at surface and ensure there can be no accidental shifting.
Engage the parking brake and insert stop wedges on the wheels of the machine.
Open the motor compartment and ensure that there are no leaks either on the motor or hydraulic connections and that all parts are in good working
order.
Below are the instructions for checking the various parts of the machine to be done only and exclusively with motor off.
7.4.2.1
HYDRAULIC SYSTEM OIL
At the operating temperature the hydraulic oil is HOT.
Avoid contact with the skin and/or parts of the body.
Pay attention not to let any dirt enter the system while checking the oil level or while replacing the fi lter.
Never operate the hydraulic pump without oil in the hydraulic circuit.
Dry operation of the hydraulic pump without oil will irreparably damage the pump.
The hydraulic oil level must be checked when the oil is at operating temperature, and the machine is stationary with the motor off.
Only top up with suitable oil to the level mark.
If too much hydraulic oil is added, it will seep out of the vent during operation.
The oil level indicated by the dipstick is more precise when the oil temperature is between 50°C / 122°F and 90°C / 194°F.
We would like to remind you of the requirement to comply with applicable laws on the disposal of mineral oils.
7.4.2.2
PIPING
Periodically replace the following important components for fi re prevention.
Supply system: fuel delivery and return pipes.
Hydraulic system: main delivery pipes of the hydraulic pump and connecting piping to the hydraulic motors.
Even if they appear to be in good condition, these components must be replaced periodically with new piping. Over time, in fact, these components
tend to deteriorate.
Should one of these parts turn out to be faulty, replace it immediately.
Do not forget that working circuits are always pressurised; that is why, when hydraulic oil needs to be added or drained, maintenance or inspection of
the hydraulic circuit should only be carried out after discharging the residual pressure.
Small leaks from pressurised pipes and the sprays from them are highly dangerous and harmful since they may damage the skin and enter the
bloodstream or hit your eyes in the event of contact.
That is why appropriate gloves and goggles should always be worn during inspections.
Should you be hit by a jet of high pressure oil or even slightly injured, immediately seek medical attention for a dressing and suitable treatment
Precautions when performing maintenance with high temperatures and high pressure
When the machine is stopped at the end of work, motor cooling liquid, oil and all parts are hot and the hydraulic circuits are pressurised.
If the cooling liquid, hydraulic oil and motor oil need to be drained to be replaced or for the fi lters to be replaced, the conditions are more hazardous,
including severe burn hazard.
Perform the maintenance and procedures set out in the maintenance section of this manual, only when the temperatures fall back within normal
parameters (30-35°C / 86-95°F).
Handling high pressure pipes
Do not bend or rub high pressure pipes with abrasive or sharp objects.
Do not use bent or cracked pipes or hoses that have already been scrapped due to leaks or fastening defects as they might burst during use.
Always repair or replace any loosened or defective fuel or oil pipe. Any fuel or oil leak may cause a fi re.
7.4.2.3
FUEL SUPPLY SYSTEM
It is strictly forbidden to use naked fl ames to check the fuel level or check for any leaks in the system.
All fuels are highly fl ammable and may burn or cause an explosion.
Should a fuel leak be detected contact the Manufacturer for information on how to proceed.
Do not forget that fuel containers, even when empty, may cause explosion hazard due to fuel vapours.
Never operate the machine until the repair has been properly performed.
Check the fuel supply system to ensure there are no leaks.
To perform refuelling, the engine needs to be turned off and the key must be turned to “OFF”.
Upon completing refuelling, ensure that there have been no leaks or spills before closing the tank cap well and restarting the engine.
In the event of spills dry and clean up any traces of fuel.
Refuelling must be exclusively carried out in areas specifi cally intended for the purpose and fi tted with the safety features (fi re systems, etc.) set forth
by the regulations in force in the country of use of the machine.
The engine must not be restarted until the fuel dispenser has been removed, the fuel cap/s has/have been replaced and any spilled fuel has been
mopped up.
Ensure the right fuel is dispensed for the type of engine.
