DUSTY WORKSITES
Dusty worksites:ALL-0000-20HK00A
When working at dusty worksites, do as follows:
q
Clean the radiator fins and other parts of the heat exchange equipment more frequently, and take care not to
let the fins become clogged.
q
Replace the fuel filter more frequently.
q
Clean electrical components, especially the starting motor and alternator, to avoid accumulation of dust.
q
When checking and replacing the oil or filters, move the machine to a place where there is no dust and take
care to prevent dust from entering the system.
AVOID MIXING OIL
Avoid mixing oil:ALL-C940-2A4P02A
Never mix different brand or grade of oil. If a different brand or grade of oil has to be added, drain the old oil and
replace all the oil with the new brand or grade of oil.
LOCKING INSPECTION COVERS
Locking inspection covers:ALL-M190-2AHP00A
Lock inspection cover securely into position with the lock bar etc. If inspection or maintenance is performed with
inspection cover not locked in position, there is a danger that it may be suddenly shut by the wind and cause
injury to the worker.
BLEEDING AIR FROM HYDRAULIC CIRCUIT
BLEEDING AIR FROM HYDRAULIC CIRCUIT:PC-C000-231P01A
When hydraulic equipment is repaired or replaced, or the hydraulic piping is removed and installed again, the air
must be bled from the circuit. When bleeding air, see "BLEED AIR FROM HYDRAULIC CIRCUIT (4-36)".
PRECAUTIONS WHEN INSTALLING HYDRAULIC HOSES
Precautions when installing hydraulic hoses:ALL-CE00-72BP00A
q
When removing parts at locations where there are O-rings or gasket seals, clean the mounting surface, and
replace them with new parts.
When doing this, be careful not to forget to assemble the O-rings and gaskets.

When installing the hoses, do not twist them or bend them sharply.
If they are installed so, their service life will be shortened extremely and they may be damaged.
CHECKS AFTER INSPECTION AND MAINTENANCE
Checks after inspection and maintenance:PC-0000-20JK00A
If you forget to perform the checks after inspection and maintenance, unexpected problems may occur, and this
may lead to serious personal injury. Always do the following:
q
Checks after operation (with engine stopped)
q
Have any inspection and maintenance points been forgotten?
q
Have all inspection and maintenance items been performed correctly?
q
Have any tools or parts been dropped inside the machine? It is particularly dangerous if parts are dropped
inside the machine and get caught in the lever linkage mechanism.
q
Are there any leakage of coolant or oil? Have all nuts and bolts been tightened?
q
Checks when engine running
q
For details of the checks when the engine running, see "TWO WORKERS FOR MAINTENANCE WHEN
ENGINE IS RUNNING (2-45)" and pay attention to safety.
q
Do not run the engine for long hours with the engine hood open. The engine hood may be damaged by
heat of exhaust gas.
q
Is there any leakage of fuel or oil when the engine speed is increased?
q
Are the inspected and maintained parts working properly?
FUEL AND LUBRICANTS TO MATCH THE AMBIENT TEMPERATURE
Fuel and lubricants to match the ambient temperature:ALL-RA19-05AK02A
