MAINTENANCE
Clean and replace the fuel filter frequently.
Clean electrical components, especially the starting motor and alternator, to avoid accumulation of dust.
When inspecting or changing the oil, move the machine to a place that is free of dust to prevent dirt from getting
into the oil.
Avoid Mixing Lubricants
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. Never mix different brand or grade of oil.
Cover on Right Side of the Machine
If the cover on the right side of the machine is fully opened and the boom is swung to the right, there is danger that
the boom may hit the cover and break it.
If the boom must be swung to the right with the cover open, set the cover so that it is half-open.
Locking the Inspection Covers
Lock inspection cover securely into position with the lock bar. If inspection or maintenance is performed with
inspection cover not locked in position, there is a danger that it may be suddenly blow shut by the wind and cause
injury to the worker.
Hydraulic System - Air Bleeding
After repairing or replacing the hydraulic equipment or after removing the hydraulic piping, it is necessary to bleed
the air from the circuit. For details, see "BLEEDING AIR FROM HYDRAULIC SYSTEM (PAGE 4-42)".
Hydraulic Hose Installation
When removing parts at locations where there are O-rings or gasket seals, clean the mounting surface, and
replace 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 or bend them into loops with a small radius.
This will cause damage to the hose and drastically reduce its service life.
Checks After Inspection and Maintenance Works
If you forget to perform the checks after inspection and maintenance, unexpected problems may occur, and this may
lead to serious injury or property damage. Always do the following:
Checks after operation (with engine stopped)
Have any inspection and maintenance points been forgotten?
Have all inspection and maintenance items been performed correctly?
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.
Are there any leakage of coolant or oil? Have all nuts and bolts been tightened?
Checks when operating engine
For details of the checks when operating the engine, see "TWO WORKERS FOR MAINTENANCE WHEN
ENGINE IS RUNNING (PAGE 2-35)" and pay careful attention to safety.
Are the inspection and maintenance items working properly?
Is there any leakage of fuel or oil when the engine speed is raised?
Use of Fuel and Lubricants According to Ambient Temperature
It is necessary to decide the type of fuel and lubricants according to the ambient temperature.
For details, see "LUBRICANTS, FUEL AND COOLANT SPECIFICATIONS (PAGE 4-9)".
