MAINTENANCE
DO NOT DROP THINGS INSIDE MACHINE
When opening inspection windows or the oil filler port of the tank to carry out inspection, be careful not to drop
nuts, bolts, or tools inside the machine.
If such things are dropped inside the machine, it will cause damage and malfunction of the machine, and will
lead to failure. If you drop anything inside the machine, always remove it immediately.
Do not put unnecessary things in your pockets. Carry only things which are necessary for inspection.
DUSTY JOBSITE
When working at dusty worksites, do as follows:
Check the clogging of the air cleaner more frequently with the dust indicator. Clean the air cleaner element
more frequently.
Clean the radiator core frequently to avoid clogging.
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 get-
ting into the oil.
AVOID MIXING LUBRICANTS
Never mix different kinds of oil. If a different type of oil has to be added, drain the old oil and replace all the oil with
the new type of oil.
LOCKING THE INSPECTION COVERS
When carrying out maintenance with the inspection cover open, lock it in position securely with a lock bar. If
inspection or maintenance is carried out with the inspection cover open and not locked in position, there is a haz-
ard that it may be suddenly blown shut by the wind and cause injury to the worker.
HYDRAULIC SYSTEM - AIR BLEEDING
When hydraulic equipment has been repaired or replaced, or the hydraulic piping has been removed and installed
again, the air must be bled from the circuit. For details, see "Air Bleeding (PAGE 4-49)".
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 them or bend them into loops with a small radius.
This will cause damage to the hose and markedly reduce its service life.
