DUSTY WORKSITES:
When working at dusty worksites, do as follows:
q
Check the air cleaner clogging caution pilot lamp more frequently to check the degree of clogging of the air
cleaner.
Clean the air cleaner element more frequently.
q
Clean the radiator core frequently to avoid clogging.
q
Clean and replace the fuel filter frequently.
q
Clean electrical components, especially the starting motor and alternator, to avoid accumulation of dust.
q
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 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. Never mix different brand or grade of oil.
OPENING AND CLOSING OF INSPECTION COVER
When opening and closing the inspection cover, take care not to get a hand or finger pinched.
LOCKING 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.
BLEEDING AIR FROM HYDRAULIC CIRCUIT:
After repairing or replacing the parts of hydraulic circuit, or removing the piping of hydraulic circuit, it is necessary
to bleed the air from inside of the circuit. See “BLEEDING AIR FROM HYDRAULIC TANK (4-37)“ for bleeding the
air.
PRECAUTIONS WHEN INSTALLING HYDRAULIC HOSES:
q
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.
q
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.
