DUSTY JOBSITES
When working at dusty jobsites, observe the following.
• Inspect the dust indicator frequently to see if the air cleaner is dirty or clogged.
• 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 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
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.
LOCK INSPECTION COVERS
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
personal injury.
PRECAUTIONS WHEN SWINGING BOOM
When the mud cover at the right side of machine is opened for inspection and maintenance, if you swing the
boom to right, do it with the dirt cover opened half way.
If the dirt cover is fully opened, it may interfere with the boom and be damaged.
PRECAUTIONS WHEN OPENING AND CLOSING COOLING COVER
If the cooling cover at the right side of machine is fully opened with the blade raised, the cooling cover may in-
terfere with the blade and be damaged.
When the cooling cover is opened for testing or maintenance, etc., lower the blade to the ground or bring the
blade to the opposite side of the cooling cover.
BLEED AIR FROM HYDRAULIC CIRCUIT
When hydraulic equipment is repaired or replaced, or the hydraulic piping is disconnected, the air must be bled
from the circuit.
PRECAUTIONS WHEN INSTALLING HYDRAULIC HOSES
• 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 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 extremely shortened and they may be damaged.
