With the machine on level ground, remove the radiator
cap. If the coolant level is below the filler neck, add a
low-silicate ethylene glycol base coolant mixed with
quality water and supplemental coolant additives
(SCAs) suitable for heavy duty diesel engines. See
your engine manual for additional information.
Replace the radiator cap securely.
NOTE: If the engine is operated with a loose
radiator cap, the pressure bypass will not work
and the engine will run hot.
CHECKING TRANSMISSION OIL LEVEL
The machine must be on level ground. With the engine
and transmission at operating temperature parking
brake on, transmission in neutral and engine speed at
low idle, remove the access cover to the transmission
and hydraulic pump. Remove the dipstick and check
the oil level. Add the required amount of oil to bring
the level to the FULL mark. See the Lubrication chap-
ter for the type of oil to use.
CHECKING HYDRAULIC OIL LEVEL
The machine must be on level ground with boom low-
ered and completely retracted. The fluid MUST be cool
when checking the reservoir level, to reduce the possi-
bility of overfilling the hydraulic system.
Visually check the level of the hydraulic oil through
the sight gauge located on the right side of the front
hood. If low, remove the front access cover from the
front hood to replenish the oil through the filler cap.
See the Lubrication chapter for the type of oil to use.
IMPORTANT: Be careful when removing the
reservoir filler cap so that no dirt or other foreign
matter enters the hydraulic system. DO NOT
OVERFILL.
CHECKING BRAKE RESERVOIR LEVELS
Flip up the cover on the cab floor in front of the seat.
Remove both reservoir covers to check the fluid levels.
If low, fill to the proper level with the correct fluid. See
the Lubrication chapter for the type of fluid to use.
CHECKING TIRE PRESSURES
Proper tire pressure should be maintained for all four
tires to enhance operating stability and extend tire life.
When installing tires on the machine, be sure that all
tires are of the same size and style. ALWAYS replace
tires with the same size furnished as original equip-
ment. Replacement tires must be purchased locally.
Check the tire pressure “cold.” All 12-ply tires should
be inflated to 70 psi (480 kPa).
NOTE: If the tires have been filled with water or
calcium chloride for balast, a calcium chloride tire
pressure gauge MUST be used to check the tire
pressure.
When removing tires, follow industry safety practices.
Deflate completely prior to removal. After assembly of
the tire onto the rim, use a safety cage or restraining
device while inflating.
WARNING
Inflating or servicing tires can be dangerous.
Whenever possible, trained personnel should
service and mount tires. To avoid possible
death or serious injury, follow the safety pre-
cautions below:
1. BE SURE the rim is clean and free of rust.
2. Lubricate both the tire beads and rim
flanges with a soap solution. DO NOT use
oil or grease.
3. DO NOT place your fingers on the tire bead
or rim during inflation. Use a clip-on tire
chuck with a remote hose and gauge,
which allows you to stand clear of the tire
while inflating it.
4. NEVER inflate beyond 35 psi (240 kPa) to
seat the beads. If the beads have NOT
seated by the time the pressure reaches 35
psi (240 kPa), deflate the assembly, reposi-
tion the tire on the rim, relubricate both
parts and re-inflate. Inflation pressure
beyond 35 psi (240 kPa) with unseated
beads may break the bead or rim with
explosive force sufficient to cause death
or serious injury.
5. After seating the beads, adjust the inflation
pressure to the recommended operating
pressure listed.
6. DO NOT weld, braze, or otherwise attempt
to repair and use a damaged rim.
