7. After the bubbles are completely removed, retighten
the air-bleeding plugs and replace the caps.
8. Refill the brake-fluid-reservoir with the preceding
hydraulic oil to the specified level.
The properties of brake fluid are different from
manufacturer to manufacturer. Use the same brand
of hydraulic oil.

SERVICE FOR TIRES
1. Precautions for handling the tires
WARNING
To avoid personal injury or death:
• Before changing the tires, set the parking brake,
stop the engine, lower the bucket and
attachment to the ground, release the hydraulic
pressure in the hydraulic system by operating
the control levers, lock all control levers in
neutral, and remove the starter key.
• To change the tires, place the machine on
blocks suitable for the weight of the machine.
• Before adding the air, install the tire correctly
on the machine or put the tire in a retaining
device (tire-inflation-cage). Do not blow up the
tires with greater pressure than specified in the
following table because a blown tire can cause
serious injury.
2. Checking the tire pressure
Check the tires and rims for damage and eliminate
problems before starting operation.
If the air pressure in the tire is too high or too low, the
life of the tire will be shortened. Check the air pressure
in tires routinely.
1. Check the tire pressure.
(A) Deficient
(B) Correct
(C) Excessive (D) Ground level
• Insufficient low tire pressure
Too small amount of air in the tire can cause the
tire to obtain excessive slack, which makes for
faster wearing down of the tread.
• Excessively high tire pressure
Too high tire pressure causes the tractive force
of the machine to decrease or the tire to slip.
There is also the risk of a blow out.
2. Correct the tire pressure if necessary.
