Tires
Air pressure
Inspect
○
・
Check the tire pressure with a tire gauge while
the tires are still cool before driving anywhere.
Adjust the pressure as necessary to the rated
pressure. Do not stand in front of the tire
during adjustment because the tire may burst.
・
Check that there is no damage to the sidewalls
and no cracks or abnormal wear to the treads.
Replace any tires which have exposed canvas,
regardless of their age.
・
Check whether the treads are worn to the limit
of use. Also check for metal fragments, nails,
stones and other foreign bodies stuck into the
treads or caught in the tread grooves.
・
Check the depth of the tread grooves and look
for abnormal wear. Worn tires are dangerous
as they could burst or allow skidding.
・
Replace any tires where the limit of wear
indicator is visible.
There are six points at a depth of 1.6mm
spaced around the circumference of the tire
which serve to indicate when the limit of wear
has been reached.

Foot brake
Depression distance
Inspect
○
Braking effect
Inspect
○
Test the foot brake while the machine is moving
very slowly to check that the braking force is
adequate and applied evenly.
Parking brake
Braking effect
Inspect
○
Air tank
Water
extraction
○
Maintain the air pressure in the air tank at the
rated level and pull the drain cock lever under
the air tank to drain any water that has
accumulated inside the tank. In winter, this water
can freeze and block pipes, so drain the water at
least twice a day, not just d uring the
preoperational check.
Reserve tank
Braking fluid
Inspect
○
Check that the fluid level is between the level
marks (LEVEL and MIN). If the fluid level is
lowered in spite of no external leakage, inspect
wear of the disk brake pads. If there is no
abnormality, refill the brake fluid.
Auxiliary brake action
Inspect
○
Apply the auxiliary brake while the machine is
moving very slowly to check its action and that
each relevant indicator lamp lights.
Air drier
Drain water
