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.
・
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.

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.
Brake fluid
Inspect
○
Check that the brake fluid level is between the
level marks (LEVEL and MIN). If there is no
external leakage but the level has dropped, check
the disk brake pads for wear. If there is no
problem with the brake pads, add brake fluid.

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
l e a s t t w i c e a d a y, n o t j u s t d u r i n g t h e
