MAINTENANCE AND INSPECTION OF CARRIER
■ Adjustment
Pressurized grease is filled in the adjusting cylinder.
Do not unfasten the plug by more than 1(one) turn because slackening of
the plug too further or too quick allows the plug to pop out or the grease
to spurt out which may invite an accident resulting in injury or death. Do
not unfasten the grease nipple at this time.

WARNING
1
Inject the grease into the grease nipple
from the lubrication hole on the truck
frame and extend the grease cylinder.
2
Move the crawler back and forth to
check the rubber crawler for proper ten-
sion.
3
Check the tension of rubber crawler
again and adjust it if the proper tension
has not been obtained.
4
If the tension is too loose even after the
grease has been injected, it is neces-
sary to replace the rubber crawler or the seal
in the adjustment cylinder.
Ask UNIC or a UNIC authorized service shop
for repair.
