4.10 WATER TANK RAISE & LOWER
PROCEDURE
Raising and lowering a Ground Force Worldwide water
tank is very similar to operating a Caterpillar dump
bed, but there are some special considerations.
Please read the following instructions carefully.
NOTICE
Drain the water tank.
The water pump controls must be turned off in the
Ground Force Water Control System.
Remove the quick fill plumbing.
Enable the hoist control in the ECM.
CAUTION
The Ground Force Worldwide water tank design has different
tail clearances from a Caterpillar dump bed.
While tipping, closely observe the tank during operation
of the raise function to prevent damage to the tank or sur
-
roundings. Remove anything that might interfere with raising
the tank.
