12.12 PRECAUTIONS FOR OPERATION
PRECAUTIONS WHEN TRAVELLING
When travelling over obstacles such as boulders or tree stumps, the
machine (in particular, the undercarriage) is subjected to a large shock,
so reduce the travel speed and travel over the obstacle at the center of
the tracks. As far as possible, remove such obstacles or avoid travelling
over them.
PRECAUTIONS AT Hi-SPEED TRAVEL
On uneven roadbeds such as rock beds or uneven roads with large
locks, travel at Mi or Lo speed. When Hi-speed travelling, set the idler in
the forward direction.
PERMISSIBLE WATER DEPTH
NOTICE
When driving the machine out of water, if the angle of the ma-
o
chine exceeds 15 , the rear of upper structure will go under water,
and water will be thrown up by the radiator fan. This may cause the
fan to break.
Be extremely careful when driving the machine out of water.
Do not immerse the machine in water by more than the permissible
depth (under center of carrier roller
In addition, for parts that have been immersed in water for a long
time, pump in grease until the old grease comes out from the bearings.
