GENERAL OPERATION INFORMATION

TRAVELING
When traveling over obstacles such as boulders or tree
stumps, the machine (in particular, the undercarriage) is sub-
jected 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 traveling over them.
When the variable gauge is fully retracted, there is particular
danger of the machine tipping over to the left or right if the rub-
ber crawler on one side travels over obstacles such as boul-
ders or tree stumps or goes into a ditch or hole. In such places,
lower the travel speed and be extremely careful to maintain the
machine balance when traveling.
PERMISSIBLE WATER DEPTH
CAUTION
When driving the machine out of water, if the angle of the
machine exceeds 15º, the rear of the upper structure will
go under water, and water will be thrown up by the radia-
tor fan. This may cause the fan to break.
Be extremely careful when driving the machine out of
water.
Do not drive the machine in water deepen than of the center of
carrier roller(1).
Supply grease to the parts which have been under water for a
long time until the used grease is projected out of the bearings
(around the bucket pin, in particular).
