Operation

Notes for rubber crawler operation


Driving or turning on sharp objects or over steps causes
excessive wear on the rubber crawlers and will lead to
breaking of the rubber crawler or cause the crawler running
surface and the steel inserts to be cut.

Make sure that no foreign objects get stuck in the rubber
crawler. Foreign objects lead to excessive crawler wear and
can cause it to break.

Keep oil products away from the rubber crawlers.

Remove any fuel or hydraulic oil spilled on the rubber crawlers.

Making sharp turns


On streets with a high-friction tarmac, e.g. concrete, do not make sharp turns.

Protecting the crawler against salt


Do not work with the machine on the seashore. (The salt will cause the steel insert to corrode.)

Operating the controls during excavation work

Always observe the following safety instructions when working with the excavator.

Never crush concrete or boulders using side boom swings with the bucket.

Do not use the dropping action of the bucket for excavation.

Never fully extend the cylinders. Always keep a certain safety margin, especially when operating with a
breaker (accessory).

Never use the bucket as a hammer to drive posts into the ground.

Do not drive or dig with the bucket teeth rammed into the ground.

When loading soil, do not dig the bucket deeply into the ground. Instead, make relatively shallow slices
with the bucket out as far as possible. This technique reduces the stress on the bucket.

When working in water, the water should only reach up the lower edge of the swivel frame.

After using the machine in water, always grease the pins at the bucket and arm with grease until the old
lubricating grease emerges.

When digging with the boom above the dozer, make sure that the boom cylinder does not come into con-
tact with the dozer.
