Attachments
Place attachments that have been removed from the machine in
a stable condition so that they do not fall.
ATTENTION
Caution – Danger of injury!
Working beneath the machine

Always lower all movable work equipment to the ground or
to the lower position before performing maintenance or
repair work under the machine.

Block the wheels with a wheel chock.

Never work under a machine that has not been sufficiently
secured.
Keeping the machine clean

Always keep the machine clean and tidy.

Oils, grease and tools or parts laying around are dangerous
because they are a potential source for slipping or tripping.

Do not use water or steam to clean sensors, plugs and the
interior of the cab. If water gets into the electrical system,
there is a hazard that it will cause malfunctions or misopera-
tion and lead to accidents.
Special operations
Always wear appropriate protective clothing and protective gog-
gles when sanding, welding, using the sledge hammer or per-
forming similar work.
