• Know the load to be moved.

DO NOT

OVERLOAD!

• Do not drive without locking the slew lock.

The boom may rotate unexpectedly.

• When swinging a load, watch out for centrifugal

force. As you swing a load this force will
cause the load to swing away from the machine
and may cause instability.

• Make sure vehicle is positioned in an area

free from overhead obstructions.

KEEP A

SAFE WORKING DISTANCE!

• Do not rotate or extend a load over

anyone.

• All outrigger sections must be fully pinned

before starting recovery work to avoid
damage to outriggers and outrigger extension
cylinders.
