• Hoisting attachments, such as wire rope and
shackles, used in hoisting must be rated for the
total weight of this machine.
• Do not use the loops on the top of the boom to

ground before hoisting.
Lift the machine on hard and level ground and in
the following procedure:
1. Let the machine assume Travel Position as

3. Immediately after the machine is lifted off
ground, wait for the machine to be stable
before continuing to lift slowly.
4. When lifted, make sure that there is no
change in machine position due to leakage in
hydraulic circuit on the head end of derrick
cylinder (3), or there is no play at the hook
hanger (4).
