14. Be sure at least five wraps of rope are left on the hoist drum to insure against rope
pulling out of its anchor.
15. Never wrap the hoist rope around a load. Always use approved rigging.
16. Avoid pinch points such as between a
rotating turret and the cab or operator
guard or in access holes of a telescop-
ing boom.
17. Avoid two blocking.
a. Stop raising hoist line before downhaul or hook block strikes boom tip plates.
b. Pay out hoist line while extending boom.
c. Maintain clearance between downhaul weight or hook block and boom tip
while booming down.

Two blocking will abruptly stop boom lowering and boom swing as well as hoist
and extend. If the boom is moving fast, this will cause the load to bounce or swing
which could cause loss of control of load or tipping.
18. The amount of counterweight supplied with this crane should never be changed.
Unauthorized addition of counterweight in the field to increase lifting ability
constitutes a safety hazard.
19. Always keep crane boom at least 10 feet (3m) away from electric power lines. (See
chart on side of turntable for boom clearance).
20. If boom should accidentally contact a power line, keep ground personnel away from
crane. Stay in the crane until the power source is de-energized. Move the crane
away from electrical hazard if this does not cause new hazards. If it is absolutely
necessary to leave the crane, jump clear of the crane with both feet together. Hop
away from the crane with feet together. The ground surface may be energized.
