3. Ensure the preventative maintenance requirements,
on pages 12 and 13 of this manual have been met.
Inspect the wire rope and winch and repair any defects
before operating the hoist.
4. Ensure operators are trained and understand the Gen-
eral Safety Recommendations section of this manual.
5. After the hoist/boom is properly positioned, we rec-
ommend the operator slowly pay-out, then haul-in a
short length of cable. The winch should perform these
operations in a smooth and controlled manner. If the
hoist does not operate smoothly or makes any unusual
sounds, the source of the problem should be identifi ed
and corrected before any attempt is made to lift the
load.
6. When lifting loads, we recommend the following
steps:
• Slowly pay-out wire rope from the hoist drum until
it reaches the load.
• Securely fasten the hoist cable to the load and be
sure all ground personnel are a safe distance from
the load.
• Slowly lift the load a short distance and stop. A
small amount of “bounce” may be observed, depend-
ing on the weight of the load, size and type of wire
rope, and the amount of boom extension.
•
Allow the load to stabilize then watch for any signs
of downward movement of load or any cable drum
rotation. The winch static brake should hold the load
in place without allowing any downward movement.
• If the load creeps down or there is any movement
of the cable drum, the load should be lowered to the
ground immediately and the source of the problem
identifi ed and corrected.
• If the winch is holding the load securely, proceed
with normal operations in accordance with the equip-
ment manufacturer’s operating procedures.
7. The air motor should not be allowed to race when low-
ering heavy loads. Always operate within the speeds
given in the sales brochure.
