3. While fully depressing the pendent throttle lever and holding it in that position, turn in the
adjustment screw until the piston rod fully retracts. This adjustment will provide a good balance
of spotting control and maximum hoist speed. If better spotting control is desired, slowly back
out the adjustment screw a little at a time until the spotting control is suitable.
4. Tighten the adjustment screw locknut.
Storing the Hoist
1. Always store the hoist in a no load condition.
2. Wipe off all dirt and water.
3. Oil the load chain, hook pins and hook latch.
4. Place in a dry location.
5. Plug hoist air inlet port.
6. Before returning hoist to service follow instructions for Hoists not in Regular Service in the
"INSPECTION" section.
The four most important aspects of hoist operation are:
1. Follow all safety instructions when operating hoist.
2. Allow only people trained in safety and operation on this hoist to operate the hoist.
3. Subject each hoist to a regular inspection and maintenance procedure.
4. Be aware of the hoist capacity and weight of load at all times.
Always operate, inspect and maintain this hoist in accordance with any applicable safety codes and
regulations.
Operators must be physically competent. Operators should have no health condition which might
affect their ability to react, and they must have good hearing, vision and depth perception. The hoist
operator must be carefully instructed in his duties and must understand the operation of the hoist,
including a study of the manufacturer's literature. The operator must be aware of proper methods of
hitching loads and should have a good attitude regarding safety. It is the operator's responsibility to
refuse to operate the hoist under unsafe conditions.
Initial Operating Checks
Hoists are tested for proper operation prior to leaving the factory. Before the hoist is placed into
service the following initial operating checks should be performed.
1. After installation of trolley mounted hoists, check to ensure the hoist is centered below the
trolley.
2. Check for air leaks in the supply hose and fittings to pendant, and from pendant to manifold.
3. When first running the hoist or trolley motors, a small amount of non-detergent, light oil should
be injected into the inlet connection to allow good lubrication.
4. When first operating the hoist and trolley it is recommended that the motors be driven slowly
in both directions for a few minutes.
5. Operate the trolley along the entire length of the beam.
6. Check operation of limit devices.
7. Check that trolley (if equipped) and hook movement is the same direction as arrows or
information on the pendant control.
8. Check to see that the hoist is securely connected to the overhead crane, monorail, trolley or
supporting member.
9. Check to see that the load is securely inserted in the hook, and that the hook latch is engaged.
10. Raise and lower a light load to check operation of the hoist brake.
