Improper operation of a hoist can create a potentially hazardous
situation which, if not avoided, could result in minor or moderate
injury, or property damage. To avoid such a potentially hazardous
situation THE OPERATOR SHALL:
• Maintain a firm footing or be otherwise secured
when operating the hoist.
• Check brake function by tensioning the hoist prior
to each lift operation.
• Use hook latches. Latches are to retain slings,
chains, etc. under slack conditions only.
• Make sure the hook latches are closed and not
supporting any parts of the load.
• Make sure the load is free to move and will clear all
obstructions.
• Avoid swinging the load or hook.
• Make sure hook travel is in the same direction as
shown on controls.
• Inspect the hoist regularly, replace damaged or
worn parts, and keep appropriate records of
maintenance.
• Use the hoist manufacturer’s recommended parts
when repairing the unit.
• Lubricate load chain per hoist manufacturer’s
recommendations.
• NOT use limit switches as routine operating stops.
They are emergency devices only.
• NOT allow your attention to be diverted from
operating the hoist.
• NOT allow the hoist to be subjected to sharp
contact with other hoists, structures, or objects
through misuse.
• NOT adjust or repair the hoist unless qualified to
perform such adjustments or repairs.
