Cleaning

To prevent the chains from jamming,
clean away dirt and debris from the
outside of the hoist housing and the
chains.
Follow regular maintenance to keep
the hoist in good working condition. To
avoid serious injury from hoist failure,
never attempt to repair a hoist that
malfunctions or becomes damaged. Hoist
repair or service must be done by a
qualified technician only.
The hazard of an improper repair job
is that it could cause the hoist to fail
and unexpectedly drop the load, which
could crush or kill people below, or
cause major property damage. For this
reason, we strongly recommend replacing
the hoist if it malfunctions or becomes
damaged.
To avoid contaminating the friction brake
during maintenance, you must know the
difference between the gear cover and
the brake cover (see Figure 1).
The Gear Cover will be removed durin g
routine maintenance. The Brake Cover
should only be removed by a qualified
technician; it encloses the friction
brake and protects it from exposure
to contaminants, such as liquids or
lubrication, that will cause the brake to
fail under load.
A malfunctioning or damaged hoist
may drop its load and crush or
kill people below, or cause major
property damage. To reduce this risk,
observe all care and maintenance
noted in the manual. If hoist
malfunctions or becomes damaged,
replace it, or have it serviced by a
qualified service technician.
NOTIC E
DO NOT submerge the hoist housin g
in liquid of any kind or allow liquid
to enter the brake cover during
cleaning, or the braking mechanism
may fail to work properly.

Chain Lubrication

When the chains are clean and dry, apply
a thin coat of light machine oil to the
links with an oiled shop rag to ensure
smooth movement and prevent corrosion.

Storage

Before storing the hoist, clean and
lubricate the chains. Always store the
hoist in a clean, dry, and protected area
to prevent corrosion or damage.
