section 4: maintenance
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 malfunc-
tions 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 during
routine maintenance. the Brake Cover
should only be removed by a qualified
technician; it encloses the friction brake
and protects it from exposure to contami-
nants, such as liquids or lubrication, that
will cause the brake to fail under load.
cleaning
to prevent the chains from jamming, clean
away dirt and debris from the outside of
the hoist housing and the chains.
NOTICE
do not submerge the hoist housing
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 lubri-
cate the chains. always store the hoist in
a clean, dry, and protected area to prevent
corrosion or damage.
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.
