Section 4: Maintenance - Grizzly T23102 Owner's Manual

section 4: maintenance

Follow regular maintenance to keep the
chain block in good working condition.
to avoid serious injury from failure, never
attempt to repair a chain block that mal-
functions or becomes damaged. repair
or service must be done by a qualified
technician only.
the hazard of an improper repair job is
that it could cause the chain block 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
chain block 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 chain block housing and the chains.
NOTICE
do not submerge the chain block
housing in liquid of any kind or allow
liquid to enter the brake cover dur-
ing cleaning, or the braking mecha-
nism 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 chain block, clean and
lubricate the chains. always store the
chain block in a clean, dry, and protected
area to prevent corrosion or damage.
a malfunctioning or damaged chain
block 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 the chain block
malfunctions or becomes damaged,
replace it, or have it serviced by a
qualified service technician.
