Thank you for your purchase of a
Grizzly Chain Hoist. We are confident
you will find this Hoist to be extreme-
ly useful for your lifting and material
movement needs. Chain hoists are
especially useful in situations where
no power supply is available.
Whether you use it on the farm, the
construction site, the dock, the base-
ment or the garage, you will find the
mechanical advantage your Chain
Hoist provides will be a great benefit.
Chain Hoists must be used in a safe
manner, and we strongly urge you to
review the safety warnings contained
in this manual and on the product
label before using this device. When
used safely and when properly main-
tained, you can expect years of trou-
ble-free, enjoyable operation.
Refer to the table below to verify the
operating characteristics of the spe-
cific Model you purchased. The
Model number appears on the label
on the side of the gear block body. Be
sure you understand the capacity and
lift dimension requirements of your
particular unit before using it.

Safety Instructions For Chain Hoists
the safety catch is operating.
3. Periodically inspect the hook
and chain to verify that the
metal displays no cracking or
other signs of potential failure.
4. Never allow the hoist operator
or other personnel to pass
underneath a suspended load.
5. When lifting or lowering, the
hand chain should be pulled
steadily to avoid jerking or tan-
gling of the chains.
6. If the hand chain should ever
seem to require excessive
force, check for the following:
a)Is the load over the rated
capacity of the hoist?
b)Is anything entangled in the
load?
c)Are the chains blocked or
trapped on something?
Operating a Chain Hoist can be dan-
gerous if not used properly. Your
Hoist has a warning label affixed
similar to that shown below. Please
take a few moments to familiarize
yourself with the warnings it
describes.
In addition, please refer to the warn-
ings displayed on the opposite page
as well as the additional warnings
described here:
1. Never use a motor or other
mechanical device to lift the
load. The Chain Hoist is
designed to be comfortable for
a person to lift using hand
power.
2. Before lifting, inspect the hooks
to make certain they are
securely attached. Also verify

OPERATION
1. Secure the hook which is directly
attached to the gear block body to
a structurally sound overhead
beam which is capable of handling
the weight to be lifted. The hoist
can be mounted to a beam trolley
if the capacity of the trolley system
is equal to or greater than the
anticipated load.
2. Position the load directly under the
chain hoist. Connect the load hook
to the item. Positioning the hook
on the load may require lifting
straps or chains if a suitable lifting
device is not incorporated on the
load (e.g. an eye bolt). Never wrap
the hoist’s lifting chain around the
load. Always use a separate set of
straps or chains which should then
be connected to the load hook. Be
sure the load chain is not twisted
or entangled in the lifting chain.
3. Pull on the lifting chain with even
pulls until the chain between the
load and the gear block is taught.
Inspect the load chain and hook
position to make sure it will stay
properly positioned as the lifting
continues.
4. Continue pulling the lifting chain
evenly and steadily until the load is
raised.
5. Move the truck or pallet you are
placing the item on under the
raised load. If the Hoist is attached
to a travelling trolley system, move
the load slowly and carefully, mak-
ing sure that no one passes
beneath the load as it traverses.
6. When the load is positioned as
desired, pull in the opposite direc-
tion on the lifting chain until the
tension on the load chain has been
released.
7. Release the load chain.
1. Clean any dirt off of the hand and
load chains and gear block to
avoid having any foreign material
potentially interfere with the brake
and ratchet system.
2. Periodic lubrication with a light
grease on the gears inside the
chain gear block will ensure free
and smooth operation. Grease can
be applied with a scrap piece of
wood through the opening in the
bottom of the gear block.
3. Generally disassembly of the gear
block mechanism should never be
required. If it should become nec-
essary, this maintenance should
be performed by a skilled service
technician who is familiar with
these types of lifting devices.
4. If the device is disassembled for
servicing, be sure to check the
hoist with a light load to be sure
the brake mechanism is proper-
ly holding the lifted load. If it
appears okay with a light load,
move to a load at its maximum
capacity and perform the same
check
MAINTENANCE
Disassembly and improper
reassembly of this device can result
in the braking or locking mecha-
nisms not working properly. Loads
may not stay suspended and might
cause a crushing injury. Always
have this device serviced by an
qualified repair technician. Serious
injury will result.
