UNPACKING
After opening the carton, carefully inspect the hoist frame,
control tube, hooks and pendant throttle control for damage
that may have occurred during shipment. If there is
damage, refer to the packing slip envelope.
All hoists are completely assembled, lubricated and load
tested prior to shipment. To place the hoist in service,
attach the upper hook to a support or trolley that has
sufficient strength to support the hoist and several times
the rated capacity of the hoist. If in doubt, consult a
registered engineer and local building code.
Be certain that the upper hook is attached to the support
so that the support is firmly seated in the center of hook
bowl, the latch closes and contacts the tip of the hook, and
that the latch does not bear against the support.
AIR SUPPLY SYSTEM
Connect hoist to a filtered and lubricated air source using a
1/2” (12.7 mm.) I.D. hose (see Figure 3). Do not use
smaller diameter hose, since it will restrict air flow and
reduce hoist performance. If the hoist is suspended from a
trolley, provide sufficient hose to reach from the source to
the farthest point of trolley travel. CM
®
Hose Trolleys are
recommended to keep the hose up and out of the way.
A filter and lubricator (see Figure 3) m
mu
us
stt be installed
between the air source and the air hose leading to the hoist.
These keep the air flowing free from dirt and add lubricant
to the air so internal parts of the motor are constantly
lubricated. Use a good grade of oil with a viscosity of 180
SSU at 100
0
F., air powered tool oil or SAE 0W machine oil.
The recommended operating air pressure for the hoist is 90
psig. When line pressure exceeds 100 psig (at the hoist
when it is lifting rated load), it is recommended that a
pressure regulator be provided in the air supply line to keep
the pressure at 90 psig. Although there is a wide range of
pressures within which the hoist will operate, motor efficiency
decreases as the air pressure drops (refer to the following
Chart).
On the (500, 600 and 1000, (226, 272 and 453 Kg.), Double
Reeved units), cut and discard the ties used to hold the two
strands of chain together. With no load on the lower hook,
depress the UP ( ) lever in the pendant throttle control and
raise the lower hook until it is about 2 feet (0.61 M) below the
bottom of the hoist. Check both strands of chains for twists.
Twists occur if the lower hook block has been capsized
between the strands of chain during packing, shipment
and/or handling. Reverse the capsize to remove twists.
CHAIN CONTAINER
If the chain container is to be used, attach it to the hoist
per the instructions provided.
OPERATING INSTRUCTIONS
The hoist is equipped with a Protector™ that is designed to
allow the first gear to slip when it is attempted to lift an
excessive overload. An overload is indicated when the
hoist speed slows down, it raises the load in a jerky
manner or if it will not lift the load at all. In addition, some
clutching noise may be heard. Should this occur,
immediately release the UP ( ) lever to stop the operation
of the hoist and reduce the load to the rated capacity of
the hoist. When the excessive load is removed, normal
operation of the hoist is automatically restored.

Due to the above, the hoist is not recommended for use in
any application where there is a possibility of adding to an
already suspended load to the point of overload. This
includes dumbwaiter installations, containers that are loaded
in mid-air, etc. Also, if the hoist is used at unusual extremes
of ambient temperatures (above 150
0
F., 65
0
C., or below
15
0
F., -9
0
C.), changes in lubricant properties may permit
the hoist to raise larger loads than under operating
temperatures and could present possibility of property
damage or injury. Hoist operation is controlled by
depressing the pendant throttle control levers. Depressing
the UP ( ) lever will move the lower hook towards the hoist
and depressing the DOWN ( ) lever will move the lower
hook away from the hoist. The speed of lifting and lowering
can be varied by the distance the lever is depressed. To
stop lifting and lowering, release the lever. The up and down
levers are momentary type and the hoist will operate in the
selected direction as long as the lever is held in the
depressed direction. Release the lever and the hoist will
stop.
Operating the hoist with obvious external damage may
cause load to drop and that may result in personal injury
and/or property damage.
TO AVOID INJURY:
Carefully check hoist for external damage prior to
installation.
Suspending the hoist from an inadequate support may
allow the hoist and load to fall and cause injury and/or
property damage.
TO AVOID INJURY:
Make sure the structure has sufficient strength to hold
several times the hoist and its rated load. Using the
upper hook, hang the hoist from the support. B
