Inspecting Hoist Motion
1. Before closing the circuit breaker and testing
the hoist, check that wiring has been complete.
If the hoist cannot be observed when the
circuit breaker is closed, station an observer
within sight of the hoist to report any
movement when power is applied to the hoist.
Be prepared to disconnect power if hoist motor
starts when the power is applied. The hoist
must remain motionless when power is
applied. Find and correct any problems before
continuing.

2. With no load on the load hook, press the UP
button very briefly and observe hoist action.
The hook should move upward.
The hook should move upward.
3. If no motion occurs when the UP button is
pressed and the hoist is connected to a three
phase power supply, the power supply wires
are incorrectly positioned. Switch any two of
the three supply wires at the power source. Do
not attempt to rewire the hoist circuit or
pendant controls for this problem. Use the
same safety precautions when reversing two
of the supply wires as was used when the
wires were originally connected.

4. Re-connect power and test hoist movement
again without load. Run hoist to the complete
lifting height to ensure limit switches are
operating properly.

Extension Cords
If an extension cord is necessary, make sure the
cord rating is suitable for the amperage listed on
the hoist's motor plate. An undersized cord will
cause a drop in line voltage resulting in loss of
power and overheating.

The chart in Figure 6 shows the correct size cord to
use based on cord length and motor plate amp
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

Installing Chain Container
Your hoist is supplied with a canvas chain
container (Figure 7) designed to fit the particular
length of chain. If a different length chain is ever
installed on this hoist, the chain container must be
replaced by one of proper size. See chart on page
19.

installed on this hoist, the chain container must be
replaced by one of proper size. See chart on page

Do not overfill chain container.
If chain should overfill and begin to fall, the
entire chain container may empty without
warning, resulting in serious personal injury or
property damage.

To assemble the chain container to the hoist:
1. Hang hoist in position on the I-Beam or trolley.
Do not install chain container yet. Allow slack
side and load side of chain to hang freely from
hoist.

2. Apply power to the hoist and press the DOWN
button until the lower limit switch is tripped.
3. Check the chain container to ensure that the
seam is inside the bag. The bag must not be
inside out.

4. Insert bracket prongs into interior bag slots
(Figure 7) as far as they will go.

5. Push the bracket down into the bag, making
sure the flaps are raised (Figure 8).
6. Push the flaps over and down until they are
secure (Figure 9).
