UNPACKING

Lift the hoist out of the carton by the top hook or the centre
section. Do not apply excessive force to the motor cover, as
damage may result.
Carefully inspect the hoist for shipping damage, and for
loose or missing parts. Report any damage immediately
to your distributor and shipping agent. Do not discard
any shipping material until the Hoist is installed and
running properly.

INSTALLATION & ASSEMBLY
Support for the hoist may be hook, clevis pin, trolley, or
beam clamp. Supporting structures (such as I-beams,
etc.) should be installed by properly licensed
professional installers.
Whatever method of suspension is
chosen, the support components must be rated equal
to or greater than the capacity of the chain hoist.
Electrical Connections
Electrical connections must be made
by a qualified electrician in compliance with all relevant
codes. This machine must be properly grounded to help
prevent electrical shock and possible fatal injury.
Figure 2
This machine's power cable is installed with a plug that has
an equipment-grounding conductor and a grounding prong,
similar to that shown in Figure 2. The plug must be plugged
into a matching outlet that is properly installed and grounded
in accordance with all local codes and ordinances. Do not
modify the plug — if it will not fit the outlet, have the proper
outlet installed by a qualified electrician.

Grounding Instructions

This machine must be grounded. In the event of a
malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of
electric shock.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface that
is green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
Make sure the voltage of your power supply matches the
specifications on the nameplate of the hoist.

Extension Cords

If an extension cord is necessary, make sure the cord rating
is suitable for the amperage listed on the hoist's nameplate.
An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
Use Table 2 as a general guide in choosing the correct size
cord. If in doubt, use the next heavier gauge. The smaller
the gauge number, the heavier the cord.
