The oil in the gearbox should be changed annually,
or more frequently under severe service, as
follows.
Use either of these recommended oil brands:
Mobilgear XMP 100
Shell Omala S2 G 100
Capacities:
1/4T,1/2T,1T Hoists – 0.8 Liters (0.21 gal)
2T,3T,5T,10T Hoists – 1.5 Liters (0.4 gal)
To drain and refill gearbox (refer to Figure 5):
1. Open vent plug on top of hoist.
28. Open drain plug and drain reservoir. Reinstall
drain plug.
29. Pour oil into fill hole.
30. Check level by removing side plug.
31. Reinstall top and side plugs.
10.2.2 Chain lubrication
Periodically apply a light coat of 30W oil to the
chain. This will create easier operation and prolong
the chain’s life. For optimum results, clean chain
with an acid-free solution before oiling.
10.3 Chain container
Your hoist is supplied with a chain container
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.
The chain container should be installed after the
power supply is connected to hoist. Refer to
section 11.0, then proceed with the below
instructions on chain container installation.
Do not overfill chain container.
If chain should overfill and begin to fall, entire
chain container may empty without warning,
resulting in serious personal injury or property
damage.
To assemble chain container to 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 hoist and press DOWN button
until limit switch is tripped.
3. Mount chain container to hoist undercarriage,
using a short and a long bolt with lock nuts
See Figure 6.
4. Place chain stop into container, and operate
hoist to bring load hook up until upper limit
switch is tripped.
5. Inspect chain to ensure that all non-loaded
chain is completely in container.
Do not dump chain by hand
into the chain container! By not following the
above steps, the chain can become twisted or
kinked and can damage the hoist.

11.0 Electrical instructions
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.
The 460V hoists are 3-phase only.
The 230V hoists are prewired for 3-phase, but
can be operated on either single or 3-phase power
supply. (The inverter will convert incoming single-
phase power for proper delivery to the 3-phase
induction motor.)
If an electrical plug (not provided) is installed on
the hoist power cable, it must be appropriate for
the phase used.
The hoist should be connected to a circuit with
current overload protection, rated at 120% of the
full load amperage listed on the hoist’s nameplate.
If fuses are used, they must be time-delay fuses
rated “D”. Local codes take precedence over
recommendations.
11.1 Grounding
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.
This hoist is not supplied with a power plug. Power
supply cables may either be fitted with a UL/CSA-
listed plug rated for the appropriate phase and
voltage, or “hard-wired” directly to a control panel.
If hard-wired, make sure a disconnect is available
for the operator.
If a plug is installed, it must have an equipment-
grounding conductor and a grounding prong. The
plug must be plugged into a matching outlet that is
properly installed and grounded in accordance with
