3.0 Preoperational Procedures
3.1 Gear Box
3.1.1 The gearbox is filled with the correct amount of oil at the time of shipment. The oil level must be verified
prior to operation. The ER2 and NER2 hoists hav e different checki ng procedu res. Refer to Sectio n 6.3
of the ER2OM for specific checking procedures. Use the 050L Capacity Co de to determine the correct
“Check Distance” for the ER2 Large Capacity hoist.
3.1.2 Refer to Section 6.3 of the ER2OM when repl acing the gear oil. Use the 050L Capa city Code to
determine the correct amount of gear oil.
3.1.3 All ER2, mechanical load brake installed, hoist s are shipped with a separate air vent ed oil cap. This
vented oil cap must be installed prior to use . To install, remove an existing oi l cap and replac e with the
vented oil cap (refer to Figure 3-1).
3.1.4 There are two oil fill holes located in the top of the gear case on the ER2 hoist. For ER2 coupled to
MR2 trolley, there are some flange widths that make it necessary to relocate the oil cap assembly to the
other oil fill hole. This will prevent interference with trolley side plate. Refer to Figure 3-1.

3.2 Chain
3.2.1 The quantity and location of the chain com ponents inclu ding chain springs and st oppers depe nds on
the hoist model and capacity. Never ope rate the hoist with in correct, missing or damaged ch ain
components. Refer to the hoist' s nameplate, Table 3-2, and Figure 3-2 and ensure that all chain
components are in the correct location and properly i nstalled.
3.2.2 When the hoist is used without a chain co ntainer, the free end of the chain is attached to the hoi st body
as shown in Figure 3-2. Connect the “no load” en d of the chain to Chai n Guide A and t he pre-install ed
socket bolt and lock nut. Make sure the chain remains free of t wists and the chain Stopper is i nstalled
on the correct link. Refer to Table 3-2 for proper placement of Stopper.

3.2.3 When the optional canvas chain container(s) i s used, unfold it fully a nd install it on the hoi st body(i es)
as shown in Figure 3-3. In this case the free en d of the chain is not att ached to the ho ist body and the

DO NOT use a chain container with a storage capacity less than the lif t length on the hoi st. If all of the
chain can not be stored in the container, the limit switch will not operate properly.

3.5.7 The following instructions apply when the hoist is hook mount ed to a fixed su spension point or install ed
on a manual trolley. The hoist is controlled by a pendant with two push butto ns – one for lifting a nd one
for lowering. Refer to the appropriate trolley Owner’ s Manual if the ho ist is installed o n a motorized
trolley. Special wiring considerations must be taken if th e trolley is used with a troll ey other than an
MR2 model.
Pendant Cord
The Pendant Cord connects to the hoist via an 8-pin (8P) Plu g and Socket. Make this con nection
as follows:
Refer to Figure 3-5 or 3-6 depending on the Product Code.
For ER2080S and ER2100L - Insert the 8P Plug into the 8P Socket on the hoi st body and
hand tighten the Lock Ring. Install the stra in relief cable to the botto m of the hoist bo dy.
For ER2100S, ER2150S and ER2200S - Insert t he 8P Plug into the 8P Socket on the switch

Power Supply Cable - Installation
If the hoist is hook mounted to a fixed support ensure that the Power Supply Cable is properly
installed and supported between the hoi st and the electri cal power sup ply.
If the hoist is installed on a manual trolley, then th e Power Supply Cable mu st be installed al ong
the beam that the trolley runs on. For curved beams a specia l cable suspension sy stem will be
needed, and this instruction does not appl y. For straight beams in stall the Power Su pply Cable as
follows:
Refer to Figure 3-7.
Install the Cable Hangers on to the Power Supply Cable spa cing them every 5 feet.
Install a Guide Wire system pa rallel to the Brid ge Beam. Pass the G uide Wire throu gh the
Cable Hangers and the Wire Guide.
Make sure the Guide Wire i s properly tensi oned and the Power S upply Cable i s not twisted o r
kinked.
3.5.8 Connection to Electrical Power Source - The red, blue, and black wires of the Power Supply Cable
should be connected to an Electric Power Disconnect Switch or Circuit Breaker. This connection
should be made so that the hoist is phased properly. Refer t o Section 3.6.11 for instructions on how to
check for correct power supply phase connection.
3.5.9 Fuse/Breaker Capacity -The hoist's power supply should be equipped with ove rcurrent protection such
as fuses, which should be selected for 110% to 120% of total listed full load am perage, and sho uld be
dual element time-delay fuses. Refer to the motor nameplate(s) for the full load amperage draw.

Verify that the controls agree with hoist direction. Make sure that depression of the up button lifts
the load chain and depression of the down butto n lowers the load chain hook. If the l oad chain
does not move in the correct direction when the push but tons are pushed, th e power supply is
phased incorrectly. In this case, turn off the power source or breaker switch

7) Install the St opper and Chain Spring to the free en d of the new chain. Refer to Se ction 3.2 in this
supplement for the correct location.
8) Disable Hoist Body B by unpluggi ng its 8P plug. Operate Hoist B ody A in the down dire ction to move
the new chain through the hoist until a sufficient qua ntity of chain has a ccumulated between th e hoist
bodies. Re-enable Hoist Body B by re-inserting its 8P plug.
9) Disable Hoist Body A by unpluggi ng its 8P plug. Operate Hoist B ody B in the up direction to move the

12) For hoist s without a chain container, attach the ends of the chain to Chain Guide A on each body wit h
the socket bolt, and lock nut (see Figure 3-2). Ensure that all ch ain parts remain f ree of twists and
correct any if found.
