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.
