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 have different checking procedures. Refer to Section 6.3 of the ER2OM for specific checking procedures. Use the 050L Capacity Code to determine the correct “Check Distance” for the ER2 Large Capacity hoist. 3.1.2 Refer to Section 6.3 of the ER2OM when replacing the gear oil.
3.2 Chain 3.2.1 The quantity and location of the chain components including chain springs and stoppers depends on the hoist model and capacity. Never operate the hoist with incorrect, missing or damaged chain 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 installed. 3.2.2 When the hoist is used without a chain container, the free end of the chain is attached to the hoist body as shown in Figure 3-2.
(N)ER2100S to (N)ER2200L (N)ER2080S to (N)ER2100L Figure 3-3 Installation of Chain Container 3.2.5 When using an optional steel chain container, refer to the instructions and/or assembly drawing(s) provided with the container for correct assembly and attachment. 3.2.6 Verify that the load chain is not twisted or tangled prior to operating the hoist. Make sure the bottom hook is not capsized. See Figure 3-4. Correct all chain irregularities before conducting the first hoist operation. 3.2.
3.4.4 3.4.5 3.5 Lug Mounted ER2080S and ER2100L-LG – To maintain proper balance when the hoist is not loaded, it is necessary to install a stabilizing shaft to prevent the hoist from pivoting on the main support shaft. Refer to Figure 2-1 and Figure 2-2 for the size and location of the main support and stablizing holes in the hoist’s top suspension plates. Ensure that the fixed suspension point rests on the center of the hook’s saddle and that the hook’s latch is engaged.
Power Supply Cable - Hoist Connection The Power Supply Cable connects to the hoist via a 4-pin (4P) plug and socket or a direct fitting depending on the product code. Make this connection as follows: Refer to Figure 3-5 or 3-6 depending on the product code. For ER2080S and ER2100L insert the 4P plug of the Power Supply Cable into the 4P Socket on the hoist and hand tighten the Lock Ring.
Figure 3-6 Pendant and Power Supply Cable Connections for ER2100S, ER2150S and ER2200S Figure 3-7 Power Supply Cable Festooning and Guide Wire Location 12
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 hoist and the electrical power supply. If the hoist is installed on a manual trolley, then the Power Supply Cable must be installed along the beam that the trolley runs on. For curved beams a special cable suspension system will be needed, and this instruction does not apply.
3.6 Preoperational Checks and Trial Operation 3.6.1 3.6.2 Refer to the hoist’s nameplate and record the hoist's Code, Lot and Serial Number in the space provided on the cover of this manual. Confirm the adequacy of the rated capacity for all slings, chains, wire ropes and all other lifting attachments before use. Inspect all load suspension members for damage prior to use and replace or repair all damaged parts. 3.6.

6.4 Load Chain 6.4.1 6.4.2 1) 2) 3) Lubrication and Cleaning – refer to Section 6.2 of ER2OM. Load Chain Replacement for ER2080S and ER2100L: The hoist must be properly powered and operational in order to perform the following procedures. Be certain that the replacement chain is obtained from Harrington and is the exact size, grade and construction as the original chain. The new load chain must have an odd number of links so that both its end links have the same orientation.

Be certain that the replacement chain is obtained from Harrington and is the exact size, grade and construction as the original chain. The new load chain must have an odd number of links so that both its end links have the same orientation.
11) Remove the remaining Stopper and Chain Spring from the old chain. Inspect and replace any damaged or worn parts. Install the Stopper and Chain Spring to the end of the new chain. Refer to Section 3.2 in this supplement for correct location. 12) For hoists without a chain container, attach the ends of the chain to Chain Guide A on each body with the socket bolt, and lock nut (see Figure 3-2). Ensure that all chain parts remain free of twists and correct any if found.
