I Conformance Clarificat ion Sta t ement
1.1 Food Grade Options
Harrington ER2 Food Grade hoists are designed for applications which require food grade hoists. All
products should be tested for suitability on a particular application prior to actual use. The
occupational Safety and Health Act of 1970 places the burden of compliance with t he
owner/employer, not the manufacturer. Many OSHA requirements are not concerned or connected
with the manufactured product but are associated with the final installation. It is the owner’s
and user’s responsibility to determine the suitability of a product for any particular use. It is
recommended that all applicable industry, trade association, federal, state and local regulations be
checked. Read all operating instructions and warnings before operation.

6.2 Lubrication – Load Chain, Hooks, and Suspension
6.2.1 Load Chain
• For longer life, the load chain should be lubricated.
• The load chain lubrication should be accomplished after cleaning the load chain with an acid
free cleaning solution.
• Apply only Harrington Hoist, Inc. food grade lubricant (Part No. 2AFG003S1951) to the bearing
surfaces of the load chain links as indicated by the shaded areas in Figure 6-2. Also apply the
lubricant to the areas of the load chain (shaded areas in Figure 6-2) that contact the load
sheave. Ensure that the lubricant is applied to the contact areas in the load sheave pockets.
Figure 6-2 Chain Grease Application
• The load chain should be lubricated every 3 months (more frequently for heavier usage or
severe conditions).
6.2.2 Hooks and Suspension Components
• Hooks – Bearings should be cleaned and lubricated at least once per year for normal usage.
Use only Nevastane HT/AW 2 White Drum food grade lubricating grease. Clean and lubricate
more frequently for heavier usage or severe conditions.
• Suspension Pins – Lubricate at least twice per year for normal usage; more frequently for
heavier usage or severe conditions.
6.3 Lubrication - Gearbox
6.3.2 DETERMINING OIL LIFE - Refer to Section 6.1.3 in the ER2OM when estimating gear oil life
based on operations.
6.3.3 NER2 OIL LEVEL – The oil level is checked by removing the oil plug on the side of the hoist as
shown in Figure 6-3 for NER2 hoists. The oil level should be just below the hole when the hoist is
level.
NER2 Hoists
Figure 6-3 Oil Plug Locations

Figure 6-4
6.3.5 REPLACING OIL – Change gear oil at least once every 5 years. The oil should be
changed more frequently depending on the hoist's usage and operating environment. Refer to
Section 6.1.3. Follow the procedure below for replacing the gearbox oil for your hoist:
• To drain the current oil from the hoist remove “Oil Plug” on top of the hoist and the “Oil
Drain plug” on the bottom of the hoist. Allow the old oil to drain completely. Refer to
Figure 6-4 for oil plug locations.
•
Dispose of the used oil in accordance with local reg ulatio ns .
Oil Filling Diagram
• Ensure that the oil plugs for the oil level check holes and the drain hole are reinstalled
and secured into the hoist body.
• Refill the gear case with the correct quantity and type of new oil or until the oil level is
within the range shown in Table 6-6. Refer to Figure 6-4.

6.5 Load Chain
6.5.2 After chaining a unit, be s ure to clean any exp osed portions of bottom yoke bolts that have been
treated with thread locking compound. Conduct a thorough inspection of these bolts after
torquing to ensure there is no ex cess thread lock ing compound on t he expos ed portions. Failure
to do so could affect the hoist’s compliance with the application’s food grade requirements.

per year for normal usage. Clean and lubricate the reduction gear assembly more frequently for
heavier usage or severe conditions. Gain access to the gears by removing the four bolts that
mount the motor assembly to the trolley Side Plate. Make sure to properly orient and reuse the
neoprene gasket between the motor and Side Plate.
