92 Main Hoist
93a Auxiliary Hoist
NOTE: Line up the Fill/Drain Plug with the upper access hole (A). Let hoist sit idle for 20 minutes for an accurate reading.
If oil level is not visible in sight glass, the hoist is underfilled. Oil escaping from vent plug (B) or is more than 3 mm
(0.13 in) from the top of the sight glass is an indication the hoist is overfilled. If hoist is over filled drain the oil from
the Fill/Drain Plug at the upper access hole. When replacing the oil, align the Fill/Drain Plug with the lower access
hole (C) and drain the oil.
Failure to align the Fill/Drain Plug with the upper access hole prior to checking the oil level will result in an
inaccurate reading.
