Oil must be visible in
sight glass and level no
more than 3 mm
(0.13 in) from top of
sight glass.
NOTE: Line up Fill/Drain Plug with upper access hole (A). Let hoist sit idle for 20 minutes for an accurate reading. If oil
level is not visible in sight glass, hoist is under filled. Oil escaping from vent plug (B) or more than 3 mm (0.13 in)
from top of sight glass is an indication hoist is overfilled. If hoist is over filled, drain oil from the Fill/Drain Plug at the
upper access hole. When replacing oil, align Fill/Drain Plug with lower access hole (C) and drain oil.
Failure to align Fill/Drain Plug with upper access hole before checking oil level will result in an inaccurate reading.
