101 Auxiliary Hoist Figure 6-14 H
8.5 L
(9.0 qt)
• Check and fill every
50 hours or weekly
• Drain and fill after
first 300 hours, then
every 1000 hours or
12 months
thereafter
• Check and clean
breather as needed
Oil level must be
visible in the sight
glass.
NOTE: Line up the Fill/Drain Plug with the top cutout hole (A). Verify hoist is level side to side. Place a level along the tie
rod and confirm the bubble is centered. Let hoist sit idle for 20 minutes for an accurate reading. Oil should be
visible in sight glass. Level of oil is acceptable if it is at least 1.6 mm (1/16 in) down from top or up 1.6 mm (1/16 in)
from the bottom of the sight glass. Hoist and oil temperature should be in the 21°C ± 7°C (70°F ± 20°F) range. If oil
temperature is outside this range, allow for a higher oil level reading if hotter or a lower oil level reading if colder.
Oil escaping from vent plug is an indication the hoist may be overfilled. If hoist is over filled move the Fill/Drain
Plug to the lower cutout hole (B) and drain until oil level falls within the sight glass.
