Connecting Hoist to Air Source:
1.
Connect hoist to a filtered and lubricated air source with a least 1/2” I.D (see image 2)
2. If the hoist is connected with trolley, the hose must be long enough to reach from air
source.
3.
A filter and lubricator unit must be installed between air source and air hose connected to
the hoist to assure the air hoist will receive consistent, clean air flow. (see image 3)
4. DO NOT use multi-viscosity, detergent-type engine oil. USE air hoist motor oil or 10W
machine oil (approx. viscosity 150 SSU @ 100 deg. F). The lubrication rate for air supply
should be 1 drop for every 50-75 cu. Ft. Recommended air pressure is 90 psi.
Speed Adjustments:
1.
For lifting speed, the maximum is pre-set. The lowering speed is adjusted to an average
setting between minimum and maximum.
2.
To adjust speed, turn the adjusting screw shown in image 4. The speed will be max or min
when the head slots on the adjusting screws are horizontal. Rotate screws 180 deg. In
either direction for full range of speed adjustment.
3.
NOTE the max lowering speed with rated load is very high. Adjusting screws should not
be adjusted beyond outer surface of hoist housing.
