Lubrication - The hoist requires lubrication for proper operation. The oil in the air
Air Quality - Good air quality is essential to prevent damage to your hoist and to
3.2 Air Supply Capacity And Regulation
3.2.1 Capacity - The air supply system must be capable of delivering the required airflow (cfm) to the hoist
inlet port. Without the required airflow the hoist will not operate properly or may not operate at all. See
Section 2.0 for your hoists air consumption requirements. In determining if your system is capable of
supplying the required airflow, consider the following:
Capacity of compressor(s) and tank
Other air consuming equipment
Flow restrictions such as pipes, hoses, valves and fittings
Inadequate capacity will cause a significant drop in pressure when the hoist is operated, and could
cause poor performance or failure to operate.
3.2.2 Regulation - The hoist requires a constant supply of air at a pressure of between 60 and 90 psi. If the
air supply is not regulated or is regulated at a pressure greater than 90 psi, then a regulator must be
used. The regulator may be located anywhere upline of the lubricator in the air supply to the hoist.
3.3 Lubrication
3.3.1
as follows:
1) Best location - At the hoist inlet. In this case the lubricator can be either the mist type or drop
type.
2) Second best location - No more than 15 feet away from the hoist, at the same elevation or above
the hoist inlet. In this case the mist type lubricator must be used.
3) Third best location - No more than 15 feet away below the hoist. In this case the mist type
lubricator must be used.

• Maintain a firm footing or be otherwise secured
when operating the hoist.
• Check brake funct ion by tensioning the hoist prior
to each lift operation.
• Use hook latches. Latches are to retain slings,
chains, etc. under slack conditions only.
• Make sure the hook latches are closed and not
supporting any parts of the load.
• Make sure the load is free to move and will clear all
obstructions.
• Avoid swinging the load or hook.
• Make sure hook travel is in the same direc tion as
shown on controls.
• Inspect the hoist regularly, replace damaged or
worn parts, and keep appropriate records of
maintenance.
4.3 Hoist Controls
4.3.1 For hoists mounted to motorized trolleys follow the control instruction included in the trolley’s Owner’s
Manual.
• Use the hoist manufacturer’s recommended parts
when repairing the unit.
• Lubricate load chain per hoist manufacturer’s
recommendations.
• NOT use the hoist load limiting or warning device to
measure load.
• NOT use limit lever as a routine operating stop. It
is an emergency device only.
• NOT allow your attention to be diverted from
operating the hoist.
• NOT allow the hoist to be subjected to sharp
contact with other hoists, structures, or objects
through misuse.
• NOT adjust or repair the hoist unless qualified to
perform such adjustments or repairs.
4.3.2 Pendant Control - When using the pendant control depress the up lever to raise the hoist or the down
lever to lower the hoist as shown in Figure 4-1 below. To stop motion release the lever switches.
Figure 4-1Pendant Control
23
Page 24
4.3.3 Cord Control - When using a hoist with cord control, pull down on the appropriate colored cord to raise
or lower the hoist. White indicates the raise control and red indicates lowering control. Release the
cords to stop the hoist. Refer to Figure 4-2 below.
4.3.4
4.4 Adjusting the Controls
4.4.1 For pendant control, the speed can be adjusted by the amount the lever is depressed. As shown below
in Figure 4-3, by depressing the lever slightly, you will be able control the hoist’s motions slowly and
with more precision. By depressing the lever further, the speed of the hoist will be increased until the
lever is fully depressed. Refer to Figure 4-3.
4.4.2 For the cord type control, adjust the speed by varying the amount of pull on the cord. Refer to Figure
4-4.
Figure 4-3Cord and Pendant Control Speed Adjustment
Figure 4-2Cord Control
Make sure the motor completely stops before reversing direction.
24
Page 25
4.5 Speed Adjustment Controls
4.5.1 The hoist is equipped with speed adjustment controls. The controls allow the hoist lifting and lowering
speeds to be reduced for those applications requiring slower speeds or better speed control. The
speed adjustment controls are set for the highest speed from the factory. The speed adjustment
controls are located on top of the valve section of the hoist as shown in Figure 4-4.
4.5.2
4.5.3 To reduce the lifting/lowering speeds remove the speed adjustment covers to gain access to the speed
adjustment screws as shown in Figure 4-4. The covers may be plastic or aluminum. Viewed from the
valve side of the hoist, the lowering adjustment screw is on the left and the lifting adjustment screw is
on the right. The lifting and lowering adjustment mechanisms are not connected, allowing separate
adjustments for lifting and lowering speeds.
4.5.4 Referring to Figure 4-4 the hoist is at the highest speed when the screw is in the “vertical” position and
at the lowest speed when in the “horizontal” position. Speed adjustment can be made between these
postions.
The hoist must be stopped when adjusting the lifting and lowering speeds.
Figure 4-4Speed Adjustment
25
Page 26
4.6 Pendant Controllability Adjustment
4.6.1 The standard pendant hose length is 8.1 feet. For longer pendant hose lengths the speed
controllability from the pendant may be diminished. The reduction in speed control is a result of
pressure loss due to the longer pendant hose. The pendant hose extension adjustment control
provides a screw adjustment method to reduce the air pressure loss to provide normal pendant/hoist
operation. The adjustment screw is set fully open from the factory for normal operation and to allow the
fine feathering feature.
4.6.2 To adjust the pendant air pressure locate the hex nut and hex screw as shown in Figure 4-5. The
adjustment screw on the left is for adjusting the lowering speed and the adjustment screw on the right is
for adjusting the lifting speed.
4.6.3 Adjustment is accomplished by loosening the hex nut with a 2.5mm wrench and turning the hex head
screw clockwise. Once correct operation is obtained securely tighten the hex nut.
4.6.4
If the adjustment screw is tighened too tight the fine feathering feature will be
reduced or lost.
