Pendant Control Adjustments
The bleed adjustment screws (19) or (336 [old style]) used on
hoists with a pendant control are factory adjusted to provide
optimum control at 90 psig (6.3 bar/630 kPa) air pressure. If the
hoist is used with other air supply pressures, the bleed
adjustment screws may require readjustment.
For maximum performance and control, adjust the bleed screws
(19) or (336 [old style]) as follows:
1.
Loosen the adjustment screw locknut (21) or (337 [old
style]).
2. Turn the adjustment screw (19) or (336 [old style])
counterclockwise approximately one third (1/3) of a turn.
3. Fully depress the pendant throttle lever (165) and hold in
depressed position. Turn the adjustment screw clockwise
until the piston rod fully retracts. This adjustment will
provide a good balance of spotting control and maximum
hoist speed. If better spotting control is desired, slowly
back out the adjustment screw a little at a time until the
spotting control is suitable.
4. When adjustment is complete, hold the adjustment screw in
position and tighten the adjustment screw locknut (21) or
(337 [old style]).
5. Repeat steps 1 through 4 for opposite pendant throttle
lever.
Storing the Hoist
1. Always store the hoist in a no load condition.
2. Wipe off all dirt and water.
3. Oil the load chain, hook pins and hook latch.
4. Place in a dry location.
5. Plug hoist air inlet port.
6. Before returning hoist to service follow instructions for
‘Hoists not in Regular Service’ in the “INSPECTION”
section.
