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.
