Provides for remote motor control at distances up to 50* feet (15
metres) away from motor. Pilot air hoses connect pendant to motor
pilot air valve to provide motor operation. Pendant control is a two
lever movable control station which controls motor forward and

Direction of operation is determined by the pendant lever
depressed. Air is directed from pendant into pilot valve. The pilot
valve spool shifts to direct control air into motor to operate in
desired direction. Pendant handle has two arrows (cast into body),
one points up the other down. Up arrow is used for
counterclockwise motor rotation (refer to drawing MHP2016 on

To operate in the reverse direction, depress the ‘RIGHT’
lever.
2. To operate in the forward direction, depress the ‘LEFT’ lever.
3. To throttle operating speed regulate the amount lever is
depressed. Depress lever completely for maximum speed;
depress lever partially for slower speeds.
4. To stop motor operation release lever. Lever will spring
return to off and motor will stop.
• Pendant forward and reverse levers provide variable speed
operation. For low speed operation push appropriate lever
slightly; for full speed operation push appropriate lever fully.
