NOTE: The function speeds can also be controlled by
engine RPM. The slower the RPM the slower the
function speed.
Boom Swing Operation
Before rotating the mast, be sure there is enough clearance
on all sides and that all persons are away from the area. A
pinch point between the operator’s cab and mast can cause
injury or death.
To Rotate the Mast to the Left (Counterclockwise)
Press the accelerator pedal to increase the engine speed to
maximum RPM. Slowly pull back on the swing control lever
(Figure 3-32) until the desired swing speed is obtained. The
further the control is pulled back the faster the mast will
rotate.
To Stop Rotation
Slowly move the control lever to the neutral position and
decrease the engine speed to idle.
To Rotate the Mast to the Right (Clockwise)
Press the accelerator pedal to increase the engine speed to
maximum RPM. Slowly push forward on the swing control
lever (Figure 3-32) until the desired swing speed is obtained.
The further the control is pushed forward the faster the mast
will rotate.
CAUTION
Never put side loads on the boom. Side loads can
damage the swing gearbox. Move the boom so that it is
directly above the load before lifting the load.
