FOOT CONTROLS
Operation of the lift cylinders and bucket tilt cylinders are
controlled by foot pedals (Fig. 2.10A) connected to a
hydraulic control valve. The hydraulic control valve is a
series type valve which allows simultaneous use of both
the lift and bucket tilt circuits.
Lift –
The L.H. pedal is the lift control (Fig. 2.10A). To
raise the lift arms press on the heel (2) of the pedal. To
lower the lift arms press on the toe (1) of the pedal. Firm
pressure on the toe (1) of the pedal will lock the lift arms
in float position. This allows the bucket to follow the
ground as the loader moves backward.
Bucket Tilt –
The R.H. pedal is the bucket tilt (dump)
control. Pressing on the toe (3) of the pedal will dump the
bucket. Pressing on the heel (4) of the pedal will roll the
bucket back.
2. 11 HAND CONTROLS
Hand controls to operate the loader’s lift arm and bucket
hydraulic system as well as the loader’s travel speed and
direction are available. Refer to Section 2.8 for instruction
on steering controls.
LIFT ARM AND BUCKET CONTROLS
The right hand lever controls the bucket tilt cylinders (Fig.
2.11A). Moving the control lever to the right causes the
bucket to dump. Moving the lever to the left rolls the
bucket to the carry position.
Moving the left hand control lever (Fig. 2.11A) to the left
will cause the lift cylinders to extend, raising the loader’s
lift arms. Moving the control lever to the right causes the
lift cylinders to retract, lowering the lift arms. Moving the
control lever to extreme right will place the lift arms in
float position. This allows the bucket to follow the contour
of the ground as the loader moves backward.
When the control levers are released they will
automatically return to the neutral position stopping all
hydraulic movement and travel speed. Before exiting the
loader, lower the lift arms completely down to the frame
and ground the attachment. Then shut off the engine. Move
both levers to the left and right to ensure the hydraulic
controls are locked before you get out of the loader.
Return the auxiliary
hydraulic control to the
neutral position when not
in use.
IMPORTANT
2. CONTROLS

exit with the engine running
unless as specified in this
manual or under specific
