2.10 FOOT CONTROLS
Operation of the lift cylinders and the bucket tilt cylinders
are controlled by the foot pedals (fig. 2.10) connected to a
hydraulic control valve. The hydraulic control valve is a
series type valve which allows simultaneoous use of both
the lift and bucket tilt circuits.
Lift –
The L.H. pedal is the lift control (Fig. 2.10). 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 previous section for
instructions on steering controls.
LIFT ARM AND BUCKET CONTROLS
The right hand lever controls the bucket tilt cylinders
(2.11). 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. 2.11) 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 cylinder to retract, lowering the lift arms. Moving the
control lever to the extreme right will place the lift arms in
the 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.
2. CONTROLS
To prevent personal
injury do not operate the
loader without lowering
the safety bar, fastening
the seat belt and keeping
feet on the control pedals
or the cab floor.
WARNING
To avoid personal injury,
lower the lift arms, shut
off the engine, raise the
seat bar and cycle the
hydraulics to ensure they
are locked. Then unlatch
the seat belt and exit the
loader. Do not enter or
exit with the engine
running unless as
specified in this manual
or under specific service
and backhoe operating
procedures.
