2...CONTROLS
When the auxiliary circuit is not in use and before starting the
loader, ensure the switch located in the. instrument panel is in
the off position, otherwise starting the loader may be difficult
or impossible and damage to the starter may occur. If for any
reason the loader stops or loses current when the electric
solenoid is engaged, it can be disengaged by simply turning off
the switch located in the upper panel, or by depressing the
poppet located at either end of the control valve (Fig. 2.9B).
2.10 FOOT PEDALS
Operation of the lift cylinders, bucket tilt cylinders and
auxiliary hydraulic circuit are controlled by foot pedals
(Fig. 2. 10) 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. 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.
Auxiliary Hydraulics –
The center pedal is used to engage
the auxiliary hydraulic circuit to power an attachment such as
a backhoe. Pressing on the toe (3) of the pedal provides
hydraulic pressure to the female quick - connect coupling
located at the front of the lift arms. Firm pressure on the toe (3)
of the pedal places the valve in detent position providing a
continuous flow of hydraulic oil to the attachment. Pressing on
the heel of the pedal (4) provides hydraulic pressure to the male
quick-connect coupling reversing the flow of hydraulic oil.
When the auxiliary circuit is not in use return the foot pedal to
neutral position otherwise starting the loader may be difficult
or impossible and damage to the starter may occur.
Bucket Tilt –
The R.H. pedal is the bucket tilt (dump)
control. Pressing on the toe (5) of the pedal will dump the
bucket. Pressing on the heel (6) of the pedal will roll the bucket
back.
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.
WARNING
Return auxiliary
hydraulic foot pedal to
neutral position when not
in use.
