2. 6 STEERING CONTROLS

The two steering levers control speed, direction, and
turning the loader. The R.H. lever controls the wheels on
the R.H. side of the loader and the L.H. lever the L.H.
wheels. Loader speed is controlled by the amount each
lever is moved from centre or neutral position. (Fig. 2 6A)

The further away from neutral the faster the travel speed.
For maximum travel speed, move the control levers full
forward or rearward for reverse. For maximum power,
move the control levers only a small amount.

To drive the loader forward in a straight line, move both
control levers forward the same amount (Fig. 2. 6B).

AUXILIARY HYDRAULICS:

The foot pedal is used to engage the loaders auxiliary hydraulic
circuit to power an attachment such as a post hole auger. (Fig.2.
8A) Pressing on the toe of the pedal provides hydraulic flow to
the female quick-connect coupling located at the front of the
boom arms. Firm pressure on the toe of the pedal will lock it
into detent position providing a continuous flow of hydraulic
oil to the attachment. Pressing on the heel of the pedal provides
hydraulic flow to the quick-connect coupling reversing the
flow of hydraulic oil. If not locked in detent position, releasing
the pedal will cause it to return to the neutral position stopping
all hydraulic flow. Once the pedal is locked in detent, it can be
returned to neutral by tapping the heel of the pedal.
