2. CONTROLS
OPERATING MODES (See Fig. 2.4C):
A/0 - Trencher Operation, New Operators
This mode is used for operating motorized
hydraulic attachments such as trenchers, sweepers,
augers, snow blowers etc. This position provides a
slow travel speed as well as reduced oil flow to the
loaders boom and bucket and the cylinder spool
auxiliary hydraulic circuit while providing
increased oil flow to the motor spool auxiliary
hydraulic circuit. With the attachment connected to
the loaders motor spool auxiliary hydraulic circuit,
set the controls as follows.
Pump Selector Switch - Set switch to "A" position.
Combiner Switch - Set the switch to "0" position.
Flow Control Knob - Turn clockwise to reduce the
loaders drive speed and increase the amount of flow
to the motor spool auxiliary circuit.
With the flow control knob turned fully out (counter
clockwise), approximately 3 gpm (11.4 l/m) flows
to the loaders drive and 8.5 gpm (32.2 l/m) flows
to the motor spool auxiliary hydraulic circuit. This
provides a travel speed of 1.3 mph (2.1 km/hr).
With the flow control knob turned fully in
(clockwise) approximately 1 gpm (3.8 l/m) flows to
the loaders drive system and 10.5 gpm (39.8 l/m)
flows to the motor spool auxiliary hydraulic circuit.
This provides a travel or "inching" speed of 0.3
mph (0.5 km/hr). NOTE: While this is the
recommended trenching mode, trenching can be
performed in any mode by using the flow control
knob to divert oil.
B/0 - Bucket Operation
This mode is used for normal bucket and travel
operation as well as for operating cylinder equipped
hydraulic attachments such as grapples. This
position provides a fast travel speed as well as
quick boom and bucket operation and a higher flow
to the loaders cylinder spool auxiliary hydraulic
circuit. Attach the hydraulic powered attachment to
the cylinder spool auxiliary hydraulic circuit or
mount a bucket or other attachment and set the
controls as follows.
Pump Selector Switch - Set switch to "B" position.
Combiner Switch - Set the switch to "0" position.
Flow Control Knob - Turn clockwise to reduce the
loaders drive speed and increase the amount of oil
flow to the motor spool auxiliary circuit.
With the flow control knob turned fully out (counter
clockwise), approximately 8.5 gpm (32.2 l/m)
