CONTROLS
The Power Unit provides one circuit, with an oil fl ow of 7
gpm/26 lpm up to 2000 psi/140 bar.
Figure 3. Panel and Control Lever
One hydraulic tool can be connected to the tool circuit. The
circuit is activated by moving the control lever to the "ON"
position.
THROTTLE CONTROL
The Power Unit is equipped with an automatic throttle con-
trol that permits the operator to select one of 2 operating
modes—automatic throttle or manual throttle. See fi gure 4.
Figure 4. Throttle Control Knob
Automatic throttle Control
In this mode, engine speed varies with hydraulic circuit
pressure during tool use to maintain a constant 7 gpm/26
lpm. When a tool is not being used the engine will return to
idle automatically.
Automatic Throttle Control is set by positioning the adjust-
ment knob (shown in fi gure 4) to the far right and tightening
it to maintain its position.
Manual Throttle Control
In this mode, engine speed is manually held at full throttle
to maintain 7 gpm/26 lpm. When a tool is not being used
the engine
will not
return to idle until the manual setting is
removed.
Typical conditions requiring the manual throttle control are:
