At times it may be neccessary to reset the controller. This 
could happen if a fault occurs in the controller. For ex-
ample, excessive engine speed. If a fault does occur the 
power unit will return to an idle and the operator will have 
no control of the unit. To reset the controller, simply turn off 
the power unit and restart it.
USING THE 110 VOLT AC OUTLET
The 110 volt AC outlet is only found on specifi c models with 
the Briggs & Stratton engine.
The POWELINK™ system output remains 110 volts 
throughout the entire engine speed range. Output wattage 
increases with engine speed.
To use the 110 volt AC feature, turn the AC control switch to 
the ON position. The 110 volt outlet can also be used while 
in the 8 gpm mode, but is disabled when the fl ow control 
switch is set to the 5 gpm mode.
See included POWERLINK™ On-Board Generator System 
Manual for details.
USING THE 12 VOLT DC OUTLET
A 12 VDC outlet is on specifi c models. The DC outlet is ON 
at all times.
STARTUP
Before starting the engine make sure the fl ow selector 
switch is in the OFF position. 
Note: 
The power unit will not start if the fl ow control switch is 
not in the "OFF" position. 
Pull choke knob out and move the Throttle Control Switch 
to the auto-idle-off or the auto-idle-on position, whichever 
mode of operation the operator prefers. Ensure the fl ow 
selector switch is in the OFF position.
On power units equipped with the POWERLINK™ feature, 
CONTROLS
This unit is equipped with an advanced proportional engine 
control system. It provides a means of controlling engine 
speed by adjusting the fuel control lever with an actuator. 
The Power Unit provides one circuit, with an oil fl ow of 5 
gpm/19 lpm up to 2000 psi/140 bar or 8 gpm/30 lpm up 
to 2000 psi/140 bar with a factory-programmed electronic 
governed engine throttle.
Figure 3. Panel Control Valve
One hydraulic tool can be connected to the tool circuit. 
The circuit is activated by turning the fl ow control switch to 
either the 5 gpm/19 lpm or 8 gpm/30 lpm setting.
THROTTLE CONTROL
The throttle control permits the operator to select one of 2 
operating modes after the engine has warmed up. When 
starting the engine, make sure the fl ow selector switch is in 
the OFF position. The throttle control switch can be set in 
either the AUTO-IDLE-ON or AUTO-IDLE-OFF positions.
AUTO-ON
When the throttle control switch is in the "AUTO-ON" posi-
tion, the oil fl ow is regulated automatically when the trigger 
on the tool activated. When the tool is not being used the 
engine will return to idle automatically, after a 10 second 
delay.
 
This setting will produce 5 gpm/19 lpm or 8 gpm/30 lpm 
depending on which postion the operator has selected with 
the fl ow selector switch.
AUTO-OFF
When the throttle control switch is in the "AUTO-OFF" posi-
tion, the engine speed is held to maintain 5 gpm/19 lpm or 
8 gpm/30 lpm depending on which position the operator 
has selected with the fl ow selector switch. When a tool is 
not being used the engine will not return to idle until either 
the fl ow selector switch is turned to the OFF position or the 
throttle control switch is turned to AUTO-ON.
Note:
It may be necessary to reset the Controller.
