Controls, Startup, FOR 5 GPM OPERATION | Stanley Black & Decker GT18B02

OPERATION

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 flow 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.

One hydraulic tool can be connected to the tool circuit. The circuit is activated by turning the flow 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 flow 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 flow is regulated automatically when the trigger on the tool is 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 flow 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 flow selector switch. When a tool is not being used the engine will not return to idle until either the flow 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.

12 ► GT18B01-B02 User Manual

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.

STARTUP

Before starting the engine make sure the flow selector switch is in the OFF position.

Note:

The power unit will not start if the flow 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 flow selector switch is in the OFF position.

Turn the Ignition Switch to the START position. After the engine starts, release the switch.

Gradually push in the choke knob as the engine begins to idle smoothly.

Allow the engine to warm up.

Connect hoses and the tool as desrcribed in this manual.

FOR 5 GPM OPERATION

For 5 gpm operation, select mode of operation with the Throttle Control switch, either auto-idle-on or the auto-idle- off position. Move the flow selector switch to the 5 gpm position.

When finished operating the tool, move the flow selector switch to the OFF position.

FOR 8 GPM OPERATION

For 8 gpm operation, select mode of operation with the Throttle Control Switch, either auto-idle-on or the auto-idle- off position. Move the flow selector switch to the 8 gpm position.
