Stanley Black & Decker GT18B02 User Manual

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.

Figure 3. Control Panel

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.

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.

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.

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.

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.

Before starting the engine make sure the flow selector 

switch is 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, 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, 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.

When finished operating the tool, move the flow selector 

switch to the OFF position.
