*
Switch the directional valve to its “Neutral –0” position.
*
Switch the choke lever to its “CHOKE” position.
*
Turn fuel shutoff valve to the “OPEN” position.
*
Pull the cord until resistance is felt, let the cord be retracted and then pull fast. Repeat this if the
engine does not start the first time.
*
Guide the starting cord back after starting.
Switch the choke lever to “RUN” when the engine has warmed up after approx. 20 - 30 sec. (begins to run
irregularly).
NOTE: Start in the “RUN” position if the engine is still warm. Start in the “CHOKE” position if the engine
is cold or runs out of gasoline during operation.
5.2.5 Operating:
The directional valve can be set to either of the OPERATION positions – 1 or 2 as soon as the engine is
running regularly and a tool is connected. Use the tool selector handle to choose the position for the tool
that is required to be used. The oil now flows through the discharge hose to the tool and back to the pump.
The tool can perform its function by operating the tool’s dead-man control. The pump automatically
supplies the required pressure.
