Operation Manual - SP 305
If the charging system lamp won’t go out, you are not
charging the battery. The engine doesn’t need
electricity to run, so you may still be able to pump for a
short time before the emergency stop valves open and
send all the oil back to tank.
Don’t run the engine at high RPM until it has warmed
up by running for a couple of minutes.
You don’t need to lower the RPM of the engine to
adjust the strokes per minute output of this unit. The
following pages explain ways to control the unit.
Controlling the pump
These are the places on the unit that have operational
control functions:
• The control panel
• The volume control knob
• The throttle control
• The remote control box
• The driver side emergency stop switch
