hydraulic oil can penetrate and

drive pump mounting bolts. Carefully
remove the pump.
Component damage hazard.
Be sure to open the two hydraulic
tank valves and prime the pump
after installing the pump.

gauge to the test port on the drive pump.
2 Gasoline/LPG models: Remove the high
tension lead from the center of the ignition coil.

Contact with electrically charged
circuits may cause death or
serious injury. Remove all rings,
watches and other jewelry.

shutoff valve counterclockwise to the
position.
