the system. Any further turning of the unloader will cause the pressure to spike when the wand
trigger is released, resulting in possible damage to the machine. To avoid this effect, loosen the
unloader (counter-clockwise) until the pressure just starts to drop (see pump head pressure
gauge) and until it no longer exceeds the maximum pressure rating for the machine.
7. You are now ready to start the cleaning operation - Pull trigger on the pressure wand
assembly to start cleaning. To stop the pressurized water, release the trigger. DO NOT
LEAVE UNIT RUNNING WHEN NOT IN USE.
8. To stop Burner operation – Turn BURNER switch to ‘PUMP’ (or to ‘OFF’ for Auto start
stop models) and run pump for two minutes with trigger gun pulled to allow coil to cool down.
After cooling period is complete, turn off main power to motor by turning BURNER switch to
‘OFF’ (turn PUMP switch to ‘OFF’ if equipped with auto start stop). Squeeze and release the
trigger for the second time in order to relieve the pump system of pressure.
9. Prior to storage – Inspect pressure washer for any damage or required maintenance. If your
machine is to be exposed to cold weather, please refer to winter pump/coil instructions found in
