starting the PressUre Washer
1. Turn on the water supply to the proper gpm flow rate.
2. Plug power cord into properly grounded outlet.
3. Turn nozzle to low pressure and squeeze trigger.
4. Turn “ON/OFF” switch to the “ON” position and wait until a
constant stream of water comes out. Adjust nozzle sleeves to
achieve proper pressure and coverage area.
dUring oPeration
1. Observe all safety instructions through this manual.
2. Do not allow the machine to run with the wand not squeezed,
“OFF”, for more than 2 minutes (30 seconds with water
temperature above 80° F.)
When the wand trigger is released the pump
does not stop pumping. Water is routed through
a bypass circuit which builds up heat. If the water
temperature becomes too high, damage to the
seals, packings and other parts may result.
3. Check pump, connections and hose for water and oil leaks.
Replace worn parts.
stoPPing the PressUre Washer
1. Rinse and close the downstream chemical injector.
2. Turn the motor power switch to the “OFF” position.
3. Turn off water supply.
4. Squeeze the trigger on the wand to relieve the system water
pressure and drain as much water as possible.
5. Spray the backside of the nozzle with a lubricant and work the
nozzle back and forth from high pressure to low pressure. This
will help keep the nozzle from sticking.
6. Follow this procedure each time the machine is stopped. Having
the nozzle set at low pressure and squeezing the trigger on the
gun when you start the unit will reduce the startup load of the
unit.
