1. The pressure washer should be as close as possible to the water
supply.
2. Locate the pressure washer on a solid, level surface with a gentle
slope to prevent water from building up in the work area. Excess
water can make surfaces slippery.
3. Position the unit so the operator has easy access to the pressure
washer and its controls.
4. To prevent damage and excessive hose wear, locate the pressure
washer so the hose does NOT extend across tra c areas. Make sure
there are no kinks or twists in the hose.
5. Use extension cords of at least 12-3 gauge for lengths up to 50 feet
or 10-3 gauge for lengths up to 100 feet. Check the extension cord
to make sure it is not damaged or frayed. The outlet should have an
amperage rating of 20 amps or greater and should have a Ground
Fault Circuit Interrupter (GFCI).
6. Do not use the pressure washer outdoors if it is raining, and do not
spray the motor or any of its connections.
7. Do not use chemicals or agents which are not compatible with the
Buna-N and PVC (polyvinyl) or neoprene covering of the hose.
8. Do not run acids or hard caustics through the pump.
9. Check to determine if the water supply can exceed the output of the
pump. The output of this unit is 2.1 gpm (gallons per minute), so the
water supply must deliver at least 2.5 gpm.
Calculate gpm ow rate by running the water supply into a
pail for one minute. Measure the gallons in the pail. If it is at
least 2.5 gallons in the minute, your supply is adequate. Your
water supply must be clean and free of debris. Use water
with a temperature of less than 140° F.
