Operation Maintenance

Vibration Hazard:

This tool vibrates during use. Repeated or

long-term exposure to vibration may cause

temporary or permanent physical injury,

particularly to the hands, arms and shoulders.

To reduce the risk of vibration-related injury:

1. Anyone using vibrating tools regularly or for an

extended period should first be examined by a

doctor and then have regular medical checkups

to ensure medical problems are not being

caused or worsened from use. Pregnant women

or people who have impaired blood circulation

to the hand, past hand injuries, nervous system

disorders, diabetes, or Raynaud’s Disease should

not use this tool. If you feel any medical or

physical symptoms related to vibration (such as

tingling, numbness, and white or blue fingers),

seek medical advice as soon as possible.

2. Do not smoke during use. Nicotine reduces

the blood supply to the hands and fingers,

increasing the risk of vibration-related injury.

3. Wear suitable gloves to reduce the

vibration effects on the user.

4. Use tools with the lowest vibration when there

is a choice between different processes.

5. Include vibration-free periods each day of work.

6. Grip tool as lightly as possible (while still keeping

Pressure Washer Operation

WARNING

Do not direct spray from the pressure washer at a person or an

animal. The water stream could cause serious injury.

Caution

Use the pressure washer only on surfaces able to withstand the force of the spray.

1. Replace the non-vented brass oil plug with

the aluminum Pump Breather Plug before

first use. The Pump Breather Plug must be

used whenever the pressure washer is used.

The brass oil plug (without the breather hole)

should be used for transporting only.

2. Choose the Nozzle that best meets the needs

of the job. Only use the Nozzles on surfaces

capable of withstanding the force of the spray.

Only use the Black Nozzle when using pressure

washer detergent. The power of the other

Nozzles will propel mist back at the operator

and can embed detergent into the surface.

3. Pull back the quick connect collar and push the

Nozzle onto the end of the Wand. Make sure the

quick connect collar locks the Nozzle in place.

4. Turn the water supply on and hold down the

Trigger to start the stream. Be aware that

when it is first started, the gun will kick.

5. It is best to start at a low pressure setting, and adjust

the pressure upwards. Test spray the edge of the

surface to be cleaned first to make sure that the

stream is not too strong for the surface. If the stream

damages the surface, turn the Pressure Regulator

Knob counterclockwise to reduce the pressure.

Moving further away from the surface being cleaned

will also reduce the pressure being applied to the

surface. If the stream is still too strong, turn the

engine off, turn the water supply off, discharge the

excess pressure from the gun by squeezing the

Trigger, and change to a lower pressure Nozzle.

6. To increase the pressure, turn the

Pressure Regulator Knob clockwise.

7. Hold the Wand at about a 45° angle when cleaning;

spraying the surface directly could embed dirt into the

surface (especially with the high pressure Nozzles).

Spray at a distance of about three to five feet.

8. Clean vertical and sloped surfaces from the top down.

9. When cleaning horizontal surfaces, occasionally

use the stream to clear the area of excess water.

10. CAUTION Do not allow the Pressure Washer to idle

without the Trigger held down, for more than two

minutes. The water will heat up and damage the

Pressure Washer. RISK OF BURNS! The pump will

also expel very hot water if allowed to idle too long.

11. Hold the Trigger down and move the Wand back

and forth slowly and steadily to pressure wash the

surface. Take special care when spraying surfaces

made of two different materials (brick and mortar,

for example), so as to not damage the softer of

the two materials during pressure washing.

12. If the surface is streaked or uneven at the end

of a job, switch to a Nozzle that has a wider

spray pattern to blend the affected area.

13. When finished; release the Trigger on the
