SERVICING OF A



DOUBLE-INSULATED PRODUCT

In a double-insulated product, two systems of insulation are provided instead of grounding. No grounding means is provided on a double-insulated product, nor should a means for grounding be added to the product. Servicing a double insulated product requires extreme care and knowledge of the system, and should be done only by qualiﬁ ed service personnel. Replacement parts for a double-insulated product must be identical to the parts they replace. A double-insulated product is marked with the words “DOUBLE INSULATION” or “DOUBLE INSULATED”. The symbol “ be marked on the product.

GROUND-FAULT

CIRCUIT-INTERRUPTER PROTECTION

This pressure washer is provided with a groundfault circuit-interrupter (GFCI) built into the plug of the power-supply cord. This device provides additional protection from the risk of electric shock. Should replacement of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.

WATER SUPPLY

(COLD WATER ONLY)

CAUTION

When connecting the water inlet to the water supply mains, local regulations of your water company must be observed. In some areas the unit must not be connected directly to the public drinking water supply. This is to ensure that there is no feedback of chemicals into the water supply. Direct connection via a receiver tank or backﬂ ow preventer, for example, is permitted.

Dirt in the feed water will damage the unit. To avoid this risk, we recommend ﬁ tting a water ﬁ lter.

■ Garden hose must be at least 1/2 inch or 5/8 inch (13 mm or 16 mm) in diameter.

■ Flow rate of water supply must not fall below 2 GPM (gallons per minute) (7.6 L/min.).

■ Flow rate can be determined by running the water for one minute into an empty 5 gallon (20 litre) container.

■ The water supply temperature must not exceed 40°C/104°F.

■ Never use the pressure washer to draw in water contaminated with solvents, e.g. paint thinners, gasoline, oil, etc.

■ Always prevent debris from being drawn into the unit by using a clean water source.

CLEANING TIPS

CAUTION

■ Before cleaning any surface, an inconspicuous area should be cleaned to test spray pattern and distance for maximum cleaning results.

■ If painted surfaces are peeling or chipping, use extreme caution as pressure washer may remove the loose paint from the surface.

■ When using on surfaces which might come in contact with food, ﬂ ush surfaces with plenty of drinking water.

Deck Cleaning

(with or without detergent) Pre-rinse deck and surrounding area with fresh water. If using detergent, apply to surface at low pressure. For best results, limit your work area to smaller sections of approximately 25 sq. ft. (2.3 m²). Allow detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. Rinse at high pressure in a long sweeping motion, keeping the spray nozzle approximately 3-6 in. (7.5-15 cm) from the cleaning surface. Always clean from top to bottom and from left to right. When moving on to a new section of the cleaning surface, be sure to overlap the previous section to eliminate stop marks and ensure a more even cleaning result.

Cement Patios, Brick and Stone

(with or without detergent) Pre-rinse cleaning surface with fresh water. If using detergent or degreaser, apply to surface at low pressure. For best results, limit your work area to smaller sections of approximately 25 sq. ft. (2.3 m²). Allow detergent or degreaser to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. Rinse at high pressure in a sweeping motion, keeping the spray nozzle approximately 3-6 in. (7.5 - 15 cm) from the cleaning surface. Always clean from top to bottom and from left to right. For removing extremely stubborn stains, use the Dirtblaster ® Nozzle.

Cars, Boats and Motorcycles

(with or without detergent) Pre-rinse vehicle with fresh water. If using detergent, apply to surface at low pressure. For best results, clean one side of vehicle at a time and always apply detergent from bottom to top. Do not allow detergent to dry on surface. If needed, use a rotating wash brush (not included) to remove stubborn dirt. Rinse at high pressure in a sweeping motion, keeping the spray nozzle approximately 6-8 in. (15-20 cm) from the cleaning surface (distance should increase when rinsing pin-striping or other sensitive surfaces). Always clean from top to bottom and from left to right. For best results, wipe surface dry with a chamois or soft dry cloth.

House Siding

(with or without detergent) Pre-rinse cleaning surface with fresh water. If using detergent, apply to surface at low pressure. For best results, limit your work area to sections of approximately 6 ft. (1.8 m) and always apply detergent from bottom to top. Allow detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. If surface appears to be drying, simply wet down surface with fresh water. If needed, use special rotating wash brush (not included) to remove stubborn dirt. Rinse at high pressure from top to bottom in an even sweeping motion, keeping the spray nozzle approximately 6 ft. (1.8 m) from the cleaning surface.
