Chemicals and Cleaning Solvents

Applying chemicals or cleaning solvents is a low-pressure operation. NOTE: Use only soaps and chemicals designed for pressure washer use. Do not use bleach.

TO APPLY CHEMICALS AND SOLVENTS
1.	Press chemical hose (T) onto barbed
	fitting located near high pressure hose	T
	connection of pump as shown.
2.	Place the other end of chemical hose
	with filter on it into the container holding
	chemical/cleaning solution.

NOTE: For every 7 gallons (26.5 liters) of water pumped 1 gallon (3.8 liters) of chemical/cleaning solution will be used.

3.Install low-pressure (black) nozzle into quick connect fitting of spray wand, refer Spray Wand Nozzles.

4.After use of chemicals, place chemical hose into container of clean water and draw clean water through chemical injection system to rinse system thoroughly. If chemicals remain in the pump it could be damaged. Pumps damaged due to chemicals will not be covered under warranty.

Starting

WARNING: To reduce the risk of injury, read the pressure washer instruction manual and the engine instruction manual before starting pressure washer.

DANGER: Risk of fluid injection and laceration. When using the high- pressure setting, DO NOT allow the high-pressure spray to come in contact with unprotected skin, eyes, or with any pets or animals. Serious injury will occur.

•Your washer operates at fluid pressures and velocities high enough to penetrate human and animal flesh, which could result in amputation or other serious injury. Leaks caused by loose fit- tings or worn or damaged hoses can result in injection injuries. DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a physician immediately!

WARNING: Risk of fire, asphyxiation and burning. NEVER fill fuel tank when engine is running or hot. Do not smoke when filling fuel tank.

•NEVER fill fuel tank completely. Fill tank to 1/2" (12.7 mm) below bottom of filler neck to provide space for fuel expansion. Wipe any fuel spillage from engine and equipment before starting engine.

•NEVER run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, an odorless and deadly gas.
