WARNING: Flying objects could cause risk of serious
injury. Do not attempt to change nozzles while pressure
washer is running. Turn engine off before changing
nozzles.
1. Pull quick-connect coupler (E) back and insert nozzle
(K).
2. Release quick-connect coupler and twist nozzle to
make sure it is secure in coupler.
WARNING: Flying object could cause risk of serious injury. Ensure nozzle
is completely inserted in quick-connect socket and quick-connect collar is
fully engaged (forward) before squeezing gun trigger.
HOW TO APPLY CHEMICALS/CLEANING SOLVENTS (FIG. 8)
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:
1. Ensure detergent siphon hose (F, Figure 8) is attached
to barbed fitting location near high pressure hose
connection of pump as shown.
2. Place other end of detergent siphon hose with
filter on it into container holding chemical/cleaning
solution. NOTE: For every 7 gallons of water pumped
1 gallon of chemical/cleaning solution will be used.
3. Install low pressure (black) nozzle into quick connect fitting of spray wand, see
How To Use Spray Wand paragraph in this section.
4. After use of chemicals, place detergent siphon 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 chemical residue will not be covered under warranty.
NOTE: Chemicals and soaps will not siphon if the black soap nozzle is not installed
on the spray wand.
STARTING (FIG. 9–12)
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 fittings or worn or damaged hoses can result in injection
injuries. DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a physician
immediately!
DANGER: Carbon Monoxide. Using an engine indoors can kill you in
minutes. Engine exhaust contains high levels of carbon monoxide (CO), a
poisonous gas you cannot see or smell. You may be breathing CO even if you
do not smell engine exhaust.
• Breathing ex haust fumes will cause se ri ous injury or death! En gine exhaust
contains carbon mon ox ide, an odorless and deadly gas.
