Working with detergents
When cleaning with the pressure washer, some cleaning
tasks can be solved with water alone, but for most tasks
cleaning with detergent allows the user to remove the dirt
more effectively.
mWARNING! To apply detergents you must be operating
at low pressure. This provides a gentle application of the
detergent, with the pressure equivalent to a low-set garden
hose. The high pressure setting is used for cleaning. You
cannot apply detergents when working at high pressure.
• Set the pressure adjustment knob to the low pressure
(–) setting and turn the nozzle tip adjustment knob wide
open to apply detergent. (Fig. 20).
mWARNING! Use only detergents designed for
Pressure Washers. DO NOT USE household detergents, acids,
alkaline solutions, bleaches, solvents, ammable material, or
industrial grade solutions. These can damage the pump.
• Gently pull the detergent tank out of its storage position
and ll with detergent (Fig. 21). Push the tank back into its
storage position.
mCAUTION! Always test detergent in an inconspicuous
area before use.
• Turn on the pressure washer. Pull trigger to operate unit.
The liquid detergent will automatically mix with water and
discharge through the nozzle. Apply detergent from the
bottom to the top of the DRY surface to be cleaned.
NOTE: Wetting the surface rst is not recommended as it
dilutes the detergent and reduces its cleaning ability.
• Allow the detergent to remain on the surface for a short
time before rinsing with the pressure washer. Do not allow
the detergent to dry on the surface.
mCAUTION! Damage may occur to painted surfaces if
the detergent is allowed to dry on the surface. Wash and rinse
a small section at a time. Avoid working on hot surfaces or in
direct sunlight.
• Rinse with clean water under high pressure. On a vertical
surface, rinse from the bottom up, then rinse from the top
down to avoid streaking. Hold nozzle 6-8 inches away from
the work surface at a 45° angle.
• When you have nished using the detergent injection
system, remove the detergent suction tube from the
detergent bottle and insert it into 5 L (1 gallon) of fresh
water. Siphon water at low-pressure for one minute so that
all the detergent is ushed through the system. Remove the
detergent bottle and rinse it until it is thoroughly cleaned.
mCAUTION! Failure to clean properly will cause the
injection system to become clogged and inoperable.
mIMPORTANT! NEVER USE:
• Bleach, chlorine products and other corrosive chemicals.
• Liquids containing solvents (e.g. paint thinners, gasoline,
oils).
• Tri-sodium phosphate products.
• Ammonia products.
• Acid-based products.
• These chemicals will harm the unit and will damage the
cleaning surface.
Shutting down
1. Turn the switch to the OFF (0) position and unplug the
power cord from the outlet.
2. Turn off the water source.
3. Press trigger to release water pressure.
4. Disconnect the garden hose from the water inlet on the
unit.
5. Disconnect the high pressure hose from the high pressure
outlet.
6. Release trigger and engage the gun safety lock.
mWARNING! Turn off the water supply and squeeze the
trigger to depressurize the unit. Failure to do so could result in
personal injury due to discharge of high pressure water.
