How to Use Spray Tips
The nozzle extension quick–connect allows the use of
several different spray tips. Each spray tip provides a
different spray pattern (Figure 11).
Follow these instructions to change spray tips:
1. Engage trigger lock on spray gun.
2. Pull back collar on quick–connect and pull current
spray tip off.
3. Select desired spray tip:
• For gentle rinse, select white 40° or green 25°
spray tip.
• To scour surface, select yellow 15° or red 0° spray
tip.
• To apply detergent, select black spray tip.
4. Pull back on collar, insert new spray tip and release collar.
Tug on spray tip to make sure it is securely in place.
5. For most effective cleaning, keep spray tip from 8 to
24 inches away from cleaning surface.
6. DO NOT get closer than 6 inches when cleaning
automobile tires.
Cleaning and Applying Detergent
IMPORTANT: Use detergents designed specifically
for pressure washers. Household detergents could
damage the pump.
To apply detergent follow these steps:
1. Review spray tip use.
2. Prepare detergent solution as required by manufacturer.
3. Place detergent siphon tube/filter into detergent
container.
4. Make sure black spray tip is installed.
NOTE: Detergent cannot be applied with high pressure
spray tips (White, Green,Yellow, or Red).
• NEVER exchange spray tips without engaging the trigger lock
on the spray gun.
A pressure washer produces a high pressure spray
which increases risk of injury and damage to unit.
CAUTION
CAUTION
• Starting the engine without all the hoses connected and
without the water turned ON will damage the pump.
• Damage to equipment resulting from failure to follow this
instruction will void warranty.
You must attach all hoses before you start the engine.
CAUTION
• When inserting the filter into a detergent solution bottle,
route the tube so as to keep it from inadvertently contacting
the hot muffler.
Keep the detergent siphon tube from coming in contact
with the hot muffler.
