 WARNING:
NEVER change nozzles without locking the lock out on
the trigger handle and NEVER point the wand at your
face or at others. The quick-connect feature contains
small springs that could eject the nozzle with some force.
Failure to heed this could cause personal injury.
Using the quick-connect collar, changing nozzles is easy.

Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
To connect a nozzle to the trigger handle:

Engage the lock out on the trigger handle by pushing up
on the lock out until it clicks into the slot.
 Pull back the quick-connect collar.
 Push the nozzle into place in the spray wand.
 Push the collar forward so that the nozzle is secured
properly. Check to see that the nozzle is secure.
To disconnect a nozzle from the trigger handle once the
cleaning job is complete:

Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
 Engage the lock out on the trigger handle by pushing up
on the lock out until it clicks into the slot.
 Pull back and hold the quick-connect collar.
 Remove the nozzle by pulling it from the quick-connect
collar. Place nozzle in the nozzle storage area on the top
of the machine.
USING THE HIGH PRESSURE HOSE
The high pressure hose features an outer covering that pro-
vides strength to the hose. If the outer covering becomes
damaged, the hose must be replaced immediately.
Do not
use a high pressure hose if the outer covering is damaged.
To prevent damage to the outer covering:

Inspect the hose before every use.
 Fully unwrap and straighten hose before use.
 Do not allow the high pressure hose to be kinked.
 Keep hose away from hot surfaces and sharp edges.
 Do not pull unit by high pressure hose.
 Do not allow hose to be crushed or wrapped around
objects.
ATTACHING INJECTION HOSE
See Figure 14.
Before detergent can be used with this machine, the injection
hose must be attached.

Open the cap of your detergent container.
 Push the injection hose filter onto the end of the injection
hose. Insert the injection hose into your cleaning solu-
tion so the injection hose filter rests at the bottom of the
detergent container.
 Push the open end of the injection hose securely over
the fitting as shown in figure 14.
WASHING WITH DETERGENT
See Figure 15.
As sold, this unit is designed for use with “downstream” pres-
sure washer detergents. To convert for use with “upstream”
detergents, contact an authorized customer service center
for more information.
Use only detergents designed for pressure washers; house-
hold detergents, acids, alkalines, bleaches, solvents, flam-
mable material, or industrial grade solutions can damage
the pump. Many detergents may require mixing prior to use.
Prepare cleaning solution as instructed on the solution bottle.

Place one end of the injection hose into your detergent
container and attach the other end to the pump.
NOTE: The machine setting of this unit is 1:20, which
usually allows the use of 1 gallon detergent without further
dilution. Check your detergent instructions to be sure
additional dilution is not necessary.
