STARTING AND STOPPING THE PRESSURE
WASHER
See Figures 10 - 12, page iv.
CAUTION:
Do not run the pump without the water supply connected
and turned on.
Before starting the engine:
 Connect all hoses.
 Check all fluids (lubricant and gas).
 Turn on the garden hose then squeeze the trigger to
relieve air pressure; hold the trigger until a steady stream
of water appears.
To start the engine:
 Turn the fuel valve to the ON position.
 Put the engine switch in the ON position.
 Pull choke.
 Grasp the recoil starter and pull slowly until resistance is
felt. Give the recoil starter a short, brisk pull to start the
engine.
NOTE: Do not allow the recoil starter to snap back after
starting; return it gently to its original place.
 Let engine run for several seconds, then push choke in.
To stop the engine:
 Put the engine switch in the OFF position.
 Turn the fuel valve to the OFF position.
USING THE SPRAy WAND TRIGGER
See Figure 13, page v.
For greater control and safety, keep both hands on the
trigger handle at all times.
 Pull back and hold the trigger to operate the pressure
washer.
 Release the trigger to stop the flow of water through the
nozzle.
To engage the lock out:
 Push up on the lock out until it clicks into the slot.
To disengage the lock out:
 Push the lock out down and into its original position.
For the most effective cleaning, the spray nozzle should be
between 8 in. and 24 in. from the surface to be cleaned. If
the spray is too close it can damage the cleaning surface.
SELECTING THE RIGHT NOZZLE FOR THE
JOB
See Figures 14 - 15, page v.
Before starting any cleaning job, determine the best nozzle
for the job. Each of the nozzles has a different spray
pattern. The nozzle patterns are: 40º (for gentle rinse),
OPERATION
25º (for general purpose or large surfaces), 0º (for spot
cleaning or high-to-reach areas), and the black nozzle for
using detergent.
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 may 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.
 Remove the nozzle by placing hand over nozzle then
pulling back the quick-connect collar. Place nozzle in the
nozzle storage area on the top of the machine.
WASHING WITH DETERGENT
See Figure 16, page v.
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.
 Remove the cap from the detergent container and pour
detergent in the container. Replace cap on container.
 Install the black nozzle on the spray wand.
 Spray the detergent on a dry surface using long, even,
overlapping strokes. To prevent streaking, do not allow
detergent to dry on the surface.
NOTE: To use a detergent bottle, open the detergent container
cap. Next, remove the filter from the end of the injection hose
then slide the hose out of the cap. Place the injection hose
filter back on the hose and place the hose in the bottom of
the bottle.
For detergent application:
With the black nozzle installed on the spray wand and the
engine turned off, submerge the hose and black filter down
into the detergent container as far as it will go.
