STARTING AND STOPPING THE PRESSURE
WASHER
See Figures 10 - 11.
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:
 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.

USING THE SPRAy WAND TRIGGER

See Figure 12.
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 13 - 14.
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),
25º (for general purpose or large surfaces), 0º (for spot
cleaning or high-to-reach areas), and the black nozzle for
using detergent.
OPERATION
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

 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 15.
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 the injection hose in the bottom of the detergent
bottle / 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.
Before shutting off the engine:
 Place the injection hose in a bucket of clean water.
 Flush for 1 - 2 minutes (spray clear water through the
spray wand).
 Shut off the engine.
NOTE: Shutting OFF ( O ) the engine will not relieve pressure
in the system. Pull trigger to release water pressure.
RINSING WITH THE PRESSURE WASHER
