USING THE HIGH PRESSURE HOSE
WARNING:
Injection hazard. Fully unwrap and straighten high
pressure hose prior to and during each use and do not
allow it to become kinked. The high pressure hose features
an outer covering that provides strength to the hose. If the
outer covering becomes damaged, stop using the hose
and replace it immediately. A kinked or damaged hose
can develop a high pressure leak and result in a possible
injection or other serious personal injury.
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.
WASHING WITH DETERGENT
See Figures 20 - 21.
As sold, this unit is designed for use with "downstream" pres-
sure washer detergents. To convert for use with "upstream"
detergents, contact customer service or a qualified service
center for more information.
NOTICE:
USE ONLY DETERGENTS DESIGNED FOR PRESSURE
WASHERS. Do not use household detergents, acids,
alkalines, bleaches, solvents, flammable material, or
industrial grade solutions, which can damage the pump
or cause property damage. Many detergents may require
mixing prior to use. Prepare cleaning solution as instructed
on the solution bottle. Always test in an inconspicuous
area before beginning.
 Remove the cap from the soap tank and pour pressure
washer detergent in the tank. Replace cap on tank.
NOTE: The machine setting of this unit is 20:1, which
usually allows the use of 1 gallon pressure washer
detergent without further dilution. Check your detergent
instructions to be sure additional dilution is not necessary.
 Install the blue soap nozzle on the spray wand.
 Squeeze the trigger and wait approximately 5 seconds for
the detergent to appear.
 Spray the detergent on a dry surface using long, even,
overlapping strokes. To prevent streaking, do not allow
detergent to dry on the surface.
OPERATION
Before shutting off the engine:
 Fill the soap tank with clean water.
 Spray the clear water through the spray wand until the
tank is empty.
 If any detergent remains in the spray, repeat with a second
tank of clean water.
 Shut off the engine.
NOTE: Shutting off the engine will not relieve pressure in the
system. Pull trigger to release water pressure.
RINSING WITH THE PRESSURE WASHER
 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 soap nozzle and place in the nozzle storage
area.
 Select the right nozzle for the job. See the chart shown
earlier in the manual to select the appropriate nozzle.
 Start at the top of the area to be rinsed and work down,
overlapping the strokes.
USING PUMP PROTECTOR
See Figure 22.
Regular use of a commercially available pump protector
prolongs the life of the pressure washer by removing hard
water mineral deposits, lubricating pump seals and pistons,
and preventing freeze damage. Pump protector should be
added to the unit after every use and before storage. Pump
protector can be purchased at the retailer where you purchased
your pressure washer, or by calling customer service.
The instructions that follow are typical for adding pump
protector but you should always verify the specific instructions
provided by the manufacturer of the pump protector used.
 Turn off the pressure washer engine and shut off the water
supply. Pull trigger to release water pressure.
 Disconnect garden hose and high pressure hose.
 Unscrew threaded top from pump protector bottle and
remove paper seal from bottle. Reinstall top on bottle and
tighten securely.
NOTE: The rubber seal should remain inside the threaded
top. If it comes out, be sure to replace before reinstalling
the top.
 Remove bottle cap and attach threaded end of bottle
securely to pressure washer pump water intake.
 Squeeze bottle to inject contents into pump.
 With engine switch off, pull starter grip and rope to cycle
pump, then squeeze bottle again to guarantee complete
coverage.
 Pump is protected when the protector fluid exits the pump
outlet.
