1. Refer to “Risk of Bodily Injury / Detergents” pg. 11-12. Be certain to
wear protective safety attire as stated on pg. 15.
2. Prepare detergent solution according to label directions. (Never pump
acids, alkalines, abrasive fluids or solvents through the unit. Due to
the unknown and often corrosive characteristics of many detergents
commonly used in the pressure washer cleaning industry, it is
recommended to use only mild detergents with this unit.)
3. Fully immerse the detergent strainer into the detergent solution.
4. To apply solution; unlock the trigger gun and squeeze the trigger. In
a few moments a detergent/water mixture will exit the nozzle. Start
spraying the lower portion of the surface being cleaned and move up,
using long overlapping strokes. Applying from the bottom up helps
avoid streaking. Allow to soak briefly. (Avoid working on hot surfaces
or in direct sunlight to minimize the chances of the detergent drying,
which may result in damaging painted surfaces.) Be certain to rinse a
small section at a time.
5. To rinse; lock the trigger gun in the “OFF” position, securely quick-
connect the desired high pressure nozzle into the end of the wand.
Unlock the trigger gun and spray. It will take about 30 seconds to
purge all detergent from the line. For best rinsing results, start at the
top and work down.
6. Siphon a gallon of water through the low pressure detergent injection
system after each use. This prevents the possibility of corrosion or
detergent residue causing mechanical problems during the next use.
Storage & Maintenance Instructions
SPECIFIC MAINTENANCE
MAINTENANCE - EVERY 3 MONTHS
ENGINE: The engine instructions that accompany your unit detail specific
procedures for maintenance of the engine. Following the engine
manufacturer’s recommendations will extend engine work life.
PUMP: Change the pump oil after the first 50 hours of operation. After
initial change, every 3 months or 250 hour intervals are recommended.
If oil appears dirty or milky, changes may be required in greater
frequency. Use SAE20 or 30 non-detergent pump oil and fill only to
the center of the oil sight glass. DO NOT overfill.
NOZZLE: Water flow through the spray nozzle will erode the orifice,
making it larger, resulting in a pressure loss. Nozzles should be
replaced whenever pressure is less than 85% of the maximum. The
frequency of replacement will depend upon such variables as mineral
content in the water and number of hours the nozzle is used.
CHANGE WATER PUMP OIL: Ensure unit is off. Change the pump
oil after the first 50 hours of operation. After initial change, every 3
months or 500 hour intervals are recommended. If oil appears dirty or
milky, changes may be required in greater frequency. Use SAE20 or
30 non-detergent pump oil and fill only to the center of the oil sight
glass. DO NOT overfill.
REPLACE HIGH PRESSURE NOZZLE: Water flow through the spray
nozzle will erode the orifice, making it larger, resulting in a pressure
loss. Nozzles should be replaced whenever pressure is less than 85%
of the maximum. The frequency of replacement will depend upon such
variables as mineral content in the water and number of hours the
nozzle is used.
BELT INSPECTION: Ensure unit is off and remove the beltguards.
Inspect the v-belt for wear and tightness. If the v-belt needs to be
replaced or tightened, follow the procedures listed below:
Replacement:
1. Loosen the four pump mounting bolts (A).
2. Loosen the two alignment nuts approximately one inch on the
alignment bolts (B1 & B2).
3. Slide the pump toward the engine to loosen belts.
4. Remove and replace belt.
OPTIONS: HIGH PRESSURE DETERGENT
NOTICE
This feature is designed for use with mild detergents only. Since the
cleaning solution travels through the heat exchanger coil, DO NOT
use corrosives as they will cause extensive damage as well as pose a
considerable safety hazard.

SHUTDOWN:
1. Move the Burner switch to the OFF position.
2. Squeeze the trigger and discharge the water for a period of three minutes
to cool the heat exchanger and high pressure hose. Insufficient cool-down
periods for the high pressure hose will cause excessive wear and eventual
rupture of the hose.
3. Do not close the choke to stop the engine. Backfire or engine damage may
occur.
4. Move the engine key switch to the OFF position.
5. Turn off the water supply and trigger the gun momentarily to relieve trapped
pressure.
Disconnect and drain the high pressure hose, gun, and lance. Wipe the unit
clean. Store in a non-freezing environment.
OPTIONS:
HIGH PRESSURE DETERGENT: (Cleaning with Detergents)
NOTE: This feature is designed for use with mild detergents only. Since the
cleaning solution travels through various parts of the pressure washer, do
not use corrosives as they will cause extensive damage as well as pose a
considerable safety hazard.
1. Refer to "Risk of Bodily Injury / Detergents" pg. 8-9. Be certain to wear
protective safety attire as stated on pg. 12.
2. Prepare detergent solution according to label directions. (Never pump acids,
alkalines, abrasive fluids or solvents through the unit. Due to the unknown
and often corrosive characteristics of many detergents commonly used
in the pressure washer cleaning industry, it is recommended to use only
mild detergents with this unit.)
3. Fully immerse the strainer end of the clear vinyl detergent hose into the
detergent solution.
4. To apply solution; unlock the trigger gun and squeeze the trigger. In a few
moments a detergent/water mixture will exit the nozzle. Start spraying
the lower portion of the surface being cleaned and move up, using long
overlapping strokes. Applying from the bottom up helps avoid streaking.
Allow to soak briefly. Avoid working on hot surfaces or in direct sunlight to
minimize the chances of the detergent drying, which may result in damaging
surfaces. Be certain to apply cleaning solution to a small section at a time.
5. To rinse; lock the trigger gun in the "OFF" position. Turn the detergent
metering valve to the "OFF" position. Unlock the trigger gun and spray. It
will take about 30 seconds to purge all detergent from the line. For best
rinsing results, start at the top and work down.
6. Siphon a gallon of water through the detergent injection system after each
use. This prevents the possibility of corrosion or detergent residue causing
mechanical problems during the next use.
