OPERATION
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.
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 quickconnect 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.

MAINTENANCE
Storage & Maintenance Instructions
SPECIFIC MAINTENANCE
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.
MAINTENANCE - EVERY 3 MONTHS
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.

25
MAINTENANCE
BELT TENSION ADJUSTMENT: To maintain peak performance of your
pressure washer, it may be necessary to adjust the belt tension on
occasion. Follow the procedure outlined below.
1. Remove the belt guard and loosen the two nuts on each side of the
pump (Reference A). There are a total of 4 nuts.
2. Turn the cap screw (Reference B) clockwise until a 1/4 inch belt
deflection is noticed between the pulleys.
3. Tighten the side nuts (Reference A).
4. Put a straight edge across both pulleys. Pulley alignment is critical for
proper performance and service life. If necessary, loosen one set of
pulley screws and adjust in or out to properly align. Tighten the pulley
screws and check the tension again.
5. Replace the beltguard and tighten the fasteners securely.
BURNER AIR ADJUSTMENT: The air shutter has been factory preset
for proper operation between sea level and 2000 feet elevation at
standard conditions (60°F ambient water and air temperatures).
In colder temperatures or higher altitudes, it may be necessary to
adjust the air supply to the combustion chamber. This adjustment will
maximize burner efficiency and avoid inefficient operation or excessive
sooting of the heat exchanger coil. A smoke spot test is recommended
during any air shutter and band adjustment. If you do not have the
equipment to perform a smoke spot test, follow the procedures listed
below.
1. The machine must be running and the burner ON.
2. Loosen the Locking Screw (#3 at left) on the shutter.
3. Check for smoke from the heat exchanger exhaust. If smoke is not
present, slowly close the Air Shutter (#1 at left) by moving the dial
counterclockwise to a lower number. Continue moving the dial until
smoke appears.
4. Record this setting.
5. Open Air Shutter (#1 at left) two increments. Example: If Air Shutter
was set at 2, move it to 4.
6. Slowly trigger the gun on and off. This will cause the burner to turn on
and off. Look for a smoke puff when the burner ignites.
7. Repeat steps 5 and 6 until a smoke puff is noticed. Record the Air
Shutter Setting.
8. The difference between the recorded settings in steps 4 and 7 is the
combustion window. Set the dial 1/2 way between these settings.
NOTICE
