NOTICE
If you are unable to detect a setting on either step 3 or 7, more or less
air may be needed to achieve a proper combustion window. Loosen the
Bolt (#4 at left) and open the Air Band (#2 at left) in 1/4” increments.
Repeat steps 3-8 until proper combustion window is achieved.
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.
TEST WATER & FUEL PRESSURE: These procedures should be
performed by an authorized service technician.
TEST WATER TEMPERATURE: This procedure should be performed by
an authorized service technician.
MAINTENANCE - EVERY 6 MONTHS
MAINTENANCE - EVERY 12 MONTHS
REPLACE FUEL FILTER – Follow the instructions specified on the fuel
filter for correct procedure.
DELIME COIL – A loss in pressure may signify that the coil needs to be
delimed. Do this procedure on a periodic basis.
1. Mix non-caustic deliming powder/solution in float tank (optional)
according to package directions.
2. Remove the nozzle from the wand. Place a nylon stocking over the
wand assembly to collect debris, then place the wand assembly into
the float tank.
3. Ensure the trigger gun is open and start the engine to allow water to
circulate through the system. Allow process to continue for 2-4 hours
(Consult deliming agent package directions for exact time).
4. Once process is complete, turn off engine. Drain and clean the
float tank, remove the nylon stocking, and clean the gun and wand
assembly.
5. Flush the entire system with clean, fresh water and place the nozzle in
the wand assembly.
6. Dispose of deliming solution according to local, state, and federal
regulations.
TEST VOLTAGE AND AMP DRAW - Use a voltmeter and amp meter to
test the machine for correct voltage and amperage. If you do not have
these instruments or are unsure of how to perform these tests, this
procedure should be performed by an authorized service technician.
INSPECT BURNER FUEL PUMP INTERNAL FILTER – This procedure
should be performed by an authorized service technician.
CHECK BURNER ELECTRODES - This procedure should be performed
by an authorized service technician.
REPLACE FUEL NOZZLE - This procedure should be performed by an
authorized service technician.
