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.

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.
