BURNER ADJUSTMENT (only needed if white exhaust smoke appears)
The oil burner is preset, and performance tested at the factory (elevation 1100 feet). Different altitudes may require a one-time initial burner
adjustment.
CAUTION: If white smoke appears from the burner exhaust vent during start-up or operation, discontinue use and readjust air bands.
Specific steps for burner correction are given below.
Burner Correction
Adjusting the burner will require you to access the burner of the pressure washer while someone else is operating the
spray gun.
Detailed instructions:
1) Locate the Air Damper Lever on blower housing.
2) Make sure burner is cool to the touch before attempting to adjust.
3) Begin operation of the pressure washer and switch on the burner, as instructed in the operation section of the
manual. Have someone operate the spray gun so the burner fires.
4) Locate the air damper lever (Figure 5 below). Observe the position of the arrow on the lever relative to the
calibration numbers directly to the left. (0 is fully closed and 10 is fully open). (Note: Factory calibration starts out at
close to 5-1/2).

5) Locate and loosen the locking screw (Figure 5) and rotate the lever counter clockwise until black smoke appears
from the burner exhaust vent. Note which number the arrow now points to.
6) Slowly open the lever until white smoke just starts to appear.
7) Turn lever halfway back to the black smoke position previously noted. Tighten the locking screw.
