in a confined area.
Engine Start-Up and Pressure Adjustment
NOTE! The KJ-2200 Jetter has a pulse actuator on the
pump. This actuator must be in the OFF (rotate
counter-clockwise) position prior to starting the jet-
ter (Figure 3). To obtain maximum pressure, the
pulse control must be OFF.
Figure 3 – Pulse Actuator OFF
1. Turn the unloader valve counter-clockwise to insure
the pressure is backed down.
2. Turn the fuel valve to the ON position.
3. Move the choke lever to the CLOSE position.
NOTE! Choke may not be needed if engine is warm or
the air temperature is high.
4. Move the throttle lever slightly to the left.
5. Start the engine:
• Turn the engine switch to the ON position.

8. If the jetter will not generate 2200 PSI:
• Make sure the engine throttle is adjusted properly.
• Make sure the water faucet is completely OPEN
and the inlet supply valve is OPEN.
• Check the filter screen at the inlet port to the jetter.
Make certain it is clear of debris.
• Make sure the pulse actuator is in the OFF posi-
tion.
• Cycle the pulse actuator ON and OFF several
times while the jetter is running to clear any trapped
air in the system.
• Rotate unloader valve clockwise to make sure it in-
creases pressure.
Normal Jetting
1. For normal jetting, turn the pulse actuator to the OFF
position and guide the hose into the line by hand.
2. When the jetter nozzle encounters a bend, its ad-
vance will usually slow or stop. The jetter hose has a
slight bend or set to it. The reverse thrust of the noz-
