9.Startup and Stopping Procedure
9.1 How to Start Your Pressure Washer
To start your pressure jetter for the first time, follow these instructions
step-by-step. This starting information also applies if you have let the pressure
washer sit idle for at least a day.
1. Place pressure jetter near an outside water source capable of supplying
water at a flow rate at least 5GPM/19LPM and no less than 20PSI/1.3BAR at
pressure washer end of garden hose.
2. Check that high pressure hose is tightly connected to spray gun and pump.
3. Make sure unit is in a level position.
4. Uncoil high pressure hose completely before using pressure washer.
5. Connect garden hose to water inlet on pressure washer pump.
6. Turn ON water, point gun in a safe direction and squeeze trigger to purge
pump system of air and impurities.
7. Pulling out the high pressure jetting hose from the hose reel.
8. Choose the right size and type of nozzle you want to use, warp appropriate seal
tape on the fitting of jetting hose, tighten the nozzle
9. Make sure the BATTERY is good condition and well connected.
10. Turn fuel shut-off valve to ON position (if equipped).
11. Move Turn engine on/off switch to ON position (if equipped).
12. Start engine as follows:
Cold engine: Place throttle control midway between SLOW and FAST positions.
Place choke control into ON position.
Warm engine: Place throttle control midway between SLOW and FAST positions.
Return choke to OFF position as soon as engine starts. A warm engine usually
does not require choke on.
13. Retractable Start: Slowly pull starter handle until just past compression-STOP!
Return starter handle; firmly pull straight out to avoid excessive rope wear from
starter rope guide.
Electric Start：Activate starter switch. Release switch as soon as engine starts.
If starter does not turn engine over, shut off starter immediately. DO NOT make
further attempts to start engine until condition is corrected. DO NOT jump start.
See your Kohler authorized dealer for trouble analysis.
14. Gradually return choke control to OFF position after engine starts and warms up.
9.2 How to Stop Your Pressure Jetter
1. To stop the engine method 1: Turn engine switch to OFF, close the fuel valve.
2. To stop the engine method 2: Close the Fuel Valve and wait for the engine to stop.
NOTE: DO NOT run the pump without the water supply connected and turned on.
Damage resulting from failure to follow this instruction will VOID WARRANTY.
NOTE: Using the electric starter for more than 5 seconds at a
time will overheat the starter motor and can damage it.
IMPORTANT: Allow the Engine to run at no load, low pressure
for five minutes after each start-up so Engine can stabilize.
NOTE: Avoid letting fuel remain in the carburetor for lone
periods as this can clog carburetor passages with impurities
resulting in malfunctions.

10. Operation
10.1 Jet Nozzle Selection
1. Penetrating nozzle have an orifice in the front to cut through the stoppage, and a
tight/narrow jetting angle (15°) has more driving power for long runs.
2. Flushing nozzle features with no front orifice and a wide spray pattern (40°) does
a better job of cutting the grease off of the walls of the pipe.
3. A combination of nozzles may be required to clear a line. Always turn off the
machine and turn off output valve before changing nozzles.
4. Check nozzles before and after each use for clogged holes which can cause
pressure to increase to dangerously high levels and damage the pump.
10.2 Jetting the Drain
1. Release the locking pin on the hose reel, pull the hose out and Insert the jetter
nozzle into the drain about 10cm in the direction of the clog. Hand hold the hose to control
its movement, turn on the cock of the hose real, adjusting the pressure as needed. The
reverse jet thrusters on the nozzle will help pull the hose into the drain.
2. When jetting a drain, typically the hose is fed into the drain the full distance to be cleaned
and slowly pulled back. This allows the high pressure water directed at
the drain walls to remove build-up.
3. Feed the hose in the as far as needs to be cleaned. If the hose stops, it has encountered
some type of obstruction. If the nozzle cannot pass through an obstruction, such as a
change in direction (trap, turn, etc.) or a blockage. Rotate
the hose a quarter to half turn to orient the set of the hose to the direction change
(If the hose is rotated, once through the obstruction, turn the hose back to help prevent
kinks). Use the pulse mode.
4. Once past a blockage, take the time to clean that section of drain prior to moving forward.
Move several feet past the area of the obstruction and slowly pull the
nozzle back through the area of the obstruction. Do this several times and then
move further into the drain. Watch the drain water level. If the water level gets too high, you
may need to turn the jetter OFF and allow the water to drain prior to continuing.
5. Jetting when the line is full of water is less effective than when the line is empty.
6. Do not allow the jetter to run for extended period of time with the COCK VALVE OFF.
When it is OFF, water recirculates in the pump and cause the water to heat up. This can
cause the pump thermal overload to open.
7. Once the nozzle is the desired distance into the drain, slowly (1 ft/30 cm/min for
heavy drain accumulations) pull the nozzle back through the drain. Use one hand to control
the hose and the other to wind the hose onto the reel. Watch as the nozzle gets closer to
the drain opening that the nozzle does not come out of the drain while water is flowing.
This could allow the hose to whip around and cause striking and high pressure fluid
injuries. Always control the hose. Look for the mark on the hose near the nozzle. Turn off
the cock to shut off the water flow.
10.3 Using the Pulse Mode
When manipulating the hose is not enough to pass through a direction change or
obstruction, the pulse mode should be used. The pulse mode induces large variation in
water pressure that causes the hose to vibrate, easing hose advancement.
1. Turn the pulse actuator lever clockwise to the °PulseH position. In pulse mode,
the pressure gauge will read less than full pressure. This is normal.
2. If needed, use sharp thrusts of the hose and hose rotation to help the nozzle
through the obstruction.
3. Once through the obstruction, turn the pulse actuator lever counter-clockwise to
the “Pressure” position. Do not leave the jetter in pulse mode any longer than
needed to pass through an obstruction. Excessive use of the pulse feature can
cause premature wear on hoses and system.

10. Operation (Continued)
10.4-1 Slowly fed and pull back
At times, it will be necessary to move the hose
slightly in and out of the drain line to assist the
Jetting nozzle in clearing stubborn clogs,
Obstructions, or tight corners
10.4-2 When the hose stucks
Rotate the hose a quarter to half turn on orient
the set of the hose to the direction change.
If the hose is rotated, once through the
Obstruction, turn the hose back to help prevent
Kinks.
10.4-2 Rotate the hose
When the hose is stuck in the line, try pulling hard
on the hose and releasing it quickly, that creates
a shock and loosens it up. Try to rotating the hose,
or turn off the jetter and pulling back the hose then
Turn on the jetter, or trun on the pulse and repeat
These operation several times.

11. Maintenance
To ensure efficient operation and longer life of your pressure jetter a routine maintenance schedule should be prepared and
followed. If the equipment is used in unusual conditions such as high-temperature or dusty conditions more frequent maintenance
checks will be required.
11.1 Engine:
Check the engine regularly, replace oil, clean spark plugs and maintain parts as required.
11.2 Pump Oil:
Change the pump oil regularly. Change the pump oil after the first 50 hours of work and successively every 200 hours.
In either case ensure that the oil is changed at least once a year. Check with your nearest Dealer for advice on the best Pump Oil
to use with this equipment if you are unsure.
11.3 Nozzle Unclogging:
If the nozzle becomes clogged with dirt and debris excessive pressure can build up. If the nozzle becomes partially clogged or
restricted the pump pressure will fluctuate and can become harmful and dangerous.
Clean the nozzle immediately and follow these instructions:
1. Shut-off the engine and turn off the hose reel cock, disconnect the water supply.
2. Remove the nozzle from the hose, remove any obstructions with the nozzle
cleaning tool and back flush with clean water.
3. Reassemble the nozzle onto the jetting hose.
4. Turn on the water supply, start the pressure jetter, and turn on the hose reel cock.
5. Set the pressure jetter into the high pressure setting to test.
11.4 Cleaning The Water Filter:
The water filter should be checked regularly and cleaned if necessary:
1. Remove the filter by grasping the end and removing it from the water
inlet on the pump.
2. Clean the filter by flushing it with water on both sides.
3. Re-insert the filter in the water inlet on the pump.
Before performing any maintenance be aware that the equipment should be completely shutdown,
depressurized and allowed to cool down. This will ensure that no injuries can be sustained by moving parts,
water pressure or hot surfaces.
Engine contains flammable fuel do not smoke near or work near naked flames while maintaining this
equipment. Please note: All repairs should be carried out by Dealer approved engineers. All replacement
parts should be supplied or recommended by the Dealer. Any unapproved repairs or modifications will
invalidate the warranty.
Avoid prolonged or repeated skin
contact with used motor oil.
Used motor oil has been shown to cause skin cancer in certain
laboratory animals. Thoroughly wash exposed areas with soap
and water.

11. Maintenance ( Continued)
11.5 High Pressure Hose:
Replace the high pressure hose when the hose
have any of the below circumstance:
1. Cover damaged.
2. Burst.
3. Bubbles/blisters.
4. Kinked/collapsed.
11.6 Cleaning the Fuel Tank Filter:
The fuel tank filter should be removed and cleaned after every 150 hours of running or every 3 months using an environmentally
-friendly water-based de-greasing agent. Refit when clean.

NOTE: BE CAREFUL with jetter hose against sharp edges Sharp edges can scrap, slice and generally
damage hose quickly. While hose is easily replaced, it pays to take care by buffering sharp edges with
tape, cardboard, etc., to maximize its useful life.
The high pressure stream of water can cut
through skin and its underlying tissues,
leading to serious injury and possible
amputation.
•Never repair high pressure hose. Replace
it.
•Replacement hose rating MUST exceed
maximum pressure rating of the unit
