4. Remove the plug in gear box and replace with
dipstick/breather cap. Check the gear box oil level.
If low fi ll with 90W gear lube.
To start the gasoline engine
Manual start:
• Turn the engine switch to the ON position.
• Pull the starter grip until resistance is felt, then pull
briskly.
Electric start:
• Insert the key into the ignition and turn to the ON
position.
• Turn the key to the start position to start engine.
Release key after the engine is started.
NOTE: electric start engines can also be started manually:
make sure the ignition key is turned to the ON position.
Pull the starter grip until resistance is felt, then pull briskly.
As the engine warms up, gradually move the choke lever
to the open position and adjust the throttle level for the
desired engine speed.
NOTE: for further details on engine operation, see the
enclosed Honda owner's manual.
Before operating jetter
1. Connect the quick coupling fi tting to the water
supply hose. Connect water supply hose to the
jetter inlet and close the inlet supply valve (fi gure
6).
2. Connect the other end of the water supply hose
to the water faucet and turn the tap on. Make sure
there are no kinks or unnecessary bends in the
supply hose and that the water fl ow is at least the
fl ow rate of the machine.
3. Connect a jetter hose to the jetter's outlet quick
coupling on the end of the connection hose or if
a hose reel is used; attach connection hose to plug
fi tting on hose reel.
4. Insert jetter hose 15-20 cm into drain without a
jetter nozzle.
5. Open the inlet supply valve and run water through
the jetter and hoses.
6. Continue to run water through the jetter until all air
has been purged.
7. Close the inlet supply valve.
8. Attach a jetter nozzle to the jet hose. Hand tighten
for a snug fi t. Insert the jet hose into the line several
feet.

NOTE:
• KJ-1590 II: If 16 Amps is not available decrease the
pressure to decrease the current draw (fi gure 7). At
80 bar the machine uses 16 A (no extension cord
used), at 90 bar the machine uses 20 A. Using an
extension cord increases the need for Amps.
• KJ-1590 II: Make sure there are no other users on
the same electric supply.
• KJ-1590 II: The thickness of an electric extension
cable has to be 2.5mm≤ and has to be rolled out
entirely. The rule of thumb is you will loose 8 bar
pressure per 10m extension cord.
• You can also use a water tank to suck water out.
Please take into account a drop in the pressure.
First start the motor to let the air out of the hose
(1-2 minutes). The tank can be maximum at 1m
below the machine.
• Make sure enough water fl ow is available the reach
the pressure rating. For KJ-1590 II and KJ-3000 it's
15l/min. For KJ-2200 9l/min. A too low water fl ow
results into a shocking water beam and/or pressure
loss.
Figure 7: To regulate the pressure
• KJ-1590 II: put the pressure to minimum when you
stop the machine. When you start the machine,
make sure the pressure valve is put to minimum to
limit the current draw when starting up.
Jetter operation

Normal jetting

1. For normal jetting, turn the pulse actuator to the
OFF position and guide the hose into the line by
hand (fi gure 8).
2. When the jetter nozzle encounters a bend, its
advance will usually slow or stop. The jetter hose
has a slight bend or SET to it. The reverse thrust of
the nozzle will advance the jetter hose, but it is also
necessary to manually feed and rotate the jetter
hose to WORK THE SET around the bend.
3. If the hose won't advance, pull back on the hose
and rotate the hose a quarter to a half turn so the
set will align itself with the bend. Then advance the
hose forward.

KJ-3000), right (KJ-1590 II)
Using the pulse mode to negotiate
bends and traps
In some cases simply rotating the hose will not be enough
to negotiate a bend or a trap. In these instances, it will be
necessary to induce some pulse action. In the pulse mode,
