KJ-3000 Water Jetter Machine
Machine and Work Area Set-Up
WARNING
To prevent serious injury, proper set-up of the
machine and work area is required. The following
procedures should be followed to set-up the ma-
chine:
1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite.
• Adequate ventilation for engine exhaust.
Exhaust contains poisonous carbon mon-
WARNING
oxide gas. Exposure may cause loss of consciousness
and may lead to death.
• Water supply
NOTE! If a connection is made to a potable water sys-
tem, the system should be protected against
backflow in accordance with all local codes and
ordinances.
2. Connect the quick coupling fitting to the water supply
hose. Connect water supply hose to the jetter inlet
and close the inlet supply valve (Figure 4).
Figure 4 – Connect water supply hose to jetter. Close
inlet supply valve (shown in CLOSED position)
3. Connect the other end of the water supply hose to the
water faucet and turn the faucet ON. Make sure
there are no kinks or unnecessary bends in the sup-
ply hose.

Hot water improves the jetter's performance,
CAUTION
particularly when clearing grease blockages. Limit water
temperature to below 140°F.
4. Make sure the hose reel's connection hose is at-
tached to the jetter's outlet quick coupling (Figure 2).
• If a separate hose reel is used, attach hose to jet-
ter's outlet quick coupling as shown in Figure 2.
• If necessary, use trap hose. (Refer to Jetter Hose
Selection Chart).
5. Insert jetter hose 6" – 8" into drain without a jetter
nozzle.
6. Open the inlet supply valve and run water through the
jetter and hoses.
7. Continue to run water through the jetter until all air has
been purged.
8. Close the inlet supply valve.
9. Attach a jetter nozzle to the jet hose. (Refer to Jetter
Nozzle Selection Chart). Hand-tighten for a snug fit.
Over-tightening can interfere with water flow through
the nozzle orifices causing reduced flow and poor per-
formance.
WARNING
drain while pressurized. Conspicuously mark the hose at
a distance of 24" (60 cm) from nozzle to indicate the lo-
cation of the nozzle.
10. Insert the jet hose into the line several feet.
11. Open the inlet supply valve and verify that water
flows freely through the nozzle by pulling jetter hose
back towards inlet slowly.
