cord is damaged, do not use the jetter until the cord
has been replaced.
When replacing cord, use only identical
WARNING
replacement parts that includes GFCI protection.
4. Check inlet filter screen for debris that can restrict
water flow into the pump resulting in poor perfor-
mance. If filter screen is dirty or clogged, remove,
clean and replace.
5. Use accessories that are designed for your Jetter
and meet the needs of your application. The correct
accessories allow you to do the job successfully
and safely. Accessories suitable for use with other
equipment may be hazardous when used with this
machine.
6. Clean any oil, grease or dirt from all equipment han-
dles and controls. This reduces the risk of injury due
to a tool or control slipping from your grip.
7. Check the jetter nozzle orifices for debris. If an orifice
is blocked, use nozzle cleaning tool to clear and re-
move debris.
8. Inspect hoses for wear and damage. Hoses should
be replaced when they become damaged.
WARNING Damaged hoses can burst causing seri-
ous injury. Only use hoses whose pressure rating meets
or exceeds that of the jetter.

Machine and Work Area Set-Up

WARNING
To prevent serious injury, proper set-up of the ma-
chine and work area is required. The following pro-
cedures should be followed to set-up the machine:
1. Check work area for:
• Adequate lighting.
• No flammable liquids, vapors or dust that may ignite.
• 20 amp grounded electrical outlet.
• Clear path to the electrical outlet that does not
contain any sources of heat or oil, sharp edges or
moving parts that may damage electrical cord.
• Dry place for machine and operator. Do not use
the machine while standing in water.
• 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 2)
Figure 2 – 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. Connect a jetter hose to the jetter's outlet quick cou-
pling on the end of the connection hose (Figure 3).
(Refer to Jetter Hose Selection Chart)
5. If a hose reel is used, attach connection hose to
plug fitting on hose reel.
6. Insert jetter hose 6" – 8" into drain without a jetter
nozzle.
7. Open the inlet supply valve and run water through the
jetter and hoses with unit OFF.
8. Continue to run water through the jetter until all air has
been purged.
9. Close the inlet supply valve.
NOTE! Both the KJ-1350's and KJ-1750 Jetters have
check valves for back flow prevention.
10. 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.
