6. If needed, place protective covers in the work area.
The drain cleaning process can be messy.
7 . Take the jetter to the well-ventilated outdoor work
area along the clear path. See Transportation Section.
Be aware of possible slip hazards. Wear appropriate
footwear to help prevent slips.

Water Supply

Run a hose from the water source to the jetter water inlet.
Use the largest diameter, shortest length hose possible. A
3/4" I.D. inlet hose is the minimum recommended size. An
appropriate backflow prevention device should be used to
comply with all local codes and ordinances.
Dirt and debris in the water supply can cause excess
pump wear, clog the jetter filter, nozzles and reduce per-
formance. Do not use water from ponds, lakes or other
sources that may be contaminated.
Fill the jetter water tank prior to starting the jetter.
The tank is equipped with a:
• Low water level shut-off to prevent pump damage
from insufficient water. This will shut OFF the engine
when the tank water level falls below a predeter-
mined level.
• Float valve to shut-off inlet water when the tank is full,
preventing water spillage through the tank vent.
By removing two screws, the top of the tank can be
removed for inspection or tank cleaning (Figure 6).

Warm water can be used for improved cleaning. Do not
use water hotter than 60°C this can cause pump and/or
float valve damage. When using warm water, use appro-
priate personal protective equipment to reduce the risk of
burns.
When using in cold weather, use precautions to prevent
water from freezing in the pump. This can damage the
pump

drain Preparation

If working through a manhole, storm grate or other large
access, use pipe and fittings to create a guide for the
jetter hose from the drain opening to operation point. This
will prevent the jetter hose from whipping around in the
access and protect the hose from damage (Figure7 ).

Point

Hose Set-up

Use care when routing jetter hoses. Routing hoses over
rough surfaces, sharp edges, crossing hoses, etc. can
damage the hose jacket. Keeping the jetter hose on the
reel(s) will help to minimize hose damage.
The KJ-5000 is equipped with two hose reels, a primary
reel mounted to the jetter frame and the remote reel
which has a separate base. Typically the primary reel is
equipped with larger hose suitable for jetting larger diam-
eter drains or supplying water to the remote reel. The
remote reel is typically equipped with smaller hose used for
jetting smaller diameter drains.
1. Select a jetter hose size appropriate for the drain
being cleaned. See Jetter Hose Selection Chart.
2. Locate the desired hose reel (primary or remote) for
jetting within 1 meter of the drain opening. Do not allow
excessive amounts of hose outside of the drain to pre-
vent hose damage. If the hose reel cannot be placed
within 1 meter of the drain opening, extend the drain
opening back to the hose reel with similar sized pipe
and fittings (Figure 7).
