Page: 9 / 20

PREPARATION FOR USE
1. Refer to page 8 for start-up procedure.
2. Run out a significant length of jetting hose
from the hose reel.
3. Push at least 3-metres of jetting hose through
the hole located in the centre of the safety
plate.
4. Attach the selected drain cleaning nozzle to the
end of the jetting hose. Please be sure that the
nozzle is
fully snapped into position .
5. Place at least 1-metre of the hose length down
the drain, using the hose markings as an
accurate guide.
6. Proceed to cover the entrance to the drain with
the safety plate.
7. Turn on the ball valve in order to activate the
high-pressure jet nozzle.
8. Ease the hose down the drain, twist the hose to
aid the nozzle in negotiating bends and turns.
The nozzle will create a gentle pulling action
against the hose. If it becomes stuck, a sharp
tug should free it up.
