Figure 3 – Connect jetter hose to jetter
Nozzles should not be removed from the
drain while pressurized. Mark the hose at a distance of 24″
(60cm) from nozzle to indicate the location of the nozzle.
11. Insert the jet hose into the line several feet.
12. Open the inlet supply valve and verify that water
flows freely through the nozzle.
13. Plug the Jetter into the electrical outlet making sure to
position the power cord along the clear path selected
earlier. If the power cord does not reach the outlet,
use an extension cord in good condition.
To avoid electrical shock and electrical
fires, never use an extension cord that is damaged or
does not meet the following requirements:
• The cord has a three-prong plug similar to shown in
Electrical Safety section.
• The cord is rated as “W” or “W-A” if being used out-
doors.
• The cord has sufficient wire thickness (12 AWG). If
the wire thickness is too small, the cord may over-
heat, melting the cord’s insulation or causing nearby
objects to ignite.
To reduce risk of electrical shock, keep all
electrical connections dry and off the ground. Do not
touch plug with wet hands. Test the Ground Fault Circuit
Interrupter (GFCI) provided with the electric cord to insure
it is operating correctly. When test button is pushed in, the
indicator light should go off. Reactivate by pushing the
reset button in. If indicator light goes on, the machine is
ready to use. If the GFCI does not function correctly, do
not use the machine.

Features three reverse jet thrusts for maximum propulsion to jet long distances. Use
this nozzle for most applications.
Uses three jet thrusters in reverse plus one jet pointed forward to penetrate solid grease
or sludge blockages. The forward jet blasts a small hole in the blockage for the noz-
zle to follow. It is also very effective when jetting ice blockages.
Use the drop head to help negotiate difficult bends.
Use spinner nozzle to clean grease and similar blockages.
