CONTROL PANEL OPERATION
The Control Box consists of a base unit with a tethered Remote Box to allow the operator to easily move around if desired. There are three
levers on the Remote Box:
DUMP, HOSE ROTATE
, and
HOSE FEED
. All three levers are spring loaded to return to the center, OFF position.
The
DUMP
lever, when pushed forward, provides air to the ¼” push-connect fitting that is intended to supply air to a pneumatic dump valve to
divert high-pressure water to the tool.
When the HOSE FEED lever is pushed forward, it drives the hose forward into the pipe. Drum rotation is automatically coupled with the switch
when pushed forward. This rotation is essential to navigating around bends. It also keeps the hose expanded towards the outside of the drum
so that it doesn’t coil inward and potentially fall out of the drum. When the
HOSE FEED lever is pulled backward, it retracts the hose from the
pipe. Rotation of the drum is not coupled; the hose naturally expands in the drum when retracting.
The
HOSE ROTATE
lever activates the drum rotation only. Either direction of the switch always activates rotation in the same direction.
Rotation is used in a couple scenarios:
• When driving forward into a pipe – and the hose is already around several bends – the tool will drive into an elbow and see an increase
in rotational resistance. Drum rotation will strain as curvature builds up in the hose. Instead of trying to keep forcing the tool forward, using
rotation only will slowly relax the built up hose curvature, which also slowly drives the tool forward through the bend.
• During hose retraction, it’s ideal to reverse out of the pipe without rotation; this will reduce wear on the hose and rollers. Occasionally, the
tool can get hung up at a bend, especially if it is far into a pipe. Temporarily activating rotation will get the tool moving again.
Forward and Reverse HOSE FEED speeds can be adjusted independently using the flow control valves on the base of the control box. Slow
speeds are required to go forward through bends. Faster speeds are acceptable during retraction.
When using the Navigator and the hose is being driven forward in a pipe, the operator should watch the inside of the drum area, specifically
where the hose is entering the compound elbow. The amount of force this section of hose can take is the machine’s limiting factor. With a lot
of elbows in a pipe, there’s going to be a lot of torsional resistance and a lot of stress on the hose. Too much stress and the hose would buckle
and tie itself into a knot. To help prevent this, a fixed-pressure regulator in the control box limits the air pressure available to the rotation motor.

STORAGE, TRANSPORTATION, AND HANDLING
When storing the unit, use compressed air to blow out the air lines
to remove debris and moisture. Use mild soapy water to clean the
machine in order to remove corrosive materials.
The Navigator (NAV-100) can be easily transported by lifting the handle
on the base assembly and wheeling it to its next location.
