5. Inspect the jetter nozzle orifices for any damage or
blockage. Blockages can be cleaned with a nozzle
cleaning tool. Use care not to enlarge nozzle orifices
while cleaning. Damaged nozzles or nozzles with
enlarged orifices can decrease jetter performance
and should be replaced.
6. Inspect the hoses, connectors and fittings for wear and
damage. If there are any kinks, cracks, breaks or
wear through the outer jacket of the hose or other
damage, do not use the hose. Damaged hoses can
burst or leak high pressure water and cause serious
injury. Replacement hoses and fitting should be rated
at or higher than the jetter pressure rating.
7. Inspect and maintain the engine per the engine oper-
ator’s manual.
8. Check engine fuel level
(Figure 4A)
. If needed, add
unleaded gasoline. See engine operator’s manual for
requirements. Use caution when handling gasoline.
Work in a well ventilated area. Never fill the tank while
unit is running, do not overfill tank and do not spill fuel.
Make sure tank cap is securely closed.
9. Check the oil level(s) in the pump and gear box
through the sight glass and add oil if needed
(see
Maintenance Instructions section)
. Inspect Engine
as directed in the engine operator’s manual.
Machine and Work Area Set-up
WARNING
Always wear safety glasses, gloves and other appro-
priate protective equipment when setting up your jet-
ter to protect against chemicals and bacteria on the
equipment. Rubber soled, non-slip shoes can help
prevent slipping on wet surfaces.
engines produce carbon monoxide, a colorless,
odorless poison gas. Breathing carbon monoxide
can cause nausea, fainting or death. do not start and
run engine in an enclosed area, even if doors and
windows are open. only operate outside.
Set-up the jetter and work area according to these
procedures to reduce the risk of injury from high
pressure water, chemical burns, infections, car-
bon monoxide and other causes, and prevent jetter
damage.
1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite. If
present, do not work in area until sources have
been identified and corrected. The machine is not
explosion proof and can cause sparks.
• Clear, level, stable dry place for machine and oper-
ator. If needed, remove the water from the work
area. Wood or other coverings may need to be put
down.
• Jetter location that is in a well ventilated outdoor
area. Do not place the jetter indoors, even with
doors and windows open. Jetter can be located
remotely from the point of use.
• Suitable water supply.
• Clear path to transport the jetter to the set up location.
2. Inspect the drain to be cleaned. If possible, deter-
mine the access point(s) to the drain, the size(s) and
length(s) of the drain, distance to tanks or mainlines,
the nature of the blockage, presence of drain cleaning
chemicals or other chemicals, etc. If chemicals are pre-
sent in the drain, it is important to understand the
specific safety measures required to work around
those chemicals. Contact the chemical manufacturer
for required information.
If needed, remove fixture (water closet, etc.) to allow
access to the drain. Do not feed the hose through a fix-
ture. This could damage the hose and the fixture.
3. Determine the correct equipment for the application.
See the Specifications section for information on the
jetter. Drain cleaners and jetters for other applica-
tions can be found by consulting the RIDGID Catalog,
on line at www.RIDGID.com/au/en.
4. Make sure all equipment has been properly inspect-
ed.
5. Evaluate the work area and determine if any barriers
are needed to keep bystanders away. Bystanders
can distract the operator. If working near traffic, erect
cones, signs or other barriers to alert drivers.
