PG 2 MyTana M20T / M20 JETTER User Manual
Safety First!
Instructions and Precautions
Environment
• Use caution in conned or wet areas. When working
directly through clean outs or openings into sewers
(non-trapped openings) make sure that there is
adequate ventilation into the work area.
• Do not operate machine in areas where
ammable gases or liquids are present.
Keep bystanders or unauthorized persons away
Insist they keep a safe distance before operating
high pressure equipment.
• Never hold on to nozzle or point it at anyone with
machine turned on. High pressure water streams can
cause serious bodily harm.
Never run your jetter without a properly grounded
electrical supply and hookup. This is electric equipment
in a wet environment. Every precaution should be taken
when water and electricity are in close proximity.
• If an extension cord is needed beyond the built-in 25’
cord, use 12gauge or heavier to power the M20
• Avoid getting the electrical connections and
components wet.
Shut the machine down:
• When changing nozzles, hose or reels.
• Before disconnecting water supply. Running a water
pump “dry” will seriously damage the water pump.
• If it will be unattended.
• If machine fails to run properly.
Maintenance Follow antifreeze and maintenance
procedures as outlined in this manual.
Common Sense Don’t operate equipment under the
inuence of drugs, alcohol or if taking medication that
alters alertness.
• NEVER run ammable liquids or toxic chemicals (such as
insecticide or weed killer), acids or hard caustics (such as
lye) through the pump. Only water!
• NEVER use chemicals or agents that are not compatible
with the PVC (polyvinyl chloride) or neoprene covering of
the hose.
• NEVER clean the machine using its own spray.
High-pressure spray could damage components.
Keep all labels, decals, warnings, cautions, and instructions
with machine. For new decals or labels contact Mytana.
The Jetting Process
Sewer jetting (or hydro-jetting) uses a combination of water
pressure (psi) and ow (gpm) through a hose and nozzle to
ush debris out of drains or sewer lines.
Water jetting is used to penetrate and wash out clogs or ice,
potential blockages or to simply clean the walls of drains
and sewer lines to prevent future blockages.
Sewer jetting diers from normal pressure washing:
• Sewer jet nozzles direct the ow of water back toward
the operator at a 20 to 45 degree angle. This backward
stream propels the sewer nozzle and hose forward into
the sewer line and also cleans the walls of the pipe.
• Jetting pumps deliver more ow and controlled
pressure to clear tough blockages.
Components of hydro jetters: Water pump, motor, hose
reel; various sub-components that protect the pump and
the operator; various nozzles for various cleaning applica-
tions and situations. Larger jetters use a water storage tank
for water supply buer.

jetters. Many are available to purchase
