MYTANA M20T / M20 / M30 Jetter USER MANUAL

-IMPORTANT NOTICE-

FOR YOUR SAFETY, AND TO ENABLE MAXIMUM USE AND EFFECTIVENESS

OF YOUR EQUIPMENT, READ AND UNDERSTAND THIS INSTRUCTION MANUAL

ENTIRELY BEFORE USING YOUR HIGHPRESSURE WATER JETTING UNIT!

FAILURE TO FOLLOW INSTRUCTIONS AND REGULATIONS CONTAINED IN

THIS MANUAL CAN RESULT IN SERIOUS INJURY TO THE OPERATOR AND/OR TO

ANYONE IN CLOSE PROXIMITY TO THE WORK AREA.

The Jetting Process

Water Jetting—also know as sewer jetting or hydro-jetting—uses a combination of water pressure and

water ow through a hose and nozzle to clean debris out of drain and/or sewer lines. Water jetting is

used to wash out clogs, potential blockages or to simply clean the walls of drains and sewer lines to

prevent future blockages.

uSewer jetting diers from normal pressure washing in two ways:

• 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 accompanying hose forward into the sewer line and also cleans the walls

of the pipe.

• Water pumps on sewer jetting equipment are modied to allow pulsation of water through the hose to the

nozzle. This pulsation creates a vibration or “wiggle” in the jetting hose that allows the hose to move through

a drain or sewer line with little resistance. Pulsating also reduces pressure and/or ow of the water, so most

pumps are equipped to turn pulsation on and o at will.

uSewer jetting diers from traditional “snaking” in that jetting is most eectively done from LOW end of a

clogged drain or sewer, but is also eective from the high-side.

• Traditionally, clogged pipes were opened from the high side using the aid of gravity and the downward ow of

water to clean. In the water jetting process, cleaning from the low side allows the operator to both see debris

coming downward and to take advantage of the water pressure and ow that is pointing toward the low end if

cleaning from the low side. NOTE that it is usually not practical or even possible to clean from the low side of a

drain or sewer line. Jetting is still eective from the high side.

Components of water jet machines: Water pump; hose reel; various sub-components that protect the pump and

the operator; various nozzles for various cleaning applications and situations. Larger jetters use a water storage tank

for additional water supply.

MYTANA M20T / M20 / M30 Jetter USER MANUAL

Pumps Remove “shipping” plug on top side of

pumps and replace with vented plug. This is very

important for the proper operation of the pumps.

Do not store or run the pumps on its side or at a

sharp angle, since oil can run out of the vent plug.

Keep bystanders or unauthorized persons away

Insist they keep a safe distance before operating

high pressure equipment!

Environment

• Use caution in conned or wet areas. Since you will

often be 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.

Always insert hose and nozzle into pipe opening and hold

onto hose before turning the machine on.

Changing hose and/or nozzle ALWAYS turn machine o

when changing nozzles, hoses or reels.

Never hold onto nozzle or point it at anyone with

machine turned on. High pressure water streams can

cause serious bodily harm.

Job Completion Always turn machine o before

disconnecting water supply. Running a water pump “dry”

will seriously damage the water pump.

Maintenance

• Keep machine clean and dry to maximize performance

and longevity.

• Follow maintenance schedules such as changing oil,

check for weak spots, slices or cuts in hose, keep inlet

screen clean, replace nozzles when worn.

• Keep antifreeze in hose and pump in freezing

temperatures.

• Additional maintenance details follow in this manual.

Common Sense Don’t operate equipment under the

inuence of drugs, alcohol or if taking medication that

alters alertness.

Electric machines

• Avoid electric shock! Before using your electric

machine, make sure that a properly grounded

outlet (three hole) is available. If one is not

available, use a three prong adapter making sure

to connect the green pigtail from the adapter to a

sure ground, such as a steel water pipe.

Never run your jetting machine 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.

• Use 12 gauge or heavier extension cords to power

the machine.

• Never spray motor or electrical connections directly

with a water stream.

• Avoid getting the electrical connections and

components wet.

Gas Jetters

• Always operate machine in well ventilated environ-

ment. Exhaust fumes can be potentially lethal to the

operator.

• Do not allow ame or sparks in the area of operation.

• Do not refuel engine when it is hot. Spilled gasoline

or gas vapor can ignite if it comes in contact with hot

engine.

• Be careful not to touch engine block or the manifold/

muer during operation. These areas will become

very hot during normal operation.

• Do not lay machine on its side or tilt it backwards

(other than wheeling it from place to place). This can

cause gas to leak out the cap vent.

uBecause the gas jetter is tilted back about 30°

for transport, do not ll the gas tank all the way.

Leave several inches of space between the gas

and the top of the tank to prevent gas from

leaking out.

Gas jetters that are ordered with an electric starter

package will have a battery attached. Batteries contain

sulfuric acid. Avoid direct skin contact. Wear protec-

tive gloves, clothing and eyewear when handling your

battery!

General

Applications

• General maintenance • Sharp turns, traps

• Ice, thick grease and/or sludge • Thorough cleaning of surface

MyTana nozzles are precision machined hardened stainless steel, Rated for use up to 4000 psi

Your jetter works via the proper blend of water pressure

and water volume: the more water that has to pass through

the restriction of a hose, the

less pressure you will have at

the nozzle end. To optimize

cleaning power, use the

shortest hose with the largest

inside diameter that you can.

The orices (holes) in the

nozzle aect pressure. Over

time, water pressure will

wear the orices in your

nozzle resulting in pressure

drop and reduced cleaning

eectiveness. Nozzles need to

be replaced as normal wear

occurs.

This chart is to provide a

general guideline. Each job

is dierent and will be best

served by your experience.

MYTANA M20T / M20 / M30 Jetter USER MANUAL

Pumps

Periodically change oil in pumps.

• Change oil after rst 30 hours of use for “break-in”

• After that, change every six months or at approximately

250 hours of use

• Recommended oil: General Pump (GP) Brand SAE 30W

Non-detergent

Do NOT run pump without water in it. This can damage

the cylinder walls, warp or crack the pump casing.

Do not use water more than 145°. This will damage seals.

Your pump is equipped with a thermal relief valve. However,

to optimize pump protection you should still avoid water (or

any pumped uid) that is too hot on the inlet side.

NEVER run pump if there is ice in pump or outlet hose.

To avoid freezing in the pump, run antifreeze through

pump and hose(s) if stored overnight in freezing tempera-

ture. (The same bottle of antifreeze can be recycled

numerous times. If it becomes discolored or diluted,

replace with new.)

uBest Care: If the jetting unit will be unused for a period

of time (more than several days), even in warm temper-

atures, we recommend running antifreeze through

pump and hose before storage. Antifreeze greatly

reduces the chance of rust, mineral deposits and other

contaminants damaging the pump during storage.

Additional Components

Thermal Relief Valve

As stated earlier, water temperatures in excess of 145° can

damage the pump seals. The thermal relief valve provides

protection when the pump goes into “bypass” meaning the

pump is running but no water is being pushed

through the hose.

Pulse-abler

The stem and handle extending from one cylinder

of each water pump enables pulsation of the water

stream through the hose and nozzle. By turning the

pulse-abler handle clockwise (or right), you temporarily

disable one valve of the pump. This creates pulsation

or vibration in the hose, allowing the hose to “wiggle”

through tight bends quickly and easily. Turn the pulse-

abler handle left again to “enable” the pump again.

uDisabling a valve also reduces cleaning

power, so use the pulsation only as needed

to arrive at an obstruction or to retrieve

a stuck hose.

Pressure Regulator/Unloader

The regulator/unloader both regulates the pressure and

relieves pressure on the pump while in bypass. The regulator

knob is located at the pump. It allows you to adjust pressure

during operation.

Regulation is needed because greater pressure requires more

power (meaning amperage in electric models) from the power

source. Therefore you should start the electric units with as

little pressure as possible (on 15Amp circuits, back o to 1K -

1.2K PSI). This reduces the load on the motors at start up and

avoids tripping circuit breakers.

After startup, gradually increase pressure to the levels below.

uOn GAS powered units, the speed of the motor directly

aects the amount of pressure. Adjust to a constant

motor speed before adjusting pressure regulator.

Water Inlet and Filter

The water inlet has a lter to prevent debris from running

through your pump.

• Run water through the source hose into an open drain

or bucket to ush debris out of faucet and hose — make

sure the water is running clean and clear BEFORE

attaching source hose to the pump

• Recheck the inlet lter before each use to make sure

there is no obstruction.

Operation Instructions

1. Attach garden hose (minimum of 5/8” diameter) to

water faucet. Run water through the hose into an open

drain or bucket to ush debris out of faucet & hose

before connecting to pump. Shut water

o again when water runs clear.

2. Attach other end (male end) of garden

hose to water inlet valve at pump.

3. Connect jetter hose to reel

4. Attach nozzle to end of hose. Finger

tighten, do not over tighten.

5. Mark the hose approximately 10 feet back from

nozzle with electrical tape. Use this tape as a marker

to shut o machine before retrieving all the line out

of the drain pipe.

6. Open water intake.

7. Open water faucet again to prime pump. An equal

amount of water should pass through the orices of

the nozzle.

8. Push jetter hose into drain up to the marker when

possible (minimally several feet).

9. Make sure your extension cord is plugged into a

properly grounded 110 volt receptacle.

10. Start Motor/Engine

Electric Units Only

• Make sure motor is plugged into a properly

grounded outlet

• Start jetter motor by ipping switch into the

“on” position.

• Electric jetter owners, move on to step 11

Gasoline Engine Unit With Electric Start

• Turn the fuel valve to the “on” position (by moving

lever to the right)

• Move choke lever to the “choke”

(or close) position to the left

• Make sure throttle is in the “run”

position, approximately halfway

between “STOP” and “FAST”

• Turn key to “start” and start engine

• Gradually move choke to the open position

• Move throttle to desired speed

uNOTE: Since your gas engine speed is variable,

be aware that low rpm equals low pressure at

the pump. Conversely, high rpm equals high

pressure. For normal operation, do not exceed the

recommended 3000 psi (with the larger 3/8” hose).

When running smaller trap (1/8”) hose, manually

adjust pressure setting lower to maximum of 1500

PSI. Like the electric models, you may turn the

pressure regulator to desired pressure.

11. Adjust pressure with pressure regulator knob, turning

right to increase pressure, left to decrease. Note: See

recommended max. pressure settings listed on page 5.

12. Start jetting, using pulsation only if needed to promote

forward motion of nozzle and hose.

Pre Operation Checklist

• Check for adequate

water supply. Use no

smaller than 5/8” garden

hose for supply to pump

• Make sure water inlet

lter is clean.

• Check ground fault

interrupter on electric

models. Test and reset.

• Check uid levels: Oil in

pumps, oil & gas in gas

powered unit.

• Select nozzle and make

sure orices are not

blocked or worn to

excess

• Check hose for wear or

kinks

• Check hose reel and all

connections

Some newer M30 models are

equipped with Automatic Choke

and Throttle Down (look for label

when you unpack the machine).

These steps are not necessary.

Care Tips

Never let pump run dry!! Pump cavitation can occur in

only a few seconds of running dry.

Avoid running anything abrasive through pump

Abrasive materials will damage pump components,

resulting in total malfunction or, minimally, loss of pressure

capability.

Anti Freeze Procedure If you know there will be a period

of several days when the jetter will be idle OR if the jetter

is stored in potentially freezing weather, make sure to run

antifreeze into pump and hose as part of your shut down

procedure. Simply insert a short length of garden hose into

a gallon of antifreeze, turn on pump an run until you see

antifreeze coming out of the nozzle end of the hose. At next

use of jetter, you can recover most of that antifreeze when

you hook up to your water source. Antifreeze can be used

multiple times. However if it gets to diluted (more than 50%

water) or if there is any discoloration, discard that antifreeze

and replace with new.

Be careful with jetter hose against sharp edges

Sharp edges can scrap, slice and generally damage hose

quickly. While hose is easily replaced, it pays to take care

by buering sharp edges with tape, cardboard, etc., to

maximize its useful life. MyTana has a TigerTail that helps

protect your hose. See MyTana.com for details.

Do not use Pulse-Abler more than necessary This device

is what enables high-pressure cleaning through multiple

turns in sink and sewer lines. However, the Pulse-Abler also

creates extreme vibration and faster wear on the pump. So,

use as needed, but do not use if a blockage or sewer line

conguration does not require it.

Helpful Operating Hints

• Tight bends and certain blockages are often more

easily negotiated by rotating or twisting jetter hose

at drain opening. Once you are through that area,

pull back and pass through several times to ensure

cleaning. Once you have opened the blockage(s),

pull hose back very slowly to provide maximum

cleaning to wall of pipe.

• When operating from the high end to low end (most

common) shut o the water ow ball valve on the reel

occasionally. This will allow debris to get ahead of the

nozzle and ush it down the pipe.

• Grease and Ice Blockages Warm water is eective

in cleaning grease and ice blockages. A cold-hot mix

from the tap is adequate. However, do not exceed 145

degrees Fahrenheit. Hotter water can damage seals in

your pump.

Shutting Down

1. When completing pass through drain, watch for tape

marker on hose as you pull the hose out.

2. Reduce pressure gradually with pressure regulator

knob until pressure gauge is at zero.

3. Stop the jetter motor/engine

Electric Models

• Move switch to “o” position

• Unplug extension cord from receptacle

Gasoline Models

• Move throttle lever all the way to the right

(slowest setting)

• Turn the key to the “o” position

• Turn the fuel valve to the “o” position

4. Continue to run water through pump and hose for

30 to 60 seconds.

5. Close water faucet and disconnect garden hose from

spigot.

6. Close water inlet valve. Disconnect garden hose from

jetter.

7. Pull remaining jetter hose from drain line.

8. Remove nozzle if you chose.

9. Store jetter hose properly on reel or in a coil to avoid

damage to hose.
