PRIME THE PUMP
Every MotorScrubber Jet is thoroughly tested in our factory
before dispatch. It is possible during storage and transport
an airlock will have developed in the pumping system. To
release any airlocks present you must complete the priming
steps below before the Jet can be used. The initial prime
takes roughly 2 minutes to complete.
2 MINUTES
HOW TO PRIME THE PUMP
1. Put the back pack on.
2. Fill the bottle with clean water and
securely fasten the cap.
3. Connect the water and electrical cables,
see page 7 for instructions.
4. Hold down the blue switch and continue
to do so until water is continuously
spraying from the jet. The pump will go
through the following stages:
• Air - trapped air starts to work through
the system. High pitch pump noise
with drips from the jet.
• Water - the pump will start to take
water into the system. Pump noise
deepens with weak spray from the jet.
• Primed - The pump will make a deep
continuous hum, you will see high
pressure water at the jet.
5. When you request water it should be an
instant start / stop of water flow with a
constant high pressure flow.
The first prime can take up to 2 minutes
to complete. Further primes will take
approximately 30 seconds, a prime will need
to be carried out before each use.
Visit www.motorscrubberclean.com/support
for an instructional video if you are unsure
you have primed the pump correctly.
This process should also be used to rinse out
chemical after every use.

PREPARING THE CHEMICAL
1. Fill the bottle with clean water, no
more than 35°C (95°F), to the neck of
the bottle.
2. Slide the chemical cartridge into
the top of the filled bottle until the
cartridge stops.
3. Insert the tube with through the
cartridge.
4. Screw the cap straight down into
place, being careful not to cross
thread it. You will hear a small pop,
the cartridge is now pierced and the
chemical released.
5. Gently shake the bottle to fully
disperse the chemical into the water.
6. Slip the bottle into the bottle pouch on
the harness. The solution is now ready
to use.
Unused solution can be stored in the bottle
with a solid screw cap for up to 4 weeks.
Additional bottles with solid caps can be
purchased for storing dierent chemicals.

• When using MotorScrubber make sure the brush or pad is flat to the floor, this will ensure
smooth operation of the machine and an optimal clean.
• The Jet is a low water use cleaning machine, only a small amount of detergent is
required to wet and clean the floor, allow the brush and powerful scrubbing action to
release the dirt. The 1L solution capacity can eciently clean up to 40m2.
• Do not to use water hotter than 35°C (95°F), this can damage the valves and pump.
• When the solution bottle is nearly empty look for the jet to stop spraying. Do not operate
the pump as this will create an airlock. Simply re-fill with chemical and prime the pump.
• After every use you need to flush the pumping system. To do this fill the bottle with
clean water and hold down the blue switch for 60 seconds. Foam will spray from the jet
and you will see this change to clean water. This is a vital step as the delicate valves and
small pipes can become damaged or clogged with chemical if left to sit for a long time.
To maintain your warranty this step must be carried out.
• As a manufacturer to guarantee Jet from defects we have thoroughly tested our quality
range of chemicals and approved them for use with our machine.
• It is impossible for us to control every type of chemical that could be used through
the machine. If you decide to use your own none approved chemical which causes
damage to any of the components this will void your warranty. It is possible to use other
detergents through the MotorScrubber Jet, however, they must be approved through
your Countries MotorScrubber partner.
• Scrub with straight, light strokes. You do not have to exert pressure through the head,
MotorScrubber will do the work for you.
• DO NOT USE MOTORSCRUBBER WITH FLAMMABLE CLEANING FLUIDS.
• AUTOMATIC SHUT-OFF: MotorScrubber is equipped with a self-resetting circuit breaker
to prevent damage to the motor. If the unit is stalled, the circuit breaker will interrupt
the electrical power from your 12-volt battery. Remove MotorScrubber from the work
surface. The circuit breaker will re-set in 6 to 10 seconds. Resume using MotorScrubber.
REMOVING DIRTY SLURRY
There are many ways to remove dirty slurry after cleaning, the most eective ways are:
1. Coming soon: MotorScrubber can be equipped with a
suction head which can be connected to a wet vac for slurry
pickup. Estimated end of 2017.
2. Squeegee: Many hard floor areas have a drain in the floor.
Dry and remove the slurry with a floor squeegee into the
drain.
3. Microfibre: Use our MS1053 microfibre pad to absorb the
slurry, carry multiples for heavy use. Our microfibre pads
can be machine washed up to 400 times.
4. Flat mop: Use a flat mop with microfibre to absorb the slurry.

UNDERWATER USE
• Because its motor head can be fully-immersed in water,
the MotorScrubber is ideal for many underwater cleaning
tasks. One of the more popular uses of the MotorScrubber
is cleaning the “scum line” above the water level in
swimming pools, spas, boats, etc.
• mmersing the head for long periods of time could eect
its water-proofing seals due to the eects of prolonged
heating and cooling. The seals could contract and allow
water to make direct contact with the motor, which would
cause a motor failure. Guidelines need to be followed to
avoid this.
• The seals should be inspected once a month to check
for signs of corrosion that would compromise its water
tightness. If the unit is used underwater on a regular basis
an internal inspection of the head is also required each
month by a competent technician, this is to check for water
ingress.
WE RECOMMEND NOT USING THE MOTORSCRUBBER
FULLY SUBMERGED IN WATER FOR MORE THAN
2 MINUTES CONTINUOUSLY. MOTORSCRUBBER
SHOULD THEN BE REMOVED AND ALLOWED TO COOL
FOR 5 MINUTES.
• Waterline cleaning where MotorScrubber is half in and half
out of the water has no limitations.
• Regular underwater usage will reduce the lifetime of
the head unit. MS4000 complete motor head can be
purchased and replaced when required. 1 year is the
suggested life of regular underwater use.
Submerge
up to 25cm
away from
the switches
• The battery should be charged before using your MotorScrubber, after each use, and if
unused for 4 months.
• When charging the machine the red light will show, when the battery is fully charged the
light will show green. A full charge from flat will take approximately 8 hours.
• Connect the coil cord into the charger (See page 4, Point 8 to 11) and then plug the
charger directly into a 120 VAC/60HZ or 240 VAC electrical outlet or use an adapter
or a charger made for the AC source being used. (Do not use an extension cord). After
charging, disconnect the charger from the AC outlet and (IMPORTANT) disconnect the
charger from the battery.
• MotorScrubber uses a rechargeable sealed lead-acid battery. Non-spillable.
• Capacity: 12-volt, 7.0 amp-hour
• Depending upon the average depth of discharge, over a thousand discharge/charge
cycles can be expected.

IMPORTANT SAFETY INSTRUCTIONS
15
IS YOUR MACHINE NOT TURNING ON?
• If your MotorScrubber is not turning on or is turning slowly check the battery terminals
are connected properly and motor to handle plugs are connected securely.
• Next, using a voltmeter, simply open the battery pack, disconnect the two leads at the
battery, and touch the voltmeter probes to the terminals accordingly. A satisfactory
reading would be approximately 11.5 to 13 volts.
IS YOUR MACHINE NOT SPRAYING?
If the machine is not spraying after priming the pump (see page 8) complete the following
steps:
1. Can you hear the pump running when the blue pump switch is pressed, with the machine
connected to the electrics? If yes continue with the following steps. If you cannot hear
the pump please contact the seller.
2. Is the water bottle filled? If no, fill the water bottle and prime the pump (see page 8). If
the water bottle is filled continue below.
3. Does the water filter look clear? If blocked, replace the filter. If yes, continue below.
4. Check that the check valves (Page 4 Position 9 and Page 5 Position 8) are in the right
direction. On each check valve there is a small arrow, this should be pointing in the
direction of the water flow towards the head of the machine. If they are not, remove and
re-fit. If they are continue below.
5. Check the pump inlet and outlet connections are as tight as possible, air could be
sucked in. If they are firmly in place with no obvious point of entry for air to get through
please contact the seller.
