Brush identification

Thisis applicable whenthecustomerhasmore than onesetofbrushesof same type.
Example: 2 ormoresetsof StandardBrush

Customersmaynot interested to use samebrushesinBedroom / Kitchen / germfree
area which is already been used in other areas like Corridor / Bathroom / Oil or
chemical deposited areas. It is difficult for the customers to identify the particular
brush which isused incertain area. To make this easy,Brush buttons of colors RED,
BLUE,WHITE and YELLOW are packedwiththe machine. Customers shallplug the
buttons on the hole provided in the brush as shown. This helps the customer to
identifythe particularbrushbykeepingthe button (color)asreference.

Bypressing the pedal lightly withyour foot, pull back the handle a little tostart the motor.The
brushes and the drum starts rotating. Pulling the handle further without pressing the pedal,
lowersthemachine and engages therotatingbrushesontothe floor.Tostop working, take the
handleto the verticalposition.

By pulling, the liquid discharge control handle up, the cleaning liquid is made to spray on the
floor. The spraying stops once the liquid discharge control handle is released.

Brush contact with the floor is adjustable in 4 steps, contact is MINIMUM when the knob is
fullydownandMAXIMUM when it is fully raised. Thishelpsyou to compensate for the wear
ofbrushes and also to control the scrubbing effect.Ifthere is no machine movement,when
the handle lower down fully (working mode), change the knob position to one step up.

In the event of motor getting overloaded due to improper power supply or unexpected
obstruction to the brush/drum rotation, the over load protector trips and protects the motor
fromdamage.Ifthishappens,identifythecause,correctitand,resettheprotectorbuttonafter
minimum30seconds from tripping bypressingthe over load protector manuallyandcontinue
working.

SlidethisknobtoTOPposition to operate the machine. Slide this knob to BOTTOM position to

Care of the machine

3.Stopthe liquiddischargeapproximately onefoot beforethe end
offorward motion. continue to move forward uptothe wall without
pullingthe pullhandle .

Sprayangle / area canbe controlled by the user according totheir
requirements. It also prevents water / solutions sprayed in the
cleaned area. Spray angle of the solution is made to adjust using
the serrations provided in the nozzle and the nozzle holder.
Nozzle can be rotated about 28 degrees either clockwise or
counterclockwise @the increment of4degree (Fig-iv).

4. Pull the machine backwards in the same track, but without
discharging any liquid. When you are reaching the starting point,
change the track and repeat steps 2 through 4. When you are
changing the track allow some overlap with the cleaned area. In
case of large halls takeaU-turn and move forward. If quick drying
is desired, move on the same track, without discharging the liquid
(Fig-v)

5. When the dirty water tank is full, lift and pull the tank out of the
machine (Fig vi). Empty the tank and wash it in running water or
dip it in a bucket of water (Fig-vii). Clean the blades and push the
tankintoitsplace.

1.Move the Transport/ Working mode control knob to BOTTOM
(Transport)position(Fig-viii).

2. Disconnect the power supply by unplugging the electrical plug
andwind thecable overcableholders inthehandle.

3.Pull outthe dirtywatertank andwashit completely.

5.Remove thebrushes bypushingthe brushshaftout(Fig-ix).

6. Wash the brushes either by dipping in a bucket/sink or in
runningwater (Fig-x).

7. Turn the machine sideways and wipe clean the conveyor and
machinebody witha dampcloth(Fig-xi).

8. Re-install the brushes after washing. It is easier to push the

Upkeep of your PORT A SCRUB

Togetthemaximum life ofthemachineensurethe following.

Regularlyinspect sheath, plugandcordanchoragefor damage orlooseconnection.

For maximum life wash the brushes regularly.Ensure machine is in Transportmode when not in use. Store
additionalbrushes in a verticalposition to avoidbending of bristles. Checkfor permanent bending ofbristles
in a particular direction. This may occur if the machine is operated for several days without removing the
brushes, which is not recommended. If this occurs, reverse the brush so that the bent bristles are
automaticallystraightened.

This may wear out after years of use. If this occurs the water collection performance will decrease. It should
bereplaced by anauthorizedServiceAgent.

The filter prevents clogging of the spray nozzle and should be periodically cleaned. Use pressurized air/
waterfor cleaning.

Ifthe spray ofthe nozzle becomeblocked, slide thenozzle cover offandremove nozzle washin clean water
