Bypressing the pedal lightly with your foot, pull back the handle a littleto start the motor.The
brushes and the drum starts rotating. Pulling the handle further without pressing the pedal,
lowersthemachineandengages therotatingbrushesontothefloor.Tostopworking,takethe
handletotheverticalposition.
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
fullydownandMAXIMUMwhenitisfullyraised. Thishelpsyoutocompensateforthewear
ofbrushes and also tocontrolthe scrubbing effect.If there isno 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

Care of the machine
3.Stoptheliquiddischargeapproximatelyonefoot beforetheend
offorwardmotion.continue to move forward up to the wall without
pullingthepullhandle.
Sprayangle/areacan be 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@theincrement 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 take a U-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

For maximum life wash the brushes regularly. Ensure machine is in Transport mode when not in use. Store
additionalbrushes ina verticalposition toavoid bendingof bristles.Check forpermanent bendingof bristles
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
