The handle of your machine can be adjusted to any comfortable work position. Simply lift the handle-locking device located on the lower handle shaft to release the lock. Then adjust the handle to the desired position and push down firmly with hand or firmly with foot pressure to lock the handle in place.
Adjust the handle to a position where you can control the machine and where the disc surface balances flat and level on the floor. Typically, the upper handle cross
bar should be adjusted to a height 1” under the bottom of the back trouser pocket. Do not operate until Handle Quick Release is properly adjusted.

General Guidelines
Ca
ll 1
-8
88
Your roto is a very sensitive and powerful unit. When in operation, it should be guided gradually and smoothly without sudden or rough motions. Practice with the machine on a smooth surface, in a remote untravelled location, first until you have experience in operating the unit.
To move your machine to the right, slowly apply SLIGHT UPWARD pressure on the handle with both hands.
To move the machine to the left, slowly apply SLIGHT DOWNWARD pressure on the handle again with both hands.
To move the machine directly forward, torque the handle SLIGHTLY DOWNWARD on the LEFT side.
To move the machine to the rear, torque the handle SLIGHTLY DOWNWARD on the RIGHT side.
Your machine will operate differently on various surfaces. For example, there will be much more resistance when the machine is used with a shampoo disc on a carpeted
surface than with a polishing disc on a smooth surface.
If there is an incidence of fuse blowing, the roto should be used on a 20 amp circuit wherever possible.

A safety lock-out switch has been provided to prevent accidental start-up of your
machine. Press this lockout switch, (located on top of the switch box, between the handle grips) forward to release the operating lever. The lockout switch will spring back into the safety lock position when you release the switch lever.
With the safety switch in the forward position, pull up on either the right or left hand trigger switch located under the handle grips to operate the machine. To stop the
machine, simply release the trigger, allowing the safety switch to re-engage.

Remove the electrical plug from the wall outlet.
Put the handle into the upright position. Tilt the machine back so the handle is flat on the floor and driving assembly is perpendicular to the floor.
Hold the driving assembly in both hands and turn it clockwise in a jerking motion. (A screwdriver may be inserted between the drive lug and clutch plate to assist in the release of a jammed driving assembly.)
Always remove the driving assembly before standing the machine upright for storage. There is a vertical lug on the cord winder bracket for hanging the driving assembly.
Solution Tank (Gravity Feed)
To empty the tank, close the tank shutoff valve, remove the bottom end of the solution hose from the hose barb on the Electro Valve.
Hold the disconnected end of the solution hose in a bucket or other container. Open the shutoff valve and let the solution drain from the tank.
Check the filter in the tank to ensure it is not clogged.

OVERHEATING OF MOTOR
The Roto has been operated for long periods of time on low voltages, which causes excessively
high operation temperatures which, in turn, may result in damage to the insulation on the wind
ing. Low voltage may result from using an extension cord of lesser wire size than #12.
It is recommended to obtain a #12 three-wire extension cord if it is necessary to use more than
one 50 foot cord.
Note: The 17” and 20” machine (1-1/2 HP) motor plate states a 40 degree C (centigrade)
heat rise. This means a rise of 104 degrees F (Fahrenheit). Add to this 70 degrees F
for room temperature, and you will find that the motor will seem very hot (174 degrees F).
This is not cause for alarm.
NOTE:
Motors can normally run too hot to touch. An overheated motor may give off an oder, run slow, start slow, blow fuses, and get hot enough to boil water on its surface.

1.
Remove the switch cover by removing two screws and lifting cover straight up.
2.
The Roto main switch and Electro Valve switch are now exposed and can be replaced.
Note: To avoid incorrectly connecting the wires on the new switch, hold the old and new switch side by side before disconnecting any wires. Disconnect one wire from the old switch, move it to the same terminal on the new switch, and connect it securely. Move the second wire from the old switch to the new switch, and so on.
3.
Reverse the above procedure to re-assemble.
The tab extension on the front side of the cover fits inside the top of the handle tube. Take care not to damage the wire insulation when reassembling the cover.

Repairs of the motor gear unit itself are usually not recommended unless the mechanic has had experience with these motors and gear cases.
We recommend referring the repair to a local service center or contact your distributor for the
latest repair procedures. For those who wish to repair motor gear units themselves, the
illustrations in the Product Guide show the order of assembly quite clearly. On gearboxes, be certain to use the lubricants and sealers specified in the places spelled out in the parts list.
