The SL-1218R
Orbital Polisher/Refinisher
Built by Essex Silver-Line Corporation
The SL-1218R will add a different dimension to your fleet of floor care machines.
The design allows the user to do the work of a polisher without knowing how to run a rotary polisher.
Applications Include:
ØScreening Floors after sanding with the SL-8 & SL-7
ØScreen and recoating polyurethane floors
ØWaxed floor Scrubbing & Polishing
ØWood Deck Refinishing
ØMaintaining Tile
The advantages of the SL-1218R over other orbital polishers include:
Ø1 HP sealed Baldor motor, protected from dust, fan cooled
ØThe weight of the machine is located in the base, giving it a low center of gravity.
ØLow center of gravity makes the machine very stable & easy to control
ØThe plate is the rental standard 12” x 18” size
ØThe plate is mounted in rubber in lieu of springs
ØLarger orbital action Movement (5/8”)
ØThe Plate is supported on all four corners by the rubber mounts, protecting the motor shaft!
Refinements you will find only on the SL-1218R:
ØWe use a rugged toggle switch (not a rocker switch)
ØOur switch terminates both wires
ØHeavy duty upgraded wheels
ØAll Fasteners are American standard (no metric)
ØOur Thermal Overload is accessible on the front of the machine
ØOur plate is enhanced at the Bearing for ease of service
ØHigher grade rubber components
ØTwist lock connections at the motor
ØHandle at the front of the machine for easy transport
ØOur motor Armature has a 50lb pre-load to absorb shock and start easier
ØWe have a Puller system available for repairs, to make plate removal easier

Silver-Line SL-1218R
Orbital Floor Refinisher
Owners Manual
Thank you for purchasing a SL-1218R floor refinisher. When used properly this unit will perform well as a
rental machine. Please review and follow the suggested procedures for operation of this machine.
A) Use the proper pad! Use a thick (1”) polishing pad (white) under the carpet to hold the abrasives (sandpaper/sandscreens) under
the machine and on the floor.
B) Between the carpet and the abrasive you should use a thick nylon pad. If a thin pad is used your customer will not achieve the
desired results. If no pad is used, the sandpaper may fly out from under the machine and injure the operator, other objects and
you may damage the machine. Note: Rule of thumb is one pad per room, the more pads used the better the results.
C) Use minimal chemicals on the surface being prepared (when needed). The machine can hydroplane if there is too much liquid and
lose its effectiveness.
D) Do Not Store the SL-1218R on the white pad.
Procedure for setting up your SL-1218R
Remove your machine form the box. Check the wiring connections and test the machine electrically.
Maintenance
Keep your machine electrically safe!
üReplace any broken or frayed electrical wires immediately!
üNever defeat the grounding system by eliminating the third prong on the machine plug or using an ungrounded receptacle.
üNever overload circuits or use fuses rated too high for the circuits.
üAlways remove the plug from the power supply when servicing any part of the machine.
Be sure to caution the customers:
üThat the thick polishing pad (white) is required at all times during operation of the machine.
üNot to use extension cords with this machine. The original 25 foot cord should be sufficient.
Control of the SL-1218R
A) Once the machine is started, it should glide smoothly, without excessive pull or vibration, across the floor. If the unit pulls to
either side or vibrates, making control difficult, check the current pad to see if it is properly seated on the carpet. Flip the pad
and rotate it 180 degrees and try the machine. If the machine still pulls, change the white pad and center it properly below the
SL-1218R.
B) The machine should be guided straight ahead to cover the floor at the rate required for thorough cleaning. Side to side movement
can be used to bring the unit to a new area. Excessive side to side movement will simply make the job tiresome and will not improve
cleaning, since the SL-121R8 is already oscillating in all directions in its normal action.

Trouble-Shooting
Silver-Line SL-1218R
A) The unit will not start:
üIs the unit well connected into the outlet?
üIs the Reset button (Thermo-contact switch) on the front of the machine set?
üAre the plugs between the handle and the base unit well connected?
üAre the male and female plugs in good condition?
üAre the wires well connected to the switch on the handle?
üAre the wires well connected into the motor?
üIs the wire cord in good condition?
B) The unit stops suddenly:
üCheck all points in section 1
üIs the thermo-contact switch operating properly?
üIs the switch on the handle in good and functional conditional?
üIs the capacitor of the motor in good and functional condition?
C) The plate of the unit is not oriented correctly with the casing:
üAre the rubber towers of the unit in good condition or broken off?
üAre the bolts in the towers broken?
D) The unit makes a humming sound without moving:
üCheck all points in section 1.
üIs there an object caught between the internal plate and the casing?
üIs the motor capacitor in good and functional condition?
üIs the shaft of the motor in good condition?
E) The unit starts slowly before picking up it regular speed:
üIs the starting switch of the motor in good condition?
üIs the switch in good condition?
üIs the wire cord in good condition?
F) The machine pulls to one side too much:
üCheck the Thick (1”) White Nylon pad for wear, flip the pad over and rotate it 180 degrees. Try the
machine to see if it will run properly.
üChange the Thick (1”) White Nylon Pad

Proper Application & Use of Nylon Pads
(For either Rotary or Orbital Polishers)
Color Use Application
White* Buffing For polishing floors where highest luster is desired
Green Scrubbing For general duty scrubbing and spot removal on floors
Black Stripping For heavy duty wet stripping of floors
*White pads should be used to drive sand screens and sandpaper on Orbital polishers
White nylon pads are the best pad for holding mesh screens for screen & recoats, light sanding or polishing a
resilient floor. They are also best for holding sandpaper when using the SL-1218R.
Green nylon pads are most useful in scrubbing a resilient floor and in applications that need a stiffer pad.
Black nylon pads are most useful in stripping a resilient floor, and are the coarsest pad available.
There are other colors of pad available for polishers. The white, green and black pads are the standard for
the rental industry and will fill all of your needs.
Applications for the SL-1218R:
With the use of sandpaper, sanding screens or nylon pads, the SL-1218R can be used on a
variety of surfaces. It is ideal for wood flooring, wood decks, and other hard flooring
surfaces.
ØHardwood Floor Screening & Refinishing
ØFinish Sanding for Hardwood Floors
ØScreening hardwood floors after sanding with the SL-8 & SL-7
ØDeck Refinishing
ØCleaning & Polishing Linoleum Floors
ØCleaning & Waxing Hardwood Floors
Use your SL-1218R Orbital Polisher for any application your standard rotary
polishers are used for at this time!
