DANGER: Failure to read the Operator's Manual before operating or servicing this sanding equipment

could result in injury to the operator or to bystanders and could cause damage to the

equipment. Read and observe all safety statements found in this manual and on the

sanding equipment. Make sure all labels, decals, warnings, cautions and instructions are

fastened to the equipment. Replace any that are damaged or missing. You must have

training in the operation of this equipment before using it. If the operator is unable to

read this manual, have it explained fully before they attempt to use this equip-

ment.

DANGER: Finishing wood floors can create an environment that can be explosive. The following safety

procedures must be adhered to:

• Cigarette lighters, pilot lights and any other source of ignition can create an explosion

when active during a sanding session. All sources of ignition should be extinguished or

removed entirely if possible from the work area.

• Work areas that are poorly ventilated can create an explosive environment when certain

combustible materials are in the atmosphere, i.e., solvents, thinners, alcohol, fuels,

certain finishes, wood dust and other combustible materials. The machinery can cause

flammable material and vapors to burn. Read the manufacturer's label on all chemicals

used to determine combustibility. Keep the work area well ventilated.

• An accumulation of dust can self-ignite and cause injury or damage and should be

disposed of properly. Always empty the dust into a metal container that is located

outside of any building(s).

• Do not empty the contents of the dust bag into a fire.

•In the event of a bag fire, injury can occur to the operator if the operator is tied or strapped

to equipment.

This machine was designed to supply abrasion to coated surfaces before recoating. Abrasion provides anchor sites

that promote adhesion of the new coating to the existing coating. This machine is suitable for use on factory finished

or site finished wood floors. This machine is recommended for beveled, micro beveled, and sculptured factory or

site finished wood floors. It is especially suited for use on uneven or sculpted floors where traditional methods

would otherwise damage the finish or alter the sculpting.

How to Operate the Machine

For a successful re-coat of an existing floor, first clean

thefloor toremove waxesand contaminants. Abradethe

wall line or any areas unreachable by the machine.

1. Connect the power supply cable to an

appropriatelygroundedandfusedoutlet. Connect

the power supply cable to the cord adaptor

attached to the control housing (see item 7 page

6). Press the selector switch to the start (S)

position. Once started allow the switch to return

to the run (R) position.

2. The recommended approach is to use the "pass"

method with this machine. A single pass consists

ofaforwardadvancementonthemachineanda

reversereturntothestartingpointwhileretracing

theforwardadvancement. Overlaptheprevious

pass and repeat. You may index in this way to

the right or left of the machine across the area to

bedone.

3. Usethe control levertolower the abrasivetothe

floor. Keep the machine in motion while the

abrasive is in contact with the floor. Adjust pace

for adequate abrasion. For best results index the

machine in 3" increments with a pace of 12-15

inches per second. See figure 5.

NOTE: For optimum abrasive life and uniform

results, rotate abrasive every 250 square feet.

NOTE: You may add up to 10 lbs. to the machine

which will enhance abrasion in some instances.

Tokeepyourabrasivesharp,reverseitevery200

squarefeet.

CAUTION: To prevent damage to the surface,

make sure the machine is always

moving when the abrasive is

contacting the floor.
