Operator’s Manual are ignored or are not adhered to. Read and observe all DANGER statements found in this Operator’s Manual

and on your machine.

WARNING!

Injury can occur to you or to other personnel if the WARNING statements found on your machine or in this Operator’s Manual are

ignored or are not adhered to. Read and observe all WARNING statements found in this Operator’s Manual and on your machine.

CAUTION!

Damage can occur to the machine or to other property if the CAUTION statements found on your machine or in this Operator’s

Manual are ignored or are not adhered to. Read and observe all CAUTION statements found in this Operator’s Manual and on your

machine.

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 equipment.

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.

Introduction & Machine Speciﬁcations

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.

6. This sanding machine is designed to be operated with a remote

vacuum dust collection system or with the included dust bag. Follow the

procedures below:

Preparing Remote Vacuum Dust Collection Systems

To prepare the machine for remote vacuum dust collection systems that

have a 2” hose end, follow this procedure:

1. Install 2” hose end (ﬁgure 2, A) directly over the exhaust tube (ﬁgure

2, B).

2. The exhaust tube can be rotated for optimum convenience.

To prepare the machine for remote vacuum dust collection systems that

have a 1 ½” hose end, follow this procedure:

1. Install the 2” x 1½” hose end adaptor (Part No. 30563A) (ﬁgure 2, C)

over the exhaust tube (ﬁgure 2, B).

2. Insert 1 ½” hose end (ﬁgure 2, D) into the adaptor (ﬁgure 2, C).

NOTE: Start the remote vacuum collection system before operation.

Preparing to use the included dust bag

To prepare the machine for use with the included dust bag, follow this

procedure:

1. Install the dust bag by pressing the end onto the exhaust tube until the

ring locks into the groove (ﬁgure 3). This is best done by pressing on the

back of the bag opening with the palm of your hand.

2. The exhaust tube can be rotated for optimum convenience.

3. To remove the dust bag from the exhaust tube, pry up the end of the

bag opening to partially release the internal rib from the groove, then pull.

4. To empty the dust bag, unzip the disposal ﬂap and force contents out

by inverting the bag.

NOTE: For best results, empty frequently. Follow all warnings posted in

this manual and on the dust bag.

How to Operate the Machine

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

to remove waxes and contaminants. Abrade the wall line or

any areas unreachable by the machine.

1. Connect the power supply cable to an appropriately

grounded and fused outlet. 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 of a forward

advancement on the machine and a reverse return to the

starting point while retracing the forward advancement.

Overlap the previous pass and repeat. You may index in this

way to the right or left of the machine across the area to be

done.

3. Use the control lever to lower the abrasive to the 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 ft2.

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

enhance abrasion in some instances. To keep your abrasive

sharp, reverse it every 200 square feet.

CAUTION!

To prevent damage to the surface, make sure the machine is

always moving when the abrasive is contacting the ﬂoor.

4. Use the control lever to raise the abrasive when reversing or

overlapping.

5. You may advance the machine against (ﬁg. 5A) or with

the direction of the ﬂooring (ﬁg. 5B) to reduce the amount of

unreachable area and best coverage on the ﬂoor.

6. Press the selector switch to the off position whenever

emptying the dust bag or when the job is completed.

Disconnect the supply cable.

7. Empty the dust bag frequently.

Sander Adjustment Procedures

DANGER!

Electrocution could occur if maintenance and repairs are

performed on a unit that is not properly disconnected from the

power source. Disconnect the power supply before attempting

any maintenance or service.

DANGER!

Moving parts of this machine can cause serious injury and/

or damage. Keep hands, feet and loose clothing away from all

moving parts of the sander.

The following information provides details on how to adjust

different features/controls of the sander.

Dust Shoe

To adjust the dust shoe follow this procedure:

1. Disconnect machine from power supply.

2. Loosen the four screws fastening the dust shoe to the

chassis.

3. Adjust the dust shoe towards the drum to improve recovery of

ﬁne particles.

4. Adjust the dust shoe away from the drum to improve recovery

of coarse particles.

5. Align the dust shoe with the drum and tighten screws.

Leveling

To adjust the machine leveling follow this procedure:

1. Locate the leveling screw. See ﬁgure # 6.

2. Tighten the screw (compress the leveling spring) to sand

heavier on drive belt side of sanding drum.

3. Loosen the leveling screw (relax the leveling spring) to sand

heavier on the side opposite the drive belts as shown in ﬁgure 6.

ROUTINE MAINTENANCE

The following items need to be periodically inspected and

maintained to keep your sander in good working condition.

Wheels

Periodically remove the debris from the truck and caster wheels.

Debris can cause waves on a sanded surface.

Dust Bag

Remove the dust bag from the machine and shake it thoroughly

to remove the sanding dust from the dust bag. Turn the dust

bag inside out and machine wash in cold water to prevent pore

blockage and loss of dust recovery.

Drive Belt

Periodically check the drive belts for cracks or frayed edges.

Frayed edges may indicate poor tracking. Realign effected belt.

Bearings

Periodically check the bearings for wear or damage according to

the following schedule.

Arbor shaft

Relubricate every 150 hrs. w/.10 oz. of a NLGI grade 2, -300F to

2500F, 58-75 SUS at 2100 F, grease lubricant.

Motor shaft

after 1st 5000 hrs.

Fan shaft

After ﬁrst 1500 hrs.
