Silica Vacuum Warning
Grinding/sanding of masonry, concrete, metal and other materials with silica in
their composion may give o dust or mists containing crystalline silica.
Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks.
Repeated and/or substanal inhalaon of airborne crystalline silica can cause serious or fatal respiratory
diseases, including silicosis. In addion, California and some other authories have listed respirable
crystalline silica as a substance known to cause cancer. When grinding such materials, always follow
respiratory precauons. Use appropriate NIOSH-approved respiratory protecon and OSHA approved
vacuum where dust hazard may occur.
CALIFORNIA PROPOSITION 65 MESSAGE Some dust created by power sanding, sawing, grinding, drilling,
and other construcon acvies contain chemicals known (to the State of California) to cause cancer,
birth defects or other reproducve harm. Some examples of these chemicals are: • Lead, from lead-
based paints • Crystalline silica from bricks, cement and other masonry products • Arsenic and
chromium, from chemically treated lumber. For further informaon, consult the following sources:
hp://www.osha.gov/dsg/topics/silicacrystalline/index.html
hp://www.cdc.gov/niosh/docs/96-112/
hp://oehha.ca.gov/prop65/law/P65law72003.html
hp://www.dir.ca.gov/Title8/sub4.html
Your risk from these exposures varies depending on how oen you do this type of work. To reduce your
exposure to these chemicals, work in a well-venlated area, and work with approved safety equipment,
such as dust masks that are specially designed to lter out microscopic parcles. The use of a dust
extracon device should always be used when grinding/sanding dry with Onoor equipment. To achieve
a high level of dust collecon, use an industrial HEPA vacuum cleaner.

Important Safety Instructions
To reduce the risk of re, electric shock or injury:
Read all instrucons before using this oor machine.
1) DO NOT leave the oor machine plugged in when not in use. Unplug from the outlet when not
in use and/or before servicing.
2) Electric shock could occur if exposed to rain. Store indoors.
3) This is NOT a toy. Close aenon is necessary when used around or near children.
4) Use only as described in this manual. Use only manufacturer's recommended attachments.
5) DO NOT use with damaged cord plug. If the oor machine is not working as it should because it
has been dropped, damaged, le outdoors, or dropped into water, contact the manufacturer or
authorized service center.
6) DO NOT handle the plug or operate with wet hands.
7) DO NOT pull or carry by cord, use power cord as a handle, close a door on cord, or pull cord
around sharp edges or corners. DO NOT run floor machine over the cord. Keep cord away from
heated surfaces.
8) DO NOT unplug by pulling on cord. To un- plug, grasp plug, not the power cord.
9) DO NOT put any object into motor openings.
10) Keep hair, loose clothing, ngers and all parts of body away from moving parts.
11) DO NOT use a vacuum without the proper manufacturer’s filters in place.
12) DO NOT operate where anesthecs and oxygen are used.
13) DO NOT use around ammable or combustible liquids such as gasoline or use in areas
where they may be present.
14) Replace damaged or worn parts immediately with genuine Onfloor equipment parts to maintain
safety and protect your limited warranty.
15) Floor sanding can result in an explosive mixture of fine dust and air. Use a oor sanding
machine only in a well-ventilated area.
16) This oor machine must be connected to a properly grounded outlet only. (See grounding
method on page 6)

Grounding Instructions & Methods
Improper use of the grounding plug can result in a risk of electric shock!
This floor machine must be grounded. Grounding provides a path of least resistance for electrical current
to reduce the risk of electric shock.
This machine is equipped with an equipment-grounded plug. The plug must be inserted into an
appropriate outlet that is properly installed and grounded in accordance with all local codes and
ordinances.
If repair or replacement of the cord or plug is necessary, DO NOT connect the grounding wire to either flat
blade terminal. The insulated wire with an outer surface that is green with or with- out yellow stripes is the
grounding wire.
The oor machine is for use on a nominal 120 volt circuit and has a grounding plug that
looks like the plug illustrated in (Fig A). A temporary adaptor that looks like the adaptor
illustrated in (Fig B & C) may be used to connect the plug to a 2-pole receptacle as shown
in (Fig A) if a properly grounded outlet is not available.
The temporary adaptor should be used only unl a properly grounded outlet (Fig A) can
be installed by a qualified electrician. The green color rigid ear, lug, or like extending from
the adaptor must be connected to a permanent ground such as a properly grounded
outlet box cover. Whenever the adaptor is used, it must be held in place by the metal
screw (Fig C).
WARNING: Improper connecon of the equipment-grounding conductor
can result in a risk of electrical shock. Check with a qualied electrician or
service person if you are in doubt as to whether the outlet is properly
grounded. DO NOT modify the plug provided with the machine. If it will not
t the outlet, have a proper outlet installed by a qualied electrician.
NOTE: In Canada, use of a temporary adaptor is not permied by the
Canadian Electrical Code.

Operating Instructions
1) Clear the oor of any materials or objects.
2) Select and install the accessory tools required for the job. (See p 8 for installaon instrucons.)
3) Move the handle from the upright “storage” posion to the angled “operang” posion and lock in
place with the quick release pin.
4) Place your hands on the handle grips and apply slight pressure to lighten the load on the tools. DO
NOT li the tools o of the ground!
5) Push the start switch toggle forward to “ON” posion. Motor will start.
6) When the machine is running, remove handle pressure and lower completely onto the working
surface.
7) To stop the machine push, start switch toggle backward to “OFF” posion.
Note: If machine unexpectedly shuts down due to a circuit overload, check to see if the on-board circuit
breaker has opened. This is located on the handle beneath the handle grips. If the buon is extended
out, wait 1 minute before pushing in to reset. If the breaker will not reset, wait several minutes before
aempng to reset again. If on-board breaker has not opened, check breaker box feeding the outlet
that the machine is plugged into. TURN MACHINE TOGGLE TO “OFF” POSITION BEFORE RESETTING
CIRCUIT BREAKER.
DO NOT aempt to operate this unit if the machine is not fully assembled. When
servicing or replacing accessories turn OFF the machine and disconnect from the
power source.

When installing or changing tools, turn OFF the
Machine and disconnect the power cord from the electrical outlet
Before Installaon or Changing Aachments:
1. Unplug the machine from the wall outlet.
2. Ensure handle is in the storage posion (straight up) and locked in place with the quick release pin.
3. Tilt machine back by bracing it with your foot unl the handle is lying on the oor and the three
heads are fully exposed. Note: It is recommended that a towel or pad is placed under the machine to
protect the oor.
Changing and Installaon of Aachments
Always wear protecve gloves when installing or removing aachments,
1. Posion the rst aachment head at 12 o’clock.
2. Using one hand as leverage and the other to reach beneath the boom side of the aachment and
pull up towards yourself to free it from the mounng pins. Turn the aachment 180 degrees and pull up
again and the aachment will be freed.
3. Select the aachment required for the job, line up the holes on the aachment with the four metal
pins protruding from each of the three heads.
4. Push aachments on by hand and if necessary, carefully tap it into place with a rubber mallet.
5. Repeat steps 1 thru 4 with the remaining 2 aachments.
6. Carefully raise the handle, supporng the axle with your foot to control the head of the machine as it
is placed on the oor.
7. Since the aachments are dierent heights, you may need to adjust the dust skirt to make sure it is
level with the aachments. This will ensure clean and virtually dust-free operaon.
8. To adjust skirt, align the skirt with the center of the machine and wrap it around allowing boom
edge of skirt to contact oor.
9. Move the handle back to the operang posion and lock in place with the quick release pin.

Belt Changing Instructions
1) Unplug the machine from power source.
2) Place handle in the straight up posion and lock in place using the quick release
pin.
3) Using handle, lt the machine back unl handle is resng on the oor.
4) Remove tools from machine.
5) Remove (9) 1/4 -20 hex bolts and lock washers from the perimeter of cover plate. Remove plate from
machine.
6) Vacuum dust and debris from inner bowl.
7) If only the lower belt needs replacing, follow steps below. However, if center or top belt needs
replacing, it will be necessary to remove any belts beneath it in order to remove the failed belt.
8) On some older machines, retaining plates were not used on the face of driven pulleys. If your machine
is congured this way go to step 11.
9) On machines with old style retaining plates, each driven pulley has (3) Allen socket screws holding the
retainer plates in place. Remove these (9) screws and (3) retaining plates then go to step 11.
10) On machines with newer retaining plate design, only remove the single 1/4-20 hex bolt from each of
the driven pulleys. Then rotate the retaining plate slightly unl keyhole openings in plate allow removal.
If plate will not rotate, loosen buon head screws slightly and rotate plate. There is no need to remove
the buon head screws.
11) With the retaining plates removed, and using gloves, pull the belt away from large pulley using a at
screwdriver while slowly rotang pulley. Be careful not to pinch ngers between belt and pulley. Repeat
unl belt is o driven pulley.
12) To install new belt(s) start with the belt closest to the motor. Wrap belt around center driving pulley
rst. Then start the belt around the large driven pulley as far as possible. Then using gloves and grabbing
the center of the pulley hub, force the pulley to rotate. Belt should seat itself onto teeth of pulley.
Repeat steps on other pulleys as required.
13) Reinstall retainer plates if equipped.
14) Replace cover plate and hardware.
15) Replace tools and using handle lt machine back to upright posion.

Inner Bowl Removal Instructions
This procedure requires a set of retaining ring plyers and safety glasses to complete. If you do not have
retaining ring plyers they can be purchased at Lowes, Home Depot, Harbor Freight and other tool stores
for about $20.
1) Unplug machine from power source.
2) Place handle in straight up position and lock in place using the quick release pin.
3) Using the handle, tilt machine sideways until handle is resting on the floor to one side.
4) Remove tools from machine.
5) Remove the (9) ¼-20 hex bolts and lock washers from the perimeter of the cover plate. Remove plate
from machine.
6) Vacuum dust and debris from inner bowl.
7) Locate bolt in center of center driving pulley. While holding one of the large driven pulleys to prevent
rotation, remove this center bolt and its flat washer. On some machines this removal requires a hex
(Allen) wrench while later machines require a 7/16 wrench or socket.
8) On some older machines, retaining plates were not used on the face of the driven pulleys. If your
machine is configured this way go to step 11.
9) On machines with old style plates, each driven pulley has (3) Allen socket screws holding the retainer
plates in place. Remove these (9) screws and (3) retaining plates then go to step 11.
10) On machines with newer retaining plate design, only remove the single ¼-20 hex bolt from each of
the driven pulleys. Then rotate the retaining plate slightly until keyhole openings in plate allow removal.
If plate will not rotate, loosen button head screws slightly and rotate plate. There is no need to remove
button head screws.
11) With retaining plates removed and using gloves, pull the belt away from large pulley using a flat
screwdriver while slowly rotating the pulley. Be careful not to pinch fingers between belt and pulley.
Repeat until belt is off pulley. Repeat this process until all three belts have been removed.
12) Remove center driving pulley from motor shaft. This may require prying behind pulley(s) with a large
flat screwdriver or a small pry bar. In some extreme cases it may even require the use of a pulley puller
tool. Also remove square key.
13) With center pulley removed, locate retaining ring at center of bowl (just behind where center pulley
was before removal). Wear safety glasses. Using a pair of retaining ring plyers, remove this retaining
ring.
14) Using a clean cloth, wipe away any dust or dirt from the groove where retaining ring was located.
15) Using two of the large pulleys as handles, pull away from machine. This should allow entire inner
bowl with large pulleys intact to slide out of machine. If bowl will not slide out try lifting up on pulleys at
the same time while pulling away from machine. In rare instances it may require renting a Harmonic
Balancer Removal tool from an auto parts store to extract the bowl. If this type of difficulty is
experienced contact factory for further guidance.

11
Inner Bowl Bearing Replacement
With the bowl removed, upper bowl bearings can be serviced.
This job requires a set of retaining ring plyers, safety glasses and the proper replacement bearings. The
bearings used here are 6009 bearings with double seals. These are available from Onfloor, part number
245666. It is very important to wear the safety glasses especially when removing and installing the
retaining rings. If you do not have retaining ring plyers they can be purchased at Lowes, Home Depot,
Harbor Freight, and other tool stores for about $20.
The steps to remove the inner bowl are covered on page 10 so we will address what to do after removal
is accomplished.
When replacing the bearings in the top of the Inner Bowl there are some things that should be pointed
out to insure longer life and better performance. The first has to do with the method used to remove
and install the new bearing. Remove the retaining ring and proceed to the steps below.
Installation Using a Press
The best method to remove and install new bearings is to take the inner bowl assembly to a hydraulic
press and press the bearings in and out. When using this method, it is important to properly support the
cast aluminum bowl so as to prevent cracking the casting. This is accomplished by supporting the casting
as close as possible to the center while allowing room for the bearings to exit. See illustration A. When
pressing the old bearings out it is acceptable to use almost any device as a pushing tool as long as it will
fit through the center opening without touching the casting. This means a piece of metal tubing or rod
or even a piece of wood that will fit through a 2-11/16” diameter hole. We do not need to be cautious
about damaging the old bearings to remove.
When installing the new bearings, first clean the surface of the opening where the bearings are to enter.
Support the casting properly (See illustration A on page 12). Use a pusher device that will contact the
OUTER RACE. It is important that you do NOT press on the inner race to install the bearings. This will
damage the bearings and shorten their life. The best choice for a pushing tool is a round rod/pipe or
piece of wood that is just under 3” diameter that will pass through the 2.95” opening in the casting.
Many people find a large socket that makes contact with the outer race but fits through the opening.
The first bearing must be pressed all the way down to the bottom of the cavity, followed by the spacer
ring (you don’t want to forget this) then, finally the last bearing. When properly installed the last bearing
will be below the retaining ring groove and the retaining ring should go in easily.
Installation without a Press
When using this method, use a short piece of wood and a mallet/hammer to drive the old bearings from
the cast inner bowl. I suggest wood to prevent causing damage to the casting during this step. Support
the casting on 2 blocks of 2 x 4 or 4 x 4 lumber (see illustration on page 12). We don’t have to be
cautious about damaging the old bearings. When installing the new bearings, first clean the surface of
the opening where the bearings are to enter. Turn the bowl over and rest its center on a short block of 4
x 4 lumber. (See illustration A on page 12). Place the first bearing in the center opening and place a flat
piece of wood or steel across the top of the bearing. It is important that you drive the bearing in straight
AND that you do this by applying force to the outer race. It is OK that the flat steel or wood is contacting
the inner race as long as the outer race is also in contact. Tap the wood/steel plate with the hammer
and slowly drive the bearing until it is flush with the top of the casting. Now there are 2 ways to

12
proceed. One is to find a round object (large socket, steel tube, steel rod, etc.) that will contact the outer
race and also fit through the opening in the casting and use this object to further tap the bearing to the
bottom of the cavity. The other way is to use a short wooden dowel ½ or ¾” in diameter and to tap the
outer race with small taps as you work the dowel around the perimeter of the outer race as you
gradually drive the bearing down to the bottom. When the first bearing is installed, follow with the
spacer ring (you don’t want to forget this) then; repeat the same process with the top bearing. Then
install the retaining ring.
An Important Detail
After the bearings and retaining ring has been installed but before the bowl is installed, it is very
important that you cover the top of the upper bearing with grease. It makes no difference what the
quality of the grease is because it is not being used for lubrication it is serving as a barrier to prevent air
born concrete dust from reaching the top bearing. We suggest using grade 3 wheel bearing grease with
a putty knife and fill the entire cavity (about 3/16” deep) that exists above the top bearing. This will
prevent dust infiltration which is the main cause of this bearing’s failure. The attached Photo shows the
top bearing before and after grease has been applied.

Pulley Bearing Replacement
This job requires a set of retaining ring plyers, safety glasses and the proper replacement bearings as
well as some general hand tools. The bearings used here are 6203 bearings with double seals. These are
available from Onfloor, part number 245321. It is very important to wear the safety glasses especially
when removing and installing the retaining rings. If you do not have retaining ring plyers they can be
purchased at Lowes, Home Depot, Harbor Freight, and other tool stores for about $20.
Once the bearings are determined to be in need of replacement, follow the steps below to remove the
pulley(s) that need replacement bearings:
1. With the handle in the straight up position, tilt the machine to its side so the machine is resting
on the side of the outer bowl and one of the handle grips. This makes the machine stable and
less likely to tip over.
2. Remove the tools.
3. Remove the 9 fasteners around the perimeter of the dust cover. On some machines these were
Philips head screws. On later machines these are ¼-20 hex head bolts requiring a 7/16 socket
and rachet or a 7/16 wrench. Remove dust cover.
4. Remove belt keeper plates on the face of each pulley. To do this you will need to remove the 3
small screws on older machines. On later model machines it is only necessary to remove the
single hex head bolt on each pulley. Then rotate the keeper plate a few degrees until the
keyhole openings in the plate align with the remaining screw heads and lift the plate off. An
upgrade kit is available to change to this new keeper plate system. For all 16” machines built
since 2007 and for 20” machines built prior to the heavy-duty belt system the part number for
the upgrade kit is 603775. For 20” machines with heavy duty belt systems the kit number is
603783. There are some much older machines built before 2007 that have pulleys without
holes that the kits will not work on.
5. Wear gloves to work the belt off the pulley teeth while slowly rotating pulley. Belt will come off
the large pulley. Be careful not to pinch your fingers.
6. To remove pulley, use a deep well 15/16 socket wrench to remove the locking hex nut located
down inside the pulley center opening. The flat washer located behind the nut is a 16mm flat
washer and not a standard SAE type so be careful not to lose them as they may be challenging
to purchase locally. Pull the pulley straight out and away from the machine. There is also a small
spacer located behind the pulley. Be careful not to lose this as well.
With the pulley removed we can proceed with bearing replacement. Look at the pulley from the back
and you will see the retaining ring that secures the bearings in place. Wearing your safety glasses and
using the retaining ring plyers remove the retaining ring.
Installation Using a Press
The best method to remove and install new bearings is to take the pulley to a hydraulic press and press
the bearings in and out. When using this method, it is important to properly support the pulley to allow
space for the old bearings to exit. This is accomplished by supporting the pulley as close to the center as
practical using 2 pieces of 2 x 4 lumber or 2 pieces of equal thickness steel. When pressing the old
bearings out it is acceptable to use almost any device as a pushing tool as long as it will fit through the
center opening without touching the pulley. This means a piece of metal tubing or rod or even a piece of

15
wood that will fit through a 1.29” diameter hole. The same 15/16 socket used to remove the nuts works
well for this. We do not need to be cautious about damaging the old bearings to remove. (see
illustration page 16)
When installing the new bearings, first clean the surface of the opening where the bearings are to enter.
If your pulley has the 4 drive pins installed, I suggest removing them for this process. You will need a
7/16 deep well socket for this. Stand the pulley in the press resting on its front face. Use a pusher device
that will contact the OUTER RACE. It is important that you do NOT press on the inner race to install the
bearings. This will damage the bearings and shorten their life. The best choice for a pushing tool is a
round rod/pipe or piece of wood that is 1-1/2” diameter that will pass through the 1.57” opening in the
pulley. (see illustration on page 16) Many people use a large socket that makes contact with the outer
race but fits through the opening. The first bearing must be pressed all the way down to the bottom of
the cavity, followed by the spacer ring (you don’t want to forget this) then, finally the last bearing. Be
careful not to over press especially if you left the drive pins in the pulley. When properly installed the
last bearing will be below the retaining ring groove and the retaining ring should go in easily.
Installation without a Press
When using this method, use a short piece of wood (or 15/16 socket) and a mallet/hammer to drive the
old bearings from the cast inner bowl. Support the pulley on a piece of wood to prevent damaging it.
We don’t have to be cautious about damaging the old bearings. When installing the new bearings, first
clean the surface of the opening where the bearings are to enter. Turn the pulley over and rest its front
face (or drive pins if present) on the piece of wood. Place the first bearing in the center opening and
place a flat piece of wood or steel across the top of the bearing. It is important that you drive the
bearing in straight AND that you do this by applying force to the outer race. It is OK that the flat steel or
wood is contacting the inner race as long as the outer race is also in contact. Tap the wood/steel plate
with the hammer and slowly drive the bearing until it is flush with the top of the pulley. Now there are 2
ways to proceed. One is to find a round object (large socket, steel tube, steel rod, etc.) that will contact
the outer race and also fit through the opening in the pulley and use this object to further tap the
bearing to the bottom of the cavity. The other way is to use a short wooden dowel ½ or ¾” in diameter
and to tap the outer race with small taps as you work the dowel around the perimeter of the outer race
as you gradually drive the bearing down to the bottom. When the first bearing is installed, follow with
the spacer ring (you don’t want to forget this) then; repeat the same process with the top bearing. Then
install the retaining ring.
Reinstall drive pins, pulley, belts, keeper plates, dust cover in reverse order of removal.
