NOTE: The reading and understanding of the Owner’s Manual is imperative prior to operating this machine. If you or your operator(s)
cannot read English, have this manual explained fully before attempting to operate this machine. Children should be supervised to
ensure that they do not play with the appliance. This machine is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge.
DANGER means: You or other staff can suffer a serious injury or death if the instructions marked
with DANGER on this machine or in these user instructions are ignored or not followed. Read the
entire user manual before you use the machine.
WARNING means: You or other staff can suffer an injury if the instructions marked with WARNING
on this machine or in this user manual are ignored or not followed. The machine or other property
may also be damaged if instructions marked with WARNING are ignored.
Under adverse conditions, a mixture of dust and air can be explosive. Sanding/polishing wooden
floors can create an environment that can be explosive. The safety routines below must be followed:
• Cigarette lighters, control lamps and all other sources of ignition can cause explosions if they
are active during sanding. All sources of ignition should be extinguished or, if possible, removed
completely from the work area.
• In work areas with poor ventilation, an explosive environment can occur if certain flammable
materials (solvents, thinners, alcohol, fuel, certain polishes, wood dust, etc) are in the
atmosphere. Floor grinders can cause slightly flammable materials and vapors to burn. Read the
manufacturer's label on all chemicals to be used so that you can determine the flammability.
Ensure that the work area always has good ventilation.
• Hitting a nail during sanding can produce sparks and cause an explosion or fire. Always use a
hammer to pound in any metal pieces before sanding the floor. Always keep a fire extinguisher
(ABC-class or water) available.
Use of a machine that is not complete or that is not fully mounted can result in personal injury
or damage to property. Never use these machines before they are fully mounted. Ensure that all
fastening devices are fixed. Make adjustments as defined in the machine specifications.
Read through the safety instructions carefully and inform your employees and users so no one comes to harm when using the machine.
Then, save the instructions. The manufacturer is not liable for personal injury or machine damage due to incorrect operation of the
machine. The machine may only be used by authorized persons that have been trained in its function.

Safety Instructions (Cont.)
Never remove or disable the ground in the electric cable.
Consult an electrician if the ground is missing or if you suspect that your circuit is not
properly grounded.
There is a risk of electric shock if the machine is used in a circuit that breaks repeatedly or is under-
sized. Allow an authorized electrician to control the fuse, breaker or power supply.
There is a risk of personal injury if the grinder runs over and damages the cord. Ensure that the cord
does not come into contact with the sanding disc. Always lift the cord over the machine and grind in
a direction away from the cord. Do not pull the machine by the cord.
Always use a ground that breaks the current immediately in the event of a fault in the electrical
system or in the extension cord.
In order to prevent unintentional start of the machine, the power cord must be
removed when the machine is not in use or during service.
Moving parts of the machine can cause serious personal injury and/or material damage. Keep hands,
feet and loosely fitting clothing away from all moving parts of the grinder.
Because dust from sanding (red lead, certain types of wood and metal) is hazardous to health, a face
mask of at least class P2 must be used.
There is a risk of damage to the eyes and/or body if protective clothing and/or protective
equipment is not used during sanding. Always use protective glasses, protective clothing, ear
protection and a face mask of at least class P2 during sanding.
Read the instructions
contained in this user
and maintenance
manual before using
the machine.

To minimize dust in the environment use a vacuum cleaner intended for wood dust. The air flow
on the vacuum cleaner should be at least 245m³/h. We strongly recommend the Bona®DCS™
for best results.
Store contained wood dust outdoors in a safe place due to the risk of fire. Never leave contained
wood dust unsupervised.
Always keep a fire extinguisher (ABC-class or water) available.
Take precautionary measures to ensure that the machine is not damaged during transport.
Be careful with cords. Use the correct power cord with the correct length (see accessories list).
Never carry the machine by the cord. Never pull power cords from the machine or wall socket
with strong movements. Protect the power cords against heat, oil and sharp edges. Power cords
longer than 50 ft (15.24m) should not be used.
Remove the power cord from the machine when it is not in use. Ensure that the machine does
not start unintentionally. Never carry a connected machine. Ensure that the breaker is not on once
the machine is connected to a power socket. Never use the machine if the start handle does not
function as it should.
Inspect the machine regularly. If you discover damaged parts, replace them at once. If necessary,
contact Bona or staff approved by Bona.
Because this construction is in many ways unique, use of other spare parts and accessories than
Bona®original spare parts can cause a risk of personal injury and/or damage to the machine.
Ensure that the machine is always in good condition. Keep the machine clean for better and safer
use. Follow the instructions concerning the replacement of accessories. Inspect the power cords
regularly. Repair or replace defective parts if they are damaged.
Store the machine in a dry and locked area when not in use.
Do not forget to put on the tool before you start the machine. Always check that the sanding
paper is correctly adjusted before you begin sanding.
Keep unauthorized persons away from the work site. Do not allow unauthorized persons to come
into contact with the machine or power cords.
Do not misuse the machine. The machine works better when it is used according to its capacity
and design. Allow the motor to "rest" during periods of heavier use. The motor will cool better,
thus increasing its lifespan.

Handling (Cont.)
It is important to make sure that the sanding is carried out in a methodical fashion to ensure that all areas
of the floor surface are sanded equally. Although the FlexiSand Power Drive™can be used in any direction
on the floor, making it ideal for patterned floor, for the best results on a strip or plank floor walk forwards and
backwards with the grain of the wood in a slow, steady manner.
Using the FlexiSand Power Drive™(cont.)
The sanding process
The FlexiSand Power Drive™system is not used like a 'normal' buffing machine with the handles held at the waist and the machine
moving from side to side when sanding.The counter-rotating cog construction of the Bona® FlexiSand Power Drive™equalizes the sanding
force so that the machine stands more or less still during operation and is controlled by simply walking backwards and forwards in the
same way as a belt sander is used.
The Bona®FlexiSand Power Drive™system is designed to be used in a variety of different sanding situations. However, it is not designed
to replace a traditional belt sanding machine and where a floor is uneven due to cupping or similar issues it is recommended that an
initial sanding using a belt sander with a 36/40 grit belt is made. For other sanding operations, the following methods are suggested:
To remove finish from a coated floor:
1) Start sanding with Bona GREEN Ceramic abrasives, grit
36 – 60 depending on how aggressive you need to be to
remove old finish and stain. Check the abrasives frequently
and replace as required to maintain a full, aggressive cut.
3) For final cut, use Bona BLUE abrasives in either grit 100
or 120 along with the ¼” Intermediate Pads to final prep
flooring surface for a sealer coat.
2) After using Bona GREEN Ceramic abrasives on the coarse –
medium cuts, switch to Bona BLUE abrasives for the medium
– fine cuts along with the ¼” Intermediate Pads: 60 – 120
grits.
4) For a final cut for a stained floor, Black 120 grit
with the ¼” Intermediate Pad is recommended.
Disclaimer: Depending on the specie or flooring type being sanded (strip vs. parquet or multi-specie), extra steps or variations of the steps listed
above may be required. You may also want to use the ¼” Intermediate Pads on all sanding steps to minimize scratch depth and bouncing or
hopping of the Bona® FlexiSand Power Drive™. Contact your local Bona Territory Manager or Technical Services with questions.

Handling (Cont.)
The sanding process (cont.)
Transport position
To sand after a belt sander has been used:
Follow the same process as noted on the previous page. If belt sanding has been carried to a higher grit, such as 80 grit, then simply
use the FlexiSand Power Drive™system for the final sanding.
When sanding prior to staining:
It is important that scratches are not left on the floor as the staining process will highlight any remaining scratches. The Bona®
FlexiSand Power Drive™is perfect for the final preparation before staining. The final sanding grit required for the Bona®stain systems
will be noted in the appropriate data sheet.
Bona®Interface Pads:
The Bona®FlexiSand Power Drive™as supplied has 4 x 150mm grinding pads that provide uniform sanding on a hardwood floor.
However, if the floor is uneven then the machine may 'jump' a little when sanding to bare wood. A 1/4" intermidiate pad may be used to
stabilize sanding. Some movement is normal during rough sanding and can indicate that more sanding is needed to get the surface flat.
Another issue that may be faced is that on soft wood species 'dish out' of the wood grain can sometimes happen.
To reduce the possibility of these issues, 4 x 6" (150mm), .25" (5mm) thick Interface Pads are supplied with the FlexiSand Power
Drive™. To fit them, first make sure that the grinding plate is clean. Place the Interface Pad onto it with the soft dark black side facing
towards the machine with the hook and loop side facing outwards. Then, apply the required Bona®abrasive disc.
Using the Interface Pads will allow the FlexiSand Power Drive™to follow the contours of the floor more efficiently, making the sanding
process easier and more comfortable.
Always remove the dust skirt and the drive plate or sanding disc before transportation. Always vacuum and
clean machine after use. When transporting the machine via vehicle, make sure that the machine is securely
fastened through the wheels to avoid movement.
1) Remove the drive plate. 2) Tip the machine backwards and remove the dust skirt.
