OPERATION AND MAINTENANCE MANUAL FOR
ROTOSTRIP –SURFACE PREPARATION TOOL
FOR PROFESSIONAL USE ONLY
IMPORTANT SAFETY INFORMATION ENCLOSED.
READ AND UNDERSTAND THIS MANUAL BEFORE OPERATING THIS PRODUCT.
IT IS YOUR RESPONSIBILITY TO MAKE THIS SAFETY INFORMATION
AVAILABLE TO OTHERS THAT WILL OPERATE THIS PRODUCT.
FAILURE TO OBSERVE THE FOLLOWING WARNING COULD RESULT IN INJURY.
PLACING TOOL IN SERVICE
Always install, operate, inspect and maintain
this product in accordance with all applicable
standards and regulations (local, state, country,
federal, etc.).
Compressed air models always use clean, dry
air at 90 psi (6.2bar/620kPa) maximum air
pressure at the inlet. Higher pressure may
result in hazardous situations including
excessive speed, rupture, or incorrect output
torque or force.
Electric models must always utilize proper
gauge, and rated electrical cords with correct
connections.
Be sure all hoses and fittings are the correctly
sized and secured.
Ensure an accessible emergency shut off has
been installed in the air or electrical supply line.
Make others aware of its location.
Do not use damaged, frayed, or deteriorated air
hoses and fittings.
Always use proper gauge electrical cords with
correct connections. (When applicable.)
Electric models must not use damaged, frayed, or
deteriorated electrical cords and connections.
Keep clear of whipping air hoses. Shut off the
compressed air before approaching a whipping
hose.
Always turn off and disconnect the tool from its
power supply before installing, removing or
adjusting any accessory, or before performing
any maintenance on the tool.
Do not lubricate tools with flammable or volatile
liquids such as kerosene, diesel or jet fuel. Use
only recommended lubricants.
Keep work area clean, uncluttered, ventilated and
illuminated.
Keep all electrical connections clear of water or
other liquids. (When applicable.)
Do not operate the machine while flammable or
volatile liquids such as gasoline, diesel or jet fuel
are present. Failure to do so can result in
explosion. (When applicable.)
Do not remove any labels. Replace any damaged
label.
USING THE TOOL
Always wear protection when operating or
performing maintenance on this tool.
Always wear hearing protection when operating
this tool.
Always use Personal Protective Equipment
appropriate to the tool used and material
worked. This may include dust mask or other
breathing apparatus, safety glasses, ear plugs,
gloves, apron, safety shoes, hard hat and other
equipment,
Prevent exposure and breathing of harmful dust
and particles created by power tool use:
- Some dust created by power sanding, sawing,
and grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
- Lead from lead based paints,
- Crystalline silica from bricks and cement and
other masonry products, and
- Arsenic and chromium from chemically treated
lumber
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are
specially designed to filter out microscopic
particles.
Keep others a safe distance from your work area,
or ensure they use appropriate Personal
Protective Equipment.
This tool is not designed for working in explosive
environments, including those caused by fumes
and dust, or near flammable materials.
NOTICE
WARNING

Electrically powered tools are not insulated
against electric shock.
Be aware of buried, hidden or other hazards in
your work environment. Do not contact or
damage cords, conduits, pipes, or hoses that
may contain electrical wires, explosive gases or
harmful liquids.
Keep hands, loose clothing, long hair and
jewelry away from working end of tool.
Power tools can vibrate in use. Vibration,
repetitive motions or uncomfortable positions
may be harmful to your hands and arms. Stop
using any tool if discomfort, tingling feeling or
pain occurs. Seek medical advices before
resuming use.
Keep body stance balanced and firm. Do not
overreach when operating this tool. Anticipate
and be alert for sudden changes in motion,
reaction torques, or forces during startup and
operation.
Tool and/or accessories may briefly continue
their motion after throttle is released,
To avoid accidental starting –ensure tool in
“off” position before applying air pressure or
connecting to electricity. Avoid throttle when
carrying, and release throttle with loss of air or
electricity.
Ensure work pieces are secure. Use clamps or
vises to hold work piece whenever possible.
Do not carry or drag the tool by the hose or
power cord.
Do not use power tools when tired, or under the
influence of medication, drugs, or alcohol.
Never us a damaged or malfunctioning tool or
accessory,
Do not modify the tool, safety devices, or
accessories.
Do not use this tool for purposed other than
those recommended.
Use accessories recommended by Novatek
Corp.
Never operate a tool with an accessory unless it
is properly installed and the tool is held firmly
against the work,
Always use a retainer, when furnished, in
addition to proper barriers to protect persons in
surrounding or lower areas from possible
ejected accessories.
When wearing gloves and operating models
with inside trigger, always be sure that the
gloves will not prevent the trigger from being
released.
Wear safety shoes, hard hat, safety goggles,
gloves, dust mask and any other appropriate
protective clothing while operating the tool.
Do no indulge in horseplay. Distraction can
cause accidents.
Keep hands and fingers away from the throttle
lever until it is time to operate the tool.
Never rest the tool on your foot.
Never point the tool at anyone.
Compressed air is dangerous. Never point an air
hose at yourself or others.
Never blow clothes free of dust with compressed
air.
Be sure all hose connections are tight. A loose
hose not only leaks but can come completely off
the tool and while whipping under pressure, can
injure the operator and other in the area. Attach
safety cables to all hosed to prevent injury in case
a hose is accidentally broken.
Never disconnect a pressurized air hose. Always
turn off the air supply and bleed the tool before
disconnecting a hose.
When applicable, the operator must keep limbs
and body clear of the chisel. If a chisel breaks,
the tool with the broken chisel projecting from the
tool will suddenly surge forward.
Do not ride the tool with one leg over the handle.
Injury can result if the chisel breaks while riding
the tool.
Know what is underneath the material being
worked. Be alert for hidden water, gas, sewer,
telephone or electric lines.
Use only proper cleaning solvents to clean parts.
Use only cleaning solvents which meet current
safety and health standards. Use cleaning
solvents in a well ventilated area.
Do not flush the tool or clean any parts with diesel
fuel. Diesel fuel residue will ignite in the tool
when the tool is operated, causing damage to
internal parts. When using models with outside
triggers or throttle levers, take care when setting
the tool down to prevent accidental operation.
Do not operate the tool with broken or damaged
parts.
Never start the tool when it is lying on the ground.
This tool is not designed for working in explosive

SECTION V
PLACING IN OPERATION

8
This tool is used for the removal of rust, corrosion, mill scale, protective coatings, body filler, adhesive labels, etc.
1. Always use suitable sealing material to fasten the connection of the pneumatic hose to the RotoStrip.
2. There are two sizes of abrasive brushes to choose from; 11mm or 23mm straight or bent bristle brushes along with
23mm erasers and coating removal wheels.
Straight Brush
Bent Brush
Eraser Wheel
Coating Removal Wheel
3. NEVER place an 11mm abrasive into a 23mm hub or vice versa. This can cause damage to the machine and operator.
4. Start the tool by moving the safety stop forward and depressing the throttle level. The throttle level will return to its initial
position when it is released.
5. NEVER operate the tool while not in contact with the work surface or if there is the possibility of bodily contact with the
rotating hub.
6. Hold the tool by the body and the vertical handle at the same time. This is to ensure proper substrate removal and
secure handling of the tool during operation.
7. Work only with minimum surface pressure and even movements across surface. Excess pressure can reduce the
desired results and wear abrasives prematurely.
