www.iqpowertools.com
General
This section describes the machine’s safety equipment,
its purpose, and how checks and maintenance should be
carried out to ensure that it operates correctly.
VIBRATION DAMPING SYSTEM
Your machine is equipped with a vibration damping
system that is designed to minimize vibration
and make operation easier.
The machine’s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine’s handle unit.
The engine body, including the cutting equipment, is
insulated from the handles by vibration damping units.
Regularly check the vibration damping units for cracks
or deformation.
Make sure the vibration damping units are securely
attached to the engine unit and handle unit.
Keep the handles clean and dry.
STOP SWITCH
Use the stop switch to switch o the engine.
O = OFF / I = ON
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
MUFFLER
The muer is designed to keep noise levels to a
minimum and to direct exhaust fumes away from
the user.
IMPORTANT INFORMATION
For muers it is very important that you follow the
instructions on checking, maintaining and servicing
your machine. See instructions under the heading
Checking, maintaining and servicing the machine’s
safety equipment. Never use a machine that has a faulty
muer. Regularly check that the muer is securely
attached to the machine.
WARNING! NEVER USE A MACHINE THAT HAS
FAULTY SAFETY EQUIPMENT
MACHINE’S SAFETY EQUIPMENT
WARNING!
THE MUFFLER GETS VERY
HOT IN USE AND REMAINS SO
FOR A SHORT TIME AFTERWARDS. DO NOT TOUCH THE
MUFFLER IF IT IS HOT!
WARNING!
THE EXHAUST FUMES FROM
THE ENGINE ARE HOT AND
MAY CONTAIN SPARKS WHICH CAN START A FIRE. NEVER
START THE MACHINE INDOORS OR NEAR COMBUSTIBLE
MATERIAL!
WARNING!
THE INSIDE OF THE MUFFLER
CONTAIN CHEMICALS THAT
MAY BE CARCINOGENIC. AVOID CONTACT WITH THESE
ELEMENTS IN THE EVENT OF A DAMAGED MUFFLER.
THROTTLE LOCKOUT
The throttle lockout is designed to prevent accidental
operation of the throttle.
When the throttle lockout
(A) is pressed in this
releases the throttle trigger
(B). The throttle lockout
remains pressed in as long
as the throttle trigger is
pressed. When the grip
on the handle is released
the throttle trigger and
the throttle lockout both
return to their original
positions. This is controlled by two independent return
spring systems. This means that the throttle trigger is
automatically locked in the idle position.
Make sure the throttle trigger is locked at the idle
setting when the throttle lockout is released.
Press the throttle lockout and make sure it returns to
its original position when you release it.
Check that the throttle trigger and throttle lockout
move freely and that the return springs work properly.
Start the power cutter and apply full throttle. Release
the throttle trigger and check that the cutting blade
stops and remains stationary. If the cutting blade
rotates when the throttle is in the idle position you
should check the carburetor’s idle adjustment.

iQPC912VSK
Operator’s Manual
888-274-7744
www.iqpowertools.com
SAFETY
Ensure that the working area is suciently illuminated to
create a safe working environment.
• Do not move the machine when the cutting
equipment is rotating.
• Always ensure you have a safe and stable
working position.
• Make sure that no pipes or electrical cables
are routed in the area to be cut.
CUTTING
• Start cutting with the machine running at
maximum speed.
• Always hold the machine in a firm grip with
both hands.
• Hold it so that the thumbs and fingers grip
round the handles
GENERAL CUTTING TECHNIQUE
The technique described below is of a general character.
Check information for each blade regarding individual
cutting characteristics.
• Support the work piece in such a way that it is
possible to predict what will happen, and so
that the cut remains open while cutting.
• Check that the blade is not in contact with
anything when the machine is started
• Always cut at maximum speed.
• Start cutting smoothly, allowing the machine
to work without forcing or pressing in the
blade. Move the blade slowly follow the cutting
direction arrows indicated on the blade guard.
Always cut in a downward direction to
ensure proper dust capture. It’s important to
keep the dust guard against the material
being cut for best results.
• Do not use the upper quarter of cutting
blade to cut. If the upper quarter of the
cutting blade is applied to material, the
machine can be flung back toward the
operator with great force. The machine and
the rotating cutting blade can cause severe
injury.
• Feed down the machine in line with the blade.
Pressure from the side can damage the blade
and is very dangerous.
HOW TO AVOID KICKBACK
What is kickback?
The word kickback is used to describe the sudden
reaction that causes the power cutter and cutting blade
to be thrown from an object when the upper quadrant of
the blade, known as the kickback zone or NO Cut Zone,
touches an object.
GENERAL RULES
• Never start to cut with the upper quadrant of
the blade as shown in the figure, also known
as the No Cut Zone.
• Always hold the machine in a firm grip with
both hands. Hold it so that the thumbs and
fingers grip round the handles.
• Keep a good balance and a firm foothold.
• Always cut at maximum recommended speed.
• Stand at a comfortable distance from the
work piece.
• Take care when inserting the blade in an
existing cut.
• Never cut above shoulder height.
WARNING!
KICKBACK CAN HAPPEN VERY
SUDDENLY AND VIOLENTLY;
KICKING THE POWER CUTTER AND CUTTING BLADE BACK AT
THE USER. IF THIS HAPPENS WHEN THE CUTTING BLADE IS
MOVING IT CAN CAUSE VERY SERIOUS, EVEN FATAL INJURIES.
IT IS VITAL YOU UNDERSTAND WHAT CAUSES KICKBACK AND
THAT YOU CAN AVOID IT BY TAKING CARE AND USING THE
RIGHT WORKING TECHNIQUE.

iQPC912VSK
Operator’s Manual
888-274-7744
www.iqpowertools.com
• Be alert to movement of the work piece or
anything else that can occur, which could
cause the cut to close and pinch the blade.
PULL IN
Pull in occurs when the disc’s lower section suddenly
stops or when the cut closes. (To avoid, see the heading
”Basic rules” and ”Jamming/rotation”, here below.)
PINCHING/ROTATION
If the cut is pressed together this can lead to jamming.
The machine can be pulled down suddenly
with a very powerful force.
HOW TO AVOID PINCHING
Support the work piece in such a way that the cut
remains open during the cutting operation and
when the cut is finished.
Cutting Blades
GENERAL
Use only diamond blades approved for cutting concrete
and masonry.
Do not cut metal materials.
Always remove the cutting blade when the machine is
transported.
SAFETY
Make sure that the right spacer bushing is used for the
cutting blade to be fitted on the machine.
See the instructions under the heading Assembling the
cutting blade.
High-quality blades are often most economical. Lower
quality blades often have inferior cutting capacity and
a shorter service life, which results in a higher cost in
relation to the quantity of material that is cut.
DIAMOND BLADES
Diamond blades consist of a steel body provided with
segments that contain industrial diamonds. When
using diamond blades make sure that it rotates in the
direction indicated by the arrow on the blade.
Always use a sharp diamond blade. Sharpen the blade
by cutting in a soft material such as sandstone or brick.
Diamond blades are available in several hardness
classes. A “soft” diamond blade has a relatively short
service life and large cutting capacity. It is used for hard
materials such as granite and hard concrete. A “hard”
diamond blade has a longer service life and reduced
cutting capacity, and should be used for soft materials
such as brick and asphalt.
MATERIAL
Diamond blades are ideal for masonry, concrete and
other composite materials. Diamond blades
are not recommended for cutting metal. The iQ
PowerCutter™ should never be used to cut metal.
DIAMOND BLADES FOR DRY CUTTING
Diamond blades for dry cutting are a new generation of
blades that do not require water cooling.
However, the blades will still be damaged by excessive
heat. It is most economical to allow the blade to cool by
simply lifting it out from the cut every 30–60 seconds
and letting it rotate in the air for 10 seconds.
Check that the blade is approved for the same or higher
speed as stated in the operator’s manual.
Never use a cutting blade with a lower speed rating
than that of the power cutter.
Ensure the blade it not cracked or damaged
in any other way.

STEP UP, ADJUSTMENTS, & OPERATION
SHARPENING DIAMOND BLADES
Diamond blades can become dull when the wrong
feeding pressure is used or when cutting certain
materials such as high strength concrete. Working with
a blunt diamond blade causes overheating,
which can result in the diamond segments coming loose.
Sharpen the blade by cutting in a soft material such as
sandstone or brick.
BLADE VIBRATION
The blade can become out-of-round and vibrate if an
excessive feed pressure is used.
A lower feed pressure can stop the vibration.
Otherwise replace the blade. The blade must be of the
recommended type for the material to be cut.
CHECKING THE DRIVE AXLE AND FLANGE WASHERS
Check that the threads on the drive shaft are
undamaged.
Check that the contact surfaces on the blade and the
blade thrust washers are undamaged, of the correct
dimension, clean, and that they run properly on the drive
axle.
Do not use warped, notched, indented or dirty blade
thrust washers.
Do not use dierent dimensions of blade thrust washers.
FITTING THE CUTTING BLADE
iQ Diamond Blades are approved for hand-held power
cutters. Blades are manufactured with 1” (25.4mm)
diameter center hole .
The blade is placed on the bushing “C” between the inner
thrust washer “A” and the outer thrust washer “B” The
thrust washer is turned so that it fits on the axle.
Tightening torque for the bolt holding the blade is: 15-25
Nm (130-215 in.lb). The shaft can be locked using a
screwdriver, steel pin or the like.
This is slid in as far as possible. The blade is tightened
clockwise.
When a diamond blade is mounted on the power cutter
make sure that the diamond blade will rotate in the
direction indicated by the arrow on the blade.
When the blade is replaced with a new one, check the
flange washers and the drive axle. See instructions
under the heading Checking the drive axle and blade
thrust washers.
GUARD FOR THE BLADE
The guard must always be fitted on the machine.
RETRACTING DUST GUARD
The lower retracting dust guard should be inspected for
damage and wear to ensure smooth operation.
WARNING!
A CUTTING BLADE MAY BURST
AND CAUSE INJURY TO THE
OPERATOR. NEVER USE A CUTTING BLADE AT A LOWER
SPEED RATING THAN THAT OF THE POWER CUTTER. NEVER
USE A CUTTING BLADE FOR ANY OTHER MATERIALS THAN
THAT IT WAS INTENDED FOR.
WARNING!
OVEREXPOSURE TO VIBRATION
CAN LEAD TO CIRCULATORY
DAMAGE OR NERVE DAMAGE IN PEOPLE WHO HAVE
IMPAIRED CIRCULATION. CONTACT YOUR DOCTOR IF
YOU EXPERIENCE SYMPTOMS OF OVEREXPOSURE TO
VIBRATION. THESE SYMPTOMS INCLUDE NUMBNESS,
LOSS OF FEELING, TINGLING, PRICKING, PAIN, LOSS OF
STRENGTH, CHANGES IN SKIN COLOR OR CONDITION.
THESE SYMPTOMS NORMALLY APPEAR IN THE FINGERS,
HANDS OR WRISTS.

FUEL MIXING INSTRUCTIONS
FUEL
CAUTION! The machine is equipped with a two-stroke
engine and must always be run using a mixture of petrol
and two stroke engine oil. It is important to accurately
measure the amount of oil to be mixed to ensure that the
correct mixture is obtained. When mixing small amounts
of fuel, even small inaccuracies can drastically aect the
ratio of the mixture.
Use good quality unleaded or leaded gasoline.
The lowest octane recommended is 90 (RON). If you run
the engine on a lower octane grade than 90 so-called
knocking can occur. This gives rise to a high engine
temperature, which can result in serious engine damage.
TWO-STROKE OIL
• For best results and performance use
two-stroke engine oil, which is specially
formulated for air cooled two-stroke engines.
• Never use two-stroke oil intended for water-
cooled engines, sometimes referred to as
outboard oil (rated TCW).
• Never use oil intended for four-stroke engines.
MIXING RATIO
1:50 (2%) with two-stroke oil.
Gas, gallons Two-stroke oil, ounces
2% (1:50)
12.6 (1/3 cup)
513 (1-2/3 cup)
10 26 (3-1/4 cups)
15 39 (4-7/8 cups)
20 52 (6-1/2 cups)
MIXING
• Always mix the gas and oil in a clean container
intended for fuel.
• Always start by filling half the amount of the
gas to be used. Then add the entire amount
of oil. Mix (shake) the fuel mixture. Add the
remaining amount of gas.
• Mix (shake) the fuel mixture thoroughly before
filling the machine’s fuel tank. Do not mix
more than one month’s supply of fuel at a time.
• If the machine is not used for some time the
fuel tank should be emptied and cleaned.
FUELING
• Keep the handle dry and free from oil and fuel.
• Ensure that the fuel is well mixed by shaking
the container before filling the tank.
• Always exercise care when refilling the fuel.
Move the machine at least 10 feet from the
fueling area before it is started. Check that the
fuel cap is tightened correctly.
• Clean around the fuel cap. Clean the fuel tank
regularly. The fuel filter should be changed at
least once a year. Contamination in the tanks
causes malfunction.
WARNING!
WARNING! TAKING THE
FOLLOWING PRECAUTIONS,
WILL LESSEN THE RISK OF FIRE: DO NOT SMOKE OR
PLACE HOT OBJECTS NEAR FUEL. ALWAYS SHUT OFF THE
ENGINE BEFORE REFUELING. WHEN REFUELING, OPEN THE
FUEL CAP SLOWLY SO THAT ANY EXCESS PRESSURE IS
RELEASED GENTLY. TIGHTEN THE FUEL CAP CAREFULLY
AFTER REFUELING. ALWAYS MOVE THE MACHINE AWAY
FROM THE REFUELING AREA BEFORE STARTING..
WARNING!
UNDER ALL CIRCUMSTANCES
AVOID GRINDING USING THE SIDE
OF THE BLADE; IT WILL ALMOST CERTAINLY BE DAMAGED,
BREAK AND CAN CAUSE IMMENSE DAMAGE. ONLY USE THE
CUTTING SECTION.
DO NOT PULL THE POWER CUTTER TO ONE SIDE, THIS
CAN CAUSE THE BLADE TO JAM OR BREAK RESULTING
IN INJURY TO PEOPLE.
CAUTION!
CAUTION! IF THE DIAMOND
BLADE SHOWS SIGNS OF
FATIGUE CRACKING, REPLACE THE BLADE BEFORE
STARTING WORK.

MAINTENANCE & TROUBLE SHOOTING
OVERVIEW
The iQPC912VSK power cutter is a innovative tool
that integrates a power cutter and a dust collection
vacuum and filtration system. Because the IQPC912VSK
incorporates a vacuum system the operator needs
to clearly understand how the system works, proper
cutting techniques and managing the filtration and
debris dumping procedure. Like any professional tool
understanding the proper operational procedures
is essential to the safe and eective use of the
iQPC912VSK power cutter.
PROPER CUTTING TECHNIQUE
Always cut with the bottom quadrant of the blade known
as the Clean Cut Zone. Cut in a downward direction or
following the indicated cutting direction arrows on the
lower blade guard.
Never cut with the upper quadrant of the blade known as
the No Cut Zone.
DUST GUARD
It’s important to keep the Dust Stop and retracting
Dust Guard against the material being cut for proper
dust capture.
IF YOU SEE DUST ESCAPING
(A) If you see dust escaping from the top of the blade
guard, that means vacuum airflow has been restricted.
The following items need to be checked.
1. The spin filter needs to be spun more often.
2. The filter cleaning tab is not engaging the
filter pleats enough to clean properly. You
should hear a popping sound each time the
filter tab pops over a filter pleat.
3. The lower dust chamber needs to be emptied
of dust and free of dust and debris blockage.
4. The filter may be past its operational life of
100 hours or 90 days.
(B) If you see dust escaping from between the engine
and filter housing the following needs to be checked.
1. The filter may be past its operational life of
100 hours or 90 days and should be replaced.
WARNING!
TO AVOID POTENTIAL KICKBACK
INJURY AND DUST EXPOSURE
DO NOT CUT WITH THE UPPER QUADRANT OF THE BLADE.
