General Safety Rules
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and
instructions may result in electric shock,  re and/or serious injury.
Save all warnings and instructions for future reference.
The term“power tool”in the warnings refers to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1. WORK AREA SAFETY
a. Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b. Do not operate power tools in explosive atmospheres, such as in the presence of  ammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
d. Never leave the electric power tool unattended. Only leave the machine when the tool in use has come
to a complete standstill.
2. ELECTRICAL SAFETY
a. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools. Unmodi ed plugs and matching outlets will reduce risk of
electric shock.
b. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk
of electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk
of electric shock.
e. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric shock.
f. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of electric shock.
3. PERSONAL SAFETY
a. Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the in uence of drugs, alcohol or medication. A
moment of inattention while operating power tools may result in serious personal injury.
b. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce
personal injuries.

GB
4
c. Prevent unintentional starting. Ensure the switch is in the o-position before connecting to power
source and/or battery pack, picking up or carrying the tool. Carrying power tools with your  nger on
the switch or energising power tools that have the switch on invites accidents.
d. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result in personal injury.
e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
f. Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g. If devices are provided for the connection of dust extraction and collection facilities, ensure these
are connected and properly used. Use of dust collection can reduce dustrelated hazards.
h. Do not let familiarity gained from freuquent use of tools allow you to become complacent and
ignore, tool safety principles. A careless action can cause severe injury within a fraction of a second.
4. POWER TOOL USE AND CARE
a. Do not force the power tool. Use the correct power tool for your application. The correct power tool
will do the job better and safer at the rate for which it was designed.
b. Do not use the power tool if the switch does not turn it on and o. Any power tool that cannot be
controlled with the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source and/or battery pack from the power tool before making
any adjustments, changing accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
d. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the
power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of
untrained users.
e. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and
any other condition that may aect the power tool‘s operation. If damaged, have the power tool
repaired before use. Many accidents are caused by poorly maintained power tools.
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g. Use the power tool, accessories and tool bits etc. in accordance with these instructions taking into
account the working conditions and the work to be performed. Use of the power tool for operations
dierent from those intended could result in a hazardous situation.
h. Keep handles dry, clean and free of oil and grease. Slippery handles do not allow for safe handling and
control of the tool in unexpected situations.
5. SERVICE
a. Have your power tool serviced by a quali ed repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
b. Only use original parts for repair and maintenance. The use of incompatible accessories or spare parts
can result in electric shocks or other injuries.

Cut-o machine safety warnings
• The guard provided with the tool must be securely attached to the power tool and positioned for
maximum safety, so the least amount of wheel is exposed towards the operator. Position yourself
and bystanders away from the plane of the rotating wheel. The guard helps to protect operator from
broken wheel fragments and accidental contact with wheel.
• Use only diamond cut-o wheels for your power tool. Just because an accessory can be attached to
your power tool, it does not assure safe operation.
• The rated speed of the accessory must be at least equal to the maximum speed marked on the
power tool. Accessories running faster than their rated speed can break and y apart.
• Wheels must be used only for recommended applications. For example: do not grind with the side
of cut-o wheel. Abrasive cut-o wheels are intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
• Always use undamaged wheel anges that are of correct diameter for your selected wheel. Proper
wheel anges support the wheel thus reducing the possibility of wheel breakage.
• Do not use worn down reinforced wheels from larger power tools. Wheels intended for larger power
tools are not suitable for the higher speed of a smaller tool and may burst.
• The outside diameter and the thickness of your accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
• The arbour size of wheels and anges must properly t the spindle of the power tool. Wheels and
anges with arbour holes that do not match the mounting hardware of the power tool will run out of
balance, vibrate excessively and may cause loss of control.
• Do not use damaged wheels. Before each use, inspect the wheels for chips and cracks. If power
tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and
installing the wheel, position yourself and bystanders away from the plane of the rotating wheel
and run the power tool at maximum no load speed for one minute. Damaged wheels will normally
break apart during this test time.
• Wear personal protective equipment. Depending on application, use face shield, safety goggles or

safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and shop apron capable
of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping
ying debris generated by various operations. The dust mask or respirator must be capable of ltrating
particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing
loss.
• Keep bystanders a safe distance away from work area. Anyone entering the work area must wear
personal protective equipment. Fragments of workpiece or of a broken accessory may y away and
cause injury beyond immediate area of operation.
• Hold the power tool by insulated gripping surfaces only, when performing an operation where the
cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live”
wire may make exposed metal parts of the power tool“live”and could give the operator an electric shock.
• Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning wheel.
• Never lay the power tool down until the accessory has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of your control.
• Do not run the power tool while carrying it at your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the accessory into your body.
• Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause electrical hazards.
• Do not operate the power tool near ammable materials. Sparks could ignite these materials.
Kickback and related warnings
• Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging causes
rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool to be forced in the
direction opposite of the wheel’s rotation at the point of the binding. For example, if an abrasive wheel
is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can
dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either
jump toward or away from the operator, depending on direction of the wheel’s movement at the point
of pinching. Abrasive wheels may also break under these conditions. Kickback is the result of power
tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper
precautions as given below.
• Maintain a rm grip on the power tool and position your body and arm to allow you to resist
kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or
torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper
precautions are taken.
• Never place your hand near the rotating accessory. Accessory may kickback over your hand.
• Do not position your body in line with the rotating wheel. Kickback will propel the tool in direction
opposite to the wheel’s movement at the point of snagging.
• Use special care when working corners, sharp edges, etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause
loss of control or kickback.
• Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such blades create frequent kickback and loss of control.
• Do not“jam”the cut-o wheel or apply excessive pressure. Do not attempt to make an excessive

7
GB
depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding the
wheel in the cut and the possibility of kickback or wheel breakage.
• When wheel is binding or when interrupting a cut for any reason, switch o the power tool and
hold the power tool motionless until the wheel comes to a complete stop. Never attempt to
remove the cut-o wheel from the cut while the wheel is in motion otherwise kickback may occur.
Investigate and take corrective action to eliminate the cause of wheel binding.
• Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully
re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
• Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece
near the line of cut and near the edge of the workpiece on both sides of the wheel.
• Use extra caution when making a “pocket cut” into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
Cut-Off Machine Safety Warnings - Additional Safety Rules
WARNING: Avoid cutting in the upper quadrant of the
blade, especially when beginning the cut. This area is
highly likely to lead to kickback.
WARNING: When cutting plastics, do not allow the plastic
to melt. If the plastic melts, it can stick to the blade,
leading to kickback.
ELECTRICAL CONNECTION
The network voltage must conform to the voltage indicated on the tool name plate. Under no
circumstances should the tool be used when the power supply cable is damaged. A damaged cable
must be replaced immediately by an authorized Customer Service Center. Do not try to repair the
damaged cable yourself. The use of damaged power cables can lead to an electric shock.
WARNING: Never operate a damaged machine. Always tag a damaged machine and take it out of
service until repairs can be made.
WARNING: These machines are equipped with a Portable
Residual Current Device (PRCD) also known as a Ground Fault
Circuit Interrupter (GFCI). Always use this device whenever
using the machine to reduce the risk of shock hazards.
Always position the PRCD as close as possible to the power
source. Test and reset the PRCD device before each use. Press
the“Test” button to test. Press the“Reset” button to energize
the circuit to the machine.

About Diamond Blades
Diamond blades consist of a steel core with diamond segments added to its periphery.
Diamond blades are available for different hardnesses of masonry materials, stone, concrete, reinforced
concrete, etc.
Some diamond blades are designed to be used wet only, while others are designed to be allowed to be used
dry. Refer to the blade manufacturer’s instructions.
Generally speaking, even if the blade is specified as a dry type blade, diamond tools always work better when
wet, and dry cutting should be limited to situations in which water cannot or should not be used. Water will
prevent the blade from overheating, greatly reduce the amount of harmful dust created by cutting, remove
the slurry from the cut, and extend the life of the blade. Dry cutting of very hard materials such as porcelain or
reinforced concrete will lead to rapid tool wear and possible failure.
The diamond impregnated segments operate on a principle of controlled erosion. The bond matrix holding
the diamonds is continually worn away by abrasion with the workpiece, exposing the harder diamonds to
stand proud from the bond matrix. Blades made for cutting harder materials will have a softer bond, allowing
the diamonds project more aggressively (but will not last as long). Blades made for cutting softer, abrasive
materials will have a harder bond, allowing them to resist the abrasiveness of the material and to last longer.
With enough erosion of the bond matrix (the diamonds not exposed) and the blade becomes dull . This is
called glazing . If the blade seems to refuse to cut anymore, it is glazed.
See below: ”Sharpening a Glazed Blade”
Never use a sharp motion or the blade will be damaged. Conversely, don’t feed too gently or the diamond
segments will become glazed. Keep the blade steadily working.
Take great care to keep the blade perpendicularly aligned to the kerf. If the blade is crooked, it will easily bind.
When cutting reinforced concrete, if embedded steel is encountered, take special care. Reduce the feed
pressure by about 1/3 and let the blade go at its own pace, if there is too much vibration the blade may be
destroyed. Once the steel is passed, continue normally.
NOTE: Never use a wet-type diamond blade without water. It will overheat and be destroyed.
NOTE: When using dry blades, do not allow them to overheat. It is best to cut no longer than about 60
seconds at a time, with 10 second running in air cool down times in between.
Always mount the blade with the arrow matching the direction of rotation of the machine (A direction arrow is
marked on the blade guard).
WARNING: Never use blades for cutting a material other than the material they were intended for.
SHARPENING A GLAZED BLADE
Diamond blades may become glazed (dull). Once the diamond segments are glazed, the blade’s cutting
performance will degrade and the segments will overheat. To resharpen the blade, turn down the water
feed and make a few cuts in a very soft, abrasive material such as brick or an alumina oxide or silicon carbide
dressing stone.

MOUNTING THE BLADE
First make sure that the machine is unplugged.
Then, using the 17mm combination wrench, engage the arbor bolt and turn the arbor while pressing on the
arbor lock . When the arbor reaches the right position, the arbor lock will be allowed to engage. Then the arbor
bolt may be loosened and the plain outer flange may be removed.
The inner flange of this machine is 1" (25.4mm). Check the inner flange to ensure that the size matches the bore
of the blade .
Inspect the blade before use. It must not be cracked, warped or damaged in any way that would cause a hazard
in operation. Loose diamond segments can be ejected at high speed, causing possible injury. Always check
that the diamond segments are not under cut. If the diamond segments are thinner or nearly thinner than the
blade core, the kerf will be too tight fitting and could easily lead to kickback.
Ensure that the flanges and blade bore are clean and undamaged and that everything fits properly. The flanges
may not be used if they are warped, the surface is uneven, burred or if they are dirty. The arbor bolt and
arbor threads must be undamaged. Inspect the blades for segment damage, arbor hole damage or any other
damage which could cause hazardous operation.
The protruding edge of the inner flange should be facing the blade. Then mount the blade to the inner flange
and add the outer flange. Add the arbor bolt and tighten to 15-25 Nm.
WARNING: Do not attempt to mount a blade which does not match the mounting hardware. It will lead
to eccentric running and vibration which will be uncontrollable.
ADJUSTING THE BLADE GUARD
The blade rotates clockwise when viewed from the arbor end. Therefore, most of the cutting debris, sparks
and slurry is thrown to the rear. So the blade guard should be adjusted so that the rear edge is flush with the
workpiece.
TO ADJUST
First pull out the locking lever against the spring tension, then rotate the
blade guard to the desired position. Allow the locking lever to engage the
nearest slot in the guard to lock it into position.
BLADE GUARD BRUSH
There is a removable brush at the rear of the guard to help contain sparks, dust, debris and slurry. To install,
simply push the brush into the slot in the bottom of the dust port bracket until it clicks in place. This brush may
be pulled straight out to replace when worn.
Blade Guard Locking Lever

11
GB
SPLASH GUARD
The spring-loaded splash guard is useful to help to contain slurry which splashes toward the back.
To install, simply clip into place on the back of the dust port bracket. To remove, tilt upward to pop free.
If the splash guard is not needed, such as when cutting dry, it may be clipped up out of the way. Simply engage
the male clip on the flap with the female clip on the mount. Unclip to release.
WATER CONNECTION
Water is a basic requirement for diamond sawing with wet-type diamond blades. The water serves as a
coolant to avoid the working surface of the diamond segments from
overheating.
Water also keeps down dust and flushes away abrasive particles.
WARNING: Always use the PRCD (GFCI) when operating with
water
WARNING: Never allow water to enter the motor. It could lead to
an electric shock.
WARNING: Check all connections of the water feed system to ensure there are no leaks. Inspect hoses
and other critical parts which could deteriorate.
WARNING: The maximum water pressure should not exceed 70 psi (4 bar).
Use a water collector with a wet vacuum to collect cooling water if nearby objects could be damaged by water.
The water feed system is built into the machine. To connect with the water supply, first pull the quick-release
collar to remove the female side of the water coupling. Then unscrew the nut and engage the coupling to the
water hose. Now reconnect the water coupling to the male water feed valve. Press it until it clicks.
The water flow is controlled by the water feed valve. The water to the blade may be finely adjusted to the
required amount.
NOTE: Contaminants in the water supply can easily plug up the fine water nozzles in the blade guard.
Ensure that the supply water is clean. If you find that there is no water flow to the blade, then clean out
the water feed system on the machine.
GUIDE ROLLER ASSEMBLY
The guide rollers make it easier to keep the blade plane perpendicular to
the workpiece. To install, slacken the butterfly bolt slightly and engage the
four claws with the four eyelets on the bottom of the motor housing, then
tighten the butterfly bolt.

OVERLOAD PROTECTION, OVERHEAT PROTECTION
Overload & Load Warning Lamp
When full load is reached, the load warning lamp will flash red. If full load
is exceeded and sustained for too long, the motor will shut down and the
load warning lamp will glow solid red. In this case, the motor must be first
shut off and then restarted.
Overheat Thermal Protection
If the temperature of the motor gets too high, the thermal protection
will shut the motor down. The switch must be first shut off and then restarted. When this happens, do not
immediately start cutting after restarting the motor. Always run the machine at no load for a few minutes to
return to a normal operating temperature before continuing.
CAUTION: The motor will be damaged if it is repeatedly overloaded or overheated. Always cool the
motor by running at no load for a few minutes whenever it stops from either overheat or overload.
OPERATION
How to hold the machine
• Always hold the machine with both hands, with the right hand on the main handle and with the left
hand on the side handle. (This applies even if the
operator is left-handed)
• Do not stand directly in line with the blade.
Rather, stand in such a way that, if it kicks back,
you will not be in the path of the blade.
• Never lean over the blade path. That would put
your body in line with the blade if it kicks back.
• Do not cut above shoulder height.
• Never cut while standing on a ladder or other unstable platform.
Before cutting
• Check the area where the cut is to be made to ensure that it is clear of objects which could cause the
operator to stumble.
• Before cutting, it is sometimes useful to mark the line of cut with chalk or the like. For straight cutting, a
wood plank is also useful in guiding the machine to make a straight cut.
• Ensure that all bystanders are at a safe distance.
• Ensure that all safety equipment is in place.

Proper Support for the Workpiece
• Support the workpiece on in such a way that the
kerf will not pinch down on the blade.
• Secure the workpiece so that it will not roll, slip
away or move due to vibration while cutting
• The cutting sequence is important when making
cutouts. Always make the last cut in a way that
avoids the blade being pinched. Thus, make the bottom horizontal cut first, then the sides and finally
make the top horizontal cut last.
• Make note of the weight of the workpiece and the direction which it will fall when it is cut through.
• Whenever there is a situation where severing the workpiece will cause a hazardous situation, leave a tab
of material intact and finish off the operation with a chisel or the like.
Cutting Technique
• Holding the machine with both hands to resist the start up torque, press the release button and then
squeeze the trigger switch.
• Allow the machine to reach full speed before contacting the workpiece.
• Adjust the water flow as needed by turning the water feed valve.
• Then gently begin the cut with the rear portion of the blade until the kerf is established. Make the first
cut in the forward direction (so that you can see
the line of cut). Then make following cuts in the
backward direction.
• Do not try to cut too much depth in one pass.
Never exceed about 50mm (2”) per pass.
• It’s a good idea to first cut a shallow guiding
groove before proceeding to make the main
cut . If any correction is needed. Lift the blade
and cut slightly ahead and then back into the
existing kerf. Take care to avoid the blade being
pinched.
• In round workpieces, the best technique is to
use a slow, uniform back and forth motion while
cutting with the bottom quadrant of the blade.
• Do not allow the machine to bog down. Limit
your feed pressure to keep the blade spinning at
high speed.
• Never side load the blade in the kerf.
• Concrete cutting is very stressful for the motor: After the cut is finished, it is a good practice to run the
machine at no load for a short time to lower the motor temperature before stopping.
Stopping
Release the trigger to stop the machine. After the trigger is released, the blade will continue spinning for a
time.

WARNING: Do not set the machine down until the blade has stopped turning.
Note: Always ensure the vacuum cleaner's dust bag is not too full. An overfilled dust bag will have
reduced dust collection efficiency which could result in poor dust control.
OPTIONAL DUST SKID (Model C14 only)
The dust skid dramatically improves dust collection for dry cutting.
Note: Do not use for wet cutting, as the slurry will harden inside it and cause it to clog.
To install, first remove the splash guard.
Remove the pivot pin in the dust skid by turning 90 degrees and pulling out. Place the dust skid in place on the
dust port bracket. Line up the holes and insert the pivot pin. The pin locks by a bayonet mount. Turn so that
pin can insert fully, then turn 90 degrees to lock in place. Ensure that it pivots freely. finally, attach the vacuum
hose. Removal is the opposite of mounting.
Note: Always ensure the vacuum cleaner's dust bag is not too full. An overfilled dust bag will have
reduced dust collection efficiency which could result in poor dust control.
MAINTENANCE AND CLEANING
This machine operates in a very harsh environment. The slurry created by wet cutting and the dust created by
dry cutting gets sucked into the motor’s cooling slots and enters the motor. The slurry of brick and concrete
contains salts and other corrosive substances which will severely shorten the life of the motor or cause
electrical shorts if allowed to accumulate.
Therefore, it’s essential for the long life of the tool that it be thoroughly cleaned after each use.
Compressed air should be blown through the machine’s cooling slots at the back of the machine while the
motor is running.
Daily Maintenance
1. Keep the machine clean
2. Check to ensure that the power supply cable is in good
condition.
3. Ensure all screws are tight.
4. Check the condition of all safety equipment such as the blade
guard
5. Check the blade for damage.
Carbon Brushes
The carbon brushes are a normal wearing part and must be replaced when they reach their wear limit. This
machine is equipped with auto-stop carbon brushes. If the machine comes to a stop unexpectedly, the brushes

should be checked. The auto-stop brush design protects the motor by stopping the machine before the carbon
brushes are completely worn out.
Caution: Always replace the brushes as a pair.
To replace
1. Remove the screw and remove the brush cover.
2. Using pliers rotate the brush spring out of the way and slide the old carbon brush out of the brush
holder.
3. Unscrew the screw to remove the brush lead. The old carbon brush may now be lifted away.
4. Install a new brush. Installation is the reverse of removal.
5. Replace the brush cover.
If the replacement of the power supply cord is necessary, this has to be done by the manufacturer or their
agent in order to avoid a safety hazard.
WARNING: All repairs must be entrusted to an authorized service center. Incorrectly performed repairs
could lead to injury or death.
Do not throw electric power tools into the household waste!
In accordance with the European Directive 2002/96/EG on Waste Electrical and Electronic Equipment and
transposition into national law, used electric power tools must be collected separately and recycled in an
environmentally friendly manner.
