General Power Tool Safety
Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for
future reference.
GEB042-5
ANGLE CUTTER SAFETY
WARNINGS
1. 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.
2. Use only bonded reinforced or diamond cut-
off wheels for your power tool. Just because
an accessory can be attached to your power tool,
it does not assure safe operation.
3. 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 fly apart.
4. Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them
to shatter.
5. Always use undamaged wheel flanges that are
of correct diameter for your selected wheel.
Proper wheel flanges support the wheel thus
reducing the possibility of wheel breakage.
6. Do not use worn down reinforced wheels from
larger power tools. Wheels intended for a larger
power tool are not suitable for the higher speed of
a smaller tool and may burst.
7. 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.
8. The arbour size of wheels and flanges must
properly fit the spindle of the power tool.
Wheels and flanges 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.
9. 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.
10. 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 flying debris generated by various
operations. The dust mask or respirator must be
capable of filtrating particles generated by your
operation. Prolonged exposure to high intensity
noise may cause hearing loss.

5
11. 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 wheel
may fly away and cause injury beyond immediate
area of operation.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
18. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
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.
a) Maintain a firm 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.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) 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.
d) 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.
e) 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.
f) Do not “jam” the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or binding
of the wheel in the cut and the possibility of
kickback or wheel breakage.
g) When wheel is binding or when interrupting
a cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never
attempt to remove the 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.
h) 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.
i) 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.
j) 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.
19. Before using a segmented diamond wheel,
make sure that the diamond wheel has the
peripheral gap between segments of 10 mm or
less, only with a negative rake angle.
Additional safety warnings:
20. Be careful not to damage the spindle, the
flange (especially the installing surface) or the
lock nut. Damage to these parts could result
in wheel breakage.
21. Make sure the wheel is not contacting the
workpiece before the switch is turned on.

6
22. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
23. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.
24. Do not leave the tool running. Operate the tool
only when hand-held.
25. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
26. Always be sure that the tool is switched off
and unplugged or that the battery cartridge is
removed before carrying out any work on the
tool.
27. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
28. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
29. Use only flanges specified for this tool.
30. Check that the workpiece is properly
supported.
31. Pay attention that the wheel continues to
rotate after the tool is switched off.
32. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure
operator safety.
33. Do not use the tool on any materials
containing asbestos.
34. Do not use water or grinding lubricant.
35. Ensure that ventilation openings are kept
clear when working in dusty conditions. If it
should become necessary to clear dust, first
disconnect the tool from the mains supply
( use non metallic objects ) and avoid
damaging internal parts.
36. Cutting discs must not be subjected to any
lateral pressure.

dangerous.
Fig.4
Fig.5
CAUTION:
• Use only the Makita wrench to install or remove
the wheel.
OPERATION
CAUTION:
Be sure to pull the tool when cutting a workpiece.
• Use this tool for straight line cutting only. Cutting
curves can cause stress cracks or fragmentation
of the diamond wheel and abrasive cut-off wheel
resulting in possible injury to persons in the vicinity.
• After operation, always switch off the tool and wait
until the wheel has come to a complete stop
before putting the tool down.
• When cutting concrete blocks, tiles or masonry
materials, do not make a cut in depth more than
60 mm. When you need to cut a workpiece over
60 mm up to 100 mm, make more than two
passes of cuts. The depth of the most efficient cut
is about 40 mm.
Hold the tool firmly with both hands. First keep the
wheel without making any contact with a workpiece to
be cut. Then turn the tool on and wait until the wheel
attains full speed.
Fig.6
The cut is made by pulling the tool toward you (not by
pushing away from you). Align the notch on the base
with your cutting line when performing a cut.
Switch off the tool in the position posed when finishing a
cut. Raise the tool after the wheel comes to a complete
stop.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
• Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may
result.
Dressing diamond wheel
If the cutting action of the diamond wheel begins to
diminish, use an old discarded coarse grit bench grinder
wheel or concrete block to dress the diamond wheel. To
do this, tightly secure the bench grinder wheel or
concrete block and cut in it.
Replacing carbon brushes
Fig.7
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced. Keep the carbon brushes
clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
Pick up an end of the dust cover slightly with hands so
that brush holder cap appears.
Use a screwdriver to remove the brush holder caps.
Take out the worn carbon brushes, insert the new ones
and secure the brush holder caps.
