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.

The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.

Work area safety

1. Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

2. Do not operate power tools in explosive

atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools

create sparks which may ignite the dust or fumes.

3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.

Electrical Safety

4. 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. Unmodified plugs and matching outlets will

reduce risk of electric shock.

5. 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.

6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.

7. 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.

8. 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.

9. If operating a power tool in a damp location is

unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of an

GFCI reduces the risk of electric shock.

Personal Safety

10. 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 influence of drugs, alcohol or
medication. A moment of inattention while

operating power tools may result in serious
personal injury.

11. 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.

12. Prevent unintentional starting. Ensure the

switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. . Carrying power tools

with your finger on the switch or energising power
tools that have the switch on invites accidents.

13. 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.

3

14. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.

15. Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes,

jewellery or long hair can be caught in moving
parts.

16.

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 dust-related hazards.

Power tool use and care

17. 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.

18. Do not use the power tool if the switch does
not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.

19. Disconnect the plug from the power source

and/or the 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.

20. 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.

21. Maintain power tools. Check for misalignment

or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents

are caused by poorly maintained power tools.

22. Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.

23. 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 different from those intended
could result in a hazardous situation.

Service

24. Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power

tool is maintained.

25. Follow instruction for lubricating and

changing accessories.

26. Keep handles dry, clean and free from oil and
grease.

USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size to
use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gage. The smaller
the gage number, the heavier the cord.

SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to cutter safety rules. If you use this tool unsafely or
incorrectly, you can suffer serious personal injury.

1.

DANGER! Keep hands away from cutting area
and wheel. Keep your second hand on auxiliary
handle or motor housing.

If both hands are

holding the tool, they cannot be cut by the wheel.

4

2.

Keep your body positioned to either side of the
wheel, but not in line with the wheel.

KICKBACK
could cause the tool to jump backwards. (See
"Causes and Operator Prevention of Kickback")

3. Do not reach underneath the work. Do not

attempt to remove cut material when wheel is
moving.
CAUTION: Wheels coast after turn off.

4. Always observe that the wheel has stopped

spinning before placing tool down on bench
or floor. A coasting wheel will cause the tool to

walk backwards, cutting whatever is in its path. Be
aware of the time it takes for the wheel to stop after
switch is released.

5. NEVER hold piece being cut in your hands or
across your leg. It is important to support the
work properly to minimize body exposure, wheel
binding, or loss of control.

6. Hold tool by insulated gripping surfaces when

performing an operation where the cutting tool
may contact hidden wiring or its own cord.

Contact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.

7. When ripping always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance for wheel binding.

8.

Always use wheels with correct size and shape
(diamond vs. round) arbor holes.

Wheels that do
not match the mounting hardware of the tool will
run eccentrically, causing loss of control.

9. Never use damaged or incorrect wheel
washers or bolts. The wheel washers and bolt
were specially designed for your tool, for optimum
performance and safety of operation.

10. Causes and Operator Prevention of Kickback:
Kickback is a sudden reaction to a pinched, bound,
or misaligned wheel, causing an uncontrolled tool
to lift up and out of the workpiece toward the
operator.
When the wheel is pinched or bound tightly by the
kerf closing down, the wheel stalls and the motor
reaction drives the unit rapidly back toward the
operator.
If the wheel becomes twisted or misaligned in the
cut, the teeth at the back edge of the wheel can dig
into the top surface of the material being cut
causing the wheel to climb out of the kerf and jump
back toward the operator.
Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:

Maintain a firm grip on the tool and position
your body and arm to allow you to resist
KICKBACK forces. KICKBACK forces can be

controlled by the operator, if proper precautions are
taken.

When wheel is binding, or when interrupting a
cut for any reason, release the trigger and hold
the tool motionless in the material until the
wheel comes to a complete stop. Never attempt
to remove the tool from the work or pull the
tool backward while the wheel is in motion or
KICKBACK may occur. Investigate and take

corrective actions to eliminate the cause of wheel
binding.

When restarting a tool in the workpiece, center
the wheel in the kerf and check that teeth are
not engaged into the material. If wheel is binding,

it may walk up or KICKBACK from the workpiece as
the tool is restarted.

Support large panels to minimize the risk of
wheel pinching and KICKBACK. Large panels

tend to sag under their own weight. Supports must
be placed under the panel on both sides, near the
line of cut and near the edge of the panel.
To minimize the risk of blade pinching and kickback.
When cutting operation requires the resting of the
tool on the workpiece, the tool should be rested on
the larger portion and the smaller piece cut off.
Do not use dull or damaged wheel.
Unsharpened or improperly set wheels produce
narrow kerf causing excessive friction, wheel
binding and KICKBACK.

Wheel depth and bevel adjusting locking levers
must be tight and secure before making cut. If

wheel adjustment shifts while cutting, it may cause
binding and KICKBACK.

Use extra caution when making a "Pocket Cut"
into existing walls or other blind areas. The

protruding wheel may cut objects that can cause
KICKBACK.

NEVER place your hand or fingers behind the
tool. If kickback occurs, the tool could easily jump

backwards over your hand, leading to serious
personal injury.

11. When operating the tool, keep the cord away

from the cutting area and position it so that it
will not be caught on the workpiece during the
cutting operation. Operate with proper hand
support, proper workpiece support, and
supply cord routing away from the work area.
WARNING: It is important to support the
workpiece properly and to hold the tool firmly
to prevent loss of control which could cause
personal injury.

12. Use only diamond wheels. NEVER use tool
with wood cutting blades or other sawblades.
Such blades when used on this tool frequently
kick and cause loss of control leading to

5

personal injury.

13. Check the wheel carefully for cracks or
damage before operation. Replace cracked or
damaged wheel immediately.

14. Use only flanges specified for this tool.

15. Be careful not to damage the spindle, flanges

(especially the installing surface) or bolt.
Damage to these parts could result in wheel
breakage.

16. Make sure the wheel is not contacting the
workpiece before the switch is turned on. Wait
until the wheel attains full speed before
cutting.

17. Stop operation immediately if you notice
anything abnormal.

18. Never attempt to cut with the tool held upside
down in a vise. This can lead to serious
accidents, because it is extremely dangerous.

19. Do not stop the wheel by lateral pressure on
the disc.

20. Some material contains chemicals which may
be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material
supplier safety data.

21. The tool must be used only for dry cutting. DO
NOT use water.

SAVE THESE INSTRUCTIONS.

Consignes de sécurité générales
pour outils électriques

MISE EN GARDE Veuillez lire toutes les mises en

garde de sécurité et toutes les instructions.

L'ignorance des mises en garde et des instructions
comporte un risque de choc électrique, d'incendie et/ou
de blessure grave.

Conservez toutes les mises en
garde et instructions pour
référence future.

Le terme ≪ outil électrique ≫ qui figure dans les
avertissements fait référence à un outil électrique
branché sur une prise de courant (par un cordon
d'alimentation) ou alimenté par batterie (sans fil).

Sécurité de la zone de travail

1. Maintenez la zone de travail propre et bien
éclairée. Les zones de travail encombrées ou

sombres ouvrent grande la porte aux accidents.

2. N'utilisez pas les outils électriques dans les

atmosphères explosives, par exemple en
présence de liquides, gaz ou poussières
inflammables. Les outils électriques produisent

des étincelles au contact desquelles la poussière
ou les vapeurs peuvent s'enflammer.

3. Assurez-vous qu'aucun enfant ou curieux ne

s'approche pendant que vous utilisez un outil
électrique. Vous risquez de perdre la maîtrise de

l'outil si votre attention est détournée.

Sécurité en matière d'électricité

4. Les fiches d'outil électrique sont conçues
pour s'adapter parfaitement aux prises de
courant. Ne modifiez jamais la fiche de

quelque façon que ce soit. N'utilisez aucun
adaptateur de fiche sur les outils électriques
avec mise à la terre. En ne modifiant pas les

fiches et en les insérant dans des prises de
courant pour lesquelles elles ont été conçues vous
réduirez les risques de choc électrique.

5. Évitez tout contact corporel avec les surfaces

mises à la terre, telles que les tuyaux,
radiateurs, cuisinières et réfrigérateurs. Le

risque de choc électrique est plus élevé si votre
corps se trouve mis à la terre.

6. N'exposez pas les outils électriques à la pluie
ou à l'eau. La présence d'eau dans un outil
électrique augmente le risque de choc électrique.

7.

Ne maltraitez pas le cordon. N'utilisez jamais le
cordon pour transporter, tirer ou débrancher
l'outil électrique. Maintenez le cordon à l'écart
des sources de chaleur, de l'huile, des objets à
bords tranchants et des pièces en mouvement.

Le risque de choc électrique est plus élevé lorsque
les cordons sont endommagés ou enchevêtrés.

8. Lorsque vous utilisez un outil électrique à

l'extérieur, utilisez un cordon prolongateur
prévu à cette fin. Les risques de choc électrique

sont moindres lorsqu'un cordon conçu pour
l'extérieur est utilisé.

9. Si vous devez utiliser un outil électrique dans

un endroit humide, utilisez une source
d'alimentation protégée par un disjoncteur de
fuite à la terre. L'utilisation d'un disjoncteur de

fuite à la terre réduit le risque de choc électrique.

Sécurité personnelle

10.

Restez alerte, attentif à vos mouvements et
faites preuve de bon sens lorsque vous utilisez
un outil électrique. Évitez d'utiliser un outil
électrique si vous êtes fatigué ou si vous avez
