GENERAL SAFETY RULES

WARNING! Read all instructions. Failure to follow all

instructions listed below may result in electric shock, fire
and/or serious injury. The term "power tool" in all of the
warnings listed below refers to your mains-operated
(corded) power tool or battery-operated (cordless) power
tool.

SAVE THESE INSTRUCTIONS.

Work area safety

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

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

at 0° 75.5 mm (3")
at 45° 57 mm (2-1/4")
at 50° 51.5 mm (2")

GEA001-3

extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.

Personal Safety

9. 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.

10. Use safety equipment. Always wear eye
protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will
reduce personal injuries.

11. Avoid accidental starting. Ensure the switch is
in the off-position before plugging in. Carrying
power tools with your finger on the switch or
plugging in power tools that have the switch on
invites accidents.

12. 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.

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

14. 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.

15. If devices are provided for the connection of

dust extraction and collection facilities,
ensure these are connected and properly used.

Use of these devices can reduce dust-related
hazards.

Power tool use and care

16. Do not force the power tool. Use the correct

2

power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.

17. 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.

18. 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.

19. 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.

20. Maintain power tools. Check for misalignment

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

are caused by poorly maintained power tools.

21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.

22. Use the power tool, accessories and tool bits

etc. in accordance with these instructions and
in the manner intended for the particular type
of power tool, 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

23. 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.

24. Follow instruction for lubricating and

changing accessories.

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

GEB013-1

SPECIFIC SAFETY RULES

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

1. Keep hands away from cutting area and the
blade. Keep your second hand on auxiliary

handle, or motor housing. If both hands are

holding the saw, they cannot be cut by the blade.

2. Do not reach underneath the workpiece. The

guard cannot protect you from the blade below the
workpiece. Do not attempt to remove cut material
when blade is moving.
CAUTION: Blades coast after turn off. Wait until
blade stops before grasping cut material.

3. Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the blade
teeth should be visible below the workpiece.

4. Never hold piece being cut in your hands or

across your leg. Secure the workpiece to
stable platform. It is important to support the

work properly to minimize body exposure, blade
binding, or loss of control.

A typical illustration of proper hand support, workpiece
support, and supply cord routing (if applicable).

000157

5. Hold power 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 also

make exposed metal parts of the power tool "live"
and shock the operator.

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

7. Always use blades with correct size and shape
(diamond versus round) of arbour holes.
Blades that do not match the mounting hardware
of the saw will run eccentrically, causing loss of
control.

8. Never use damaged or incorrect blade
washers or bolt. The blade washers and bolt
were specially designed for your saw, for optimum
performance and safety of operation.

9. Causes and Operator Prevention of Kickback:

− kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the
workpiece toward the operator;

− when the blade is pinched or bound tightly by

3

the kerf closing down, the blade stalls and the
motor reaction drives the unit rapidly back
toward the operator;

− if the blade becomes twisted or misaligned in
the cut, the teeth at the back edge of the
blade can dig into the top surface of the wood
causing the blade to climb out of the kerf and
jump back toward the operator.

Kickback is the result of saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.

• Maintain a firm grip with both hands on the

saw and position your arms to resist
kickback forces. Position your body to
either side of the blade, but not in line with
the blade. Kickback could cause the saw to

jump backwards, but kickback forces can be
controlled by the operator, if proper
precautions are taken.

• When blade is binding, or when

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

corrective actions to eliminate the cause of
blade binding.

• When restarting a saw in the workpiece,

centre the saw blade in the kerf and check
that saw teeth are not engaged into the
material. If saw blade is binding, it may walk

up or kickback from the workpiece as the saw
is restarted.

• Support large panels to minimise the risk

of blade 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
saw on the workpiece, the saw should be rested on
the larger portion and the smaller piece cut off.

To avoid kickback, do support

board or panel near the cut.

000154

Do not support board or

panel away from the cut.

000156

• Do not use dull or damaged blades.

Unsharpened or improperly set blades
produce narrow kerf causing excessive friction,
blade binding and kickback. Keep blade sharp
and clean. Gum and wood pitch hardened on
blades slows saw and increases potential for
kickback. Keep blade clean by first removing it
from tool, then cleaning it with gum and pitch
remover, hot water or kerosene. Never use
gasoline.

• Blade depth and bevel adjusting locking

levers must be tight and secure before
making cut. If blade adjustment shifts while

cutting, it may cause binding and kickback.

• Use extra caution when making a "plunge

cut" into existing walls or other blind areas.
The protruding blade may cut objects that can
cause kickback. For plunge cuts, retract lower
guard using retracting handle.

• ALWAYS hold the tool firmly with both

hands. NEVER place your hand or fingers
behind the saw. If kickback occurs, the saw

could easily jump backwards over your hand,
leading to serious personal injury.

4

000194

• Never force the saw. Forcing the saw can

cause uneven cuts, loss of accuracy, and

possible kickback. Push the saw forward at

a speed so that the blade cuts without slowing.

10. Check lower guard for proper closing before

each use. Do not operate the saw if lower
guard does not move freely and close instantly.
Never clamp or tie the lower guard into the
open position. If saw is accidentally dropped,

lower guard may be bent. Raise the lower guard
with the retracting handle and make sure it moves
freely and does not touch the blade or any other
part, in all angles and depths of cut.
To check lower guard, open lower guard by hand,
then release and watch guard closure. Also check
to see that retracting handle does not touch tool
housing. Leaving blade exposed is VERY
DANGEROUS and can lead to serious personal
injury.

11. Check the operation of the lower guard spring.

If the guard and the spring are not operating
properly, they must be serviced before use.

Lower guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.

12. Lower guard should be retracted manually

only for special cuts such as "plunge cuts"
and "compound cuts." Raise lower guard by
retracting handle and as soon as blade enters
the material, the lower guard must be released.

For all other sawing, the lower guard should
operate automatically.

13. Always observe that the lower guard is

covering the blade before placing saw down
on bench or floor. An unprotected, coasting

blade will cause the saw to walk backwards,
cutting whatever is in its path. Be aware of the
time it takes for the blade to stop after switch is
released. Before setting the tool down after
completing a cut, be sure that the lower guard has

closed and the blade has come to a complete
stop.

14. Use extra caution when cutting damp wood,

pressure treated lumber, or wood containing
knots. Adjust speed of cut to maintain smooth

advancement of tool without decrease in blade
speed.

15. Avoid Cutting Nails. Inspect for and remove all

nails from lumber before cutting.

16. Place the wider portion of the saw base on that
part of the workpiece which is solidly
supported, not on the section that will fall off
when the cut is made. As examples, Fig. 1
illustrates the RIGHT way to cut off the end of
a board, and Fig. 2 the WRONG way. If the
workpiece is short or small, clamp it down. DO
NOT TRY TO HOLD SHORT PIECES BY HAND!

Fig. 1

000147

Fig. 2

000150

17. Never attempt to saw with the circular saw

held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.

5

000029

18. Some material contains chemicals which may

be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material
supplier safety data.

19. Do not stop the blades by lateral pressure on
the saw blade.

20. Always use blades recommended in this
manual. Do not use any abrasive wheels.

21. Wear a dust mask and hearing protection
when use the tool.

001460

Hold the tool firmly. The tool is provided with both a front
grip and rear handle. Use both to best grasp the tool. If
both hands are holding saw, they cannot be cut by the
blade. Set the base on the workpiece to be cut without
the blade making any contact. Then turn the tool on and
wait until the blade attains full speed. Now simply move
the tool forward over the workpiece surface, keeping it
flat and advancing smoothly until the sawing is
completed.
To get clean cuts, keep your sawing line straight and
your speed of advance uniform. If the cut fails to properly
follow your intended cut line, do not attempt to turn or
force the tool back to the cut line. Doing so may bind the
blade and lead to dangerous kickback and possible
serious injury. Release switch, wait for blade to stop and
then withdraw tool. Realign tool on new cut line, and
start cut again. Attempt to avoid positioning which
exposes operator to chips and wood dust being ejected
from saw. Use eye protection to help avoid injury.
