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.
at 90° 60 mm (2-3/8") at 45° 44 mm (1-3/4") at 50° 40 mm (1-9/16")
GEA007-1
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.
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.
14. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

A
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
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. Use only three­wire extension cords that have three-prong grounding-type plugs and three-pole receptacles that accept the tool’s plug. Make sure your extension cord is in good condition. Replace or repair damaged or worn cord immediately. 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.

CIRCULAR SAW SAFETY WARNINGS
Cutting procedures
1.
DANGER: 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.
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 a 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 and workpiece support.
000161
5.
Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting tool may contact hidden wiring or its own cord.
make exposed metal parts of the power tool "live" and could give the operator an electric shock.
Contact with a "live" wire will also
6. When ripping, always use a rip fence or straight edge guide. This improves the accuracy of 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.
Kickback causes and related warnings
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 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.
9. 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.
10. 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.
11. 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.
12. 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 avoid kickback, do support
board or panel near the cut.
000192
Do not support board or panel away from the cut.
014252
13. Do not use dull or damaged blades.
Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.
14. 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.
15. Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.
16. 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.
000160
17. Never force the saw. Push the saw forward at
a speed so that the blade cuts without slowing. Forcing the saw can cause uneven cuts,
loss of accuracy, and possible kickback.
Lower guard function
18. 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.
19. 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.
20. 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.
21. 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.
22. 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.

Additional safety warnings
23. Intended use This tool is intended to cut wood products only. Accumulated sawdust on the lower guard
and hub from other materials may effect the proper closure of the lower guard which could lead to serious personal injury.
24. Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing knots. Maintain smooth advancement of tool
without decrease in blade speed to avoid overheating the blade tips.
25. Do not attempt to remove cut material when
blade is moving. Wait until blade stops before grasping cut material.Blades coast after turn off.
26. Avoid Cutting Nails. Inspect for and remove all nails from lumber before cutting.
27. 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
014997
Fig. 2
000190
28. 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.
29. Never attempt to saw with the circular saw held upside down in a vise. This is extremely dangerous and can lead to serious accidents.
000029
30. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
31. Do not stop the blades by lateral pressure on the saw blade.
32. Do not use any abrasive wheels.
33. Only use the blade with the diameter that is marked on the tool or specified in the manual. Use of an incorrectly sized blade may affect the proper guarding of the blade or guard operation which could result in serious personal injury.
34. 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.
35. Wear a dust mask and hearing protection
when use the tool.

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.
Rip fence (Guide rule) - optional accessory
1. Rip fence (Guide rule)

007402
The handy rip fence allows you to do extra-accurate straight cuts. Simply slide the rip fence up snugly against the side of the workpiece and secure it in position with the screw on the front of the base. It also makes repeated cuts of uniform width possible.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or maintenance.
Clean out the upper and lower guards to
ensure there is no accumulated sawdust which may impede the operation of the lower guarding system. A dirty guarding system may
limit the proper operation which could result in serious personal injury. The most effective way to accomplish this cleaning is with compressed air.
If the dust is being blown out of the guards be sure the proper eye and breathing protection is used.
Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may result.
