GENERAL POWER TOOL SAFETY WARNINGS
WARNING Read all safety warnings and 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
1. 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.
2. 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.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
4. 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.
5. 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.
6. 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. NOTE: The term “residual current device (RCD)” may
be replaced by the term “ground fault circuit interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.
PERSONAL SAFETY
1. 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.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mark, non-
skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
3. Prevent unintentional starting. Ensure the switch us 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 energizing
power tools that have the switch on invites accidents.
4. 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.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in
unexpected situations.
6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair can be caught in moving parts.
7. 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
1. 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.
2. 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.
3. 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 preventative safety measures reduce the risk of
starting the power tool accidentally.
4. 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.
5. 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.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are les likely to
bind and are easier to control.
7. 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
1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will
ensure that they safety of the power tool is maintained.
SAFETY INSTRUCTIONS FOR ALL SAWS
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.
NOTE: For circular saws with 140 mm or smaller diameter blades, the “Keep your second hand on the auxiliary
handle, or motor housing” may be omitted.
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.
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 of cut and reduces the
chance of blade binding.
7. Always use blades with correct size and shape (diamond versus round) or 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.
FURTHER SAFETY INSTRUCTIONS FOR ALL SAWS
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 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:
1. 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. NOTE: for
circular saws with 140 mm or smaller diameter blades, the words “with both hands” may be omitted.
2. When the 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.
3. 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.
4. Support large panels to minimize 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.

5. Do not use dull or damaged blades. Unsharpened and improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
6. 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.
7. 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.
SAFETY INSTRUCTIONS FOR SAWS
1. 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. NOTE: Alternate
wording may be substituted for “retracting handle”.
2. 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
build-up of debris.
3. 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. NOTE: Alternate wording may be
substituted for “retracting handle”.
4. 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.

PREPARATION AND OPERATION
BLADE REMOVAL AND INSTALLATION
Fig. 2 Fig. 3 Fig. 4
1. Unplug the saw from its power source before performing any servicing or changing the blade.
2. Remove the chip collection unit (see Chip Collection and Removal Chamber section for removal instructions)
3. Depress the spindle lock to stop the blade/spindle rotation. (fig.2)
4. Use the supplied 6 mm hex key to remove the bolts/washers (2) and flange holding the blade. (fig. 3)
5. Rotate the blade guard away from the blade. Remove the used blade.
6. Replace with a sharp new blade.
7. Replace the flange,washers and bolt.
8. Depress the spindle lock and securely tighten the bolt.
Note: Make sure that the arrow on the blade and the teeth are rotating counterclockwise.
9. Release the spindle lock. Check to be sure that it has fully released by manually rotating the blade. (fig.4)
10. Replace and securely latch the chip collection unit.
MAKING A CUT
Whenever possible, always clamp the work piece to a rigid support.
1. Before starting the saw motor:
a. Place the front edge squarely on the work piece.
b. Ensure that the blade is not touching the material to be cut.
c. Sight the cutting line with the line of the cut guide.
2. Allow the saw to come to a full start before you begin to cut.
3. Introduce the blade slowly so as to not damage the teeth of the blade.
Note: Do not force the saw. Allow the speed of the saw blade to do the work.
4. Using both hands, move the saw forward through the work piece. Applying more pressure on the saw will not
improve the cutting performance, but will reduce the life of the blade.

ADJUSTING THE CUTTING DEPTH
WARNING! Before adjusting, make sure that that power to the saw is turned OFF.
1. Release the lock to adjust to the required cutting depth. (fig.5)
2. Make sure that the blade protrudes at the maximum cutting depth that the saw is capable of in the
material being cut.
3. Tighten to lock into position. Check to ensure that the lock will not loosen while being used.
Note: Metal cutting blades work best while having the maximum amount of blade engaged in the cutting
action. This distributes the cutting load among the teeth on the blade. This is the opposite of how a wood cutting
blade is used, where minimal blade protrusion allows the operator to make a cut while minimizing the potential
for the blade to become bound in the cut and produce material tearout.
Exception: Metal grating is best cut by having the blade protrude very minimally beyond the depth of the
grating. The interrupted cuts that occur when cutting grating are very hard on the blade and carbide tips.

PARALLEL BLADE GUIDE
1. Loosen the two retaining screws.
2. Slide the guide up snugly against the side of the work piece.
3. Using a measuring tape, check that the distances from the front and the back of the blade to the edge of the
blade guide are equal. This will ensure that the guide is parallel to the blade. The guide should be parallel to
the blade, and not to the base of the tool, to avoid damage to both blade and motor.
4. Retighten the screws.
TOOL OVERLOAD / RESET:
If the tool overload protection device activates, allow the motor to cool, and then press the reset button to continue
operation. (fig.6)
