Check the blades to ensure that they are not split, cracked or damaged in any way. If in doubt do not use the blade.
Saw blades must be securely attached before use, but not overtightened.
Secure unstable workpiece with a clamp, vice or other adequate holding device and ensure that the saw is gripped with both hands.
Keep children and unauthorised persons away from the work area.
DO NOT operate the saw if any parts are missing or damaged.
DO NOT use the saw for a task it is not designed to perform.
DO NOT operate the saw where there are flammable liquids or gases.
WARNING! DO NOT use on materials containing asbestos.
DO NOT get the saw wet or use in damp or wet locations.
DO NOT switch the saw on whilst the blade is in contact with the workpiece.
DO NOT cover the saw air vents. To do so will overheat the machine.
DO NOT touch the workpiece immediately after cutting as it will be very hot.
DO NOT hold unsecured work in your hand and DO NOT touch the saw blade whilst operating, or whilst plugged into the mains power.
DO NOT leave the saw running unattended and DO NOT lay it down whilst it is running.
DO NOT operate the saw when you are tired or under the influence of alcohol, drugs or intoxicating medication.
When not in use, switch off, remove plug from power supply and store in safe, dry, childproof area.

SPECIAL PRECAUTIONS
DANGER: Keep hands away from cutting area and the blade.
Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
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.
Never hold the workpiece 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.
Hold the power tool only by the 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.
When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade
binding.
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.
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.

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 back
rapidly 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 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.
Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade
binding and kickback.
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.
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.
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.
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.
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.
DO NOT work overhead with the saw. In this position you do not have sufficient control of the power tool.
Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance.
Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water
line causes property damage or may cause an electric shock.
