additional safety rules for laser lights

The laser light/laser radiation used in this system is Class III, with maximum 5mW And
wavelengths of 635-665 nm. Under normal circumstances, these lasers do not present an
optical hazard, but staring at the beam may cause flash blindness.
WARNING!
Do not stare directly at the laser beam.
A hazard may exist if you deliberately stare into the beam. Please observe all of the
following safety rules:
• The laser must be used and maintained in accordance with the manufacturer's instructions.
• Never aim the beam at any person or any object other than the workpiece.
• Always ensure that the laser beam is aimed at a sturdy workpiece
that does not have reflective surfaces. wood and rough coated
surfaces are acceptable. Bright, shiny reflective sheet steel or
similar materials are not suitable for laser use, because the
reflective surface could direct the beam back at the operator.
• Do not replace the laser light assembly with a different type.
Repairs must be carried out by the laser manufacturer, or by an
authorized agent.
• ALwAYS turn the laser beam off when not in use. Leaving the tool
on increases the risk of someone inadvertently staring into the
laser's beam.
CAUTION!
Using controls or adjustments or performing procedures other than those specified herein
may result in hazardous radiation exposure.

Specific safety rules for circular saws

DanGer
• Keep hands away from cutting area and 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.
• Do not reach underneath the work piece. The guard cannot protect you from the blade below
the work piece.

• Adjust the cutting depth to the thickness of the work piece.. Less than a full tooth of the
blade teeth should be visible below the work piece.
• Never hold piece being cut in your hands or across your leg. Secure the work piece to
a stable platform. It is important to support the work properly to minimize body exposure, blade
binding, or loss of control.
• 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.
• 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 arbor 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 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 if the wood causing the blade to climb out the kerf and jump back toward the
operator.

• 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.
