3. When the battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys, nails,
screws or other small metal objects that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or a fire.
4. Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally occurs,
flush with water. If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may cause
irritation or burns.
SERVICE
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.
SPECIFIC SAFETY RULES
WARNING
1. Know your circular saw. DO NOT plug the charger into
the power source or install the battery in the tool until you
have read and understand this Instruction Manual. Learn
the tool’s applications and limitations, as well as the
specific potential hazards related to this tool. Following
this rule will reduce the risk of electric shock, fire, or
serious injury.
2.
Always wear eye protection. Any power tool can throw
foreign objects into your eyes and cause permanent eye
damage. ALWAYS wear safety goggles (not glasses)
that comply with ANSI safety standard Z87.1. Everyday
glasses have only impact resistant lenses. They ARE NOT
safety glasses.
3. Glasses or goggles not in compliance with ANSI Z87.1
could cause serious injury when they break.
4. Always keep hands out of the path of the saw blade.
Avoid awkward hand positions where a sudden slip could
cause your hand to move into the path of the saw blade.
5. Keep hands away from the cutting area and the blade.
Keep your second hand on the tool. If both hands are
holding the saw, they cannot be cut by the blade.
6. DO NOT reach underneath the workpiece. The guard
cannot protect you from the blade below the workpiece.
7. Adjust the cutting depth according to the thickness of
the workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece or approximately
3/8” (10 mm).
8. Never hold the piece being cut in your hands or across
your leg. Secure the workpiece on a stable platform. It is
important to support the workpiece properly to minimize
body exposure, blade binding, or loss of control.
9. Hold the 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.
10. When ripping, always use a straight edge guide. This
improves the accuracy of the cut and reduces the chance
of the blade binding.
11. 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.
12. Never use damaged or incorrect blade washers or bolt. The
blade washers and bolts were specially designed for your
saw, for optimum performance and safety of operation.
CAUSES AND OPERATOR PREVENTION
OF KICKBACK
1. 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;
2. 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.
3. 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.
4. 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 the left or right 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.
5. 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.
6. When restarting a saw in the workpiece, center the
saw blade in the kerf and check that saw teeth are not
engaged into the material. If the saw blades are binding,
it may walk up or kickback from the workpiece as the
saw is restarted.
7. 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.
8. DO NOT use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
9. 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.
10. Check the lower guard for proper closing before each
use. DO NOT operate the saw if the lower guard does
not move freely and close instantly. Never clamp or tie
the lower guard into the open position. If the saw is
accidentally dropped, the lower guard may be damaged.
Raise the lower guard with the retracting handle and
