SAFETY RULESFORCIRCULAR SAWS cont.
7. NEVER hold the piece being cut in your hands or across your legs,
it is important to support the work properly in order to minimize body
exposure, blade binding, or loss of control
8. ALWAYS hold tool by insulated gripping surfaces when performing
an operation where the cutting toot may contact hidden wiring or its
own cord. Contact with a 'live" wire will make the exposed metal parts of
the tool "live" and shock the operator
9. When ripping, ALWAYS use a rip fence or straight edge guide.
This improves the accuracy of the cut and reduces the chance of
the blade binding
10, ALWAYS use blades that have the correct size and shape
(diamond vs. round) arbor holes. Blades that do not match
the mounting hardware of the saw will run erratically and
will cause loss of control.
11. ALWAYS BE SURE that all adjusting screws and the blade holder
are fastened tightly BEFORE making a cut, Loose adjusting screws
and holders can cause the tool or blade to slip and loss
of control may result°
12. When removing the blade from the tool, ALWAYS avoid contact
with skin and ALWAYS wear protective gloves when grasping
the blade or accessory. Accessories may be hot after
prolonged use.
KICKBACK...WHAT CAUSES IT AND WAYS TO PREVENT IT
The Causes of Kickback
1. Kickback is a sudden reaction to a pinched, bound or misaligned
saw blade, which causes the uncontrolled saw to lift up and out
of the workpiece and towards 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
towards 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. This causes the blade to climb out of the kerr and
jump back towards the operator.
4. Kickback is a result of tool misuse and!or incorrect operating
procedures or conditions° It can be avoided by taking the proper
precautions, as listed on next page.
