SAFETY RULES FOR SAW cont.
11. When removing the blades from the tool, ALWAYS wear protective gloves when
grasping the blades or accessory. Accessories may be hot after prolonged use°
KICKBACK..WHAT CAUSES IT AND WAYS TO PREVENT IT
The Causes of Kickback
t. Kickback isa sudden reaction to a pinched, bound or misaIfgnedsaw blades,
which cause the uncontroIfedsaw to lift up and outof the workpiece and towards
the operator.
2, When the blades are pinched or bound tightly bythe kerr closing down, the blades
stall and the motor reaction drives the unit rapidly backtowards the operator.
3. if the blades become twisted or misaligned in the cut, the teeth at the back edges
of the blades can dig intothe top surface of the wood°This causes the blades to
climb out of the kerf and jump back towards the operator.
4. Kickback isa result of toolmisuse and!or incorrectoperating procedures or
conditions,it can be avoided by taking the proper precautions, as listed below°
Ways to Prevent Kickback
1. ALWAYS maintain a firm grip with both hands on the saw and position your
body and arms to allow you to resist KICKBACK forces, KICKBACK forces can
be controlled by the operator, ifthe proper precautions are taken.
2. If the blades are binding, or when you are interrupting a cut for any reason,
ALWAYS turn off the saw and hold the saw motionless in the material until
the blades come to a complete stop. NEVER attempt to remove the saw from
the work or pull the saw backward while the blades are in motion or
KICKBACK may occur. ALWAYS check and be ready to take corrective action to
eliminate the cause of blade binding_
3. When restarting the saw in the workpiece, ALWAYS center the blades in the
kerr and check to be sure that the saw teeth are not engaged into the
material. If the saw blades are binding, they may walk up or KICKBACK from the
workpiece when the saw is restarted
4. ALWAYS support large panels to minimize the risk of blades pinching and
KICKBACK. Large panels tend to sag under theirown weight. Supports MUST be
placed under the panel on both sides, near the line ofcut and near the edge of the
panel.
5, DO NOT use a dull or damaged blades, Unsharpened or Improperly set blades
produce narrow kerf which causes excessive friction, blade binding and
KICKBACK
6, ALWAYS use extra caution when making a "Pocket Cut" into existing walls or
other blind areas. The protruding blades may cut objects that can cause
KICKBACK.
7. ALWAYS have the saw blades at full speed before contacting workpiece
8. ALWAYS keep your body positioned toeither side of the saw btades, but not in line
with the saw blades_KICKBACK could cause the saw tojump backwards towards
the operator, KICKBACK forces can be controlledbythe operator, If proper
precautions are taken,
ALWAYS hold tool by insulated gripping surfaces when performing an
operation where the cuffing tool 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. 6
