SAFETY RULES FOR SAW cont.
11.When removing theblades from the tool, ALWAYS wearprotective gloves when
graspingthe bladesor accessory. Accessories may be hot after prolonged use°
KICKBACK..WHAT CAUSES ITAND WAYSTO PREVENT IT
The Causes of Kickback
t. Kickback is asudden reaction to apinched, bound or misaIfgned saw blades,
whichcause the uncontroIfedsaw to lift up and outof the workpiece and towards
the operator.
2, When the blades are pinched or bound tightly by the kerrclosing down, the blades
stall and the motor reaction drives the unit rapidly back towards the operator.
3. if the blades become twistedor misaligned in the cut, the teeth at the back edges
ofthe blades can dig intothe top surface of the wood°This causes the blades to
climbout ofthe kerf and jump back towards the operator.
4. Kickback is a result of tool misuse 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 afirm grip with both hands on the saw and position your
body and arms to allow you to resist KICKBACK forces, KICKBACK forces can
be controlledby 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 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.
5,DO NOT use adull or damaged blades, Unsharpened or Improperly set blades
producenarrow 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 cancause
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
withthe saw blades_KICKBACK could causethe saw tojump backwards towards
the operator, KICKBACK forces can be controlled by the 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.
Contactwith a "live" wire will make the exposed metal parts of the tool "live" and
shock the operator. 6
