SAFETY RULES FOR SAWS

•'_ DANGERf Keep hands away from cutting area and blades. Keep your I

second hand on the auxiliary handle or motor housing. Ifbothhandsare

I

holding the saw, theycannot be cutby the blades.

1. ALWAYS keep your body positioned to either side of the saw blades, but not

in line with the saw blades.

2. DO NOT reach underneath the work. The guardcannotprotectyoufromthe

bladesbeneath thework.

3. ALWAYScheck guard for proper closing BEFORE each use. DO NOT operate

the saw if the guard does not move freely and close instantly. Never clamp or

tie the blade guard In the open position. Ifthe saw isaccidentallydropped,the

guard may be bent.Raisethe guardand make surethat itmovesfreely and does

nottouchthebladesoranyotherpart.

4. ALWAYScheck the operation and condition of the guard spring. If the guard

and the spring are not operating properly,they MUST be serviced before use,

The blade guard may operatesluggishly,due todamaged parts, gummy deposits,

or a buildupofdebris.

5. The guard should be retracted manually ONLY for making special cuts, such

as pocket or compound cuts. ALWAYS raise the guard by retracting the

handle. As soon as the blade enters the material, the guard MUST be

released. Forall othersawing,theguard shouldoperateautomatically.

6. ALWAYS make sure that the guard Is covering the blades BEFORE placing the

KICKBACK..,WHAT CAUSES IT AND WAYSTO PREVENT IT

The Causes of Kickback

1. Kickbackis a sudden reaction to a pinched, bound or misaligned saw blades,

which cause the uncontrolled saw to lift up and out of the workpiece and towards

the operator.

2. When the blades are pinched or bound tightly by the kerr closing down, the blades

stall and the motor reaction drives the unit rapidly back towards the operator.

3. ifthe blades become twisted or misaligned in the cut, the teeth at the back edges

of the blades can dig into the top surfaceof the wood, This causes the blades to

climb out of the kerf and jump back towardsthe operator.

4. Kickback is a result of tool misuse and/orincorrect operating 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, KICKBACKforcescan

be controlledby the operator, if the proper precautions are taken,

2. Ifthe 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 checkand be readyto take corrective actionto

eliminate the cause of blade binding.

3.When restarting the saw In the workpiece, ALWAYS center the blades In the

kerf and check to be sure that the saw teeth are not engaged Into the

material. Ifthe saw blades are binding,they maywalk upor KICKBACKfromthe

workpiece when the saw isrestarted.

4. ALWAYS support large panels to minimize the risk of blades pinching and

KICKBACK. Large panelstendto sag undertheirown weight.SupportsMUST be

placed underthe panel on bothsides,near the line ofcut and near the edge ofthe

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 bladesmay outobjectsthat can cause

KICKBACK.

7. ALWAYS havethe saw blades at fullspeed beforecontactingworkpiece

8. ALWAYS keepyourbody positioned to eitherside ofthe saw blades, but not in line

with the saw blades. KICKBACKcouldcause the saw tojump backwards towards

the operator.KICKBACK forcescan be controlled bythe operator, ifproper

precautions are taken.

ALWAYS hold tool by insulated gripping surfaces when performing an

operation where the cutting tool may contact hidden wiring or its own cord.

Contactwith a "live" wirewillmake theexposedmetal parts of the tool"live" and

shock the operator. 6

FEED SPEED

F,0.

Feed speed ishow quickly you push the saw blades throughthe material being cut,

The correct feed speed is totally determined by the hardness and the thickness of

the material being cut,

IMPORTANT: FeedingmustALWAYS be done withthe bladesperpendicular tothe

planeof theworkpiece (See Fig.A). Feedingat an angle can burn the blade and

damage the bladeteeth (See Fig. B).

Selecting the correct feed speed Is important.

If the feed speed Is too slow:

1. The blades will onlypress downon the material rather than cuttingit,

2. The bladeedges glideand wear downthe material.

3. A poorcut willresultand cause excessivewear on the blades

If the feed speed Is too fast:

1. There isa definite riskthatthe cut mFghtsplitand the splinteredopeningofthecut
