Safety Rules for Mini Saw Attachment

DANGER

Keep your second hand on motor housing. If

both hands are holding the tool,they cannot be cut by the blade.Hold the tool firmly to prevent loss of

control. Figures in this manual illustrate typical hand support of the tool. NEVER place your hand behind the saw blade since kickback could cause the saw to jump backwards over your hand.

If your application does not allow two-hand control of the tool,keep your hand,fingers and body positioned to either side of the saw blade, but not in line with the saw blade. KICKBACK

could cause the saw to jump backwards. (See “Causes and Operator Prevention of Kickback.”)

Advance the blade only in a direction where the blade teeth are coming up through the workpiece. “Climb cutting” or feeding the

blade into the material so that the teeth are descending into the material, will cause the blade to climb out of the material and to

Keep hands away from cutting area and blade.

jump uncontrollably in the direction of this improper feed.

Be extremely careful when cutting round rods or when approaching corners or the edge of the workpiece.The blade can bind on the edge of

the workpiece and cause kickback.

Do not cut along a radius or curved line of cut.

Kickback will occur if a curved cutting motion is attempted.

Do not reach underneath the work. The guard cannot protect you from the blade below the work.

Check lower guard for proper closing before each use. Never clamp or tie the lower guard into the open position. If saw is accidentally

dropped,lower guard may be bent.Make sure the guard moves freely and does not touch the blade or any other part.

Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use.

Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a buildup of debris. Disconnect the plug from power source.

Periodically remove the blade, clean the lower guard and the hub area, or blow it clean with compressed air.

Always observe that the lower guard is covering the blade before placing the tool down on bench or floor. An unprotected,

coasting blade will cause the saw to cut whatever is in its path. Be aware of the time it takes for the blade to stop after switch is turned off.

NEVER hold piece being cut in your hands or across your leg. It is important to support the

work properly to minimize body exposure, blade binding, or loss of control.

Always use blades with correct size and shape arbor holes. Blades that do not match the

mounting hardware of the saw will run eccentrically,causing loss of control.

Do not run the tool while carrying it at your side. Lower guard may be opened by a contact with your clothing. Accidental contact with the spinning

saw blade could result in serious personal injury.

Know how to turn slide switch “OFF” in an emergency. If switch cannot turn “OFF” the tool

quickly,unplug the tool immediately.

CAUSES AND OPERATOR PREVENTION OF KICKBACK:

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.

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.

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.

Kickback is the result of tool 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 tool and position your body and arm to allow you to resist KICKBACK forces. KICKBACK forces can be

controlled by the operator, if proper precautions are taken.

When blade is binding, or when interrupting a cut for any reason,turn off the tool and hold the tool motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the tool backward while the blade is in motion or

KICKBACK may occur. Investigate and take

corrective action to eliminate the cause of blade binding. Wet lumber, green lumber or pressure-

treated lumber and most plastics require special attention during cutting operation to prevent KICKBACK. Avoid cutting nails. Inspect for and remove all nails from lumber before cutting.

When restarting a saw in a workpiece, center the saw blade in the kerf and check that saw teeth are not engaged into the material. If saw

blade is binding,it may walk up or KICKBACK from the workpiece as the tool is restarted.

Support 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.

Do not use dull or damaged blade.Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and KICKBACK.

Use extra caution when making a “Pocket Cut” into existing walls or other blind areas.

The protruding blade may cut objects that can cause KICKBACK.
