14. Maintain a firm grip on the saw and position your body and arm in a

way that allows you to resist KICKBACK forces. KICKBACK forces can be

controlled by the operator, if proper precautions are taken.

15. When blade is binding, or when interrupting a cut for any reason,

release the trigger and hold the saw motionless in the material until the

blade comes to a complete stop. Never attempt to remove the saw from

the work or pull the saw backward while the blade is in motion or

KICKBACK may occur. Investigate and take corrective actions to eliminate

the cause of blade binding.

16. When restarting a saw in the workpiece, center the saw blade in the

kerf and check that teeth are not engaged into the material. If saw blade

is binding, it may walk up or KICKBACK from the workpiece as the saw is

restarted.

17. Support large 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.

18. Do not use dull or damaged blade. Unsharpened or improperly set

blades produce narrow kerf causing excessive friction, blade binding, and

KICKBACK.

19. Blade depth and bevel adjusting locking levers must be tight and

secure before making cut. If blade adjustment shifts while cutting, it will

cause binding and KICKBACK.

20. 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.

21. Some wood contains preservatives which can be toxic. Take extra

care to prevent inhalation and skin contact when working with these

materials. Request, and follow, all safety information available from your

material supplier.
