Basic Saw Operations

Body and Hand Position

Position your body and hands prop- erly to make cutting easier and

safer. Observe the following instructions (Figure 1).

Correct	Incorrect Use

Figure 1. Hand Positions

•Never place hands near cutting area. Keep hands and arms outside the “No Hands” zone.

•The “No Hands Zone” is defined as the entire Table plus the fixed portion of the Base on the right and left side of the Table and portions of the Fence with- in this boundary. This zone is labeled by “No Hands” symbols placed on the fixed Base.

•Be aware of the path of the sawblade. Make a dry run with the saw OFF by conducting a simulated cutting cycle, and observe the projected path of the sawblade. Keep hands out of the path of sawblade.

DRY RUN—It is important to know where the blade will intersect with the workpiece during cutting oper- ations. Always perform the simulated cutting sequence with the power tool switched OFF to gain an understanding of the projected path of the saw- blade. Mentally note where the path of sawblade will fall and set up your work to keep your hands and arms out of the path of the spinning blade. Adjust your clamps and fences so that the smooth lower guard and cutting action is not interfered with during cutting operation.

•Hold workpiece firmly against table and fence to prevent movement.

•Keep hands in position until trigger has been released and blade has stopped completely.

•Keep feet firmly on the floor and maintain proper balance.

•Follow the miter arm when mitering left or right. Stand slightly to the side of the saw blade.

The lower guard may not automati- cally open under certain cutting conditions. For example, when trying to cut work-

pieces that are near the maximum cutting height capacity. Under these conditions, the workpiece can stop the lower guard movement before the downward motion of the arm could pre-open the lower guard.

If this occurs:

•Workpiece must be securely clamped. This frees a hand to raise the guard by the lip just enough to clear the workpiece (Figure 2).

•Start the saw and begin your cut.

•Once you have cleared the position where the lower guard may bind, release the guard and it will con- tinue to operate automatically as you cut.
