WARNING
To reduce the risk of injury, keep hands away from the blade and other moving parts. Always wear safety goggles or glasses with side shields. Use only specifically recommended accesso- ries. Others may be hazardous.
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, or cutting slot, 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 operator.
KICKBACK is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precau- tions as given below:
1.Maintain a firm grip with both hands on the saw and position your body and arm to allow you to resist KICK- BACK forces. KICKBACK forces can be controlled by the operator, if proper precautions are taken.
2.When blade is binding, or when inter- rupting a cut for any reason, release the trigger and hold the saw motion- less 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 cor- rective actions to eliminate the cause of blade binding.
3.When restarting a saw in the work- piece, center the saw blade in the kerf, or cut, 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 saw is restarted.
4.Support large panels to minimize the risk of blade pinching and KICK- BACK. 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 dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and KICKBACK.
6.Blade depth and bevel adjusting lock- ing levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and KICKBACK.
7.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.
8.Set the depth of cut for no more than 1/8" to 1/4" greater than the thickness of the stock. The less blade exposed, the less chance of binding and KICK- BACK. Before cutting, be sure depth and bevel adjustments are tight.
9.Be cautious of pitchy, knotty, wet or warped stock. These are most likely to create pinching conditions and possible KICKBACK. Do not rip warped lumber. Avoid cutting nails.
10.Use a rip fence or edge guide when ripping. Guides improve control and reduce blade binding.
11.Stay alert. Any distraction can cause twisting or binding. Repetitive cuts may lull the user into careless movements.
Always clamp the workpiece securely on a saw horse or bench (Fig. 10). See “APPLICA- TIONS” for the correct way to support your work in different situations.

1.Draw a cutting line. Place the front of the shoe on the edge of the workpiece without making blade contact. Hold the handle with one hand and the front handle with the other (Fig. 12).

2.Line up the sight line with your cutting line. Position your arms and body to resist KICKBACK.
3.To start the saw, push the
grip. Do not force the saw through the |
workpiece. Forcing a saw can cause |
KICKBACK. |
5. If making a partial cut, restarting in |
the blade to come to a complete stop. |
To resume cutting, center the blade in |
the kerf, back the saw away from cutting |
edge a few inches, push the |
button down while pulling the trigger and |
6. If the saw binds and stalls, maintain |
a firm grip and release the trigger im- |
mediately. Hold the saw motionless in |
the workpiece until the blade comes to |
a complete stop. |
7. After finishing a cut, be sure the lower |
guard closes and the blade comes to a |
complete stop before setting the saw |
down. |
Electric Brake
The electric brake engages when the trig- ger is released, causing the blade to stop and allowing you to proceed with your work. Generally, the saw blade stops within two seconds. However, there may be a delay between the time you release the trigger and when the brake engages. Occasionally the brake may miss completely. If the brake misses frequently, the saw needs servicing by an authorized MILWAUKEE service facil- ity. The brake is not a substitute for the guard, and you must always wait for the blade to stop completely before removing the saw from the workpiece.
