3. Loosen the handle release lever by lifting

it up and away from the Tilt-Lok™ handle

(Fig. 9).

WARNING

OPERATION

Fig. 9

4.To adjust the handle position, hold the front handle and rotate the Tilt-Lok™ handle to the desired angle as indicated by the handle rotation adjustment mark- ings (Fig. 10). The Tilt-Lok™ feature has eight (8) detents which allow the handle to snap into position. Allow the detent to snap into place.

If the Tilt-Lok™ handle moves with the handle release lever in the locked position, do not operate saw. Return the circular saw to a MILWAUKEE service facility for repair immedi- ately.

Adjusting the Blade to Shoe

The shoe has been adjusted at the factory to a 90 degree setting. Inspect the saw regu- larly to make sure the blade is 90 degrees to the shoe.

1.Unplug tool.

2.Set the bevel pointer to zero (Fig. 11).

WARNING

To reduce the risk of injury, wear safety goggles or glasses with side shields. Unplug the tool before changing accessories or making adjustments.

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 reac- tion drives the unit rapidly back toward the operator.

If the blade becomes twisted or mis- aligned 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.

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 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.

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 KICK- BACK.

NOTE: The blade depth setting will de- termine the range of Tilt-Lok™ positions available for the application. See “Adjust- ing Depth” for instructions on adjusting the blade depth.

5.Push the handle release lever back into the handle until it snaps into place.

WARNING

Do not operate saw with handle lever release button pressed in or with handle not locked into position.

NOTE: The saw will not operate if the handle release lever is not properly se- cured.

3.To make sure the blade is 90 degrees to the shoe, place saw on the blade side and retract lower guard. Place a square against the blade and shoe to inspect the degree setting (Fig. 12).

Bevel adjustment screw

4.To adjust the degree setting, loosen the bevel adjusting lever up by lifting it up towards the blade. Turn the bevel adjust- ment screw in or out until the blade is at a 90 degree angle with the shoe.

5.Check that the bevel pointer is at 0 de- grees. To adjust the bevel pointer, loosen the two screws in the front handle and re- position the bevel pointer to 0 degrees.

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:

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 at- tempt 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.

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 KICKBACK. 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 rip- ping. 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.
