To Install the Blade (Fig.3)

WARNING: Remove battery before service,adjustment, installing or removing accessories.

1. Place inner clamp washer on saw spindle.

2.Retract the lower blade guard ⑧ and place blade on saw spindle against the inner clamp washer, making sure that the blade will rotate in the proper direction(the direction of the rotation arrow on the saw blade and the teeth must point in the same direction as the direction of rotation arrow on the lower blade guard). Do not assume that the printing on the blade will always be facing you when properly installed. When retracting the lower blade guard to install the blade, check the condition and operation of the lower blade guard to assure that it is working properly. Make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.

3.Place outer clamp washer 16 on saw spindle with the large flat surface against the blade with beveled side facing out.

4.Thread blade clamping screw 9 into saw spindle by hand (screw has left-hand threads and must be turned counterclockwise to tighten).

5.Depress the blade lock button 12 while turning the saw spindle with the blade wrench 14 counterclockwise until the blade lock engages and the blade stops rotating.

6.Tighten the blade clamping screw firmly with the blade wrench.

NOTE: Never engage the blade lock while saw is running, or engage in an effort to stop the tool. Never turn the saw on while the blade lock is engaged. Serious damage to your saw will result.

⚠️ WARNING: Remove battery before service,adjustment, installing or removing accessories.

1.To loosen the blade clamping screw 9, depress the blade lock button 12 and turn the saw spindle with the blade wrench 14 until the blade lock engages and the blade stops rotating. With the blade lock engaged, turn the blade clamping screw clockwise with the blade wrench (screw has left-hand threads and must be turned clockwise to loosen).

3.Clean any sawdust that may have accumulated in the guard or clamp washer area and check the condition and operation of the lower blade guard as previously outlined. Do not lubricate this area.

4.Select the proper blade for the application (see Blades). Always use blades that are the correct size (diameter) with the proper size and shape center hole for mounting on the saw spindle. Always assure that the maximum recommended speed (rpm) on the saw blade meets or exceeds the speed (rpm) of the saw.

5.Follow steps 2 through 6 under To Install the Blade, making sure that the blade will rotate in the proper direction.
