INSTALLING THE BLADE MODELS 746 and 748 with Keyless Quik-Change™Blade Clamp

1.The reciprocating shaft must be fully extended to permit access to the Quik-Change™blade release collar (A) Fig. 4. If necessary, gently squeeze the trigger switch to move the reciprocating shaft to its outermost position (as shown in Fig. 4).

Disconnect tool from power source.

2.Pivot the guide shoe (A) Fig. 6, forward to improve access to the blade clamp (B) Fig. 6.

3.To open the blade clamp: rotate and hold the blade release collar (A) Fig. 7, counterclockwise (as viewed from the front of the saw).

4.Insert the blade into the clamp until it bottoms. Allow the release collar to rotate clockwise to lock the blade in place, (A) Fig. 4.

5.To remove blade: repeat steps 1 through 3, and pull blade from blade

clamp (while the release collar is being held in the open position).

Never touch blade immediately after use, as it may be extremely

hot.

NOTES: If the blade clamp collar resists rotation to remove a blade, work the blade up and down while rotating the clamp (in a counter- clockwise direction).

If the blade breaks leaving nothing to grasp (to pull it from the clamp), it may be necessary to use another blade as a tool to aid in removing the broken piece (see Fig. 5). While holding the release collar in the open position, use the tip of another blade to “hook” the broken piece and pull it from the clamp. (A thin, fine-toothed, metal- cutting blade works best.)

Periodically clean the blade clamp with dry compressed air. DO NOT lubricate the blade clamp. Lubricant can attract contamination.
