INSTALLING THE BLADE

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.
Wear ANSI Z87.1 safety glasses while using compressed air.
