Porter-Cable 740 Cordless Saw User Manual


 
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).
NOTE: 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.
WARNING: Wear safety glasses while using compressed air.
