Porter-Cable 837, 8823 instruction manual Selecting the Blade, Installing the Blade

ASSEMBLY

NOTE: This tool is shipped completely assembled. No assembly time or tools are required.

SELECTING THE BLADE

For best performance, longer blade life, and smoother cut, select the proper blade for the job. When cutting metal, always select a blade that will allow at least three teeth to be engaged in the thickness of workpiece.

INSTALLING THE BLADE

1.Fully extend the reciprocating shaft to permit access to the Quik-Change™blade release collar (A) Fig. 3. If necessary, gently squeeze the trigger switch to move the reciprocating shaft to its outermost position (Fig. 5).

REMOVE THE BATTERY.

Avoid contact with the blade teeth to prevent personal injury.

2.Move the guide shoe (B) Fig. 3 forward to access the blade clamp.

3.To open the blade clamp, rotate and hold the blade release collar (A) Fig. 4 counter-clockwise (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 (see Fig. 5).

5.To remove the blade, first remove the battery. Then reverse steps 2 through

4.Pull the blade from the blade clamp while holding the release collar in the open position.

NOTE: If the blade clamp collar resists rotation, 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), use another blade as a tool to remove the broken piece (Fig. 6). 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 will cause contamination.
