To prolong blade life, always use a blade with 

the proper width, set, type, and pitch for each 

application. Maintain the appropriate feed rate, 

feed pressure, and blade speed and pay attention 

to the chip characteristics (Refer to the Chip 

Inspection Chart on Page 26). Keep your 

blades clean, since dirty or gummed up blades 

pass through the cutting material with much 

more resistance than clean blades, causing 

unnecessary heat.

The tips and edges of a new blade are extremely 

sharp. Cutting at too fast of a feed rate or too 

slow of a blade speed can fracture these tips 

and edges, quickly dulling the blade. Properly 

breaking-in a blade allows these sharp edges 

to wear without fracturing, thus keeping the 

blade sharp longer. Below is a typical break-in 

procedure. For aftermarket blades, refer to the 

manufacturer's break-in procedure to keep from 

voiding the warranty.

Use the Chip Inspection Chart on Page 26 as 

a guide to evaluate the chips and ensure that the 

optimal blade speed and feed rate are being used.

1.  Choose the correct speed for the blade and 

material of the operation.

2.  Reduce the feed pressure by half for the first 

50–100 in

2

 of material cut.

3.  To avoid twisting the blade when cutting, 

adjust the feed pressure when the total 

width of the blade is in the cut.

Start and stop downfeed with the downfeed knob. 

The downfeed rate is adjusted by turning the 

downfeed rate adjust knob (Figure 24). Turning 

the knob clockwise decreases the downfeed rate 

and turning the knob counterclockwise increases 

the downfeed rate. 

The downfeed pressure is controlled by the 

spring shown in Figure 25.

To decrease downfeed pressure, turn the cap 

screw clockwise to increase spring tension.

To increase downfeed pressure, turn the cap 

screw counterclockwise to release spring tension.
