Sawing Problems

PROBLEM

CAUSE

SOLUTION

Blades Dull Quickly

Dirty logs

Clean or debark logs, espe-
cially on entry side of the cut

When grinding teeth, heating 
too much and causing teeth to 
soften

Grind just enough metal to 
restore sharpness to the 
teeth. Use water/coolant while 
sharpening blade

Poor sharpening techniques

Make sure the tip is being 
sharpened completely (See 
Sharpener Manual)

Blades Break Prematurely

Poor sharpening techniques

See Sharpener Manual

Tension too tight

Tension blade to recom-
mended specifications

Blade Does Not Track Right 
on Drive Wheel

Cant adjustment is incorrect

Readjust 

Drive Belts Wear Prematurely 
or Jump

Engine/motor and drive pul-
leys out of alignment

Align pulleys 

See Section 7.6
