Sawing Problems

PROBLEM

CAUSE

SOLUTION

Blades Dull Quickly

Dirty logs

Clean or debark logs, especially 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

Rubber belts on blade wheels worn to
a point that blade contacts metal
pulley - look for shiny spots on edge
of wheels

Change blade wheel belts (B-57)

Poor sharpening techniques

See Sharpener Manual

Tension too tight

Tension blade to
recommended specifications

Blade Does Not Track Right
on Drive Wheel

Cant adjustment is incorrect

Readjust

Flat/worn belts

Replace B-57 belts

Blade Guides Do Not Spin
While Cutting

Frozen bearings

Replace bearings

Stiff bearings

Grease bearings

Blade Does Not Stop
Immediately After
Disengaging

Brake strap too loose

Adjust brake strap

Drive Belts Come Off Pulleys
When Disengaging Blade

Brake strap too loose

Adjust brake strap

Brake drum misaligned

Realign on drive shaft

Brake strap tightened with one edge
too loose and one edge too tight

Adjust brake strap

Drive Belts Wear Prematurely
or Jump

Engine/motor and drive pulleys out of
alignment

Align pulleys.

See Section 4.5

Engine/Motor and Drive Pulleys
Alignment.
