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.

Drive Belts Wear Prematurely
or Jump.

Engine/motor and drive pulleys out
of alignment.

Align pulleys.
