SECTION 7 TROUBLESHOOTING GUIDE

7.1 Sawing Problems

WARNING!

Turn the key switch to the OFF (0) position and remove

the key before performing service near moving parts such as blades,

pulleys, motors, belts, and chains. If the key is turned on and moving

parts activated, serious injury or death may result.

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: Read the instructions

with your blade sharpening equip

ment carefully

Blades break prematurely

Poor sharpening techniques

Read the instructions with your blade

sharpening equipment carefully

Rubber belts on idle blade

wheel worn to a point that

blade contacts metal pulley -

look for shiny spots on edge of

wheels

Change idle blade wheel belts

Tension too tight

Tension blade to recommended

specifications

Blade does not track right on

drive wheel

Cant adjustment is incorrect

Readjust

Blade guides do not spin

while cutting

Frozen bearings

Replace bearings

Drive belts wear prematurely

or jump

Engine/motor and drive pul

leys out of alignment

Align pulleys

Boards thick or thin on ends

or middle of board.

Stress in log which causes log

to not lay flat on the bed.

After log has been squared, take

equal cuts off opposing sides. Take a

board off the top. Turn the log 180

degrees. Take a board off. Repeat,

keeping the heart in the middle of the

cant, and making it your last cut.

Set in teeth.

Resharpen and reset blade.

Bed rails misaligned.

Realign sawmill bed.
