SOLUTION

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.

Height Adjustment Jumps or 
Stutters When Moving Up or 
Down.

Up/down chain improperly 
adjusted.

Adjust up/down chain.

Vertical wear pads are too 
tight.

Adjust pads.

Up/down belt loose.

Replace belt.

Lumber Is Not Square

Vertical side supports not 
square to bed

Adjust side supports.

Blade not parallel to bed rails

Adjust bed rails parallel to blade.

Sawdust or bark between cant 
and bed rails

Remove particles

Tooth set problems

Resharpen and reset blade

Sawdust Builds Up On Track

Excessive oiling

Do not oil track

Track wipers worn

Adjust wipers to firmly contact track

Track is sticky

Clean track with solvent and apply 
silicone spray

Wavy Cuts

Excessive feed

Slow feed rate

Improperly sharpened blade 
(This will be the problem 99% 
of the time!)

Resharpen blade (See Sharpener 
Manual - read entire manual!)

Blade guides improperly
