Before performing any service to this machine, turn off the engine. Moving
sawmill parts can cause serious injury or death.
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 the
blade.
Poor sharpening techniques Make sure the tips of teeth are
sharpened properly.
Blades break prematurely
Rubber belts on blade wheels
worn to a point that blade con-
tacts metal pulley - look for
shiny spots on edges of wheels.
Replace the blade wheel belts.
Blade tension too tight Tension blade to recommended
specifications(See "Tension the
Blade.").
Blade does not track right
on wheels
Blade wheel improperly
adjusted
Readjust. (See "Tracking the Blade.")
Flat/worn blade wheel belts Replace the belts.
Drive Belts Wear

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.
