Tensioning The Blade
See Figure 3-14.
Before tensioning the blade, check the air pressure gauge to see that
the air tension system is properly charged. With the blade tension completely released
and the air bag plate against the stop bolt, the gauge should read 85 psi for all blade
types. To add air pressure, remove the air valve stem cover and attach an air pump to the
air valve. Add air until the gauge indicates the proper air pressure. To release air, push in
the valve stem. Replace the air valve stem cover when finished adjusting the air pressure.

To tension the blade, turn the release valve
clockwise to close. Pump the lever until the air bag plate is approximately 1/8" (3.0mm)
from the stop plate.
To release blade tension, turn the release valve counterclockwise to open. Pry the
assembly forward until the blade can be removed.

Lower the release valve han-

clockwise to open. Pump the lever until the air bag plate is approximately 1/8" (3.0mm)
from the stop plate. Turn the blocking valve clockwise to close. Raise the release valve
handle (move the handle away from the sawmill operator) to release pressure from the
