Set-Up and Operation
E. Tensioning the Blade on all Models
NEVER tension your blade with the engine running. Your mill is shipped to you with
minimal, if it is too loose it falls off during transit. If there is tension left on the blade
for a period of time, it can cause flat spots in the bandwheel belt. After putting a new
blade on, check tension after the first cut.
This will cause the blade to fall off the wheel. Always remember to de-tension your
blade when you are done sawing for the day.
1. Make sure blade is flush with back of bandwheel.
2. To tension or loosen the blade, see figure below.
3. Turn the adjusting bolt or stud, clockwise until 30-35 pounds of torque is achieved.
The recommended tool for this is a torque wrench. By hand, rotate blade 3-4 full
revolutions; this centers the blade on the wheels.
4. With gloves on, pull up on the blade at the center guard. Allow for no more than a
¼" movement up or down on the blade.
5. Blade guides must not be so tight they cause the blade to heat up. If this occurs re-
adjust guides.
6. Perform a simple test call the "Flutter" test. Put the guards on and then run the
engine at full RPM's (be sure the blade is not in a cut during this test) and watch the
blade under the blade guard. The blade must run straight, if it does not, shut the
engine down and apply more tension. Keep in mind that over tensioning will also
cause the blade to flutter. You should have attained proper tension around 30-35
pounds.
