Test Run
Each jointer has been inspected and calibrated before leaving the factory to meet our quality and precision
standards. Due to various reasons, this jointer may need to be re-adjusted when it arrives at your
workshop. It is recommended to complete this test run before using the jointer for production work, and
repeat if the jointer is relocated.
Complete these quick tests to verify components are functional.
1. Remove all tools and debris from the
machine. Ensure the jointer is disconnected
from the power source.
2. Set the fence to 90 degrees. Move and lock
the fence all the way back to expose the
entire jointer table. Ensure the cutterhead
guard is pushing against the fence. Rotate
the guard to expose the entire cutterhead,
then gently release the guard. The
cutterhead guard should spring back to its
original position.
WARNING: If the cutterhead guard fails to
push against the fence, STOP HERE. Adjust
guard tension before resuming the test run.
3. Use the provided key to turn the main switch
to the OFF position, and press the
emergency STOP button.
4. Connect the machine to the power source.
5. Press the START button. The machine should
not turn on.
6. Turn the main switch to ON, and press the
START button. The machine should not turn
on.
7. Reset the emergency STOP switch by
rotating it clockwise. The button should pop
up. Press the START button, and the
machine should turn on. The machine
should be running with no excessive noise
and vibration.
8. Disconnect the machine from the power
source while it is running, then reconnect
the machine to power. The machine should
NOT restart.
9. Turn on DRO. Rotate the infeed table
adjustment handwheel to raise/lower the
infeed table.
DRO’s readings should reflect
movements of the table, and the table
should stop at 1/8” when is lowered without
disengaging the depth stop.
10. Set infeed table depth of cut to 1/32 ”.
11. Turn on the dust collection system, and
surface plane a test workpiece. See section
“ Surface Planing ” on page 32 for detailed
instructions. The workpiece should move
through the jointer with ease.
12. Inspect the workpiece for unusual tear outs
and other defects.
Congratulations! You have completed the test run! Now your jointer is ready for production work. If you
