Test Run
Once assembly is complete, test run the machine
to ensure it is properly connected to power and
safety components are functioning correctly.
If you find an unusual problem during the test run,
immediately stop the machine, disconnect it from
power, and fix the problem BEFORE operating the
machine again. The
Troubleshooting table in the
SERVICE section of this manual can help.
To test run machine:
1. Make sure you understand all safety instruc-
tions at the beginning of manual and that
machine is set up properly.
2. Make sure all tools and objects used during
setup are cleared away from machine.
3. Connect saw to power.
4. Push Emergency Stop button, then twist it
clockwise so it pops out. When button pops
out, switch is reset and will allow operation
(see
Figure 70).
Figure 70. Resetting Emergency Stop button.
DO NOT start machine until all preceding
setup instructions have been performed.
Operating an improperly set up machine
may result in malfunction or unexpect-
ed results that can lead to serious injury,
death, or machine/property damage.
The test run consists of verifying the following:
1) The motors power up and run correctly, 2) the
safety features of the Emergency Stop buttons
work correctly, and 3) the main blade turns for-
ward (clockwise when viewed from front of saw)
and the scoring blade turns opposite main blade.
5. Verify saw is operating correctly by pushing
Main Blade and Scoring Blade ON buttons
(refer to
Figure 4 on Page 5).
—When operating correctly, machine runs
smoothly with little or no vibration or rub-
bing noises.
— Investigate and correct strange or unusu-
al noises or vibrations before operating
machine further. Always stop machine and
disconnect it from power before investigat-
ing or correcting potential problems.
6. Verify main blade is rotating clockwise (as
standing in front of machine) and scoring
blade is rotating counterclockwise (opposite
direction as main blade).
Note: You may need to stop the blade rota-
tion and watch them come to a stop to deter-
mine which direction they are rotating.
— If blades are rotating in wrong direction,
stop machine and DISCONNECT FROM
POWER! Polarity of incoming power sup-
ply is reversed. Swap “R” and “T” wire
positions inside junction box (see
Figure
71), then replace junction box cover, and
reconnect machine to power.
