7. turn the bandsaw ON and allow it to reach
full speed, then press the foot brake ( figure
64 on page 38) completely.
— if the bandsaw blade stops, the foot brake
is working correctly; continue to the next
step.
— if the bandsaw blade does not stop mov-
ing, the foot brake feature is not working
correctly. this safety feature must work
properly before proceeding with regular
operations. Call tech support for help.
8. Close the upper and lower wheel covers.
9. turn the switch disabling key to "0", as shown
in figure 48 on page 30.
10. try to turn the machine ON.
— if the bandsaw does not start, the switch
disabling feature is working as designed.
the test run is complete.
— if the bandsaw starts, immediately discon-
nect power. the switch disabling feature is
not working correctly. this safety feature
must work properly before proceeding with
regular operations. Call tech support for
help.
11. Model G0514X3 Only: verify that the power
is not connected out of phase by starting/
stopping the machine and determining if the
motor turns in the correct direction, using the
criteria below:
— if the blade moves down and toward the
table (as standing in front of the machine),
it is turning in the correct direction.
— if the blade turns up and away from the
table, it is turning in the wrong direction.
stop the machine, disconnect the power
source, then swap any two of the three
power wires that connect to the machine.
Tensioning Blade
a properly tensioned blade is essential for making
accurate cuts and is required before making many
bandsaw adjustments. (every time you replace
the blade, you should perform this procedure
because all blades tension differently.)
To tension the bandsaw blade:
1. Complete the Test Run procedure and make
sure the blade is tracking properly.
2. raise the upper blade guide assembly as
high as it will go, and adjust the upper and
lower guide blocks as far away from the blade
as possible.
Note: This procedure will NOT
work if the guide blocks have any contact with
the blade.
3. engage the quick tension lever to the tight-
ened position and turn the blade tension
handwheel until the tension scale reads
between 4 and 6.
4. turn the bandsaw ON.
5. slowly release the tension one quarter of a
turn at a time. When you see the bandsaw
blade start to flutter, stop decreasing the ten-
sion.
6. now, slowly increase the tension until the
blade stops fluttering, then tighten the tension
another quarter turn.
7. look at what the tension gauge reads and
use that as a guide for tensioning that blade
in the future.
Note: Always detension the
blade after use to increase blade life and
reduce strain on the bandsaw components.
8. re-adjust the blade tracking as instructed on
page 23.
