10.1 Replacing the bandsaw blade
HAZARD!
Take great care when unpacking the bandsaw blade as they are
usually folded and can spring out very suddenly with great force.
TIP:
If the new blade being fitted is a different width to the one being
removed, it is advisable to move back and slacken off all blade guides
before fitting the new blade as this will make fitting easier. Whenever a
different size blade is fitted the blade guides will always need re-setting.
1.
Isolate the machine from the power supply.
2.
Open the top and bottom band wheel doors by unscrewing the hex
socket screw,
Fig 10.3 (14)
.
3.
Remove the Hex socket screw and keep plate from the underside of the
table
Fig 10.1
.
4.
Turn the blade tension knob
(17)
to release the blade tension.
5.
Remove the bandsaw blade by feeding it through the slot in the table,
upper blade guides and guard and slot in the spine of the machine taking
care not to cut yourself, wear gloves if necessary.
• Fit the new blade ensuring the blade teeth are pointing downwards and
towards you at the position where the blade passes through the table.
• Ensuring that the blade is fully in place on band wheel. Simply re-apply
tension using the tension knob until the tension indicator shows the correct
tension for the blade width.
• Adjust the blade tension further if required using the blade
tension knob.
6.
Check the blade tracking on the newly fitted blade by turning the upper
wheel by hand. The blade should run as close to the centre of the band
wheel as possible. On 1/4", 3/8" and 1/2" blades it may be necessary to
run the blade to rear of the band wheel
(see section 6.2.)
7.
If required adjust the tracking using tracking knob
(15)
and lock knob to
the rear of the upper band wheel housing. When the tracking is correct lock
the setting
(see section 6.2)
.
8.
Re-set the blade guides
(see sections 6.3 & 6.4)
9.
Close and lock both the band wheel doors before re-connecting the
power supply.
The blade tension indicator is a guide only and may need re-calibrating
periodically. For further information on blade tensioning
see section 6
.
If the blade teeth are pointing the wrong way simply twist the blade inside
out. Remember to always check the guides after changing any blade.
CAUTION!
Before carrying out any adjustments or maintenance ensure
that the machine is isolated and disconnected from the
electricity supply.
