11.1 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 bandwheel doors by turning the star handle
Fig 11.3 (14)
.
3.
Remove the Hex socket screw and keep plate from the underside of the
table,
Fig 11.1
.
4.
Move the blade tension cam handle clockwise to release the blade
tension.
Fig 11.3 (17)
.
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 bandwheel. Simply re-apply
tension using the cam handle lever.
• Fine adjust the blade tension further if required using the blade
tension wheel.
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
bandwheel as possible. On 1/4", 3/8" and 1/2" blades it may be necessary
to run the blade to rear of the bandwheel
(see section 6.2.)
7.
If required adjust the tracking using tracking knob
(15)
and lock knob to
the rear of the upper bandwheel housing. When the tracking is correct lock
the setting.
8.
Re-set the blade guides.
9.
Close and lock both the bandwheel doors before re-connecting the
power supply.
CAUTION!
Before carrying out any adjustments or maintenance ensure
that the machine is isolated and disconnected from the
electricity supply.
