General note:

7.1 Changing the sawblade

The sawblade has to meet the technical specification.
Choose a suitable sawblade, according to the cutting operation
and according to the material to be cut.
For high rip cuts:
- use a wide sawblade (e.g. 15mm), coarse teethed.
For narrow curved cuts:
- use a narrow sawblade (e.g. 6mm).
Check sawblade for flaws (cracks, broken teeth, bending)
before installation. Do not use faulty sawblades.
The sawblade teeth must point in cutting direction (down)
Always wear suitable gloves when handling sawblades.
The sawblades may only be changed when the mains plug is
pulled!
Replacing the bandsaw blade
1. Isolate the machine from the supply, pull the mains plug
2. Open the top and bottom bandwheel doors by turning the
door locks (A, Fig 21) with a flat bladed screwdriver.
3. Remove the Rip fence guide (B) from the front of the table
by releasing the 4 winged screws (C).
4. Release the blade tension by turning the large knob (D).
5. Remove the sawblade (E) by feeding it through the slot in
the table, upper blade guides and guard and the slot in the
spine of the machine taking care not to cut yourself, wear
gloves if necessary.
6. When fitting the new blade ensure the blade teeth are
pointing downwards and towards you at the position
where the blade passes through the table.
7. Re-tension the new blade and check the blade tracking by
turning the upper wheel by hand. The blade should run in
the centre of the bandwheel. (see Fig 23)
8. If required adjust the tracking using tracking knob and lock
knob (F, Fig 22) to the rear of the upper bandwheel
housing. When the tracking is correct lock the setting.
