CHANGING THE BLADE (See Fig.12)

This saw is designed to work with the following size of

blade only, 2460 x 27 x 0.9mm. Fitting any other size may

result in serious injury and will invalidate your warranty.

The following blades are available from your local Sealey

dealer:

Part Number

2460 x 27 x 0.9mm

4.9.1 The black protective cover on the back of the bow casting is

held in place by four thumb screws with the addition of a flat

actuator blade that passes into a safety switch mounted on

the end of the casting below the motor (See Fig.13).

4.9.2 Loosen and remove the four thumb screws. Continue to hold

the cover in place and take hold of the bottom edge adjacent

to the safety switch. Ease the cover away from the casting

until the the flat actuator blade withdraws from the safety

switch. The cover can now be removed and put to one side.

4.9.3 Before the saw blade can be changed the blade safety

guards must be removed from the blade guides. See 'C' & 'D'

in Fig.12) Use a 5mm hex key to remove the socket cap bolts

that hold the blade guards in place.

4.9.4 Release the tension on the blade by turning the blade tension

wheel 'G' anticlockwise until the blade is loose enough to be

removed from the flywheels. See 'E' & 'F' in Fig.12.

4.9.5 Ease the blade out of the blade guides. See 'A' & 'B' in Fig.12.

4.9.6 When fitting the new blade ensure that it is the correct way

round so that the teeth are cutting left to right as you face the

machine. See blade tooth label on the front lower part of the

bow casting. See 29 in Fig.4 .

4.9.7 Feed the new blade into the blade guides first, then ease it

onto the flywheels. The blade should be close to, but not hard

up against the rim on each flywheel.

4.9.8 Refix the blade guards to the appropriate blade guides.

4.9.9 Retension the blade by turning the blade tension wheel

clockwise until the back of the wheel makes contact with and

operates the microswitch adjacent to it. See Fig.14.

4.9.10 Refit the protective cover onto the back of the bow casting

and retain it with the four thumb screws previously removed.

Ensure that the flat actuator blade at the lower end of the

cover has entered the microswitch housing as shown in Fig.13.

4.9.11 Move the bow down to its lowest position. Reconnect the

bandsaw to the mains power supply. Switch the machine on

and run it for a short while to allow the blade to bed in.

4.9.12 If the machine fails to run, disconnect the bandsaw from the

mains power supply and investigate the two safety switches.

Firstly check that the actuator on the cover has correctly

entered the safety switch. Alternatively the blade tension

wheel may be touching the microswitch behind the wheel

flange but has not fully operated the switch. See Fig.14. Turn

the blade tension wheel a further half turn clockwise.

Reconnect to the mains power supply and switch on to test.
