WARNING! Turn off the machine and disconnect it from the
mains power supply before removing the safety cover from the
rear of the bow casting. Wear safety gloves when handling saw
blades as the teeth are very sharp.

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
SM355B14
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.
