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.

5.9.1.
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 behind the motor (see fig.13).
5.9.2.
loosen and remove the four thumb screws. continue to hold the cover in place and take hold of the 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.
5.9.3.
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.
5.9.4.
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.
5.9.5.
Ease the blade out of the blade guides. See ‘A’ & ‘B’ in Fig.12.
5.9.6.
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.
5.9.7.
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.
5.9.8.
refix the blade guards to the appropriate blade guides.
5.9.9.
tension the blade by turning the blade tension wheel clockwise until the back of the wheel makes full contact with the group of conical
washers behind it on the threaded shaft. See ‘H’ in Fig.12. Tighten the wheel 1 ½ turns. See section 7 ‘Troubleshooting’ regarding blade
tension problems.
5.9.10.
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 end of the cover has entered the microswitch housing as shown in fig.13.
5.9.11. 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.
5.9.12. 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. turn the blade tension wheel a further half turn clockwise.
reconnect to the mains power supply and switch on to test.
