5. CHANGING CUTTING DISC
 DaNGER! The use of damaged discs is dangerous and may cause injury.

WaRNING! Ensure that the saw is unplugged from the power supply before attempting to change the cutting disc.
5.1. IMPORTANT! Cutting discs used with this machine must be of an adequate speed rating and suitable for the task in hand.
(See specification). Only persons qualified under the “Abrasive Wheels Regulations” and holding a current grinding wheel
certificate are to change cutting discs.
5.1.1. Before using a cutting disc ensure that there are no fissures or cracks in it. Once mounted on the saw, test the disc before use by facing
the saw in a safe direction (turned away from yourself, others and vulnerable items) and run it for a short time.
5.2. REMOVING AND INSTALLING CUTTING DISCS
5.2.1. Release the arm as described in 4.1. (Remember to hold the arm as it rises).
5.2.2. Identify the spring loaded guard catch as shown in Fig.8.
5.2.3. Open the moving disc guard manually and hold it in the open position whilst moving the spring loaded catch to the right. Rotate
the abrasive disc until you can see a hole in the inner mounting flange. Align this hole with the sprung guard catch and slide the catch
over until it is fully inserted into the hole. (See fig.8). Keep finger pressure on the catch and slowly lower the guard until it rests on the
catch pin. Let go of the guard before letting go of the catch.
5.2.4. Loosen the two fixing bolts as shown in fig.9. The access cover is held under the bolts by a keyhole arrangement. Slide the cover towards
the centre of the wheel and lift it off to reveal the wheel fixing.
5.2.5. Using the 8mm Hex key provided remove the disc fixing bolt, the clamping washer and the front mounting flange as shown in fig.10. Finally
remove the disc from the boss.
5.2.6. Place the new disc over the central boss on the rear flange. Place the front flange onto the raised spigot ensuring that the flats on the flange are
aligned with the flats on the spigot. Retain the assembly with the clamping washer and centre bolt. Do not over tighten the centre bolt.
