■ Follow carefully the instructions given in the machine handbook.
■ Never fit a flap disc which is too loose or too tight on the flange.
■ Align the outer flange correctly as shown in the FEPA Safety leaflets for flap discs used on angle grinders (under development)
■ Tighten only with the tool supplied with the machine.
■ Ensure the disc is properly gripped to prevent slippage, but do not tighten with excessive force. Never use a hammer.
■ Keep flanges and screw threads clean and free of burrs and rust.
■ Replace distorted or damaged flanges before fitting the disc.
■ Refer to the FEPA recommended mounting check list.
