Changing discs
Make sure the implement rests properly on solid supports. When replacing discs, use a ratchet
wrench or better still a nutrunner. Block the disc using a wood block or similar to prevent it from
turning. The discs have sharp edges - use gloves! Tighten the pinned head screws crosswise to a
torque of 105 Nm.
