1 Before starting up check all screws 36
• Use the Allen key provided to loosen all four of the 36 screws
by one rotation.
• Then slightly tighten the screws again, e.g. by holding the
Allen key between the thumb and index finger only.
• Finally tighten all four screws by a quarter rotation.
• Always tighten opposing screws, i.e. tighten one screw and
then the opposite screw.
• Avoid overtightening the screws as this could damage the
