Bottom clamp
Using a suitable instrument, such as a flat-bladed screwdriver, carefully remove the hole plug
(21.6) (Fig 10).
Remove the retaining screw (21.5) and washer (21.4), but do not remove the clamp knob (21).
Rotate the clamp knob (21) to ‘position 2’ shown in (Fig 10), with the edge of the clamp knob (21)
vertical. In this position the clamp is NOT fully rotated counterclockwise in the ‘off’ position.
Using a 2.5 mm hexagonal wrench, loosen the adjusting grubscrew (21.3) until the leg is free to
move under its own weight.
While sliding the leg in and out, gradually tighten the adjusting grubscrew (21.3) until the clamp
begins to grip.
Rotate the clamp knob (21) fully counterclockwise to the ‘off’ position and ensure that the leg is
free to move under its own weight.
Secure the clamp knob (21) with the washer (21.4) and retaining screw (21.5). Refit the hole plug
(21.6).
