6. Adjust the width of the air gap "a" as
follows:
- Use an open-ended spanner to
turn the three hollow adjusting bolts
(6) further into the stator. Ensure
that these bolts are all screwed
into the stator by the same amount.
- Use a feeler gauge to measure the
width of the air gap "a" close to
each of adjusting bolts and turn the
bolts until the gap by each bolt is
just 0.3 mm / 0.012 in wide.
The adjustment of the hand
release may not be changed, not
even when air gap "a" is
readjusted, as security can be
adversely affected.
7. Mount the rubber dustring, the fan
cover and the brake lever.
