Clamping lever
adjustment
1. Start a paper feed and check that the clearance between the camshaft and
the paper transport shaft is 25 + 0.5 mm.
If aligned correctly, the tip of the support clip points to the center of the
paper transport shaft. You should also be able to press the clamping lever
down by 0.5 mm.
2. Adjust if necessary with the setting nut and secure with the lock nut (see
Fig. 12
on page 26).
– If the clearance is too large, the retaining ring does not open wide
enough and there is a risk that soot will be scraped off.
– If the clearance is too small, the leakage factor will be high because
the clamping force is insufficient.
3. Check the friction in the tracks/bearings of the ratchet clip-camshaft in rela-
tion to one another and:
– If necessary, lubricate track (ex-works: Teflon lubricant spray - material
number HS0058, Teflon lubricant oil - material number HS0064, or
Lubricant grease OKS 260 - material number HS0071); see
chapter 13
in the Operating Manual
