Activate extend cylinder after fitting until cylinder shows movement. Reverse cyl-
inder until it returns to start position. Move cylinder backwards and forwards sev-
eral times.
If air is not correctly bled off from the cylinder as described above, there is a risk
that part of the machine can suddenly move much quicker than normal, before the
tractor driver can prevent it. This is because air (unlike oil) is compressible. A side
section can therefore swing out very quickly if air bleeding is not performed cor-
rectly. This represents a major risk of injury to personnel and of damage to the
machine.
Ensure no personnel are within the extension radius of the side sections.
Replacing gaskets
REMOVAL:
1. Drain oil from cylinder, use compressed air to move ram backwards and
forwards (if required) to force oil out.
2. Extend ram to centre position. Screw upper part (3) 30 mm outwards. If
upper part is stuck, heat front of sleeve
to approx. 300

C, and allow to cool.
When upper part has been unscrewed, extend ram towards upper part. Unscrew
and remove upper part, extract ram.
3. Remove lock nut (10).
4. Remove collar shoe (4).
5. Remove upper part from ram (2).
6. Remove gaskets in upper part and collar shoe, (5+6+7+8+9) using an awl or
screwdriver if necessary.
7. Clean all parts, check for particles etc. Check for
rust around scraper ring (5) on the upper part. If any is
detected, remove thoroughly.
