8.2.2 Replacing high-pressure hose
Replace high-pressure hoses (operating pressure great-
er than 60 bar) after 3 years (see date of manufacture
on high-pressure hose) even if there are no apparent
defects of relevance to safety.
The high-pressure hose (Fig. 1, item 10) is only to be
replaced by Customer service personnel.
8.2.3 Checking hoses
Always handle hoses (high-pressure and low-pressure
hoses) with care and check before use. Hoses are to be
replaced if checking reveals the following signs of dam-
age:
R
Cracks, brittle areas, abrasion or blistering at the
hose jacket
R
Kinked hoses
R
Stiff union nuts or quick-release couplings
R
Deformed or damaged hose connection end (seal-
ing cone, plug-in nipple, etc.)
R
Leakage at fitting
R
Corrosion at fitting if strength is reduced as a result
!
Damaged hoses are not to be repaired.
8.2.4 Check the protective hood contact
Injection component test must be carried out only with
the protective hood closed. That is why, the protective
hood contact must be checked every day.
1. Start a component test with the protective hood
open.
 Diagnostic trouble code: 9005 Protec-
tive hood appears to be open.
2. Close the protective hood.
 Diagnostic trouble code no longer appears.
 Injection component test can be carried out.
8.2.5 Cleaning jet chamber and ring lamp cover
Clean the jet chamber with a clean cloth to remove
coarse dirt. Wipe over the ring lamp cover inside the jet
chamber with a clean cloth as required.
