1.9 ORDERING SPARE PARTS
On principle spare part numbers should be taken from the drawings or spare parts lists. Check if the version
number of the tool and the spare parts list are the same.
Type dependent spare parts should be ordered as follows:
Ordering example
Ordering a tensioning wheel:
• Take item numbers of the tensioning wheel from drawing (P33.2229/30)
• Find out the tool type in which the tensioning wheel should be assembled (e.g. 43.0296)
• Find out the item number of the needed tensioning wheel by using the type dependent spare
parts lists (for type 43.0296 it is tensioning wheel P33.2229).
Order as follows if 10 tensioning wheels are needed:
P33.2229 Tensioning wheel 10 pcs.
1.9.1 Ordering manuals
When converting tools make sure that the used manual has still validity.
If tools change their item number because of the conversion (see chart of types) the adequate manual must
be ordered as follows.
