Do not rotate the PLA unit over 1/2 turn from the
position marking. If do, idle spring in the governor
will be severely damaged.
6. After adjustment, tighten the locking nut and place
the position marking with different color of paint.
Notice
If there are no changes in idle speed with PLA unit
adjustment, perform the service at a BOSCH Ser-
vice Center.
7. Connect the vacuum pump to the PLA vacuum unit
and build up vacuum approx. 500mbar. If engine
rpm increases by approx. 100rpm, It is normal.
