Inspection and adjustment
Adjusting the unit-injector
1. Slacken the lock nut of the adjusting bolt.
2. Turn the adjusting bolt three to four times
clockwise and anti-clockwise. This will force
the fuel beneath the injector plunger out,
thus moving the injector plunger
downwards.
3. Then screw the adjusting bolt clockwise
until there is clear, considerable resistance.
Do not turn the adjusting bolt further in
clockwise direction to avoid damage.

tighten the lock nut to the specified
tightening torque, see "Technical data".
