SETTINGS / ADJUSTMENTS
No-load idling adjustment (standard)
Afterhavinglled theenginewith oil andfuel,start it andallowit to

Tightenthechecknut.
No-load top rate adjustment (standard)
Afterhavingadjustedtheidlingrate,usescrew2 andregulatethetop
rateat3800rpm(forenginessetat3600rpmonload).
Tightenthechecknut.
Injection pump ow rate adjustment
Thisregulationmustbecarriedoutbymeansofawaterbrake,other-
wisetheadjustmentwillbeapproximate.proceedinthefollowingway.
Loosenowratelimiter Cby5turns.
Acceleratetheenginetono-loadtoprate,i.e.to3800rpm.
Re-tightenlimiterC untiltheenginetendstodecelerate.

andiftheengineisunabletodevelopitsmaximumpower.
Injection pump delivery limiting and torque adapter (standard)
DeliverylimitingdeviceChasthefunctionoflimitingtheinjectionpump
max.delivery.
Thesame device also acts astorque adapter. The speedgovernor
springactsonlever L withstandingtheresistanceopposedbyspring
Minsidethecylinder.
ThestrokeHallowedbythetorquedevicetoleverLis0.20/0.25mm.
Asaresultofthispumpdeliveryincreasesandtorquereacesitspeak
value.
Note:Ingeneratorsetsandpowerwelders,thetorquesettingdevice
actsasadeliverylimiteronly.
