5. Use a tie strap as shown below to secure the hood
support when the hood is being installed.
6. Carefully lift the engine hood assembly onto the
hood support.
NOTE: The engine hood assembly weighs approximately 84
lbs. (38 kg).
7. Install the bolts and clamps that secure the engine
hood assembly to the hood support.
8. Start the engine and check for proper operation and
any leakage. If the engine does not start immedi-
ately, the fuel lines may need primed.
NOTE: The delay in starting the engine can be reduced by
removing the fuel filter, pre-filling the filter with fuel,
and reinstalling the filter before attempting to start
the engine.
3.27 DEUTZ EMR 2 (S/N 87575 TO PRESENT)
NOTE: S/N’s 85693 & 85910 also incorporated EMR2.
The EMR2 consists of the sensors, the control unit and the
actuator. Engine-side controls as well as the JLG Control
System are connected by means of separate cable har-
nesses to the EMR control unit.
The sensors attached to the engine provide the electron-
ics in the control unit with all the relevant physical parame-
ters In accordance with the information of the current
condition of the engine and the preconditions (throttle
position etc.), the EMR2 controls an actuator that operates
the control rod of the injection pump and thus doses the
fuel quantity in accordance with the performance require-
ments.
The exact position of the regulating rod is reported back
and, if necessary, is corrected, by means of the control
rod travel sensor, situated together with the rotation mag-
nets in a housing of the actuator.
