0000001801 M-CSD ADJUSTMENT
M-CSD adjustment
1. Fixing the M-CSD
(1)At roller holder advance angle a adjust the lever shaft ball pin so that it contacts the roller holder.
(2)At this time, adjust the position of the M-CSD lever (A) using adjusting screw (C) so that the clearance between the M-CSD lever (A) and the stopper (B) becomes L1. Then fix using nut (D).
TT
2. M-FICD adjustment
(1)Move the CSD lever (A) through its full stroke.
(2)Adjust screw (E) so that the control lever (G)'s position is b (the clearance between the control lever and the idling set screw is L2). Then fix using the nut (F).

ACS adjustment
Full load injection quantity at high altitudes and ACS adjusting method
1. Full load injection quantity adjustment
(1)Remove the ACS cover and remove the bellows and adjusting shim.
(2)Perform all adjustments as per the adjustment standard except for ACS adjustment.
2. ACS adjustment
(1)Assemble the ACS cover, bellows and adjusting shim.
(2)At pump speed N1, adjust using a shim to obtain the decrease for the altitude shown in the table.
Adjustment of the V-FICD
(1)Operate the V-actuator through its full stroke.
(2)Adjust the V-actuator screw so that the control lever position is a (clearance from the screw is L).

Information:
Stopping the engine immediately after it has been working under load can result in overheating and accelerated wear of the engine components. Allow the engine to cool down before stopping. Avoiding hot engine shutdowns will maximize turbocharger shaft and bearing life.
Emergency Stopping
Emergency shutoff controls are for EMERGENCY use ONLY. DO NOT use Emergency shutoff devices or controls for normal stopping procedure.
Make sure that any external system components that have been operating to support engine operation are secured after any stop.Emergency Stop Buttons
Emergency Stop Button, shown mounted on a junction box.Emergency stops may be made by pushing the Emergency Stop Button located on the junction box (if equipped). Both the Button and the air inlet shutoff (if equipped) require resetting before the engine will start.
Control Panel Emergency Stop Button.If equipped with the EMCPII Control Panel, press the Emergency Stop Button for an emergency stop. The ECS must be reset before resuming operation. Move the ECS to the OFF/RESET position. The ECS can also be used to shut the engine off in an emergency. Move the ECS to the OFF/RESET position. The engine will immediately shut off.Manual Stopping
A manual shutoff shaft is provided to override the governor control. The shaft will move the fuel control linkage to the FUEL OFF position. Refer to the Model Views for the engine location of the shaft. The engine may be stopped by using the shaft and the Woodward Actuator (if equipped) or the Mechanical Governor (if equipped).
Typical Woodward Actuator Control Lever.If equipped with a Woodward Actuator, move the control lever to the FUEL OFF position.
Typical Mechanical Governor ControlIf equipped with a Mechanical Governor Control, move the control to the FUEL OFF position.Hold the lever at the FUEL OFF position until the engine stops.Air Shutoff (If Equipped)
Some engines are equipped with an air shutoff, located between the aftercooler and the turbocharger. If equipped with an air shutoff lever, move the lever to the OFF position.Manual Stop Procedure
There may be several ways to shut off your engine. Make sure the shutoff procedures are understood. Use the following general guidelines for stopping the engine.EPG Engines
If the ECS is in the AUTO position and the remote contact opens, the engine will run for a pre-programmed cool down period. This will only occur when the cool down mode is used. If the cool down mode is not used, the engine will shut off immediately.
If the ECS is in the AUTO position, the remote contact opens, and the cool down time expires, the CTR will be unlatched and the starting motors may be re-engaged.1. Open the main electrical circuit breaker to remove the load.2. The engine should be run for a cool down period before being shut off. This can be accomplished with the COOLDOWN STOP switch, or the operator can control the cool down and shut off.
To use the COOLDOWN/STOP switch, turn the ECS to the COOLDOWN/STOP position. The engine will operate for a pre-programmed time period. The timer will active the fuel shutoff after the cool down.Alternatively,
