TESTING AND ADJUSTING
INSPECTION AND ADJUSTMENT OF ENGINE SPEED
INSPECTION AND ADJUSTMENT OF ENGINE SPEED a Engine inspection and maintenance tools Mark 1 A 2
Part No. 799-205-1100 795-790-2500
Part name Tachometer kit Take off drive
2. Fit take off drive A2, and connect pickup set [1] and meter [2] of tachometer kit A1.
a Engine speed may be detected using a monitoring function in the monitor panel (special function furnished to the monitor panel).
k Be careful not to touch the strongly heated portion of the engine by accident while installing a measurement equipment. Inspection 1. Open up the engine hood and take off cover (1). a Use a filter wrench to take off the cover.
20-102 (12)
3. Measure the engine speed after setting each measurement condition. 1) Engine speed at low idle: i) Set the fuel dial at low idle (MIN). ii) Move all the control levers of work equipment, swing and travel to the NEUTRAL position. 2) Engine speed at high idle: i) Turn the auto-decelerator OFF. ii) Set the fuel dial at high idle (MAX). iii) Move all the control levers of work equipment, swing and travel to the NEUTRAL position. 3) Engine speed at fuel pump relief i) Set the fuel dial at high idle (MAX) ii) Put the arm in the digging relief position. 4) Engine speed when 2 pump relief and onetouch power max. switch are set (near rated engine speed) i) Set the fuel dial at high idle (MAX). ii) Put the arm in digging relief position and keep the one-touch power max. switch depressed. a The one-touch power max. function is automatically released in 8.5 seconds, even if the knob switch is kept depressed. Take measurement during the period.

TESTING AND ADJUSTING
INSPECTION AND ADJUSTMENT OF ENGINE SPEED
5) Engine speed when auto-decelerator is set i) Turn the auto-decelerator ON. ii) Set the fuel dial at high idle (MAX). iii) Move all the control levers of work equipment, swing and travel to the NEUTRAL position. a Approx. 5 seconds after all the control levers are moved to the NEUTRAL position, the rpm falls automatically. That is when the rpm with the auto-decelerator in motion should be measured.
4. Detach all the measurement tools after the inspection, and make sure that the machine is back to normal condition. Adjustment 1. Adjustment of engine speed at low idle a If the rpm at low idle deviates from the standard value, make adjustment using the adjustment function provided in the monitor panel. a For the adjustment procedures, refer to the section, "Special function of monitor panel" 2. Adjustment of governor spring a If the rpm at high idle deviates from the standard value, or it is unsteady (hunting), adjust the governor spring securing dimensions, using the adjustment function in the monitor panel. a For the adjustment procedures, refer to the section, "Special function of monitor panel"
