ENGINE SPEED
Measure the engine speed at each power
mode
The engine speed at each power mode
must meet standard RPM; if not, all other
operational performance data will be
unreliable. It is essential to perform this
test first.
Preparation
Warm up the machine, until the engine
coolant temperature reaches 50˚C or
more, and the hydraulic oil is 50
±
5˚C.
Set the multimodal dial at 10 (Max)
position.
Measure the engine RPM.
Measurement
Start the engine. The engine will run at
start idle speed. Measure engine speed
with a engine rpm display.
Measure and record the engine speed at
each mode (P, S, E).
Select the P-mode.
Lightly operate the bucket control lever a
few times, then return the control lever to
neutral; The engine will automatically
enter the auto-idle speed after 4
seconds.
Measure and record the auto deceleration
speed.
