2.3 Engine speed
[NOTICE]

Before checking the engine speed, run the engine
to warm it up. (Temperature of the torque converter
oil should reach approximately 50°C (122°F).)

2.4 Procedure for checking engine stall speed
If engine output power decreases or torque
converter oil is heated significantly, check the
engine stall speed as follows:
1. Set the switches and controls as described below.
• PTO switch : OFF
• Shift lever :”2” (High 2nd)
• Drive mode selection switch : 6WD/High (*1)
• Service brake : ON
• Emergency transmission switch:
"ON" with "6WD/High" state (*2)
(*1) Because the drive mode cannot be changed after
the emergency transmission switch is turned ON,
change to "6WD/High" in advance.
(*2) Emergency operation switch inside electrical box
in the cab rear
2. While depressing the brake pedal, depress the
accelerator pedal all the way. Check the engine
speed.
Max. speed standard when stalled:
Approximately 1760 min

(for reference)
When the engine is stalled, heat is generated
inside the torque converter. Therefore, never run
the engine for 30 seconds or longer, and never
run the engine if the oil temperature is 90°C
(194°F) or above.
The torque converter generates maximum
torque at this time. Therefore, be careful to avoid
sudden movement of the vehicle.
