(1) Dead battery

(3) Helper battery
IMPORTANT :
• This tractor has a 12 volt negative (-) ground
starting system.
• Use only the same voltage for jump starting.
• Use of a higher voltage source on tractor’s
electrical system could result in severe
damage to tractor's electrical system.
Use only matching voltage source when
“Jump starting” a low or dead battery
condition.
• Do not operate the tractor with the battery
cable disconnected from the battery.
• Do not operate the tractor without the
battery mounted.
• Do not operate the tractor with the battery
dead. Charge the battery fully before
operating the tractor.
Otherwise, the tractor might malfunction.
ENGINE OPERATION
1. Key switch
The starter switch has 4 positions.
“OFF” (engine-stop)
“ACC” (electrical power-accessories)
“ON” (engine-run)
“START” (engine-start)
NOTE :
Regarding ACC:
• All the accessories can be used while the
engine is stopped.
• Do not leave the key at “ACC” position. The
battery will be quickly discharged. Turn it back
to “OFF” after use.
2. Engine power boost
In any of the following conditions, the engine output is
boosted for higher working efficiency. For work
requiring no high output, on the other hand, the
machine runs at standard output level with fuel
economy in mind.
Trailer towing work
When the travelling speed rises above 20 km/h (12.4
mph), the engine output boosts itself. When it drops
below 18 km/h (11.2 mph), the power boost turns itself
off.
PTO operation
When the PTO clutch is engaged, the engine output
boosts itself.
3. Rev-limiter control setting
When the rev-limiter control is used to restrict the
maximum engine speed, the engine speed will not
exceed the set speed even when the hand throttle or
foot throttle is operated. This can prevent machine
trouble caused by incorrect operation.
Setting the speed (Standard model)
The setting can be made both when the engine is
running and when it is stopped.
