WARMING UP
When starting the engine allow it to warm up to operating temperature by allowing it to idle 5-10
minutes to ensure full lubrication and operating temperature.
Failure to do so can shorten engine life substantially.
► WARMING UP IN COLD WEATHER
Cold weather will change the viscosity of the oil, resulting in a reduced oil pumping capacity, which
can cause damage to the engine if it is not warmed up correctly.
It also causes problems with the hydraulic system and the synchromesh in the transmission.
Correct times for warming up are:
Temperature Time for warming up
Above 50°F
5~10 min.
50°F~ 32°F
10~20 min.
32°F~14°F
20~30 min.
14°F~-4°F
30~40 min.
Below –4°F
Over 40 min.
Important
Ensure the handbrake (Foot brake) is on during the warming period.
Failure to warm up correctly can result in problems.
When the engine is warm, push down the clutch and engage the main and auxiliary gear levers to the
required position.
Push down on the brake pedals and release the handbrake.
Increase the engine revolutions and let out the clutch smoothly.
Only change gears with the main gear lever while moving and ensure that this is done with the full use of
the clutch.
STORING ENGINE IN OPERABLE CONDITION FOR 3 MONTHS OR MORE
53
When the engine is not operated during a storage period of three months or more, internal engine parts
can rust and lose oil film. As a result, the engine can seize when it is started after storage.
To prevent such a rust, the engine must be operated periodically during storage.
