ENGINE OPERATION
NOTICE
Do not place engine under FULL LOAD at FULL SPEED
IMMEDIATELY after starting. ALWAYS allow the engine to fully
circulate lubricate and warm up gradually before operating at full
speed and full load.
Operate engine at top rated speed when maximum power is needed
for the load. Operation of the engine below top rated speed can
occur during gear shifting due to the difference of ratios between
transmission gears, but engine operation MUST NOT be sustained
more than 30 seconds at full throttle below top rated speed.
NEVER idle the engine more than 5 minutes at a time; shut it off.
If any gauge operates outwith its normal operating range or a
warning light illuminates, shut engine down immediately and re-
port to service or maintenance personnel.
NOTICE
Never start the engine indoors unless proper exhaust ventilation is
provided to remove deadly exhaust gases. Once the engine is
running, move the machine outdoors as soon as possible. Exhaust
gases are hazardous and can cause unconsciousness and death.
Operating the engine beyond high idle speed can cause severe
engine damage. The engine speed must not exceed 2 400 rev/min
under any circumstances. When descending a steep grade, use a
combination of transmission gears, retarder and service brakes to
control the vehicle and engine speed.
