ENGINE OPERATION
Engine exhaust gas caution (carbon monoxide)
CHECK BEFORE OPERATION
Engine oil level
Place the engine or the machine on a level surface.
Remove the dipstick, wipe it with a cloth. Insert it fully and take it out
gently again.
Check the oil level against the marks on the dipstick. The oil level must
be between the “H” level mark and the “L” level mark as illustrated.
Fig. 3
Also check the sample oil on the dipstick for contamination and
viscosity.
Take care not to add too much engine oil.
Oil can be poured either through the oil filler at the front of the cylinder
head cover or through the oil filler on the right side of the timing gear
case.
A certain period of time is required before the engine oil completely
flows down from the oil filler to the crankcase. Wait at least ten minutes
before checking the oil level.
Fan and belt check
The engine is fitted with an automatic belt tensioner
Check the fan belt for tension and abnormalities.
A loose belt will cause belt slippage which may result in a damaged
belt, abnormal noise, poor battery charging and engine overheating.

Use of genuine Doosan fan belt
Always use genuine Doosan fan belts as they provide high driving
ability and long operating durability. Use of non-Doosan fan belts could
result in premature belt wear or belt elongation leading to engine
overheating or excessive belt noise.
Coolant level check
Check and ensure that the level is correct.
Add coolant mixed to the correct ratio: 50/50 ethylene glycol/water.
Radiator cap condition
After the replenishment of the coolant, install the radiator filler cap.
Make sure the cap is securely installed.
Crankcase breather
Check and clean the breather tube daily during cold weather.
CAUTION: Do not breathe exhaust gas because it contains
carbon monoxide, which by itself has no colour or odour.
Carbon monoxide is a dangerous gas. It can cause
unconsciousness and can be lethal.
Do not run the engine in confined areas (such as garages or next
to a building). Keep the exhaust pipe clear of snow and other
material to help reduce the buildup of exhaust gases under the
equipment. This is particularly important when parked in
blizzard conditions.
CAUTION: For safety reasons, conduct the inspection with the
engine stopped.
NOTE: Take care to avoid engine oil being splashed on the fan
drive belt because it causes belt slippage or slackness.
CAUTION: When adding oil, take care not to spill it. If you spill
oil on the engine or equipment, wipe it off properly, to prevent
the risk of fire and personal injury and/or equipment damage.
CAUTION: When removing the radiator filler cap, while the
engine is still hot, cover the cap with cloth, then turn it slowly to
gradually release the internal steam pressure. this will prevent
anyone from being scalded by hot steam spurting out from the
filler neck.
