3. OPERATION
EN
(6) When the key switch is turned, the
engine will begin cranking. Contin-
ue cranking for about 5 seconds,
and check for abnormal noise dur-
ing that time. (If you remove your
hand from the stop knob or stop
button while cranking, the engine
will start.)
3.2.6 Check and Re-supply Lubri-
cating Oil and Cooling Water
When engine oil, clutch oil, or cooling wa-
ter is supplied for the first time or when
they must be replaced, conduct a trial op-
eration of the engine for about 5 minutes
and check the quantity of lubricating oil
and cooling water. The trial engine opera-
tion will send the lubricating oil and cooling
water to the passages, so the lubricating
oil and cooling water levels will drop.
Check and re-supply as necessary.
(1) Supplying engine lubricating oil
(See 3.2.2). Approximately 10 min-
utes after stopping the engine, re-
move the oil dipstick and check the
oil level. Add oil if the level is too
low.
(2) Supplying marine gear lubricating
oil (See 3.2.3).
(3) Supplying cooling water (See
3.2.4).
3.3 Operating your engine
To prevent exhaust gas poisoning, en-
sure good ventilation during operation.
Install ventilation windows, ports or
ventilators in the engine room. Never
touch or allow your clothes to touch the
moving parts of the engine during oper-
ation. If the front drive shaft, V-belt,
propeller shaft, etc. catches your body
or clothes, serious injury may result.
Check that no tools, cloth, etc. are left
on or around the engine.
The engine is very hot during operation
and immediately after stopping, espe-
cially the exhaust manifold and the ex-
haust pipe. Avoid burns! Never touch
or allow your clothes to touch any part
of the engine.
3.3.1 Daily Start Up Inspection
Before starting the engine, make it a daily
rule to conduct the following inspections:
(1) Visual Checks
Check for the following:
1. Lubricating oil leakage from the en-
gine
2. Fuel oil leakage from the fuel system
3. Water leakage from the cooling water
system
4. Damage to parts
5. Loosening or loss of bolts
If any problem is found, do not operate
the engine before completing repairs.
Never open the cap of the
coolant tank while the en-
gine is still hot. Steam
and hot water will spurt
out and burn you serious-
ly. Wait until the tempera-
ture of the coolant tank
has dropped, wrap a
cloth around the filler cap
and loosen the cap slow-
ly. After inspection, refas-
ten the cap firmly.
