Starting

Before starting

WARNING! Before starting the engine make sure that neither people, nor tools, are in contact with
moving parts of the engine. Notify the people in the vicinity of the engine when starting it.
WARNING! Make sure that you know how to stop the engine before you start it (in case of emergency).
If you are starting the engine for the first time, have someone stand-by at the emergency stop lever to
stop the engine in case abnormal noise occurs during start up. Block air intake in case of stop lever
malfunction, this has to be prepared in advance.
WARNING! Make sure that the manual speed control knob is locked in neutral position before starting
the engine (refer to page 26 of this manual).
IMPORTANT! If the starter motor has been engaged for the maximum time (30 seconds), it must be
allowed to cool down for at least one minute before a new attempt is made at starting.

Warming-up

WARNING! Do not conduct warm-up operation for an extended period of time. Prolonged warm-up
operation causes carbon buildup in the cylinders that leads to inperfect combustion.
* Operate at low idle speed for 5 to 10 minutes to warm up the engine.
* The oil pressure will be 0.20 to 0.29 MPa [28 to 43 psi] after the warm-up run. If the engine speed is increased
immediately after start-up, the oil pressure, due to cold lubrication oil and therefore higher viscosity, will ex-
ceed the normal level - 0.49 to 0.64 MPa [71 to 92 psi] (at rated speed) but it will normalize with increasing oil
temperature.
* If the Lubrication oil pressure does not increase when you have started the engine, immediately stop the engi-
ne and do not restart until the problem has been fixed.
* Make sure that the cooling water flow is sufficient.
* Make sure there is enough fuel aboard the vessel for the planned duration of operation.
