Adjust Engine Speed - Yanmar L48N Operation Manual

ADJUST ENGINE SPEED

CAUTION
New Engine Break In:
• On the initial engine start-up, allow the
engine to idle for approximately 15
minutes while you check for proper
engine oil pressure, diesel fuel leaks,
engine oil leaks, and for proper
operation of the indicators and / or
gauges.
• During the first hour of operation, vary
the engine speed and the load on the
engine. Short periods of maximum
engine speed and load are desirable.
Avoid prolonged operation at
minimum or maximum engine speeds
and loads for the next 100 hours.
• During the break-in period, carefully
observe the engine oil pressure and
engine temperature.
• During the break-in period, check the
engine oil levels frequently.
Use the engine speed control to adjust the engine
speed for the task that will be performed.
Several types of engine speed controls are used
in L-N engine applications. The following
procedures are for three typical applications.
Refer to the operating instructions for the driven
machine.
1. If your engine speed control is similar to
Figure 14 slide the engine speed control
lever (Figure 14, (1)) in the direction shown to
adjust the engine speed.
Note: This is a friction adjustment. If the
speed control will not maintain a given
speed, tightening the nut will increase
the friction on the speed control lever.

2. If your engine speed control is similar to
Figure 15 slide the engine speed control
lever (Figure 15, (1)) in the direction shown to
adjust the engine speed.
Note: This type of speed control, typically
used on a generator set, has only one
speed setting. When you move the
lever to the right, it clicks into the RUN
position. The speed control lever is
spring-loaded so when you push down
on the STOP button, the speed control
lever moves back to the shut-off
0000011en
position. There is no idle position or
intermediate speeds.
