INSTRUCTIONS FOR 3 KW GENERATOR SET
Instructions for the engine portion are generally the same as for
the propulsion unit WlOtwo.
The differences will be described in the
following pages.
BREAKING IN
Service life of your generator is dependent upon how the engine is
operated and serviced during the initial 10 hours of operation!
Your new engine needs at least 10 hours of conditioning operation
for breaking each moving part in and maximizing performance and life
of engine.
Perform this conditioning carefully, bearing the following
points in mind:
1.

2.
Do not ever attempt to BREAK IN your generator set by running at
NO LOAD.
3.
Immediately on starting
the set,
add approximately 25% load to
cause a fast warm up.
4.
For the first 10 hours of operation, run between 20 and 60 percent
load.
5.
After 10 hours, you may load as needed, except that:
6.
You must avoid overload at all times.
Overload is signalled by
smoky exhaust and/or a reduction in speed and voltage.
Explanation:
"Breaking in" a new engine is basically a seating of the piston rings
to the cylinder walls.
This is not accomplished by long per iods of
running idle, nor by early running under full load.
Idle running may glaze the cylinder walls causing oil consumption and
smoky operation.
Excessive loads may score cylinder walls with simi-
lar results.
As indicated above, use a short warm up period under moderate load for
the
first
ten hours of operation.
For the next forty hours,
use
approximately 70% load.
This kind of careful operation will result in
best results from your engine.
