Air Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have an authorized service
dealer clean the cooling system (A) per recommended
intervals (see Maintenance Schedule in beginning of
Maintenance section). Equally important is to keep top of
engine free from debris. See Clean Debris.
Check Valve Clearance
Regular valve clearance check and adjustment will improve
performance and extend engine life. This procedure cannot
be done without partial engine disassembly and the use of
special tools. For this reason we recommend that you have
an authorized service dealer check and adjust valve clearance
at recommended intervals (see Maintenance Schedule in the
Maintenance section).
Carburetor Adjustment
The carburetor on this engine is low emission. It is equipped
with a non-adjustable idle mixture valve. Top speed has been
set at the factory. If adjustment is required, see an
authorized service dealer.
A
CAUTION
Excessively high operating speeds increase risk of injury
and damage to generator.
Excessively low speeds impose a heavy load.
• DO NOT tamper with governed speed. Generator supplies
correct rated frequency and voltage when running at governed
speed.
• DO NOT modify generator in any way.
