The pressure in the air tank may override the manual
shutdown condition of the pilot valve: The regulator
valve, which is set to 10 psi, will signal the compressor to
operate, running the engine at full throttle (regardless of
the position of the pilot valve switch) if the pressure in the
tank is below 10 psi. This action builds the pressure in
the tank until it is enough to satisfy the regulator valve
(with a signal of at least 10 psi), and then the compressor
will shut down.
For a visual aid to understanding the operation of the
pilot valve, refer also to
Section A.8 in the Appendix .
Although the pressure cut-in and cut-out pressures are
pre-set at the factory, they may be manually adjusted.
For procedure on pressure control switch adjustment,
see
Section 6.5.5 .
2.3 ENGINE
See Figure 2-6 . The 200 Series All-In-One Power
System utilizes the 25 HP EFI Kohler
®
gasoline engine,
which features electronic fuel-injection, air-cooled,
electric start with a fuel economy improvement up to
27%. It powers both the compressor unit and generators
simultaneously. The engine has a full flow oil filter, while
also offering re-borable and replaceable cylinders,
grindable crankshaft, replaceable valve guides and
seats, and heavy-duty engine bearings.
The engine is preset to a fixed speed. For information on
speed control setting, consult
Section 6.5.6, Adjusting
the Engine Speed .
The compressor and generator are driven by the engine
via the use of two drive belt types. The compressor
NOTE
It is recommended that the operator shut
the air valve off when a project is
completed. This will prevent the pressure
in the tank from leaking down, and
causing unnecessary engine speed.
NOTE
Do not tamper with the governor setting
to increase the maximum engine speed.
Overspeed is hazardous and will void the
engine warranty. The maximum allowable
high idle speed no load for these engines
is 3600 RPM.
NOTE
When purchasing air tools or planning a
project, the rated capacity of the
compressor (24 CFM up to 175 psi) will
need to be taken into consideration.
