BASIC OPERATION
This low oil warning system will automatically stop the
engine before the oil level reaches an operational danger
point. This feature is designed to prevent costly repairs
and downtime.
The OILGARD system uses a float in the engine crankcase
to sense the oil level. If a low oil level condition should
occur during operation, the float will ground out the
magneto impulse, “killing” the engine. In addition, there is
an indicator light mounted on the engine shroud near the
recoil starter. This light will blink on and off to indicate a low
oil level condition when you are attempting to start the unit.
To get the engine started, you must add the required
amount of oil to the engine crankcase.
Use of the OILGARD system on applications that are
subject to shock, bumping or severe angles of operation (in
excess of 15 degrees) should be avoided. This is
especially true if an unexpected shutdown would cause a
safety hazard or serious inconvenience for the operator.
Honda powered generators - These engine generator
sets come equipped standard with the Honda Oil Alert
System.
The Oil Alert system is designed to prevent damage
caused by an insufficient amount of oil in the crankcase.
Before the oil level in the crankcase can fall below a safe
limit, the Oil Alert system will automatically shut down the
engine (the engine switch will remain in the ON position).
If the Oil Alert system shuts down the engine, the Oil Alert
lamp will flash when you attempt to start the engine and it
will not run. If this occurs, check the engine oil level.
LP/NG FUEL INSTALLATION
The information in this instruction is offered to assist you in
providing the proper vapor fuel supply for your engine. This
information is only provided to advise you of the engine’s
requirements and the decisions you must make. In no case
should this information be interpreted to conflict with any
local, state or national code. If in doubt, always follow local
codes.
DANGER: FIRE - PERSONAL INJURY -
All fuel lines must be installed by a qualified fuel
supplier.
OPERATING LOCATION
The engine-generator models covered in this manual were
designed for portable use. DO NOT INSTALL OR OPERATE
THESE UNITS INDOORS. The unit should be stored in a dry
location. During a power outage move the unit outdoors to
a flat dry location such as a driveway, concrete pad or
sidewalk for use. We recommend installing the optional
dolly kit or equivalent for ease of handling.
The fuel source should be as close as possible to the
outdoor operating location. This will reduce the installation
cost of fuel runs. Connect the fuel supply line to the inlet of
the fuel demand regulator on the unit using a locally
approved flexible fuel line (see table for recommended line
size). The pressure supplied to the demand regulator
must be FOUR TO SIX OUNCES or 7 to 11 INCHES W.C.
(water column). The primary regulator at the fuel supply
must be capable of delivering the proper volume of fuel at
this pressure.
Have your local fuel supplier install a protected fuel
connection at the outside operating location. He should
also install a lockable fuel shutoff valve at the connection
point. Have your fuel supplier permanently install a
flexible fuel line to the demand regulator on the engine
generator set.
INSTALLING THE FUEL LINE
DANGER: PERSONAL INJURY
Units that are intended to be run unattended MUST
have an electric fuel solenoid installed. This solenoid
MUST be wired to AUTOMATICALLY turn off the fuel
whenever the engine stops. See page 9 for additional
information.
Unit location will determine the size of fuel line that is
required to supply the engine with a constant fuel
pressure. Refer to the tables below for fuel line size, and
recommended tank size. For distances of 100 feet and
over, a two regulator fuel system is recommended. This
system consisting of a primary 10-15# regulator at the
tank and a 6 ounce secondary regulator installed about
10 feet from the generator. You need to run a 3/4 inch line
or larger from the secondary regulator to the engine-
generator set. When a two (2) regulator fuel system is
used, a fuel line size of 3/8 inch is generally adequate for
distances up to 300 feet. The line size from the table
below applies to the distance from the second regulator
to the demand regulator. A positive fuel shut-off device
must be installed in the fuel line close to the engine
generator set. This may be either a lockable manual
shut-off valve available from your local fuel installer, or a
12 volt DC fuel solenoid valve. This optional 12 volt DC
valve is available through your local Winco dealer, see
page 9 for additional information.
The fuel line used to connect the supply line to the
demand regulator must be a locally approved flexible fuel
line. Products used will vary in different regions
depending on availability and local codes. Consult with
your local fuel supplier to insure complete compliance
with ALL codes.
1. Remove the pipe plug from the demand regulator.
2. Connect the flex fuel line to the demand regulator.
DANGER: PERSONAL INJURY
Do not use galvanized pipe in the fuel line runs. The
galvanized coating will become eroded and flake off,
causing possible obstruction or damage to the
regulator or fuel valve. The obstruction could cause an
inoperative engine or an explosive fuel leak.
Size of pipe required for generators operating on natural
gas/LP gas.
Length of Fuel Line* Fuel Line Size
less than 25 feet 3/4 inch black pipe
25 to 100 feet 1 inch black pipe
over 100 feet not recommended
*allow an additional 3 feet for each standard elbow. Do
not use ‘street ells’ (restrictive)
