LOCATION
Selecting the proper location can significantly increase
performance, reliability and life of the unit.
◆ For best results locate the unit in an environment that is
clean and dry. Dust and dirt in the unit retain moisture and
increase wear of moving parts.
◆ There are mounting holes in the bottom of the open frame
models to permanently mount the unit if desired. The bolt
pattern is 20 inch x 26 inch and will accept 1/2 inch bolts.
The wheels (if present) must be removed.
◆ Store electrodes in a clean, dry location with low humidity to
preserve the flux coating.
LUBRICATION
CHECK ENGINE AND PUMP OIL LEVELS
BEFORE OPERATING! Follow lubrication
instructions before operating compressor.
1. Oil is NOT mixed with the gasoline, however adequate
oil supply is necessary for proper engine lubrication.
Refer to the Engine Manual for SAE, API and fill quantity
specifications.
2. Remove pump breather and fill pump with 8.5 oz. of oil. Use
full synthetic motor oil like Mobil 1
®
10W-30. Do not use
regular automotive oil such as 10W-30. Additives in regular
oil can cause valve deposits and reduce pump life. For
pumps with an oil sight glass, oil level can be monitored and
maintained as shown in Figure 1.
GROUNDING
1. Use the ground terminal and wing nut on the frame to
connect the unit to a suitable ground source. Securely fasten
the end terminal of the ground wire to the ground terminal
on the frame. Tighten the washer and wing nut on top of the
ground wire end terminal.
2. The ground wire should be made of #8 gauge wire. Do
not use wire with a higher gauge number. Higher gauge
numbers indicate thinner wire, which may not provide an
adequate ground path.
3. The other end of the ground wire must be securely fastened
to an approved ground source.
The following are ground sources approved by the National
Electric Code. Other ground sources may be acceptable.
Refer to the National Electric Code and local regulations for
further ground source information. If not sure of regulations
or procedures, obtain assistance from a qualified (licensed or
certified) electrical technician.
a. An underground water pipe at least ten feet in length
b. A non-corrosive underground pipe at least eight feet in
length and 3/4 inch diameter
c. A steel or iron underground rod at least eight feet in
length and 5/8 inch diameter
d. A non-ferrous rod at least eight feet in length, 1/2 inch in
diameter, and approved for grounding purposes
Any rod or pipe used for grounding must be driven to eight feet
deep or buried in the deepest possible trench.
STARTING
1. Remove all electrical loads from the unit.
2. Set compressor switch to OFF position.
3. Move fuel shut-off lever as far as possible to the right to
enable fuel flow.
4. Set the engine switch to the RUN position.
5. For a cool engine, pull the choke knob out.
6. Push and hold the START switch until the engine starts,
then release.
7. After each start up, allow the engine to run for 2 to 3
minutes with no load.
8. As the engine warms up and stabilizes, adjust the choke
knob in fully.
Engine speed is preset to provide proper output
voltage. Never attempt to modify or adjust
engine speed or output voltage.
ENGINE BREAK-IN
After initial start-up, the engine should be broken in according
to the manufacturer’s instructions. Refer to the engine manual
for the proper break-in procedure.
COMPRESSOR BREAK-IN
Open the drain valves in the end of the two tanks. Turn the
compressor switch to ON and allow the pump to run without a
load for 30 minutes. After 30 minutes, close the drain petcocks
and pressure will begin to build in the tanks.
SHUT-OFF
1. Shut off and remove all electrical load devices from the unit
2. Set compressor switch to OFF position.
3. Allow the engine to run for
2-3 minutes with no electrical loads.
4. Set the engine switch to the OFF position.
5. Verify that the unit has completely stopped.
6. Close the fuel supply valve.
7. Allow the unit to cool before installing any covers or storing
unit.
