Owner’s Manual for Portable Generator
4.9 — Battery Replacement
(if applicable)
When the battery will no longer accept a charge, replace-
ment is necessary. The battery is needed to use the elec-
tric starter.
NOTE: The battery shipped with the generator has
been fully charged. A battery may lose some of its
charge when not in use for prolonged periods of
time. If the battery is unable to crank the engine, plug
in the 12V charger included in the accessory box
(see the Charging the Battery section). RUNNING
THE GENERATOR DOES NOT CHARGE THE BAT-
TERY.
To replace the battery, see Figure 4-6.
1.
Disconnect and remove the battery mounting hard-
ware (8mm) and BLACK wire from the battery’s
NEGATIVE (-) terminal.
2.
Move the red protective boot and disconnect the bat-
tery mounting hardware (8 mm) and RED wire from
the battery’s POSITIVE (+) terminal.
3.
Remove the two screws and bracket from the battery
tray. Remove the battery.
4.
Place the new battery in the tray. Secure with the
bracket and two mounting screws. Tighten screws
securely.
5.
Reconnecting the RED wire to the POSITIVE (+) ter-
minal and the BLACK wire to the NEGATIVE (-) ter-
minal.

NOTE: Your generator can still be operated using the
recoil starter.
4.10 — Check/Adjust Valve Clearance
IMPORTANT:
If uncomfortable performing this procedure
or the proper tools are not available, take the generator
to the nearest service center to have the valve clearance
adjusted. This procedure is a very important step to
ensure maximum engine service life.
4.10.1— Check Valve Clearance
1.
Verify that engine is at ambient air temperature.
2.
Remove spark plug cable and spark plug. See
Subsection 4.8 — Clean/Gap/Replace Spark Plug.
3.
Remove six screws to release valve cover.
4.
Move piston to Top Dead Center (TDC) of com-
pression stroke (both valves closed). Proceed as
follows:
a. Slowly pull handle of recoil starter while watch-
ing piston through the spark plug hole.
b. The piston moves up and down and reaches
TDC at its highest point of travel.
NOTE: Intake rocker arm is on the carburetor side,
exhaust rocker arm is on the muffler side.
5.
Insert a 0.006 in. (0.15 mm) feeler gauge between
the intake rocker arm and valve stem. The clear-
ance is correct if a slight drag is felt when sliding
the feeler gauge back and forth. Verify that clear-
ance is within the following specification:
•
Intake: 0.006 in. ± 0.0008 in. (0.15 ± 0.02mm)
6.
Insert a 0.008 in. (0.20 mm) feeler gauge between
the exhaust rocker arm and valve stem. The clear-
ance is correct if a slight drag is felt when sliding
the feeler gauge back and forth. Verify that clear-
ance is within the following specification:
•
Exhaust: 0.008 in. ± 0.0008 in. (0.20 ± 0.02mm)
7.
Proceed as follows:
a. If valve clearance adjustment is required, see
Subsection 4.10.2— Adjust Valve Clearance.
b. If valve clearance is within specification, see
steps 5-8 under Subsection 4.10.2— Adjust
Valve Clearance.
4.10.2— Adjust Valve Clearance
1.
Loosen rocker arm jam nut.
2.
Use a wrench to turn the pivot ball stud, while also
using feeler gauge to check clearance between
rocker arm and valve stem.
NOTE: Hold the rocker arm jam nut in place as the
pivot ball stud is turned.
