MAINTENANCE
Using a Torx screwdriver, remove the screw from the
rocker arm cover. Remove the cover and set aside.
Position camshaft by pulling the starter grip and rope just
until the deep hole in the camshaft gear is located at the
6 o’clock position as shown.
Place the feeler gauge under each rocker arm and measure
the gap. The gap should be between .006 in. (0.15 mm)
and .008 in. (0.20 mm) for both rocker arms.
NOTE: Use a standard automotive feeler gauge. The
.006 in. (0.15 mm) feeler gauge should slide between
the rocker arm and valve stem with a slight amount of
resistance but without binding. The 0.008 in. (0.20 mm)
feeler gage should not slide between the rocker arms and
the cam lobes — it should be held tight.
If the valve clearance is not between .006 in. (0.15 mm)
and .008 in. (0.20 mm), the clearance should be adjusted
as follows:
• While holding a wrench on the flats of the adjusting nut
with one hand, loosen the retaining nut with a second
wrench as shown. Take care not to loosen the stud.
• Rotate the adjusting nut until it touches the feeler gauge.
Once the gap setting is correct, hold the wrench on
the flats of the adjusting nut and retighten the retaining
nut securely.
Adjust the second rocker arm, if necessary.
Replace the rocker arm cover and screw; tighten securely.
Replace the top engine cover and screw; tighten securely.
WARNING:
Ensure all engine cover and all engine parts are
completely and properly reassembled before starting
engine. Failure to correctly reassemble engine could
result in serious injury or property damage.
STORING THE PRODUCT
We recommend that the unit be kept in a horizontal position
when stored.
Clean all foreign material from the product. Store idle unit
indoors in a dry, well-ventilated area that is inaccessible
to children. Keep away from corrosive agents such as
garden chemicals and de-icing salts.
If storing the product vertically, do so with the engine up
to avoid hydraulically locking the engine due to lubricant
entering the combustion chamber.
NOTE: If the engine/starter rope becomes locked after
storage, place the unit flat on the ground in the upright
position to allow the engine lubricant to slowly migrate
back into the engine’s oil reservoir.
Abide by all ISO and local regulations for the safe storage
and handling of gasoline.
When storing 1 month or longer:
Drain all fuel from tank into a container approved for
gasoline. Run engine until it stops.
HIGH ALTITUDE ENGINE OPERATION
Your engine is configured for operation below 2000 feet
altitude at the factory. Your engine must be reconfigured for
operation above 2000 feet altitude. Operating the engine
with the wrong engine configuration at a given altitude may
increase its emissions, decrease fuel efficiency, degrade per-
formance and cause irreversible damage. Engines configured
for high altitude operation cannot be operated in standard
altitude conditions. A qualified service center should ensure
that your engine is properly configured for your location.
