OIL:
This Edger/Trimmer was shipped with a 20
ounce container of SAE30 motor oil. This
oil must be added to the engine before
operating. Remove the oil fill cap/dipstick
to fill the crankcase. DO NOT OVERFILL.
NOTE:
Engine may already contain some
residual oil. Check frequently
the crankcase.
when filling
OIL RECOMMENDATIONS
Only use high quality detergent oil rated
with API service classification SG. Select
the oil's SAE viscosity grade according to
your expected operating temperature.
A{though mu{ti-viscosity oils (5W30, 10W30,
etc.) improve starting in cold weather, these
multi-viscosity oils will result in increased oil
consumption when used above 32°F.
Check your engine oil level more frequently
to avoid possible engine damage from
running low on oil.

TO ADJUST
CARBURETOR
The carburetor
shown below has been pre-
set at the factory and readjustment should
not be necessary. However, if the carburetor does need to be adjusted, proceed as
follows:
• Start the engine and let it warm up.
• Set the throttle control to FAST. Adjust
the high speed adjusting screw in until
the engine speed or sound alters. Adjust
the screw out until the engine speed
sound alters. Note the difference between
the two limits and set the screw in the
middle of the range.
• If the engine tends to stall under load or
not accelerate from low speed to high
speed properly, adjust the high speed
screw out in 1/8 turn in_:rements until the
problem is resolved.
• Let the engine run undisturbed for 30
seconds between each setting to allow
the engine to react to the previous
adjustments.
IMPORTANT:
Never tamper the engine
governor, which is factory set for proper
engine speed. Overspeeding the engine
above the factory high speed setting can
be dangerous. If you think the enginegoverned high speed needs adjusting,
