OPERATION
Ethanol (ethyl or grain alcohol) 10% by volume. You
may use gasoline containing up to 10% ethanol by volume.
Gasoline containing ethanol may be marketed under the
name “Gasohol.” Do not use E85 fuel.
MTBE (methyl tertiary butyl ether) 15% by volume. You
may use gasoline containing up to 15% MTBE by volume.
Methanol (methyl or wood alcohol) 5% by volume. You
may use gasoline containing up to 5% methanol by volume
as long as it also contains cosolvents and corrosion inhibi-
tors to protect the fuel system. Gasoline containing more
than 5% methanol by volume may cause starting and/or
performance problems. It may also damage metal, rubber,
and plastic parts of the product or your fuel system.
If you notice any undesirable operating symptoms, try anoth-
er service station or switch to another brand of gasoline.
NOTE: Fuel system damage or performance problems re-
sulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates stated previously are
not covered under warranty.
CAUTION:
Attempting to start the engine before it has been properly
filled with lubricant will result in equipment failure.
ADDING/CHECKING ENGINE LUBRICANT
See Figure 7.
Engine lubricant has a major influence on engine perfor-
mance and service life. For general, all-temperature use,
SAE 10W-30 is recommended. Always use a 4-stroke mo-
tor lubricant that meets or exceeds the requirements for
API service classification SJ. Check lubricant level before
each use.
NOTE: Non-detergent or 2-stroke engine lubricants will
damage the engine and should not be used.
To add engine lubricant:
Remove the cap and seal from lubricant bottle pro-
vided.
Unscrew the oil cap/dipstick and remove.
Using funnel provided, add entire bottle of engine lubricant
through oil fill hole.
Reinstall the oil cap/dipstick and secure.
To check engine lubricant level:
Set engine on a flat surface.
Wipe dipstick clean and re-seat in hole; do not rethread.
Remove dipstick again and check lubricant level. Lubricant
level should fall within the hatched area on the dipstick.
If level is low, add engine lubricant until the fluid level rises
to the upper portion of the hatched area on the dipstick.
Replace and secure the oil cap/dipstick.
CAUTION:
Do not overfill. Overfilling the crankcase may cause
excessive smoke and engine damage.
OPERATING THE TRIMMER
See Figure 8.
WARNING:
Always position the unit on the operator’s right side. The
use of the unit on the operator’s left side will expose
the user to hot surfaces and can result in possible burn
injury.
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the trimmer with your right hand on the rear handle
and your left hand on the front handle. Keep a firm grip with
both hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Cut tall grass from the top down. This will prevent grass from
wrapping around the shaft housing and string head which
could cause damage from overheating. If grass becomes
wrapped around the string head, STOP THE ENGINE, dis-
connect the spark plug wire, and remove the grass.
WARNING:
Always hold the string trimmer away from the body keep-
ing clearance between the body and the product. Any
contact with the housing or string trimmer cutting head can
result in burns and/or other serious personal injury.
TO ADVANCE THE CUTTING LINE (REEL EASY
STRING HEAD)
Line advance is controlled by tapping the string head on
grass while running engine at full throttle.
Run engine at full throttle.
Tap the knob on ground to advance line. The line advances
each time the knob is tapped. Do not hold the knob on
the ground.
NOTE: The line trimming cut-off blade on the grass deflector
will cut the line to the correct length.
NOTE: If the line is worn too short you may not be able to
advance the line by tapping it on the ground. If so, stop the
engine and manually advance the line.
