Assembly
(continued)
Hex Wrench
Tighten the assembly
(blade not shown for
clarity)
CAUTION!
Install the blade so its printed sur-
face is visible to the operator when
the brushcutter is in the normal
operating position.
The unit should now be
completely assembled and
ready for use with a blade.
IMPORTANT!
Discard blades that are bent, warped,
cracked, broken or damaged in any way.
Use a sharp blade. A dull blade is more
likely to snag and thrust.
Install the bolt guard and then the
5.
blade retaining bolt. Using the com-
bination spark plug wrench/screw-
driver, tighten the bolt firmly in a
counter-clockwise direction.
Remove the hex wrench.
6.
Using the combination spark plug wrench/
screwdriver, tighten the bolt firmly in a
counter-clockwise direction.
WARNING!
Alternative fuels, such as E15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting Shindaiwa
requirements are NOT approved for use in Shindaiwa gasoline engines. Use of alternative fuels may cause
performance problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including,
but not limited to, improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel
lines, gaskets, carburetors and other engine components.
Fuel Requirements
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain
up to 10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (wood
alcohol) is
NOT approved.
2 Stroke Mixture Oil - A 2-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD standards
must be used. Shindaiwa One
TM
2-Stroke Oil is strongly recommended as it meets this standard and is specifically
formulated for use in all Shindaiwa 2-stroke engines. Engine problems due to inadequate lubrication caused by fail-
ure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD certified oil will void the engine warranty.
Mixing Fuel
For increased engine protection, Shindaiwa recommends using Shindaiwa Red Armor
TM
engine oil to protect the engine from
harmful carbon build up, maintain engine performance, and increase engine life. Shindaiwa Red Armor
TM
engine oil exceeds
ISO-L-EGD and J.A.S.O. M345/FD performance requirements.
IMPORTANT!
Shindaiwa One
TM
2-Stroke oil or Red Armor
TM
engine oil may be mixed at 50:1
ratio for application in all Shindaiwa engines sold in the past, regardless of ratio
specified in those manuals.
IMPORTANT!
Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30)
days, ninety (90) days when a fuel stabilizer is added. Use of unmixed, improp-
erly mixed, or stale fuel, may cause hard starting, poor performance, or severe
engine damage and void the product warranty. Read and follow instructions in
the Long Term Storage section of this manual.
