Carrier and the Tool Assembly on
a clean, flat surface so that both assemblies fit end to end. The M242
assembly should be facing up, and the
tool assembly should be positioned
with the locking hole in the tube end
facing up. See Figure 4.

loosen the coupler screw knob. The
spring-loaded coupler protector
should pop up.
2. Press down on the latch with your
finger or thumb. This releases the
coupler lock. See Figure 6.
3. Pull the tool assembly out of the
coupler.
CAUTION!
Keep the open ends of the tubes
clean and free of debris!
2. Slip off the protective covers from the
ends of both tubes, and loosen the
coupler screw knob.
3. Insert the upper tube assembly into
the coupler, with the tool decal facing
up, until the line of the decal is flush
with the end of the coupler. Twist the
tool back and forth until you are sure
it snaps in place by the coupler latch.
See Figure 4.
4. When the two tube halves are locked
together, press down on the springloaded latch protector and tighten the
coupler screw knob. See Figure 5.

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 OneTM 2-Stroke Oil is strongly recommended as it meets this standard and is specically
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 certied oil will void the engine warranty.
Mixing Fuel
For increased engine protection, Shindaiwa recommends using Shindaiwa Red ArmorTM engine oil to protect the
engine from harmful carbon build up, maintain engine performance, and increase engine life. Shindaiwa Red ArmorTM
engine oil exceeds ISO-L-EGD and J.A.S.O. M345/FD performance requirements.
IMPORTANT!
Shindaiwa One
TM
2-Stroke oil or Red ArmorTM engine oil may be mixed at 50:1
ratio for application in all Shindaiwa engines sold in the past, regardless of ratio
specied 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, improperly 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.
Examples of 50:1 mixing quantities
Handling Fuel
DANGER
Fuel is VERY ammable. Use extreme care when mixing, storing or handling or serious personal injury may result.
• Use an approved fuel container.
• DO NOT smoke near fuel.
• DO NOT allow ames or sparks near fuel.
• Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.
• NEVER refuel a unit when the engine is HOT or RUNNING!
• DO NOT ll fuel tanks indoors. ALWAYS ll fuel tanks outdoors over bare ground.
• DO NOT overll fuel tank. Wipe up spills immediately.
• Securely tighten fuel tank cap and close fuel container after refueling.
• Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.
• Move at least 3m (10 ft.) from refueling location before starting the engine.
8
After use
• DO NOT store a unit with fuel in its tank. Leaks can
occur. Return unused fuel to an approved fuel storage container.
Storage - Fuel storage laws vary by locality. Contact
your local government for the laws affecting your area.
As a precaution, store fuel in an approved, airtight
container. Store in a well-ventilated, unoccupied build-
ing, away from sparks and ames.
IMPORTANT!
Stored fuel may separate. ALWAYS shake fuel container thoroughly before each use.
Mixing Instructions
1. Fill an approved fuel container with half of the
required amount of gasoline.
2. Add the proper amount of engine oil to gasoline.
3. Close container and shake to mix oil with gasoline.
4. Add remaining gasoline, close fuel container, and
remix.
IMPORTANT!
Spilled fuel is a leading cause of hydrocarbon emissions.
Some states may require the use of automatic fuel shutoff containers to reduce fuel spillage.
Filling the fuel tank
WARNING!
Minimize the Risk of Fire
1. Place the unit on a flat, level surface.
2. Clear any dirt or other debris from around the fuel filler cap.
3. Remove the fuel cap, and fill the tank with clean, fresh fuel.
4. Reinstall the fuel filler cap and tighten firmly.
5. Wipe away any spilled fuel before starting engine.
CAUTION!
Slowly remove the fuel cap only after stopping the engine
■ NEVER smoke or light res near the engine.
■ ALWAYS stop the engine and allow it to cool before
refueling.
■ ALWAYS Wipe all spilled fuel and move at least 3
meters (10 feet) from the fueling point and source before
starting.
■ NEVER place ammable material close to the engine
mufer.
■ NEVER operate the engine without the mufer and spark
arrester screen in place and in good working condition.
■ FUEL IS HIGHLY FLAMMABLE.
■ ALWAYS store gasoline in a container approved for
ammable liquids.
■ ALWAYS inspect the unit for fuel leaks before each
use. During each rell, check that no fuel leaks from
around the fuel cap and/or fuel tank.
If fuel leaks are evident, stop using the unit immediately. Fuel leaks must be repaired before using the unit.
■ ALWAYS move the unit at least 3 meters (10 feet)
away from a fuel storage area or other readily am-
mable materials before starting
the engine.
