General Safety Instructions
Work Safely
Shindaiwa hedge trimmers operate at
very high speeds and can do serious
damage or injury if they are misused
or abused.
Never allow a person without
training or instruction to operate your unit!

equipment of any kind if you are tired
or if you are under the inuence of alcohol, drugs, medication or any other
substance that could affect your ability or judgement.
WARNING!
Minimize the Risk of Fire!
ALWAYS check unit for fuel leaks
before use. Check for leaks around
fuel tank cap while refueling. If fuel
leaks are found immediately stop
using the unit. Fuel leaks must be
repaired before using unit.
ALWAYS move the unit to a place
well away from a fuel storage area
or other readily ammable materials
before starting the engine.
Always wear eye, ear,
and hand protection while
operating this unit!
Always stop the
engine before
removing branches
or debris from the
cutters! Never allow
the cutters to contact
buildings or other
hard objects!
Always stop the engine
and install the blade cover
before moving to another
work site, and maintain a
rm footing while operating
or carrying the trimmer.
Never cut metal objects or

The emission control system for the engine is EM/TWC (Engine Modication and 3-way Catalyst) and for
the fuel tank the Control System is EVAP (Evaporative Emissions) or N (for nylon tank). Evaporative emission may be applicable to California models only.
An Emission Control Label is located on the unit. (This is an EXAMPLE ONLY; information on label varies by en-
gine FAMILY).
PRODUCT EMISSION DURABILITY (EMISSION COMPLIANCE PERIOD)
The 300 hour emission compliance period is the time span selected by the manufacturer certifying the engine
emissions output meets applicable emissions regulations, provided that approved maintenance procedures are
followed as listed in the Maintenance Section of this manual.

Mixing Fuel
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.
Hybrid 4TM Mixture Oil - Engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD standards must be
used. Shindaiwa highly recommends using Shindaiwa Red ArmorTM engine oil in all Shindaiwa Hybrid 4TM engines 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. Engine problems
due to inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD certied
oil will void the engine warranty.
IMPORTANT!
TM
Shindaiwa Red Armor
in all Shindaiwa engines sold in the past, regardless of ratio specied in those
manuals.
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.
engine oil may be mixed at 50:1 ratio for application
IMPORTANT!
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.
7
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 shut-off containers to reduce fuel spillage.
After use
• DO NOT store a unit with fuel in its tank. Leaks can occur. Return unused
fuel to an approved fuel storage container.
Filling the Fuel Tank
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 building,
away from sparks and ames.
IMPORTANT!
Stored fuel may separate. ALWAYS
shake fuel container thoroughly before each use.
WARNING!
Minimize the Risk of Fire
NEVER ■ smoke or light res near
the engine.
■ stop the engine and
ALWAYS
