of the shaft bolt facing up.
2. Remove the shaft bolt, bolt guard,
Holder B and the retainer clip(s) from
the output shaft.
IMPORTANT!
The shaft bolt, bolt guard, and retainer
clips are not used with a trimmer head
cutting attachment. Save these parts for
future blade installation.

4. Rotate the holder until the hole in the
holder aligns with the notch on the
gearcase flange. Using the hex wrench,
lock the gearcase as shown.
5. While holding the holder with the hex
wrench, thread the trimmer head onto
the gear-shaft and install securely using
hand pressure. Turn counterclockwise

Filling The Fuel Tank
1. Place the unit on a flat, level surface,
and wipe any debris from around the
fuel cap.
2. Remove the fuel cap.
3. Fill the tank with clean, fresh fuel.
4. Replace the cap, and wipe away any
spilled fuel before starting the engine.
IMPORTANT!
Mix only enough fuel for your immediate
needs! If fuel must be stored longer
than 30-days, it should first be treated
with a stabilizer such as STA-BIL™ or
equivalent product!
CAUTION!
Never attempt to mix fuel in the unit’s
fuel tank. Always mix all fuels in a
clean approved container.
Use only fresh, clean unleaded gasoline
with a pump octane rating of 87 or
higher.
Mixing fuel with a Premium 2-cycle
mixing oil designed for use with high-
performance 2-cycle air-cooled engines.
Refer to the following examples of 50:1
fuel to oil mix quantities:
Gasoline 2-cycle mixing oil
liters
milliliters
2.5 l ............................. 50 ml
5 l ................................100 ml
10 l ..............................200 ml
20 l ..............................400 ml
Mixing Fuel
WARNING!
Minimize the risk of fire,
burns, and personal injury!
STOP
engine before refueling.
ALWAYS
allow the engine to cool
before refueling
ALWAYS
open the fuel cap slowly
to allow any pressure build-up
in the tank to release fuel vapor
slowly.
ALWAYS
transport and store fuels
in an approved container.
Avoid overfilling and wipe-up all
spilled fuel. Move the engine at
least 3 meters from the fueling
point, storage area, and other
readily flammable materials before
restarting.
ALWAYS
inspect the unit for fuel
leaks before each use. During
each refill, make sure there are no
fuel leaks around the fuel cap and/
or tank. If a fuel leak is evident,
stop using the unit immediately.
Fuel leaks must be repaired before
using the unit.
NEVER
smoke or light any fires
near the engine or fuel source.
NEVER
place any flammable ma-
terial near the engine or muffler.
NEVER
operate the engine without
the muffler in good working condi-
tion.
ALWAYS
move the unit to a place
well away from a fuel storage area
or other readily flammable materi-
als before starting the engine.
CAUTION!
Some gasolines contain alcohol as
an oxygenate! Oxygenated fuels may
cause increased operating tem-
peratures. Under certain conditions,
alcohol-based fuels may also reduce
the lubricating qualities of some mixing
oils. Never use any fuel containing
more than 10% alcohol by volume!
Generic oils and some outboard motor
oils may not be intended for use in
high-performance air cooled 2-cycle
engines, and should never be used in
your Shindaiwa engine!
CAUTION!
This engine is designed to operate on
a 50:1 mixture consisting of unleaded
gasoline and a premium 2-cycle mixing
oil only. Use of Non-approved mixing
oils can lead to excessive maintenance
costs and/or engine damage.
