Operation
2. Place the front side handle over the two 1/4-28 studs
protruding from the frame bar in front of the gear housing. The
handle grip must be pointing away from the cutting blades as
illustrated (Figure 1). On Model 2230S use the set of studs
which places the handle in the most comfortable position for
you. Place the thread protectors over the set of studs that you
choose not to use at this time to protect the threads. Secure
the handle in place using two 1/4-28 flange locking nuts
provided. The nuts should be tightened enough to keep the
handle from moving but not so tight as to crush the plastic.
If the engine needs to be reinstalled:
1. Install the engine by first aligning the hex drive on the
trimmer gear housing with the single sided hex socket in the
engine.
2. Slide the engine over the 1" diameter stem containing
the hex drive on the gear housing until it is seated all the way
down on the gear housing. Tighten the 7/8" Phillips Pan Head
Screw (Pg. 12, Key #22).
3. Press shock absorbers into sockets on the gear housing
followed by the spacer tubes. Secure the handle and tubing
support channel, spacer, and bracket with the 1/4-20 hex bolts
and locking nuts supplied.
4. With the stop switch in the stop position, and the
engine not running, check the throttle for proper operation.
Grasp rear handle with left hand, depressing the lockout trigger
until it stops when the carburetor lever hits the carburetor
case. Release the throttle trigger and make sure the throttle
returns to the idle position, when the carburetor level rests on
the idle screw. Throttle movement should be smooth and
unobstructed.
C. Break-In Procedure
There are no special requirements for engine break-in. After
normal operation and two (2) tanks of fuel, engine break-in is
complete.
If adjustments are necessary, follow Special Carburetor
Adjustment Procedures on this supplementary Operator's
Information Sheet. All other adjustments and maintenance
procedures are in the complete Owner’s Manual.
A. Fuel Mixture
Your Little Wonder Single Edge Hedge Trimmer is powered by
an Echo Model SV-4B(H) Type IE, and Double Edge Hedge
Trimmer is powered by an Echo Model SV-4B(H2) Type IE.
Both models have two stroke, air cooled engines which require
a fuel mixture of gasoline and 2-stroke oil.
1. Important Engine Information
This unit is certified to operate on approved two-stroke fuel
(a mixture of 2-stroke oil and gasoline/ gasohol).
2. Fuel Statement
Gasoline - Use 89 Octane [R+M/2] gasoline or gasohol
known to be good quality. Gasohol may contain up to 10%
Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl
ether). Gasohol containing methanol (wood alcohol) is NOT
approved.
3. Two-Stroke Oil
A two-stroke engine oil meeting proposed ISO-L-EGD
Standard (ISO/CD 13738), must be used. LW brand Premium
50:1 oil meets this proposed standard. Engine problems due to in-
adequate lubrication caused by failure to use an ISO-L-EGD
approved oil, such as LW Premium 50:1 Two-stroke Oil, will
void the two-stroke engine warranty. (Emission related parts
only are covered for two years, regardless of two-stroke oil used,
per the statement listed in the EPA Phase I/California Emission
Defect Warranty Explanation.)
B. Mixing Fuel
1. Pour 1/2 of the gasoline into a safe container. DO NOT
mix fuel in the engine fuel tank.
2. Add the oil to the gasoline and mix.
3. Add the remaining gasoline and remix.
4. Install fuel cap and wipe spilled fuel from container and area.
5. Important, two stroke fuel separates and ages. Do not mix
more than you will use in a month. Shake fuel container to
thoroughly mix fuel before each use. Do not attempt to run
your engine on gasoline only, use the proper fuel mixture.
