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 bolt (Pg. 17, Item D17).
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

A. Fuel Mixture
Your
Mantis
Single Edge Hedge Trimmer is powered by an
Echo Model SV-5H/2. This model has a two stroke, air cooled
engine which requires 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 gas o line/ 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 con tain ing meth a nol (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.
Mantis
brand
Premium 50:1 oil meets this proposed standard. Engine problems
due to in ad e quate lubrication caused by failure to use an ISO-L-
EGD approved oil, such as
Mantis
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 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.
