Evolution ® Engines -Year Warranty
This Evolution Engines product is guaranteed
to be free from defects in materials and
workmanship for a period
of 2 years from the date of purchase.
During this time, Evolution’s authorized
service center will repair or replace, at
their discretion, any defective parts,
without charge.
This warranty does not apply to damage
or defects resulting from misuse, neglect
or abuse; damage caused by customer
disassembly, use of substandard fuel,
use of incorrect accessories (glow plug,
propeller, etc.); or damage resulting from
a crash or any use of this engine other
than for which it is specifically intended.
Any of the above will automatically void the
warranty of the engine.
Should your engine require warranty or non-
warranty repair service, please package it
carefully and return it to the address at the
bottom, along with a copy of the original
invoice or receipt and a detailed letter
explaining the problems. Write your name,
address and daytime phone number clearly
on the letter and return it via UPS or insured
Parcel Post (Evolution Engines will not be
responsible for product lost en route).
For repairs not covered under warranty,
please specify in your letter whether you
want an estimate of the repair charges prior
to performing the service (which may cause
a slight delay). Unless otherwise specified,
all repaired engines will be returned C.O.D.
We will do everything we can to expedite the
service required to your Evolution product.

Maintenance
After each flying session:
1. Fully drain the fuel from the tank.
2. Start the engine and run it until the fuel is
completely run out of the engine.
3. Try starting the engine three more times or until
it will no longer fire. This gets all the fuel out of
the engine.
If the engine will not be used within 10 days, several
drops (about 10) of after run oil (Evolution Engine's
Blue Block Rust Inhibitor) should be applied into the
carburetor and the engine should be turned over for
a few seconds with the starter. This will prevent rust
and corrosion.
If you need additional help or have any questions,
please call Horizon’s Service Center. Horizon has trained
technicians who are qualified to answer your engine
questions.
