PREFACE
Thank you for choosing a general gasoline engine by our company. ::
Based on the latest engine technology at home and abroad, our Co. has individually developed general
gasoline engines with 4-stroke single cylinder, OHV and forced-air cooling. The engines are characte rized, by
advanced design, compact structure, reliable performance, convenient service low fuel consumption and easy speed
adjustment' They are widely used as ideal power in many fields such as generating set, tour, open working, public
place of entertainment, construction machine, agricultural machinery etc. the vital part bodies including cylinder
cover, crankcase, etc, are all cast formed with aluminum alloy. Laser-scanning technology, 3D shaping technology
and CN program processing technology used in the mould production upgrade the engine surface and
manufacturing accnracy obviously. Applying auto-press reducing system and centrifugal fly hammer regulating
system assure that assemblies equipped with the engine function smoothly and reliably as well as the engine start
easily' Besides, the introduction of the lubricant film-sensing protection system prevents accidental damage of the
engine for poor lubrication.
The manual gives information with respect to operation and maintenance of the general gasoline engine, and

additives or 2-stroke gasoline oil, as they haven't enough lubricption, which may shorten the
engine's service life.
O Check the engine with it stopped on a level ground.
SAE Engine oil recommended: SAEI0W-30. As viscosity varies
with regions and temperatures, so the Lubricant has to be
selected in accordance with our recommendation. (pic.3)
