OPERATION
CHECK UP OF NUTS AND OTHER HARDWARES
• Check up loose nuts, bolts and screws before using the unit every day.
FUEL
• Fuel used for this model is a mixture of regular grade gasoline and ECHO brand motor oil or an aircooled two stroke
engine oil of a reputable brand name.
• Mixture ratio is
Gasoline 32 parts: Oil 1 part.
iz: o — Fuel mixture at a ratio other than 32 : 1 may
cause malfunction of the engine*
(NOTE)
32:1 Ratio is applicable with special oil
approved by ECHO*
— Pour 1/2 gasoline into safe container, add oil and mix thoroughly.
— Now add the remainder of gasoline and mix again.
— Do not use motor oil other than that
recommended above.
— Do not mix directly in engine fuel tank.

STARTING COLD ENGINE
• Stand engine upright on a level surface.
• ignition switch to "start/run" position.
• Turn choke shutter to START (close) position. (Towards the flexible pipe)
• Open throttle trigger to a fast idle. (Squeeze it slightly)
• Pull recoil starter until engine fires.
• Turn choke shutter to full RUN (open) position, and if necessary, start engine again and allow to warm up before using
(Caution)
Recoil starter: Use short pulls-only 1/2 —2/3 of the starter rope for starting.

STARTING WARM ENGINE
• Ignition switch to "start/run" positron.
• Puli starter handle until engine fires.
“ Do not use the choke.
STOPPING ENGINE
• Release throttle trigger and allow engine to cool at an idle for a few minutes,
* Ignition switch to "stop" position.
(Note) When engine does not stop, shift choke shutter to close position.
Check and repair switch before starting engine again.
OPERATING BLOWER
• Allow the engine to warm up at a fast idle for a few
minutes,
• ECHO PB-200 can be run at any speed between an idle of
2300-2700 RPIV1 and maximum load speed of 7500 RPIVL
The velocity of the air stream can therefore readily be
controlled from a gentle breeze to a high speed blast
moving at approximately 103 MPH (46 m/sec) which will
move debris ranging from garden leaves to bottles and can
accumulated in sports stadiums.
— Use a low speed to blow dry leaves from a lawn or
flower bed,
— Use a medium to high speed to clean grass and leaves
from walks, patios and drives,
— Use a high speed to move gravel, dirt, snow, bottles or
cans from a driveway, street, parking lot, or stadium.
(Caution)
Do not point the blower pipe in the direction of people or
pets.
Always wear safety glasses and use a face f ilter mask.
Read carefully "Rules for safe operation" on page 1.

MAINTENANCE AND CARE
REMOVING ENGINE COVER (Remove engine cover to clean air filter, spark plug and muffler.)
• Unfasten rubber band at bottom of machine.
• Pull out engine cover, pushing two holders as shown.
• Do not adjust carburetor unless necessary,
• To adjust carburetor, proceed as follows:
— Low speed needle: 7/8 — 13/8
— High speed needle: 7/8 — 1-3/8
— Turn the corresponding needle clockwise until lightly
seated and return the screw by the number of turns
indicated above.
• Idle adjustment: (2300-2700 rpm)
Adjust idle speed to a smooth and consistent minimum.
• If you have trouble with carburetor, see your distributor/
dealer*
CARBURETOR

High speed needle
idle adjust needle
AIR FILTER
• Clean every day.
— Take out retaining spring and pull up grid and air filter
to clean*
— Brush off dust lightly or wash it in gasoline.
— When you wash it in gasoline, dry completely before
put it
- 6 -

FUEL STRAINER
• Check periodically,
— Do not allow dust to enter into fuel tank.
— Clogged strainer will cause difficulty in starting engine
or abnormalities in engine performances,
- Pick up fuel strainer carefully through fuel inlet port
with a piece of steel wire or the like.
— When strainer is dirty, wash it in gasoline.
SPARK PLUG
CYLINDER FINS
MUFFLER AND EXHAUST PORT
• Check periodically.
— The standard spark gap is 0,6—0,7 mm (0.023-
0.028 in,}.
— Correct spark gap if it is wider or narrower than the
standard gap,
— When it is deposited with carbon or stained, clean it
before fitting to engine.
• Fastening torque = 145—155 kg.cm (125—135 in.lb).
(Caution! Do not over tighten plug.
• Check periodically.
— Clogged fins result in poor engine cooling.
- Clean passage of air between cylinder fins to let cooling
air pass easily.
• Carbon deposit in cylinder exhaust port and muffler will
cause drop of engine output and sparking from muffler.
— Muffler can be removed by taking off muffler cover.
— Be careful not to scratch cylinder or piston when
cleaning cylinder exhaust port.
TROUBLE SHOOTING
• FAILURES such as difficulty in starting engine, irregularity in functions and abnormality in blowing performances
can normally be prevented completely if a little attention is paid in advance,
• Such failures can be readily disposed of even by a beginner.
• When engine does not function properly, check following 3 points systematically in particular:
— Whether compression of engine is adequate or not.
— Whether fuel system is in good condition and fuel is supplied fluently, or not.
— Whether electrical system is in good condition and spark plug sparks correctly, or not,
• When there is serious trouble with the unit, do not try to repair by yourself, but have your distributor or dealer do it
for you.
• Details of TROUBLE SHOOTING refer to Table 1 and 2.
— Refer to chart to locate the problem and repair as necessary.
