especially if your eyes are affected.
■Batteries generate hydrogen gas, which can be highly explosive. Do not smoke or
allow flames or sparks near a battery, especially during charging.
■Charge the battery in a fully ventilated location.
■Be sure to confirm Battery polarity.
CAUTION
: PRE-OPERATION CHECKS
■Carefully check fuel hoses and joints for looseness and fuel leakage. Leaked fuel
creates a potentially dangerous situation.
■Check bolts and nuts for looseness. A loose bolt or nut may cause serious engine
trouble.
■Check the engine oil and refill if necessary.
■Check the fuel level and refill if necessary. Take care not to overfill the tank.

6. OPERATING YOUR ENGINE
(See Fig. 󱯔)
1. STARTING
(1) Open the fuel valve. (See Fig.󱯔-①)
(2) Turn the STOP SWITCH to the position “ I ” (ON).
(See Fig.󱯔-②)
(3) Set the speed control lever 1/3 of the way towards the high
speed position. (Except EX30) (See Fig.󱯔-③)
(4) Close the choke lever. (See Fig.󱯔-④)
■If the engine is cold or the ambient temperature is low,
close the choke lever fully.
■If the engine is warm or the ambient temperature is high,
open the choke lever half-way, or keep it fully open.
(5) Pull the starter handle slowly until resistance is felt. This is
the “compression” point. Return the handle to its original
position and pull swiftly. Do not pull out the rope all the way.
After starting the engine, allow the starter handle to return to
its original position while still holding the handle.
(See Fig.󱯔-⑤)
2. RUNNING
(1) After the engine starts, set the speed control lever at the
low speed position (L) and warm it up without load for a few
minutes. (See Fig.󱯖-①)
(2) Gradually move the speed control lever toward the high
speed position (H) and set it at the required engine speed.
(See Fig.󱯖-②)
■Whenever high speed operation is not required, slow the
engine down (idle) by moving the speed control lever to save
fuel and extend engine life.
3. STOPPING
(1) Set the speed control lever at the low speed position and
allow the engine to run at low speed for 1 or 2 minutes
before stopping.
(See Fig.󱯘-①)
(2) Turn the STOP SWITCH (or KEY SWITCH) counterclock-
wise to the position “○” (OFF). (See Fig.󱯘-②)
(3) Close the fuel valve. (See Fig.󱯘-③)
(4) Pull the starter handle slowly and return the handle to its
original position when resistance is felt. This operation is
necessary to prevent outside moist air from intruding into
the combustion chamber. (See Fig.󱯘-④)
※STOPPING ENGINE WITH THE FUEL VALVE
Close the fuel valve and wait for a while until the engine stops.
Avoid to let the fuel remain in the carburetor over long periods,
or the passages of the carburetor may become clogged with
impurities, and malfunctions may result.
(6) After starting the engine, gradually open choke by turning
the choke lever and finally keep it fully opened.
Do not fully open the choke lever immediately when the
engine is cold or the ambient temperature is low, because
the engine may stop. (See Fig.󱯔-⑥)
FOR ELECTRIC STARTER MODELS.
Insert the key into the key slot and set it at the “ I ” (ON)
position. Turn it to the right (START position) to start the
engine. (See Fig.󱯔-⑤)
■Do not operate the electric starter continuously for more
than 5 secounds, even if the engine dose not start.
■If the engine failed to start, set the key to the “ I ” (ON)
position and wait for about 10 secounds before retrying.
■Never turn the key switch to the START position while
engine is running.
Pulley fitting onto PTO shoulder
For proper pulley fitting onto PTO shoulder, make round
chamfer at pulley corner.
Sharp edge of pulley corner strikes PTO shoulder. In this
improper condition, bolt will be loosened, and PTO damaged
finally.

9. OIL SENSOR INSTRUCTIONS
1. FUNCTION OF OIL SENSOR
The engine will stop automatically when the oil level falls below
the safety limit. The engine cannot be started unless the level is
raised above the prescribed limit. (See Fig.󱯐-②)
2. RESTARTING
(1) Fill the crankcase with oil up to the proper level.
(2) As for restarting and operating the engine, refer to section
“6. OPERATING YOUR ENGINE” on page 8 .
■Check the wire connector from the engine. It must be
connected securely to the wire from oil sensor.
■When selecting the engine oil, refer to page 5 for the
recommended oil.
(OPTIONAL)
10. EASY TROUBLESHOOTING
WHEN ENGINE WILL NOT START :
Perform the following checks before you take the engine to
your Robin dealer. If you still have trouble after completing the
checks, take the engine to your nearest Robin dealer.
1. Is there a strong spark across the
electrode ?
(1) Is the stop switch at position “ I ” (ON)?
(2) Remove and inspect the spark plug.
If the electrode is fouled, clean or replace it with new one.
(3) Remove the spark plug and connect it to the plug cap. Pull
the starter handle while grounding spark plug against engine
body. Try with a new spark plug if the spark is weak or there
is no spark.
The ignition system is faulty if there is no spark with a new
spark plug.
WARNING
■Wipe out spilled fuel carefully before testing.
Place spark plug as far away from spark plug
hole as possible.
■Do not hold spark plug by hand while pulling
recoil starter.
NOTE
The engine with oil sensor will stop automatically when the oil
level falls below the prescribed limit.
Unless the oil level is raised above the prescribed limit, the
engine will stop immediately after starting.
2. Is there enough compression?
Pull the starter handle slowly and check if resistance is felt.
If little force is required to pull the starter handle, check if
the spark plug is tightened firmly. If the spark plug is loose,
tighten it.
3. Is the spark plug wet with gasoline?
(1) Is the fuel valve opened?
(2) Choke (close choke lever) and pull the starter handle five or
six times. Remove the plug and check if its electrode is wet.
If the electrode is wet, fuel is well supplied to your engine.
(3) When the electrode is dry, check where the fuel stops.
(Check the fuel intake of the carburetor.)
(4) In case the engine does not start with well supplied fuel, try
using fresh fuel.
4. Is the battery well charged?
If the battery for the electric starter is discharged, the engine
will not start.
