1. SAFETY PRECAUTIONS
Please make sure you review each precaution carefully.
EXHAUST PRECAUTIONS
●
Never inhale exhaust gasses.
They contain carbon monoxide, a
colorless, odorless and extremely
dangerous gas which can cause
unconsciousness or death.
●
Never operate the engine indoors or in
a poorly ventilated area, such as
tunnel, cave, etc.
●
Exercise extreme care when operating
the engine near people or animals.
●
Keep the exhaust pipe free of foreign
objects.
REFUELING PRECAUTIONS
●
Be sure to stop the engine prior to
refueling.
●
Do not overfill the fuel tank.
●
If fuel is spilt, wipe it away carefully and
wait until the fuel has dried before
starting the engine.
●
After refueling, make sure that the fuel
cap is secured to prevent spillage.
FIRE PREVENTION
●
Do not operate the engine while
smoking or near an open flame.
●
Do not use around dry brush, twigs,
cloth rags, or other flammable
materials.
●
Keep the engine at least 3 feet (1
meter) away from buildings or other
structures.
●
Keep the engine away from
flammables and other hazardous
materials (trash, rags, lubricants,
explosives).
Page 9
ENGLISHENGLISH
-2-
PROTECTIVE COVER
●
Place the protective covers over
the rotating parts.
If rotating parts such as the drive shaft,
pulley, belt, etc. are left exposed, they
are potentially hazardous.
To prevent injury, equip them with
protective covers or shrouds.
●
Be careful of hot parts.
The muffler and other engine parts
become very hot while the engine is
running or just after it has stopped.
Operate the engine in a safe area and
keep children away from the running
engine.
●
Never make adjustments on the
machinery while it is connected to the
engine, without first removing the
ignition cable from the spark plug.
Turning the crankshaft by hand during
adjusting or cleaning might start the
engine, and machinery with it, causing
serious injury to the operator.
●
Never run the engine with governor
disconnected, or operate at speeds in
excess of 3600 rpm load.
SURROUNDINGS
●
Operate the engine on a stable, level
surface free of small rocks, loose
gravel, etc
.
●
Operate the engine on a level surface.
If the engine is tilted, fuel spillage
may result.
NOTE
Operating the engine at a steep incline
may cause seizure due to improper
lubrication even with a maximum oil
level.
Page 10
-3-
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.
●
Wear snug fitting working clothes when
operating the engine.
Loose aprons, towels, belt, etc., may
be caught in the engine or drive train,
causing a dangerous situation.
●
Be careful of fuel spillage when
transporting the engine.
Tighten the fuel tank cap securely
and close the fuel strainer cock
before transport.
●
Do not move the engine while in
operation when it has been
removed from the equipment.
●
Keep the unit dry (do not operate it in
rainy conditions).

(See page 16 Maintenance Schedule.)
●
Use 4-stroke automotive detergent oil
of API service class SE or higher grade
(SG, SH or SJ is recommended).
●
If multi-grade oil is employed, oil
consumption tends to increase when
the ambient temperature is high.
CHECK FUEL
CAUTION
Do not refuel while smoking, near
an open flame or other potential
hazards.
NOTE
THIS ENGINE IS CERTIFIED TO OPERATE
ON AUTOMOTIVE UNLEADED GASOLINE.
●
Stop the engine and open the cap.
●
Use automotive unleaded gasoline only.
●
Close the fuel cock before filling the
fuel tank.
●
When filling the fuel tank, always use
the fuel filter.
●
Wipe off any spilled fuel before starting
the engine.

-
12
-
ENGLISHENGLISH
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.
Is there enough compression?
1. Pull the starter handle slowly and
check if resistance is felt.
2. If little force is required to pull the
starter handle, check if the spark
plug is tightened firmly.
3. If the spark plug is loose, tighten it.
Is the spark plug wet with
gasoline?
1.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.
2.When the electrode is dry, check
where the fuel stops. (Check the fuel
intake of the carburetor and fuel
strainer intake.)
3.In case the engine does not start with
well supplied fuel, try using fresh fuel.
Page 20

-
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.
Is there a strong spark across
the electrode?
1. Remove the spark plug and connect
it to the plug cap.
Pull the starter handle while
grounding spark plug against engine
body.
2. Try with a new spark plug if the
spark is weak or there is no spark.
3. The ignition system is faulty if there
is no spark with a new spark plug.
Take your engine to your nearest
Robin dealer.
Is your battery well charged ?
If your battery for the electric starter is
overly discharged, your engine will not
start.
Consult your nearest dealer or service
shop.
NOTE
The engine with oil sensor will stop
automatically when the oil level falls
below the prescribed limit.
The engine can not be started unless
the oil level is raised above the
prescribed limit.
Page 21
7.OIL SENSOR INSTRUCTIONS (OPTIONAL)
-
14
-
ENGLISHENGLISH
Is your oil sensor OK ?
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.
RESTARTING
●
Fill the crankcase with oil up to the
proper level.
●
As for restarting and operating the
engine, refer to Section 5,
"OPERATING YOUR ENGINE" on
page 8.
●
Check the wire connector from the
engine.
It must be connected securely to the
wire from oil sensor.
NOTE
●
Do not remove the oil sensor from
the engine for checking oil level
and refilling.
●
When selecting the engine oil,
refer to the chart on page 5.
Page 22
8. SPARK ARRESTER (OPTIONAL)
-
15
-
In a dry or wooded area, it is recommendable to use the product with a spark arrester.
Some areas require the use of a spark arrester. Please check your local laws and
regulations before operating your product.
The spark arrester must be cleaned regularly to keep it functioning as designed.
A clogged spark arrester :
● Prevents the flow of exhaust gas
● Reduces engine output
● Increases fuel consumption
● Makes starting difficult
If the engine has been running, the muffler and the spark arrester will be very hot.
Allow the muffler to cool before cleaning the spark arrester.
How to remove the spark arrester
1. Remove the flange bolts from the
muffler cover and remove the muffler
cover.
2. Remove the special screw from the
spark arrester and remove the spark
arrester from the muffler.
Clean the spark arrester screen
Use a brush to remove carbon deposits
from the spark arrester screen.
Be careful to avoid damaging the screen.
The spark arrester must be free of
breaks and holes. Replace the spark
arrester if it is damaged.
Install the spark arrester, and muffler
protector in the reverse order of
disassembly.
