1. SAFETY PRECAUTIONS
Please make sure you review each precaution carefully.
Pay special attention to statement preceded by the following words.
WARNING
CAUTION
“WARNING” indicates a strong possibility of severe personal injury or loss of life if
instructions are not followed.
“CAUTION” indicates a possibility of personal injury or equipment damage if
instructions are not followed.
WARNING
: 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 a
garage or carport, etc.
■Exercise extreme care when operating the engine near people or animals.
■Keep the exhaust pipe free of foreign objects.
WARNING
: REFUELING PRECAUTIONS
■Gasoline is extremely flammable and its vapors can explode if ignited.
■Do not refuel indoors or in a poorly ventilated area.
■Be sure to stop the engine prior to refueling.
■Do not remove fuel tank cap nor fill fuel tank while engine is hot or running.
Allow engine to cool at least 2 minutes before 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.
WARNING
: 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 cooling air intake (recoil starter area) and muffler side of the engine at
least 1 meter away from buildings, obstructions and other burnable objects.
■Keep the engine away from flammables and other hazardous materials (trash,
rags, lubricants, explosives).
WARNING : OTHER SAFETY PRECAUTIONS
■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.
■Do not touch the spark plug and ignition cable when starting and operating the
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
cause serious injury to the operator.

6. PREPARATIONS FOR STORAGE
1. DISCHARGE FUEL
WARNING
Use extreme caution when handling fuel. Gasoline is extremely flammable.
If you do not use the engine more than 1 month, discharge fuel to prevent gum in the fuel system and carburetor parts.
■Open the fuel shut-off valve (if equipped)
■Remove the drain screw of the carburetor float chamber and discharge fuel into a suitable container (do not use glass or
styrofoam).
2. ENGINE OIL
■Change the engine oil with fresh oil, See Periodic Maintenance Schedule table.
■Remove the spark plug, pour about 1 tsp. (5cc) of engine oil into the cylinder. Slowly pull the starter handle of the recoil starter 2
or 3 times, and replace the spark plug.
3. CLEAN AND STORE
■Slowly pull the recoil starter handle until resistance is felt and leave it in that position to keep moisture out of the combustion
chamber.
■Clean the engine thoroughly with a cloth, and store the engine indoors in a well ventilated, low humidity area.
7. SPARK ARRESTER (OPTIONAL)
In a dry or wooded area, it is recommendable to use the engine with a spark arrester. Some areas require the use of a spark arrester.
Please check your local laws and regulations before operating your engine.
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
CAUTION
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.
❶Spark arrester screen
❷Screw

8. EASY TROUBLESHOOTING
WHEN ENGINE WILL NOT START :
Perform the following checks before you take the engine to your Robin dealer (SUBARU Industrial Power Products dealer).
If you still have trouble after completing the checks, take the engine to your nearest Robin dealer (SUBARU Industrial Power
Products dealer).
1. Is there a strong spark across the electrode ?
(1) • Brake Type
Please confirm that brake do not operate.
• Stop switch Type
is the stop swich at the position “ ” (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.
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) • Primer Type
Push primer bulb three times 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.
• Choke Type
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.
