5. EASY TROUBLESHOOTING  
WHEN ENGINE DOES 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 the engine switch set ON?  
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.  
Is there a strong spark across the electrode?  
WARNING  
Wipe out spilled fuel carefully before checking.  
Place spark plug as far away from spark plug  
hole as possible.  
Do not hold spark plug by hand while checking.  
1. Remove the spark plug and connect it to the plug cap.  
Pull the starter handle while grounding spark plug  
against engine body using an insulated pliers.  
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.

7. "HOW-TO" MAINTENANCE  
INSPECTING THE SPARK  
PLUG  
Clean off carbon deposits on the  
spark plug electrode using a plug  
cleaner or wire brush.  
Check electrode gap.  
Adjust gap 0.7 mm to 0.8 mm  
(0.03 inches)  
0.7 to 0.8 mm  
(0.03 in.)  
Use a proper spark plug :  
NGK CMR6A  
ENGINE OIL CHANGE  
Initial oil change  
After 20 hours of operation  
Thereafter  
Every 50 hours of operation  
Refer to the recommended oil table  
on page 7.  
Always use the best grade and clean  
oil. Contaminated oil, poor quality oil  
and shortage of oil cause damage to  
engine or shorten the engine life.  
OIL CAPACITY・・・・EH025 : 80 mL  
EH035 : 100 mL  
CAUTION  
Make sure the fuel cap is tightly  
secured to avoid spillage.  
1) Remove the oil gauge.  
Be cautious to place the oil gauge in  
a place where it will not gather dirt,  
dust or other foreign matter.  
2) Place a cloth or paper towel to the  
area around the oil filler hole.

3) Remove the oil gauge, then tilt the  
engine and drain the oil into a pan or  
other receptacle.  
(EH035V) Remove the oil drain  
screw and drain the oil.  
4) Put the engine on a level surface,  
then fill with the oil up to the point of  
overflowing the filler neck. Pour the  
oil in from a squeeze bottle or other  
appropriate.  
5) After filling the engine with oil, rein-  
sert the oil gauge. Ensure that the oil  
gauge is tight, as if it loosens later oil  
will leak out.  
ADJUSTING CARBURETOR  
Adjusting idling rpm  
When adjust screw is turned right,  
engine rpm increases, and when it is  
turned left, rpm decreases.  
(Refer to illustration.)  
Normal idling rpm  
3000±100rpm  
NOTE:  
The carburetor greatly affects the  
performance of the engine.  
Since it has been adjusted carefully  
at our factory before shipment, avoid  
adjusting unless absolutely neces-  
sary.  
If adjustments are needed, contact  
your nearest dealer.

hard starting and/or poor engine opera-  
tion due to deteriorated fuel when you  
use the engine next time.  
Pour out the fuel in the tank from its  
filler neck.  
Push the primer pump of the carbure-  
tor until the fuel in it is thoroughly  
discharged.  
ENGINE OIL  
Change the engine oil with fresh oil.  
Remove the spark plug, pour about 2  
cc engine oil into the cylinder, slowly  
pull the starter handle of the recoil  
starter 2 or 3 times, and tighten the  
spark plug.  
CLEAN AND STORE  
Slowly pull the recoil starter handle  
until resistance is felt and leave it in  
that position.
