1. SAFETY PRECAUTIONS
Please make sure you review each precaution carefully.
EXHAUST PRECAUTIONS
NNever 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 operat-
ing 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 while smoking or near
an open flame.
Do not use around dry brush, twigs,
cloth rags, or other flammable materi-
als.
Keep the engine at least 3 feet
(1 meter) away from buildings or
other structures.
Keep the engine away from flamma-
bles and other hazardous materials
(trash, rags, lubricants, explosives).

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 opera-
tor.
SURROUNDINGS
Operate the engine on a stable, level
surface free of small rocks, loose
gravel, etc.
NOTE
Operating the engine at a steep
incline may cause seizure due to
improper lubrication even with a
maximum oil level.

Drain the fuel when transporting
the engine.
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).
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 seri-
ous 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.

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 complet-
ing the checks, take the engine to
your nearest Robin dealer.
Is the engine switch set ON?
Is there enough compres-
sion?
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 carbure-
tor and fuel strainer intake.)
3. In case the engine does not start
with well supplied fuel, try using
fresh fuel.

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 ground-
ing 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.
