OIL AND PETROL INFORMATION
OIL AND PETROL MIXING INSTRUCTIONS
Old and/or improperly mixed petrol are the main reasons
for the unit not running properly. Be sure to use fresh,
clean unleaded petrol. Follow the instructions carefully
for the proper petrol/oil mixture.
Definition of Blended Petrols
Today's petrols are often a blend of petrol and
oxygenates such as ethanol, methanol, or MTBE (ether).
Alcohol-blended petrol absorbs water. As little as 1%
water in the petrol can make petrol and oil separate. It
forms acids when stored. When using alcohol-blended
petrol, use fresh petrol (less than 60 days old).
Thoroughly mix the proper ratio of 2-cycle engine oil
with unleaded petrol in a separate petrol can. Use a 40:1
petrol/oil ratio. Do not mix them directly in the engine
petrol tank. See the table below for specific petrol and
oil mixing ratios.
NOTE: 3.8 liters (1 US gallon) of unleaded petrol mixed
with one 95 ml (3.2 oz) bottle of
2-cycle oil makes a 40:1 petrol/oil ratio.
+
Using Blended Petrols
If you choose to use a blended petrol, or its use is
unavoidable, follow recommended precautions:
• Always use the fresh petrol mix explained in your
operator's manual
• Always agitate the petrol mix before fueling the unit
• Drain the tank and run the engine dry before storing
the unit
Using Petrol Additives
The bottle of 2-cycle oil that came with your unit
contains a petrol additive which will help inhibit
corrosion and minimize the formation of gum deposits. It
is recommended that you use our 2-cycle oil with this
unit.
If unavailable, use a good 2-cycle oil designed for
air-cooled engines along with a petrol additive, such as
STA-BIL® Petrol Stabilizer or an equivalent. Add 23 ml
(0.8 oz) of petrol additive per gallon of petrol according
to the instructions on the container. NEVER add petrol
additives directly to the unit's petrol tank.
CAUTION: For proper engine operation
and maximum reliability, pay strict attention
to the oil and petrol mixing instructions on
the 2-cycle oil container. Using improperly
mixed petrol can severely damage the engine.

MAINTENANCE AND REPAIR INSTRUCTIONS
CARBURETOR ADJUSTMENT
Idle Speed Screw
The idle speed of the engine is adjustable through the air
filter/muffler cover (Fig. 29).
NOTE: Careless adjustments can seriously damage your
unit. An authorized service dealer should make
carburetor adjustments.
Check Petrol Mixture
Old and/or improperly mixed petrol is usually the reason
for improper unit performance. Drain and refill the tank
with fresh, properly-mixed petrol prior to making any
adjustments. Refer to Oil and Petrol Information.
Clean Air Filter
The condition of the air filter is important to the operation
of the unit. A dirty air filter will restrict air flow and
change the air/petrol mixture. This is often mistaken for
an out of adjustment carburetor. Check the condition of
the air filter before adjusting the idle speed screw. Refer
to Air Filter Maintenance.
Adjust Idle Speed Screw
WARNING: This unit will need to be running
during idle speed adjustment. Wear
protective clothing and observe all safety
instructions to prevent serious personal injury.
Also, DO NOT set unit on any surface
except a clean, hard area while starting or
performing any adjustments. Debris such as
gravel, sand, dust, grass, etc. could be
picked up by the air intake and thrown out
by the discharge opening, damaging unit,
property, or causing serious injury to
bystanders or operator.
If after checking the petrol mixture and cleaning the air
filter the engine still will not idle, adjust the idle speed
adjuster as follows.
1. Start the engine and let it run at a high idle for a
minute to warm up.
2. Set the blower/vacuum mode change-over lever to
the up position (Blower Mode). Refer to Operating as
a Blower.
NOTE: Setting the lever to the blower mode prevents the
vacuum bag from filling up while starting or
running the unit.
3. Move the throttle control and let the engine idle. If the
engine stops, insert a small phillips or flat blade
screwdriver into the hole in the air filter/muffler cover
(Fig. 29). Turn the idle speed adjuster in, clockwise,
1/8 of a turn at a time (as needed) until the engine
idles smoothly.
4. If the unit appears to be idling too fast, turn the idle
speed adjuster counterclockwise 1/8 of a turn at a
time (as needed), to reduce idle speed.
Fig. 29
Checking the petrol mixture, cleaning the air filter, and
adjusting the idle speed should solve most engine
problems. If not and all of the following are true:
• the engine will not idle
• the engine hesitates or stalls on acceleration
• there is a loss of engine power
Have the carburetor adjusted by an authorized service dealer.
REPLACING THE SPARK PLUG
Use a Champion RDJ7Y spark plug, or equivalent. The
correct air gap is 0.5 mm (0.020 inch). Remove the plug
after every 25 hours of operation and check its condition.
1. Stop the engine and allow it to cool. Grasp the plug
wire firmly and pull it from the spark plug.
2. Clean around the spark plug. Remove the spark plug
from the cylinder head by turning a 5/8-inch socket
counterclockwise.
3. Replace a cracked, fouled or dirty spark plug. Set
the air gap at 0.5 mm (0.020 inch) using a feeler
gauge (Fig. 30).
CAUTION: Do not sand blast, scrape or
clean electrodes. Grit in the engine could
damage the cylinder.
4. Install a correctly-gapped spark plug in the cylinder
head. Tighten by turning the 5/8-inch socket
clockwise until snug.
If using a torque wrench torque to:
12.3-13.5 N•m (110-120 in.•lb)
Do not over tighten.
