Gasoline is extremely flammable and is explosive under certain conditions.
Do not smoke or allow sparks or flames in your work area.
Never run the engine in a closed area. The exhaust contains poisonous carbon monoxide gas that may
cause loss of consciousness and lead to death.

When the engine speed increases, the drive pulley
will push the belt by centrifugal force from the six
rollers.
Then, the pitch circle of belt in the drive pulley will
be larger.
The belt at the drive pulley is forced to move to the
center of the shaft, and then the radius of pitch circle
is decreased.
The transmission ratio is therefore altered by the
alteration of pitch circle's radius.
(In the drawing, "H" means high speed; "L" means
low speed)

Due to increasing engine speed, the rollers push the
movable drive face by centrifugal force. Then, the
belt is pressed and enlarges its turning radius. The
aluminum fan is installed on the exterior of the fixed

The belt is made of rubber fiber. It is resistant to heat,
pressure, and abrasion. The inner side of the belt is toothed.

Because the revolving radius of the V-Belt at the

There is a Torque Cam on the Movable Drive Face.
The torque Cam is loaded from the outside. When the outside load is higher than the engine's output, the
pulley of the fixed shaft and belt slip to make the Movable Drive Face move along the inner side of the
cam and compensate to increase to high torque (toward low speed) and make the engine maintain
smooth running with original revolution.

CAUTION: The battery emits flammable and explosive fumes during normal operation. Keep away
from sparks, open flame, and other possible sources of ignition. Always provide adequate ventilation
during charging and maintenance of the battery. The battery contains sulfuric acid (an electrolyte).
Contact with skin or eyes may cause severe burns or blindness. Always wear protective clothing and eye
protection when servicing the battery. The electrolyte is toxic. If swallowed, drink large quantities of
water or milk and seek medical attention immediately, or contact a poison control center.

Testing the battery:
• Measure the battery voltage using a multi-meter
set to Voltage
• A fully charged battery should read 13.0-13.5V. An
under charged or faulty battery will be below
12.0V.
• If the battery is showing under charge condition,
charge the battery using a trickle charger at 7
amps for 10 hours. When charging the battery, it
should be removed from the unit. Connect the
charger lead to the battery before turning on the
charging unit. Turn the charging unit off before
disconnecting the charging leads from the battery.
Retest the battery voltage. If the battery voltage
shows an under charge condition after charging,
replace the battery.

DO NOT place the new battery on a charger as this can
damage the cell plates and make the battery unusable.
Battery installation:
2i
• Place the battery in the battery compartment.
• Clean the battery terminals and lead connectors of all dirt
and corrosion.
• Attach the positive (RED) lead to the [+] positive
terminal of the battery first.
• Attack the negative (BLACK) lead to the [-] negative
terminal of the battery next.
• Check the lead routing to ensure they are clear of
obstruction and do not fall between the battery and unit
body where they could be abraded or otherwise damaged.
• Attach the battery retainer strap to secure the battery in
place.

• If the battery become discharged or shows low
voltage you can recharge the battery using a 12 volt
battery trickle charger.
• Connect the positive lead of the charger to the
positive terminal of the battery.
• Connect the negative lead of the charger to the
negative terminal of the battery.
• Turn on the charger and allow the battery to charge
from 4 to 6 hours.
• Test the battery voltage after charging it should give
a reading of between 12-and 13 volts.
• If after charging the battery is still indication a low
voltage or the battery will not hold the charge for
more than a day or two the battery should be
replaced.
ETON recommends replacing the battery every two years for optimal performance.

New battery preparation:
• The new battery is shipped dry with the electrolyte in a
separate container. Remove the battery cell caps and install the
electrolyte in the battery cells. CAUTION: Electrolyte contains
sulfuric acid that can cause severe burns if contact is made
with the skin or eyes. • Allow the battery to completely absorb
the electrolyte (approximately one (1) hour). The battery
should have a full charge. The battery is a gel acid battery and
will not show any liquid electrolyte when fully absorbed.
