FUELING AND REFUELING THE PRUNER
FUEL MIXTURE
This product is powered by a 2-cycle engine and requires
pre-mixing gasoline and 2-cycle lubricant. Pre-mix unleaded
gasoline and 2-cycle engine lubricant in a clean 1 gallon
container approved for gasoline.
 This engine is certified to operate on unleaded gasoline
intended for automotive use.
 Mix high quality 2-cycle engine lubricant at 2.6 oz. per
gallon.
 Do not use automotive lubricant or 2-cycle outboard
lubricant.
 DO NOT mix quantities larger than usable in a 30-day
period.

 Loosen fuel cap slowly. Rest the cap on a clean
surface.
 Carefully pour fuel into the tank. Avoid spillage.
 Prior to replacing the fuel cap, clean and inspect the
gasket.
 Immediately replace fuel cap and hand tighten. Wipe up
any fuel spillage.
NOTE: It is normal for smoke to be emitted from a new
engine after first use.
ASSEMBLY
Always shut off engine before fueling. Never add fuel to
a machine with a running or hot engine. Move at least
30 ft. from refueling site before starting the engine. Do
not smoke! Failure to heed this warning could result in
serious personal injury.

OXYGENATED FUELS

Some conventional gasolines are blended with alcohol or an
ether compound. These gasolines are collectively referred
to as oxygenated fuels. To meet clean air standards, some
areas of the United States and Canada use oxygenated fuels
to help reduce emissions.
If using an oxygenated fuel, make sure it is unleaded and
meets the minimum octane rating requirements. Before using
an oxygenated fuel, try to confirm the fuel's contents. Some
states/provinces require this information to be posted on the
pump. The following are the EPA approved percentages of
oxygenates:
Ethanol (ethyl or grain alcohol) 10% by volume. You
may use gasoline containing up to 10% ethanol by volume.
Gasoline containing ethanol may be marketed under the
name "Gasohol." Do not use E85 fuel.
MTBE (methyl tertiary butyl ether) 15% by volume. You
may use gasoline containing up to 15% MTBE by volume.
Methanol (methyl or wood alcohol) 5% by volume. You
may use gasoline containing up to 5% methanol by volume
as long as it also contains cosolvents and corrosion inhibi-
tors to protect the fuel system. Gasoline containing more
than 5% methanol by volume may cause starting and/or
performance problems. It may also damage metal, rubber,
and plastic parts of the product or your fuel system.
If you notice any undesirable operating symptoms, try anoth-
LUBRICANT
er service station or switch to another brand of gasoline.

NOTE: Fuel system damage or performance problems re-
20 cc (20 ml)
sulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates stated previously are
not covered under warranty.
