CAUTION
• It may take some time before the oil
begins to discharge once the oil has
been added to a new product or when oil
has been added to an empty tank. Do
not turn the pruner on at a high speed
in such circumstances.
• When a new chain is to be used,
immerse the chain in chain oil for some
time prior to installing it on the pruner,
or pour the oil directly on to the chain
and the guide bar, after installing it on
the pruner. If they are not properly lubri-
cated with oil the pruner may seize.
The regulating screw has three positions, Minimum,
Intermediate and Maximum, only.
The regulating screw is set to Intermediate at the time
of shipping. It is recommended that the product be used
with this setting for ordinary use.
•
Increase the discharging rate when cutting hard
branches or branches with a lot of resin (pitch),
or when the viscosity of the oil is high during
winter.
1. Insert a minus screw driver into the regulating
screw at the bottom of the main unit.
2. When applying pressure with the minus screw
driver, turn the screw to the right (clockwise) to
reduce the discharging rate and to the left
(counterclockwise) to increase the discharging
rate.
3. Turn the engine on and turn the saw chain, with
the guide bar facing the ground or tree. Oil will
attach to the ground or tree, if the oil is
discharging.
CAUTION
• Using the pruner with a saw chain too loose
may result in the saw chain becoming
dislodged and could cause an accident.
Please be sure to check the tension of
the saw chain before starting any work.

WARNING
POTENTIAL HAZARD
• Gasoline contains gasses that can build
up pressure inside a gas tank.
WHAT CAN HAPPEN
• Fuel can be sprayed on you when
removing gas cap.
HOW TO AVOID THE HAZARD
• Remove fuel cap slowly to avoid injury
from fuel spray.
Use clean, fresh lead-free gasoline, including
oxygenated
or
reformulated
gasoline, with an octane rating of 89
or higher. To ensure freshness, purchase only the quantity
of gasoline that can be used in 30 days. Use of lead-free
gasoline results in fewer combustion chamber deposits and
longer spark plug life. Use of premium grade fuel is not
necessary or recommended.
