OPERATION
WARNING: Be sure to read the fuel
information in the safety rules before you be-
gin. If you do not understand the safety rules,
donotattempttofuelyourunit.Contactanau-
thorized service dealer.
FUELING ENGINE
WARNING: Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
petrol. Before operation, petrol must be mixed
with a good quality 2-cycle air-cooled engine oil.
We recommend Partner brand oil mixed at a ra-
tio of 40:1 (2.5%). A 40:1 ratio is obtained by
mixing 5 liters of unleaded petrol with 0,125 liter
of oil. DO NOT USE automotive oil or boat oil.
These oils will cause engine damage. When
mixing fuel, follow instructions printed on oilcon-
tainer. Once oil is added to petrol, shake con-
tainer momentarily to assure that the fuel is thor-
oughly mixed. Always read and follow the
safety rules relating to fuel before fueling your
unit.
IMPORTANT
Experience indicates that alcohol blended fuels
(called gasohol or using ethanol or methanol)
can attract moisture which leads to separation
and formation of acids during storage. Acidic
gas can damage the fuel system of an engine
while in storage. To avoid engine problems,
empty the fuel system before storage for 30
days or longer. Drain the gas tank, start the en-
gine and let it run until the fuel lines and carbure-
tor are empty. Use fresh fuel next season. Nev-
er use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.

OPERATING INSTRUCTIONS FOR
USE WITH TRIMMER HEAD
WARNING: Always wear eye protec-
tion. Never lean over the trimmer head. Rocks
or debris can ricochet or be thrown into eyes
and face and cause blindness or other serious
injury.
Beforetrimming,bringenginetoaspeedsuffi-
cient to cut material to be trimmed.
Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than full throttle.
At lower speeds, there is less engine noise and
vibration. The cutting line will last longer and will
be less likely to “weld” onto the spool.
Always release the throttle trigger and allow
the engine to return to idle speed when not
cutting.
To stop engine:
SRelease the throttle trigger.
SMove the ON/STOP switch to the STOP
position.
TRIMMER LINE ADVANCE
Advancelineby tappingthebottomof thecut-
ting head lightly on the ground while engineis
running at full speed. The metal line limiter
blade attached tothe guard will cut the lineto
the proper length.
WARNING: Use only 2,4 mm diameter
line. Other sizes of line will not advance properly
and can cause serious injury. Do not use other
materials such as wire, string, rope, etc. Wire
can break off during cutting and become a dan-
gerous missile that can cause serious injury.
CUTTING METHODS
WARNING: Useminimum speedand
do not crowd the line when cutting around
hard objects (rock, gravel, fence posts, etc.),
whichcandamagethetrimmerhead,become
entangled in the line, or be thrown causing a
serious hazard.
SThe tip of the line does the cutting. You will
achieve the best performance and minimum
line wear by not crowding the line into the
cutting area. The right and wrong ways are
shown below.

SThe line will easily remove grass and weeds
from around walls, fences, trees and flower
beds, but it also can cut the tender bark of
trees or shrubs and scar fences.
SFor trimming or scalping, use less than full
throttle to increase line lifeand decreasehead

SNear objects around which the line can
wrap such as small posts, trees or fence
wire.
SFor mowing or sweeping, use full throttle for a
good clean job.
TRIMMING -- Hold the bottom of the trimmer
head about 8 cm above the ground and at an
angle. Allow only the tip of the line to make
contact. Do not force trimmer line into work
