STARTING COLD ENGINE
Slide ignition switch to START /RUN position,
Push primary pump bulb 3 to 4 times {or until fuel is
seen in fuel return line).
Pull choke knob to cold start position and pull starter
until engine fires.
Push choke knob to run position and start engine and if
necessary, restart the engine again and allow to warm up
for a few minutes before using.
After idling, gradualiy open throttle and cutter head will
start to operate as the engine attains clutch engagement
speed of 3000 ~ 3400 RPM approximately.
{NOTE}
Recoil starter: Use short pulls — only 1/2—2/3 of starter
rope for starting. Do not aliow the rope to snap back in.
Always hoid the unit firmly.
STARTING WARM ENGINE
* If fuel tank was not run dry, pull starter one to three
times and engine should fire, Do not use choke.
e |f fuel tank was run dry, after refilling, push the primer
bulb 3 to 4 times then pull the starter, Do not choke.
if the engine does not start in 5 pulls, push the primer
bulb twice more or until fuel is seen flowing in the return
line and start.
STOPPING ENGINE
e Release throttie trigger and allow to run at an idle speed,
e Turn ignition switch to “STOP” position.
\
OPERATING THE TRIMMER
® Adjust handle to a convenient position for trimming as
instructed on page 4.
Allow the engine to warm up at a fast idie for a few
minutes,
Increase engine speed as necessary.
When mowing weeds or grass, swing the cutter head from
right to left as you move forward.
— Avoid striking any obstruction such as rocks, stones or
tree stumps which can damage the cutter head. Do not
cut into the ground.
— To avoid damage to the engine, do not run the engine
unloaded at full throttle.
In the event that the cutter strikes an obstruction or is
otherwise prevented from rotating in normal operation,
the clutch will slip to prevent possible engine damage.
In this case, stop the engine, free the cutter and then
start the operation again.
in an emergency, pull out quick release latch of shoulder
harness to detach the unit,
CAUTION
Do not allow either people or animals into the work area.
Always wear safety goggles when cutting,
Dress properly — Avoid loose clothing.
When grass or weeds have clogged the cutter head affecting
normal operation, first, stop the engine and then remove the debris.

OPERATING INSTRUCTIONS (NYLONLINE-METAL BLADES)
Your brushcutter/trimmer, has been designed and constructed to give you years of trouble-free service and relieve you of the
many back-aching tasks normally associated with grass trimming, weed control and brushcutting. Nevertheless, in common
with all other power operated tools, the Owner and/or Operator has a definite responsibility to maintain the safe working
condition of the unit as provided by the manufacturer, and to ensure also the safe operating procedures as prescribed by com-
mon sense and this manual. Please, therefore, read and understand the instructions as listed hereunder, and on Page 1, in order
to prevent accidents and possible injury.

WARNING .
1. Serious injury may result from the improper use of steel blades. Read and comply with all safety
instructions listed in this manual.
2. The eight tooth blade is designed specially to cut weed and grass. To avoid injury due to kickback
or blade fracture. DO NOT use this blade to cut brush or trees.
3. ECHO Inc. will not be responsible for the failure of cutting devices which have not been tested and
approved by ECHO for use with this unit.
SAFETY PRECAUTIONS
1. Always use the correct blade for the job as recommended.
2. Always convert 19 the handlebar configuration for extensive operations using steel blades.
3. Be careful not to hit rocks, stones, tree stumps or any foreign object which may damage the blade.
4. Do not cut into the ground to avoid dulling the blade.
5.
bent, fractured, or discolored due to overheat.
o
Always stop the engine and examine the blade after striking an obstruction. Do not operate with a blade which is blunt,
. In the event, that the blade strikes an obstruction, or is otherwise prevented from rotating in normal operation, the centri-
fugal clutch will slip to prevent engine damage. In this case, stop the engine, free and examine the blade and if in good
order, resume operation.
7. Should the brushcutter be operated for an extended period of high temperatures, the gear box may become very hot. If
too hot to touch, allow the unit to cool down, check the lubrication as per ‘Maintenance’ and continue to operate if in
order.
8. To avoid engine damage, do not run on full throttle without load.
9. Do not operate the brushcutter without the harness and debris shield correctly fitted.
10. Always inspect the work area and remove any foreign objects,
SHOULDER HARNESS
e Install the harness over the left hand shoulder and adjust
both waist and shoulder straps so that the quick release
latch rests iow on the right hand side.
e Attach the brushcutter/trimmer to the harness by means
of the short strap and the quick release latch.
® Make some practice sweeps as with a scythe and readjust
the harness as necessary for comfort and to maintain
the cutter parallel to the ground.
ATTENTION
IN CASE OF EMERGENCY, PULL
THE QUICK RELEASE LATCH TO

HEAVY WEED CUTTING
1. Install the eight (8) tooth 8" blade.
2. Observing all precautions as listed in this manual, start
the engine and using full throttle, swing the blade in an
arc as you move forward siowiy. The cutter rotates

1. install the 80 tooth hiade.
2. Proceed exactly as for weed and grass cutting.
See Fig. 17
SMALL TREES
1. The unit will effectively cut small trees up to 3 inches
in diameter using the BO tooth 8 inch diameter new
blade.
2. Before attempting to cut, ensure that the falling tree
will fall away from you, and if necessary, tie a rope to
the tree and have an assistant pull it in a safe direction.
3. De not attempt to “plunge cut”, Le, using the brush-
cutter like an axe. It is not necessary and may cause
serious damage to the brushcutter. See Fig. 18.
4, Brace your feet firmly on the ground and cut with the
left hand side of the blade.
CAUTION
1. Always cut on full throttle.
2. Never try cutting with a blunt blade.

TROUBLE SHOOTING
Poor performances can easily be corrected even by a beginner.
When the engine does not function properly check the following three (3) points first,
e Is engine compression adequate?
e Is fuel system in good condition and is enough fuel being supplied?
e Is electrical system in good condition and is spark plug operating normally?
When there is serious trouble with the unit, do not try to repair it yourself but have your distributor or dealer do it for you.
For detailed TROUBLE SHOOTING refer to tables 1 and 2. Locate the problem on the following charts and repair as nece-
