8.5.2 Assembly spool (Fig. 4)
- Install the flange washer and cup washer on the spindle
shaft.
- Install the spool and tighten it.
STOP ENGINE IMMEDIATELY!
Excessive vibration of blade means that it is
not properly installed-stop engine immediately
and check blade. Blade not properly installed will
cause injury.
9 OPERATION
9.1 Fuel
Use regular grade unleaded petrol mixed with 40:1 custom
2-cycle engine oil for best results. Use mixing ratios in
Section FUEL MIXING TABLE below.
WARNING: Never use normal petrol in your
unit. This will cause permanent engine damage
and void the manufacturer's warranty for the
product. Never use a fuel mixture that has been stored
for over 90 days.
WARNING: 2-cycle lubricant must be a premium
grade oil for 2-cycle air cooled engines mixed
at a 40:1 ratio. Do not use any 2-cycle oil
product with a recommended mixing ratio of 100:1. If
insufficient lubrication is the cause of engine damage,
it voids the manufacturer's engine warranty.
9.2 Mixing fuel
Add oil to an approved fuel container followed by the petrol
to allow incoming petrol to mix with oil. Shake container to
ensure thorough mix.
WARNING: Lack of lubrication voids engine
warranty. Petrol and oil must be mixed at 40:1.
9.2.1 Recommended fuels
Some conventional kinds of petrol are now blended with
oxygenates such as alcohol or an ether compound to meet
clean air standards. The engine is designed to operate
satisfactorily with any petrol intended for automotive use
including oxygenated petrol.
10 OPERATING INSTRUCTIONS
10.1 Harness
Warning: always wear shoulder harness when
operating unit with a blade. Attach harness to
trimmer after starting unit and engine is
running at idle. Turn engine off before disconnecting
shoulder harness.
- Adjust length of shoulder strap so stringhead is parallel
to the ground as it hangs from the strap.
ENGLISH
24
A few practice swings without starting engine should
be made to determine correct balance. NOTE: Detach
the shoulder harness from the unit before starting
engine.
10.2 Starting a cold engine
Move the stop switch to "1"position.
- Give a gentle push on the primer pump repeatedly (7-
10 times) until fuel comes into the primer pump.
- Pull choke lever up to close choke.
- Pull starter handle until engine flash fires.
10.2 Change of the air filter
- Push choke lever down to open choke (excessive
cranking with choke lever will cause flooding engine
making it difficult to start).
- Pull starter handle until engine starts.
- Allow engine to warm up for a few minutes before
using.
10.3 Starting a warm engine (engine has been stopped
for no more than 15-20 minutes)
- If fuel tank was not run dry, pull starter one to three
times and should start.
10.4 To stop the engine
- Move switch to "o" position.
10.5 Trimming procedures
When properly equipped with a debris shield and
stringhead, your unit will trim unsightly weeds and tall
grass in those hard-to-reach areas - along fences, walls,
foundations and around trees. It can also be used for
scalping to remove vegetation down to the ground for
easier preparation of a garden or to clean out a particular
area.
NOTE: Even if you are careful, trimming around
foundations, brick or stone walls, curves, etc.,
will result in above-normal string wear. To
renew the wire, press the lower spool knob against
the ground with rotating trimmer.
10.5.1 Trimming / mowing (Fig. 5)
Swing trimmer with a sickle-like motion from side to side.
Do not tilt the stringhead during the procedure. Test area
to be trimmed for proper cutting height. Keep stringhead
at same level for even depth of cut.
10.5.2 Closer trimming
Position trimmer straight ahead with a slight tilt so bottom
of stringhead is above ground level and string contact
occurs at proper cutting point. Always cut away from
operator. Do not pull trimmer in towards operator.
