E. SAFETY GUARD ASSEMBLY
1) In the interest of safety, it is imperative that the
unit is used with the correct guard (P/N 247209)
when using any blade or a nylon string head,
except the 24-80 tooth blade. Line cutter blade
(L): assemble as illustrated.
2) When using a saw tooth blade (optional
accessory), the correct guard must be fitted (P/N
240553).
A double shoulder harness must also be worn.
Only use blades or nylon string heads clearly
marked with a maximum speed of at least 10,500
min
-1
.
Follow the fitting instructions carefully.
N.B: Saw tooth blades (24 - 80 tooth) have a
central base diametre of 20mm and therefore
require the use of the appropriate size top flange
to ensure a correct fit. The part number is
detailed in the cutting attachment summary chart.
Use only fuel recommended by this manual.
This product is fitted with a 2-stroke engine and
therefore requires a 2-stroke petrol and oil mix.
Use unleaded petrol with a minimum octane
rating of 90.
Only use oil from sealed containers. In order to
obtain a good fuel mix, put the oil into the
container before the petrol.
The use of sub-standard petrol or oil may reduce
performance or reduce the life of certain
components.
UNLEADED PETROL
If using unleaded petrol, you must use a totally
synthetic 2-stroke engine oil, see table.
IMPORTANT
Always shake the fuel mix container thoroughly
before pouring any fuel mix.
Fuel mix properties may deteriorate with time and
should be used up within 2 months.
We recommend that you prepare fuel mix according
to your immediate requirements only. Never use fuel
mix more than 2 months old so as to avoid possible
engine damage.
WARNING
Do not smoke when re-fuelling.
Always open the fuel cap slowly, to release any
pressure build up in the tank.
Re-fuel in open spaces only, keeping away from
naked flames or sparks.
SAFE STORAGE OF FUEL
Petrol fuel mix is highly inflammable. Put out all
cigarettes, pipes and cigars before working with
fuel. Avoid spilling fuel.
Store fuel in a cool, well ventilated place, in an
approved container specifically designed for the
purpose. Never store engine with fuel in the tank
in enclosed, poorly ventilated areas, where fuel
fumes may reach an open flame, spark or pilot
light such as in a furnace, water heater, clothes
dryer etc.
Petrol fumes can cause an explosion or a fire.
Never store large amounts of fuel.
To prevent possible restarting problems avoid
running the fuel tank dry. This also helps to
extend engine life.
D. FUEL MIX
ALWAYS USE GENUINE ACCESSORIES AND
SPARE PARTS AVAILABLE FROM
AUTHORISED SERVICING DEALERS.
THE USE OF NON-ORIGINAL ACCESSORIES
AND SPARE PARTS INCREASES THE RISK OF
ACCIDENTS AND IN SUCH A CASE THE
COMPANY IS NOT LIABLE FOR DAMAGE TO
PEOPLE AND/OR THINGS.
