McCulloch Cabrio 246/25 cc - Manual (Page 10)

F. BLADE AND NYLON STRING HEAD ASSEMBLY
Always ensure the correct guard is assembled to
suit the kind of blade or nylon string head to be
used as well as the direction of rotation marked
on the shaft or on the guard itself.
(See section: SAFETY GUARD ASSEMBLY).
1) Assemble the nylon string head as
illustrated: a) Upper cap - b) Nylon string
head. Tighten clockwise.
2) Assemble metal blade as illustrated: a) Upper
cap with blade centering - b) Metal blade with
text facing downwards- c) Blade flange - d)
Fixed Mower gauge - e) Blade locking nut - f)
Safety split pin.
3) While tightening the blade assembly can be
held fast by inserting a wrench or the screw-
driver supplied into the cap and gearcase
holes; to do this, rotate the cap until the two
holes align.
NB. Only use blades or nylon string heads
marked with a maximum speed of at least
10.500 min
-1 .
For instructions to replace the nylon string
please refer to illustrations N1-5 in the front
of this manual.
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 leaded (4 Star) or 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.
Leaded Petrol
If using leaded petrol, the correct fuel mix is
achieved by either using 5% (20:1) of a well
known brand of 2-stroke engine oil, or else 2.5%
(40:1) of special engine oil.
Unleaded Petrol
If using unleaded petrol, you must use a totally
synthetic 2-stroke engine oil or branded 2-stroke
engine oil. In either case use 2.5% (40:1) of oil.
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.
E. SAFETY GUARD ASSEMBLY
In the interest of safety, it is imperative that the
unit is used with the correct guard which is
delivered as standard with the unit.
Only use blades or nylon string heads clearly
marked with a MAXIMUM R.P.M. SPEED of at least 10,500 min -1 .
Assemble the guard for nylon string head as
illustrated. Tighten the attachment bolts (V). Line
cutter blade (L): assemble as illustrated.
