fitting or adjusting chain.
1 Ensure chain brake lever is in disengaged position (A).
Remove retaining nuts (B) and cover.
2 Turn the adjusting screw (D) counterclockwise taking it
fully back.
3 Feed chain into bar groove ensuring correct direction of
chain (P).
4 Work the chain around sprocket and set the bar as illus-
trated, make the lower hole (F) coincide with the pin (G) of
the adjusting screw.
5 Reposition side cover. Fit spike as illustrated.
6 Lock nuts (B) finger tight.
Adjust chain tension pin by turning screw (D) so that when
lifting the chain an entire drive link is just visible.
The chain is correctly tensioned when there is no slack on
the underside of the bar, and it runs freely in bar groove.
Tighten the bar retaining nuts with the wrench, pushing bar
tip upwards.

Do not use any other type of fuel than the type recommend-
ed in this manual.
This product is equipped with a two-stroke engine and must
therefore use a mixture of lead-free gasoline (with a minimum
of 90 octanes) and fully synthetic oil for two-stroke engines,
specific for lead-free gasoline in the proportions indicated in
the table on the cover page at item (D).
IMPORTANT! Read the oil specifications on the can careful-
ly: the use of oil lacking the specifications indicated in this
manual can cause severe damage to the engine!
To obtain the best mixture, pour the oil first, followed by
the gasoline, into an approved container, shake well
(repeat the operation every time you draw any fuel from
the container).
The characteristics of the mixture are subject to aging and
may be altered in time, so we recommend mixing only the
amount strictly needed for use. If you use a mixture that is
several weeks old, this could damage the engine.
WARNING
Do not smoke when re-fuelling.
Always open the fuel cap slowly.
Re-fuel in open spaces only, keeping away from naked
flames or sparks.
Always store fuel in an approved container.
SAFE STORAGE OF FUEL
Petrol is highly inflammable. Put out all cigarettes, pipes and
cigars before working with petrol. Avoid spilling petrol. 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. Do not store large amounts of fuel.
CHAIN LUBRICATION
IMPORTANT
The service life of the bar and chain depends on good lubri-
cation. Always use chain lubricating oil of medium viscosity.
We recommend special McCulloch chain lubricating oil.
Never use waste oil for this purpose. This results in damage
to the bar, the chain and the oil pump.
Refill the chain oil tank each time the saw is refuelled.
To prevent possible restarting problems avoid running the
fuel tank dry. This also helps to extend engine life.
NOTE: Saw chain stretches during use particularly when
it is new, and it will occasionally be necessary to adjust
and tighten it. A new chain will require adjustment after
about 5 minutes of operation.
The mechanical oil pump for chain lubrication can be
adjusted.
The feed rate of the chain oil pump can be adjusted by means
of the regulating screw (A) (see details in the illustration).
6 Keep by-standers and animals out of the work area; at a
minimum distance of 10 m or twice the timber length. If
necessary, use warning signs to keep on-lookers at a dis-
tance.
Carefully survey the working site to note any hazards, eg.
roads, paths, electricity cables, dangerous trees etc. Do
not use the chainsaw if the device for stopping the chain
(safety chainbrake) does not work correctly. Never place
hands on the chain whilst the engine is running. Ensure
someone is within hearing distance in case of an accident.
If this is not possible, it is recommended that users operat-
ing chainsaws in remote areas carry an adequate first-aid kit
with them and ensure someone knows their location.
Never leave the engine running while the tool is unattend-
ed.
NEVER USE A CHAIN SAW THAT HAS FAULTY SAFE-
TY EQUIPMENT! Carry out the inspection, mainte-
nance and service routines listed in this section.
ONLY USE ORIGINAL SPARE PARTS AND ACCES-
SORIES.
