SAFETY PROTECTIVE CLOTHING
Major cases of chainsaw accidents happen
when the chain hits the operator. While
working with the chainsaw, always use safety
protective approved clothing. The use of
protective clothing does not eliminate injury
risks, but it reduces the injury effects in case of
accident. Consult your trusted supplier to choose
an adequate equipment.
The clothing must be proper and not an obstacle.
Wear adherent anti-cut clothing. Anti-cut
jackets, dungarees and leggings are the ideal.
Do not wear clothes, scarves, ties or bracelets
that can stuck into woods or twigs. Tie up and
protect long hair (example with foulards, cap,
helmets, etc.)
Safety shoes or boots having skid-proof sole
and anti-piercing insert.
Wear protective helmet in places where there
can be falling objects.
Wear protective goggles or face screens!
Use protections against noises; for example
noise reduction ear guards or earplugs.
The use of protections for the ear requests
much more attention and caution, because the
perception of danger audio signals (screamings,
alarms, etc.) is limited.
Wear anti-cut gloves.
4. FITTING THE BAR AND CHAIN
WARNING - Always wear work gloves
during assembly procedures. Use only
bars and chains recommended by the
manufacturer (page 38).
- Pull the guard (Fig. 3) towards the front handle
to check that the chain brake is not on.
- Remove the bar nuts (A) and the chain cover
(B, Fig. 4).
- Remove and dispose of the cardboard spacer
placed on the chain bar stud screws (C, Fig.5).
- Take the chain tightener pawl (D, Fig. 5) to the
limit stop, by unscrewing all the chain
tightener screw (L).
- Place the bar (F, Fig. 5) onto the studs (N).
- Fit the chain (H, Fig. 6) inside the sprocket (E)
and the bar groove (M). Pay attention to the
direction of rotation of the chain (Fig. 8).
- Put down the chain cover, inserting it into its
housing and, keeping it pressed against the
bar, screw on the chain tightener screw
(L, Fig. 7) so that the pawl (D, Fig. 5) goes into
the hole (G) of the bar.
- Fit the chain cover and the relative nuts
without tightening them.
- Tension the chain by means of the tensioning
screw (L, Fig. 7).
- Hold the tip of the guide bar up and tighten
the chain cover nut securely (Fig. 9). The
tightening torque is 1,5 kgm (15 Nm). The
chain should be taut but turn freely by hand
(Fig. 10).
- The chain is tensioned correctly when it can
be pulled upwards a few millimetres (Fig. 10).
-
WARNING - Always maintain the correct
chain tension. An excessively slack chain
increases the risk of kickback and the chain may
ride out of the bar channel; these events can
cause injury the operator and damage to the
chain. An excessively slack chain will result in
rapid wear of chain, bar and sprocket. On the
contrary, an over tensioned chain will tend to
overload the motor with resulting damage. A
correctly tensioned chain provides the best
cutting characteristics, optimal safety, and
long working life of the chain. The working life
of the chain depends on correct tensioning and
correct lubrication.
5. STARTING
FUELING
WARNING: Gasoline is an extremely
flammable fuel. Use extreme caution
when handling gasoline or fuel mix. Do not
smoke or bring any fire or flame near the fuel
or the chainsaw.
· To reduce the risk of fire and burn injury,
handle fuel with care. It is highly flammable.
· Mix and store fuel in a container approved for
gasoline.
· Mix fuel outdoors where there are no sparks or
flames.
· Select bare ground, stop engine, and allow to
cool before refueling.
