Additional Safety Instructions - Black+Decker GK1740 Manual De Instrucciones

Avoid cutting:
f Prepared timber.
f Into the ground.
f Into wire fences, nails. etc.
f Into small sized brush and saplings because slender
material may catch the saw chain and be whipped
towards you, or pull you off balance.
f Do not use your chainsaw above shoulder height.
f Ensure someone is nearby (but at a safe distance) in
case of an accident.
f If for any reason you have to touch the saw chain,
make sure your chainsaw is disconnected from the
mains.
f The noise from this product can exceed 85 dB(A).
f We therefore recommend you take appropriate
measures for the protection of hearing.

ADDITIONAL SAFETY INSTRUCTIONS

f This appliance is not intended for use by young or
infirm persons without supervision. Children must be
supervised to ensure they do not play with the
appliance.
f If the supply cord is damaged, it must be replaced by
the manufacturer or an authorised BLACK+DECKER
Service Centre in order to avoid a hazard.
Guard against electric shock.
f Prevent body contact with earthed or grounded
surfaces (e.g. metal railings, lamp-posts etc.). Electric
safety can be further improved by using a high-
sensitivity (30 mA/30mS) Residual Current Device
(RCD).
Warning! The use of an RCD or other circuit breaker
unit does not release the operator of your chainsaw from
the safety instructions and safe working practices given in
this user manual.
ASSEMBLY
Oiling the chain (Fig. B)
You must do this whenever you use a new chain (6) for the
first time. Take the new chain (6) out of its plastic bag and
soak it in chain oil for at least an hour before using it. Use
BLACK+DECKER chain oil.
We recommend that you use only one brand of oil during
the lifetime of your chainsaw because mixtures of different
oils could lead to the oil becoming degraded, which can
drastically shorten the lifetime of the saw chain.
Never use waste oil, thick oil or very thin sewing machine
oil. These may damage your chainsaw.
Fitting the guide bar and chain (Fig. B - G)
Warning! Always wear protective gloves when
working on your chainsaw.
f Place the chainsaw onto a stable surface. Loosen and
remove the chain cover knob (9) (Fig. B).
f Set the front guard to position
f Remove the chain cover assembly (10).
f Place the chain (6) over the guide bar (7), making
sure that the saw chain cutters on the upper part of
the guide bar (7) face towards the front (Fig. C).
f Guide the chain (6) around the guide bar (7) and pull
it to create a loop to one side at the rear end of the
guide bar (7).
f Place the chain (6 ) and guide bar (7) onto the
chainsaw. Guide the chain (6) around the drive
sprocket (12). Place the guide bar (7) onto the studs
(13). Make sure that the sliding nut peg (14) locates
into the te nsioning hole (15) (Fig. F).
f Make sure that the chain brak e assembly (4) is in the
set position before refitting (Fig. D).
f Place the chain cover assembly (10)
onto the chainsaw.
f Fit the chain cover knob (9) and tighten it finger tight.
f Turn the chain tension adjustment screw (5)
(Fig.F) clockwise until the chain (6) is tight. Make sure
that the chain (6) is snug around the guide bar (7).
Do not overtighten.
f Tighten the chain cover knob (9).
Checking and adjusting the chain tension
(Fig. F y H)
f Before use and after every 10 minutes of use, you
must check the chain tension.
f Lightly pull on the chain (6) as shown (inset Fig.H).
The tension is correct when the chain (6) snaps back
after being pulled 3 mm away from the guide bar (7).
There should be no "sag" between the guide bar (7)
and chain (6) on the underside.
Note: Do not over-tension the chain (6) as this will lead to
excessive wear and will reduce the life of the guide bar (7)
and the chain (6).
Note: When the chain (6) is new, check the tension
frequently (after disconnecting from the mains) during the
first 2 hours of use as a new chain (6) stretches slightly.
To increase the tension:
f Turn the chain tension adjustment screw (5a)
clockwise.
Filling the oil reservoir (Fig. G)
f Remove the oil cap (3) and fill the reservoir with the
recommended chain oil. You cansee the oil level in
the oil levelindicator (11). Refit the oil cap (3).
f Periodically switch off and che ck the oil level
indicator (11); if it is less than a quarter full,disconnect
your chainsaw from the mains and refill with the
correct oil.
