basic safety precautions should always be
taken to reduce the risk of fire, electric
shock and personal injury.
Read this user manual carefully, observing
all of the recommended safety instructions
before, during and after use of your
chainsaw. Maintain your chainsaw in good
working order. Familiarise yourself with the
controls on your chainsaw before attempting
to operate it, but above all, be sure you know
how to stop the tool in an emergency.
Retain this user manual and all other
literature supplied for future reference.
SAFETY INSTRUCTIONS
◆ Know your chainsaw. Please read this user
manual carefully and familiarise yourself with
your chainsaw, in particular with regard to the
sawing of round wood. We strongly recommend
that first time users practice sawing logs on a
saw horse or cradle.
◆ Avoid dangerous environments. Keep your
work area clean and remove clutter. Keep the
work area well lit. We strongly recommend the
use of a sawhorse or cradle whenever possible.
Do not saw wet wood or use your
chainsaw when it is raining.
◆ Keep people away while your chainsaw is in use.
Do not allow children, other people or animals
near your chainsaw while you are using it.
◆ Maintain your chainsaw when not in use.
Do not store your chainsaw for any length of
time without first removing the saw chain and
guide bar which should be kept immersed in
oil. Store all parts of your chainsaw in a dry,
secure place out of reach of children.
We recommend you drain the oil reservoir
prior to storage.
◆ Do not force your chainsaw. It will do the job
better and more safely at the rate for which it
was intended.
Protective clothing. Wear close fitting and
protective clothing including a safety
helmet with visor/goggles, ear protectors,
safety shoes, protective bib trousers and
strong leather gloves.
◆ Do not abuse the cable. Never carry a
chainsaw by the cable or jerk it to disconnect
the plug from the socket. Keep the cable away
from heat, oil or sharp edges. Check the cable
frequently for damage.
◆ Secure your work using clamps or chocks. Be
sure that you use both hands when operating
your chainsaw.
Remove the plug from the mains before
changing the work location, adjusting,
sharpening or cleaning, changing any
accessory such as the chain, or if the cord
becomes entangled or damaged.
◆ Adjusting wrenches. Form a habit of checking
to see that adjusting wrenches are removed
from your chainsaw before starting.
◆ Only use extension cable type HO7RN-F 2 x
1mm2, as a minimum only.
◆ Stay alert. Never operate your chainsaw when
you are tired.
◆ Check damaged parts. Before further use of
your chainsaw, a guard or other part that is
damaged should be carefully checked to
determine whether it will operate properly and
perform its intended function. Check for
alignment of moving parts, binding of moving
parts, breakage of parts, mounting and any
other conditions that may affect its operation.
A guard or other part that is damaged should
be properly repaired or replaced by an
authorised service agent. Do not use your
chainsaw if the switch does not turn it on and
off.

ENGLISH
Warning! The use of an accessory or
attachment other than those recommended
in this user manual may present a risk of
personal injury.
◆ For all types of cutting, always hold the saw
firmly with both hands, with thumbs and fingers
encircling the saw handles. Do not release your
grip until your chainsaw has stopped moving.
◆ Be sure of your footing and pre-plan a safe exit
from a falling tree or branches.
◆ Use wedges to help control felling and prevent
binding the guide bar and saw chain in the cut.
◆ Keep all parts of your body and clothing away
from the saw chain when running your chainsaw.
Before you switch on make sure your chainsaw
is not contacting anything. Do not touch or try
to stop a moving saw chain with your hand.
◆ Carry your chainsaw carefully with the mains
supply disconnected and with the guide bar
and saw chain to the rear and the blade sheath
fitted.
◆ Keep your chainsaw clean. Do not allow dirt,
oil or sawdust to build up on your chainsaw.
Pay particular attention to the air inlet and
outlet slots; these must not become clogged.
Clean your chainsaw with a dry cloth but do
not use any solvents or cleaning fluids.
◆ Saw chain care. Keep the saw chain sharp and
snug on the guide bar. Ensure the saw chain
and guide bar are clean and well oiled.
Beware of kickback. Kickback is upward/
backward motion of the guide bar that
may occur when the nose of the saw chain
unexpectedly comes in contact with an
object. Hold your chainsaw firmly with
both hands when the motor is running.
Use a firm grip with thumbs and fingers
encircling the handles and watch carefully
what you cut.
Kickback can be caused by:
◆ Striking branches or other objects accidentally
with a tip of the saw while the saw chain is
moving.
◆ Striking metal, cement or any other hard
material near the wood, or buried in the wood.
◆ A dull or loose chain.
◆ Cutting above shoulder height.
◆ Lack of attention when holding or guiding
the saw while cutting.
◆ Over-reaching. Keep proper footing and
balance at all times and do not overreach.
◆ Do not try to insert into a previous cut, as this
could cause kickback. Make a fresh cut every time.
◆ We strongly recommend you do not attempt
to operate your chainsaw while in a tree, on a
ladder or on any other unstable surface. If you
decide to do so, be advised that these
positions are extremely dangerous.
◆ When cutting a branch that is under tension,
be alert for spring back so that you will not be
struck when the tension is released.
◆ Avoid cutting:
◆ Prepared timber.
◆ Into the ground.
◆ Into wire fences, nails, etc.
◆ Into small sized brush and saplings because
slender material may catch the saw chain and
be whipped towards you, or pull you off
balance.
◆ Do not use your chainsaw above shoulder height.
◆ Ensure someone is nearby (but at a safe distance)
in case of an accident.
◆ If for any reason you have to touch the chain,
make sure your chainsaw is disconnected from
the mains.
◆ The noise from this product can exceed 85 dB(A).
We therefore recommend you take appropriate
measures for the protection of hearing.
Warning symbols on your chainsaw
Read all of this manual carefully.
Do not use your chainsaw in wet
conditions or expose it to rain.
Always wear ear and eye protection.
Always remove the plug from the socket
before inspecting a damaged cable.
Be careful not to use your chainsaw if the
cable is damaged.
9
ENGLISH
To ensure continued safe operation,
check the chain tension as described
in this manual after every 10 minutes
of use, and adjust back to 3 mm as
required.
Double insulation
Your chainsaw is double insulated.
This means that all external metal parts are
electrically isolated from the power supply.
This is achieved by placing an extra insulation
barrier between the electrical and mechanical
parts. Double insulation means greater
electrical safety and obviates the necessity
of having the machine earthed.
Electrical safety
◆ Make sure your chainsaw is correct for your
supply. The voltage can be found on the rating
plate.
Fuse replacement (UK & Ireland only)
If you need to replace the fuse on your extension
cable, please note the following:
◆ The plug should be fitted with a 13 amp fuse
which is the recommended fuse for your chainsaw.
◆ Only use replacement fuses which are
approved to BS1362.
◆ When changing the fuse in your plug, always
ensure the fuse cover is refitted.
If the fuse cover is missing or damaged do not
use the plug. Note: Fuses do not give personal
protection against electric shock.
Plug replacement (UK & Ireland only)
Insertion of a detatched plug into a 13 amp
socket outlet may result in electric shock.
◆ Only fit BS1363A approved plugs fitted with
the correctly rated fuse (1).
◆ The cable wire colours, or a letter, will be
marked at the connection points of most good
quality plugs. Attach the wires to their
respective points in the plug. Brown is for
„Live“ (L) (2) and blue is for „Neutral“ (N) (4).
◆ Before replacing the top cover of the mains
plug ensure that the cable restraint (3) is
holding the outer sheath on the cable firmly
and that the two leads are correctly fixed at the
terminal screws.
Warning! Never connect live or neutral
wires to the earth pin marked „E“ or .
Note: Do not wire an extension cable
directly into your chainsaw.
Increased safety can be obtained by having a
qualified electrician install a high sensitivity
(30 mA / 30mS) circuit breaker in the house wiring.
If you do not wish to have one installed, then we
strongly recommend that the electrical power to
your chainsaw be supplied through a high
sensitivity residual current device (RCD). The RCD
is designed to provide a high degree of personal
protection against harmful electric current should
fault conditions occur.
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.
We recommend that if your mains cable is cut or
requires replacement that you return your chainsaw
to a Black & Decker service agent. When repaired,
your chainsaw will be tested for electrical safety.
We strongly recommend the use of PVC or rubber
covered plugs or connectors with your chainsaw.
◆ Disconnect the plug from the supply.
◆ Cut off the plug and dispose of immediately.

Cable connection system (UK only)
Black & Decker continually makes every effort to
achieve the highest standards in performance,
quality and reliability. We recommend the use of a
new outdoor cable connection system,
which gives additional protection against the
possibility of water or moisture entering into the
cable connector during normal use.
ENGLISH
The new connection system does not
release the operator of the tool from the
safety precautions and safe working
practices given in the manual. Particular
attention is drawn to the fact that this
connection system is ‚weather resistant‘,
but not suitable for immersion,
submersion or being subjected to water
jets. Take care to prevent the cable from
lying in or trailing through pools of water
or from splashing with hose pipes.
The following items are available:
A6615 20 m cable, socket, 13 Amp plug
A6616 20 m cable, socket, 13 Amp plug and
Cable Tidy frame
A6617 30 m cable, socket, 13 Amp plug and
Cable Tidy frame
A6613 40 m cable, socket, 13 Amp plug and
Cable Tidy reel
Existing cable systems
Your tool either comes with a cable attached
(the cat. no. ends with a C) or with a male connector
built into the tool. If you already own an outdoor
cable system with the old female connector shown
below, we recommend that you replace this
connector with the new female connector, which is
available from most major DIY outlets and from
Black & Decker service centres (cat. no. A6624S).
old female connectornew female connector
Follow the instructions supplied with the connector.
If in doubt, consult a qualified electrician.
This adaptor is only suitable for products
rated up to 500 W. It is not recommended
for use with hover mowers, rotary mowers
with grass collection, chainsaws, shredders
and blower vacs. Please contact your local
service centre if you need further advice.
Fitting your own extension cable
◆ When making your own extension cable,
fit a 13 Amp plug to one end of the cable
(see „Mains plug replacement“) and a female
connector to the other end. For wiring
instructions, see those supplied with the
female connector.
◆ A male connector (see below) is already attached
to the power supply cable on your tool. It is
non-rewireable and should not be removed. If
the connector is damaged and needs
replacement, take the tool to a Black & Decker
service centre.
female connectormale connector
Never wire an extension cable with
anything other than the female connector
supplied and a 13 Amp BS1363A
approved plug with the recommended
fuse. Never wire a male connector to the
extension cable. Never wire an extension
cable with a plug of any kind at each end
of the cable. This is extremely dangerous
and results in the pins being live, which
may cause a fatal electric shock.
Existing outdoor tools
To connect existing Black & Decker outdoor tools
to the new system, you will need an adaptor (see
below), which is available as an accessory from
most major DIY outlets and from Black & Decker
service centres (cat. no. A6623S).
Fitting the female connector
◆ To remove the cover, unscrew the fixing screw
until it is free of the nut which is located in the
hexagonal recess on the underside of the
connector. Take care not to lose the nut if it
falls out.
11
ENGLISH
The extension cable contains two wires, which are
colour coded for easy identification: brown is for
Live (L), blue is for Neutral (N). The connector is
marked ‚L‘ for Live and ‚N‘ for Neutral.
These markings are located inside the body near
the terminal screws (see below).
◆ Lift out the cable protector.
◆ Pass the cable through from the narrow end of
the cable protector.
◆ Prepare the cable ends to the strip length
shown in the illustration.
◆ Remove the cable clamp.
◆ Loosen the terminal screws until you can enter
the stripped wires between the raised washer
and the terminal.
◆ Connect the brown lead to the terminal
marked ‚L‘ and the blue lead to the terminal
marked ‚N‘. Do not fix the wires directly under
the screw head.
◆ Locate the cable and cable protector into the
body.
◆ Fit the cable clamp over the outer sheath of
the cable. Tighten the screws until fully home.
◆ Make sure that the cable clamp is firmly
holding the outer sheath of the cable and that
the two leads are correctly fixed.
◆ Place the cover onto the connector body.
◆ Securely tighten the fixing screw.
◆ Check that the cable protector is secure and
that there are no gaps between the connector
body and the cover.

◆ 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.
◆ 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.
chain for the first time. Take the new chain out
of its plastic bag and soak it in chain oil for at
least an hour before using it. Use Black & Decker
chain oil (cat. no. A6027).
12
ENGLISH
◆ 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 & C)
Always wear protective gloves when
working on your chainsaw and ensure that
the plug is not in the electrical outlet.
◆ Fit the saw chain (9) over the guide bar (8),
making sure that the cutters are the right way
round and that the slider tensioner (11) is
facing towards you (fig. B).
◆ With the tool horizontal on a stable surface,
put the bar and chain onto the bar mounting
studs (13), ensuring the chain is around the
drive sprocket (12). Make sure that the cutters
on the upper part of the guide bar face
towards the front (fig. B).
◆ Before fitting the chain cover check that the
cam (18) is in the correct position.
If necessary, press and turn the control knob (7)
clockwise to rotate the cam into the correct
position.
◆ Fit the chain cover by locating the bolt and
using the control knob (7) to tighten the chain
cover finger tight. To tension the chain, loosen
the control knob one full turn, press in firmly
and rotate clockwise. As the bar moves
forward make sure that the chain links feed
into the guide bar. When the control knob
stops rotating apply further light pressure.
Do not over-tension. Allow the control knob to
spring back to the „out“ position and rotate
further clockwise to tighten the guide bar.
Apply moderate pressure to tighten.
◆ Check the chain tension. The tension is correct
when the chain snaps back after being pulled
3 mm away from the chain bar with light force
from the middle finger and thumb.
There should be no „sag“ between the guide
bar and chain on the underside.
Note: Do not over-tension the chain as this will
lead to excessive wear and will reduce the life of
the bar and chain.
Note: When the chain is new, check the tension
frequently (after disconnecting from the mains)
during the first 2 hours of use as a new chain
stretches slightly.
USE
Let the tool work at its own pace.
Do not overload.
Filling oil into the reservoir (fig. E)
◆ Remove the oil cap (3) and fill the reservoir with
the recommended chain oil. You can see the oil
level in the indicator slot (4). Refit the oil cap.
◆ Periodically switch off and check the oil in the
indicator; if it is less than a quarter full,
disconnect your chainsaw from the mains and
refill with the correct oil.
Auto-stop chainbrake (fig. F & G)
This tool is fitted with an auto-stop chainbrake which
will stop the chain within 150 ms each time you
release the rear trigger, or if kickback should occur.
This brake should be tested before every use.
How to set the chainbrake
◆ Make sure that the tool is disconnected from
the mains supply.
◆ Pull the front guard (5) back into the „set“
position .
The tool is now ready to use.
How the anti-kickback chainbrake works
In the event of kickback, your left hand comes in
contact with the front guard, pushing it backwards,
and stops the tool within 150 ms.
How the inertia activated chainbrake works
The chainbrake is activated when the front hand
guard is pushed forward, either manually, by the
back of the users hand or by its own weight. The
advantage of the inertia brake is that it is activated
by a severe kickback, eg. when the chain hits metal,
even if the users hand does not contact the front
guard, ie. when the saw is in the felling position.
13
ENGLISH
How to test the anti-kickback chainbrake
◆ Grip the tool firmly in both hands on a firm
surface - make sure the chain is clear of the
ground and switch on (see „How to switch your
chainsaw on“).
◆ Rotate your left hand forward around the front
handle so that the back of your hand comes in
contact with the front guard and pushes it
backwards (fig. G). The chain should stop
within a few fractions of a second.
To reset after the operation of the chainbrake
◆ Follow the instructions for setting the chainbrake.
Notes:
◆ It will not be possible to switch the tool on if
the front guard is not in the „set“ position.
◆ Avoid re-starting the tool until you hear the
motor come to a complete rest.
◆ If the chain does not come to rest immediately
then this indicates that it needs tensioning
(see „Fitting the guide bar and chain“).
How to switch the tool on (fig. A)
◆ Grip your chainsaw firmly with both hands.
Push the lock-off button (2) forward and then
push the on/off switch (1) to start.
◆ When the motor starts, remove your thumb
from the lock button and grip the handle firmly.
Do not force the tool - allow it to do the work.
It will do a better and safer job at the speed for
which it is designed. Excessive force will stretch
the chain.
If the saw chain or bar becomes jammed:
◆ Switch the tool off.
◆ Disconnect the tool from the mains supply.
◆ Open the cut with wedges to relieve the strain
on the guide bar. Do not try to wrench the saw
free. Start a fresh cut.
Felling (fig. H - J)
◆ Pre-plan a safe exit from falling trees or branches.
◆ Cut one third of the diameter of the tree (Fig. H).
Then cut down from above to make a notch of
about 45°. This way you will avoid pinching the
saw.
14
◆ Make a single felling cut from the other side
but stop before you cut through to the notch
(fig. I).
◆ Drive a wedge or wedges into the felling cut to
open it and drop the tree (fig. J).
Logging (fig. K - M)
How you should cut depends on how the log is
supported. Use a saw horse whenever possible.
Always start a cut with the chain running and the
spiked bumper (17) in contact with the wood (fig. K).
To complete the cut use a pivoting action of the
spiked bumper against the wood.
When supported along its whole length
◆ Make a downward cut, but avoid cutting the
earth as this will blunt your saw quickly.
When supported at both ends
◆ First, cut one third down to avoid splintering
and second, cut again to meet the first cut.
When supported at one end
◆ First, cut one third up to avoid splintering and
second, cut down to prevent splintering.
When on a slope (fig. L)
◆ Always stand on the uphill side.
When using a saw horse (fig. M)
This is strongly recommended whenever possible.
◆ Position the log in a stable position. Always cut
on the outside of the saw horse arms.
MAINTENANCE (fig. N)
Regular maintenance ensures a long effective life
for the tool. We recommend you make the
following checks on a regular basis.
Oil level
The level in the reservoir should not be allowed to
fall below a quarter full.
Chain and guide bar
◆ After every few hours of use, remove the guide
bar and chain and clean thoroughly.
◆ Ensure the hole between the tensioning/oil
hole (18) and the bar groove is clear.
ENGLISH
◆ On reassembling, the guide bar should be
turned through 180° and the sprocket nose
greased via the sprocket lubrication hole (19).
This ensures an even distribution of wear
around the guide bar rails.
◆ To turn the guide bar through 180°, remove
the small screw from the slider and re-fasten to
the opposite side of the bar.
Saw chain sharpening
If you are to get the best possible performance
from the tool it is important to keep the teeth of
the saw chain sharp. Guidance for this procedure
is found on the sharpener package. For this purpose
we recommend the purchase of the Black & Decker
saw chain sharpening kit (available from
Black & Decker service agents and selected dealers).
Replacing worn out chains
Replacement chains are available through retailers
or Black & Decker service agents. Always use
genuine spare parts.
Saw chain sharpness
The cutters will blunt immediately if they touch the
ground or a nail whilst cutting.
Saw chain tension
◆ Regularly check the chain tension.
Oil level
◆ Top up if low.
What to do if your chainsaw needs repair
Your chainsaw is in accordance with the relevant
safety requirements. Repairs should only be
carried out by a qualified persons using original
spare parts, otherwise this may result in considerable
danger to the user. We recommend you keep this
user manual in a safe place.
