ENGLISH
Checking and adjusting the chain tension (fig. I)
Before use and after every 10 minutes of use, you must check
the chain tension.
Disconnect the tool from the mains supply
u
Lightly pull on the chain (5) as shown (inset fig. I). The ten-
u
sion is correct when the chain (5) snaps back after being
pulled 3 mm away from the guide bar (4). There should be
no "sag" between the guide bar (4) and the chain (5) on
the underside.
Note: Do not over-tension the chain as this will lead to
excessive wear and will reduce the life of the guide bar and
the chain.
Note: When the chain is new, check the tension frequently
(after disconnecting from the mains) during the first 2 hours of
use because a new chain stretches slightly.
To increase the tension (fig. H)
Turn the chain adjust locking knob (7) counterclockwise.
u
Tension the chain using the chain tension adjusting screw
u
(8), turn clockwise to tighten.
Tighten the chain adjust locking knob (7).
u
Use
Warning! Let the tool work at its own pace. Do not overload.
Filling the oil reservoir (fig. K)
Remove the oil cap (12) and fill the reservoir with the
u
recommended chain oil. You can see the oil level in the oil
level indicator (13). Refit the oil cap (12).
Periodically switch off and check the oil level indicator
u
(13); if it is less than a quarter full, disconnect your chain-
saw from the mains supply and refill with the correct oil.
This chainsaw is equipped with an automatic oiling system
that keeps the saw chain and guide bar constantly lubricated.
We recommend that you use only BLACK+DECKER 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 and create additional
risks.
Never use waste oil, thick oil or very thin sewing machine
oil. These may damage your chainsaw .Only use the correct
grade of oil (cat. no. A6023-QZ).
The chain saw will automatically feed oil to the chain dur-
u
ing use.
Switching on
Note: It will not be possible to switch the tool on if the front
guard/chain brake assembly is not in the "set" position.
Grip your chainsaw firmly with both hands. Push the lock-
u
off button (2) and then push the on/off switch (1) to start.
When the motor starts, remove your thumb from the lock
u
button (2) and grip the handle firmly.
Do not force the tool, allow the tool 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 saw chain (5).
How to set the chain brake (fig. A)
Make sure that the tool is disconnected from the mains
u
supply.
Pull the front guard/chain brake assembly (3) back into the
u
"set" (fig. A) position.

(Original instructions)
The tool is now ready to use.
u
How the anti-kickback chain brake works
In the event of kickback, your left hand comes in contact with
the front guard, pushing it forwards, toward the workpiece,
and stops the tool within a few fractions of a second.
How to test the anti-kickback chain brake (fig. A)
Always check that the kickback brake operates correctly
u
before use.
Grip the tool firmly in both hands on a firm surface make
u
sure the saw chain (5) is clear of the ground and switch on
(see" How to switch the chainsaw on").
Rotate your left hand forward around the front handle so
u
that the back of your hand comes in contact with the front
guard/chain brake assembly (3) and push it forwards,
toward the workpiece (fig. A). The saw chain (5) should
stop within a few fractions of a second.
To reset after the operation of the front guard/chain brake
assembly (3) follow the instructions for "How to set the chain
brake".
Note: Avoid re-starting the tool until you hear the motor come
to a complete rest.
Note: If chain brake in malfunctioning take the product to an
approved BLACK+DECKER service centre.
If the saw chain (5) or guide bar (4) becomes jammed
Switch the tool off.
u
Disconnect the tool from the mains supply.
u
Open the cut with wedges to relieve the strain on the
u
guide bar (4). Do not try to wrench the chainsaw free.
Start a fresh cut.
u
Felling (fig. L - R)
Inexperienced users should not attempt to fell trees. The user
may suffer injury or cause damage to property as a result of
failure to control the direction of fall, the tree may splinter or
damaged/dead branches may fall during cutting.
The safe distance between a tree to be felled and bystanders,
buildings and other objects is at least 2 1/2 times the height of
the tree. Any bystander, building or object within this distance
is at risk from being struck by the tree when felled.
Before attempting to fell a tree:
Make sure that there are no local by-laws or regulations
u
that would prohibit or control the felling of the tree.
Consider all conditions that may affect the direction of fall,
u
including:
The intended direction of fall.
u
The natural lean of the tree.
u
Any unusual heavy limb structure or decay.
u
Surrounding trees and obstacles including overhead
u
lines and underground drains.
The wind speed and direction.
u
Pre-plan a safe exit from falling trees or branches. Make sure
that the exit route is clear of obstacles that would prevent or
hinder movement. Remember that wet grass and freshly cut
bark is slippery.
