ENGLISH
The operator should consider access to the tree limb and the
direction of fall. The tree branch is liable to swing towards
the tree trunk. In addition to the user bystanders, objects and
property below the branch will be at risk.
To avoid splintering, the first cut is made in an upward
direction to a maximum depth of one third the diameter of
the branch. The second cut is made downwards to meet the
first.
Logging (fig. K, L & M)
How you should cut depends on how the log is supported.
Use a saw horse whenever possible. Always start a cut with
the saw chain (6) 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 chain 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. Use clamps or straps to
secure the workpiece.
When attempting to cut a log on the ground secure the
workpiece using chocks or wedges. The user or a bystander
should not steady the log by sitting or standing on it. Ensure
the saw chain does not contact the ground.
Maintenance
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.

Saw chain and guide bar (fig. G)
After every few hours of use, remove the guide bar (7) and
the saw chain (6) and clean them thoroughly.
On reassembling, the guide bar (7) should be turned
through 180° and the sprocket nose greased via the
sprocket lubrication hole (16). This ensures an even
distribution of wear around the guide bar rails.
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 saw chains
Replacement saw chains are available through retailers or
Black & Decker service agents. Always use genuine spare
parts.
Saw chain sharpness
The saw chain cutters will blunt immediately if they touch
the ground or a nail whilst cutting.
Saw chain tension
Regularly check the saw chain tension.
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 person 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.
Mains plug replacement (U.K. & Ireland only)
If a new mains plug needs to be fitted:
Safely dispose of the old plug.
Connect the brown lead to the live terminal in the new plug.
Connect the blue lead to the neutral terminal.
Warning! No connection is to be made to the earth terminal.
Follow the fitting instructions supplied with good quality plugs.
Recommended fuse: 10 A.
Protecting the environment
Should you find one day that your tool needs
replacement, or if it is of no further use to you,
think of the protection of the environment. Black
& Decker repair agents will accept old Black &
Decker tools and ensure that they are disposed of
in an environmentally safe way.
