Pruning should only be undertaken by experienced users
there is an increased risk of the saw chain pinching and
kick back.
Before pruning consideration should be given to conditions
affecting the direction of fall including:
f
The length and weight of the branch to be cut.
f
Any unusual heavy limb structure or decay.
f
Surrounding trees and obstacles including overhead
f
The wind speed and direction.
f
The branch being intertwined with other branches.
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. L, M y N)
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. L). To complete the cut use
a pivoting action of the spiked bumper against the wood.
When supported along its whole length:
f
Make a downward cut, but avoid cutting the earth as
this will blunt your saw chain quickly.
When supported at both ends:
f
First, cut one third down to avoid splintering and
second, cut again to meet the first cut,
When supported at one end:
f
irst cut one third up to avoid splintering and second,
cut down to prevent splintering.
When on a slope (Fig. M):
f
Colóquese siempre cuesta arriba.
Always stand on the uphill side.
When using a saw horse (Fig. N):
This is strongly recommended whenever possible.
f
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 si tting or standing
on it. Ensure the saw chain does not contact the ground.
MAINTENANCE
Keep guards, air vents and the motor housing as clear as
possible of dust and dirt. Wipe with a clean cloth and blow
through with a low-pressure air supply. Excessive build-up
of metal dust can cause tracking of electrical current from
the internal parts to exposed metal parts.
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. H)
f
After every few hours of use, remove the guide bar (7)
and the saw chain (6) and clean them thoroughly.
f
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.
Replacing worn out saw chains
Replacement saw chains are av ailable 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.
Important! To assure product SAFETY and
RELIABILITY, repairs, maintenance and adjustment
(other than those listed in this manual) should be
performed by authorized service centers or other qualified
service personnel, always using identical replacement
parts.
