Troubleshooting - Black & Decker CS1835 Original Instructions Manual

Do not attempt to fell trees where the tree diameter is
u
greater than the cutting length of the chainsaw.
Cut a direction notch to determine the direction of fall.
u
Make a horizontal cut to a depth of between 1/5th and
u
1/3rd of the diameter of the tree, perpendicular to the line
of fall at the base of the tree (fig. L).
Make a second cut from above to intersect with the first
u
and make a notch of about 45°.
Make a single horizontal felling cut from the other side 25
u
mm to 50 mm above the centre of the direction notch. (fig.
M). Do not cut through to the direction notch, you could
lose control of the direction of fall.
Drive a wedge or wedges into the felling cut to open it and
u
drop the tree (fig. N).
Pruning trees
Make sure that there are no local by-laws or regulations that
would prohibit or control the pruning of the tree limbs. 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:
The length and weight of the branch to be cut.
u
Any unusual heavy limb structure or decay.
u
Surrounding trees and obstacles including overhead.
u
The wind speed and direction.
u
The branch being intertwined with other branches.
u
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, make the first cut in an upward direc-
u
tion to a maximum depth of one third the diameter of the
branch.
Make the second cut downwards to meet the first.
u
Logging (fig.O - R)
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 running and the spiked bumper (20) in contact
with the wood (fig. O).
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
u
will blunt your saw chain quickly.
When supported at both ends:
First, cut one third down to avoid splintering and second,
u
cut up to meet the first cut.
When supported at one end:
First cut one third up to avoid splintering and second, cut
u
down to prevent splintering.
(Original instructions)
When on a slope:
Always stand on the uphill side.
u
When attempting to cut a log on the ground (fig. O):
Secure the workpiece using chocks or wedges. The user
u
or a bystander should not steady the log by sitting or
standing on it. Make sure that the saw chain does not
contact the ground.
When using a saw horse (fig. Q):
This is strongly recommended whenever possible.
Position the log in a stable position. Always cut on the
u
outside of the saw horse arms. Use clamps or straps to
secure the workpiece.
Limbing (fig. R)
Removing the branches from a fallen tree. When limbing,
leave larger lower limbs to support the log off the ground.
Remove the small limbs in one cut. Branches under tension
should be cut from the bottom of the branch towards the top to
avoid binding the chain saw.
Trim limbs from opposite side keeping tree stem between you
and saw. Never make cuts with saw between your legs or
straddle the limb to be cut.

ENGLISH
Possible solution
Press the lock button.
Reset front guard
Replace fuse
Check RCD
Check mains supply
Check chain tension
Check oil tank level
Clean oil holes (21 - fig.
E) and clear the groove
around the edge of the
chainbar.
Check chain tension
Oil the guide bar
