When the log is supported along its entire length, it is cut
from the top (overbuck).
When the log is supported on one end, cut 1/3 the diameter
from the underside (underbuck).
When the log is supported on both ends, cut 1/3 the dia-
meter from the top overbuck. Then make the finished cut by
underbucking the lower 2/3 to meet the first cut.

When bucking on a slope, always stand on the uphill side of
the log. When “cutting through”, release the cutting pressure
near the end of the cut without relaxing your grip on the
chain saw handles in order to maintain complete control.
Don’t let the chain contact the ground. After completing the
cut, wait for the saw chain to stop before you move the chain
saw. Always stop the chain saw motor before moving from
tree to tree.

Maintenance and Cleaning

u

Warning! Switch off and remove plug from mains be-
fore adjusting or cleaning. The same applies when the
mains cable is damaged, cut or entangled.

If the replacement of the supply cord is necessary, this has
to be done by Bosch or an authorized Bosch service agent in
order to avoid a safety hazard.

Note:

 To ensure long and reliable service, carry out the fol-

lowing maintenance regularly.
Regulary check the chain saw for obvious defects such as
loose, dislodged or damaged saw chain and chain bar, loose
fixings and worn or damaged components.
When disassembling the saw chain, take care that the chain
is first loosened with the chain tensioning ring 

(11)

. Disas-

sembly of the chain saw without first loosening the saw chain
can damage the chain saw.
