Operating Instruction
tree from twisting and falling in the wrong direction. Do
not cut through the hinge.
As the felling cut gets close to the hinge the tree should
begin to fall. If there is any chance that the tree may not
fall in the desired direction or it may rock back and bind
the saw chain, stop cutting before the felling back cut is
complete and use wedges of wood, plastic or aluminium
to open the cut and drop the tree along the desired line
of fall.
When the tree begins to fall remove the chain saw from
the cut, stop the motor, put the chain saw down, then use
the retreat path planned. Be alert for overhead limbs fall-
ing and watch your footing.
d) Limbing a Tree
Limbing is 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 as il-
lustrated in Figure 11. Branches under tension should be
cut from the bottom up to avoid binding the chain saw.
e) Bucking a Log
Bucking is cutting a log into lengths. It is important to
make sure your footing is fim and your weigth is evenly
distributed on both feet. When possible, the log should
be raised and supported by the use of limbs, logs or
chocks. Follow the simple directions for easy cutting.
When the log is supported along its entire length as il-
lustrated in Figure 12, it is cut from the top (over-buck).
When the log is supported on one end, as illustrated in
Figure 13, cut 1/3 the diameter from the underside (un-
derbuck). Then make the finished cut by overbucking to
meet the first cut.
When the log is supported on both ends, as illustrated
in Figure 14, cut 1/3 of that diameter from the top over-
bruck. Then make the finished cut by underbucking to
meet the first cut.
When bucking on a slope always stand on the uphill
side of the log, as illustrated in Figure 15. When “cutting
through”, to maintain complete control release the cutting
pressure near the end of the cut without relaxing your
grip on the chain saw handles. Don’t let the chain con-
tact the ground. After completing the cut, wait for the saw
chain to stop before you move the chain saw. Always
stop the motor before moving from tree to tree.
f) Spiked bumper (Fig. 16)
• Dig the spiked bumper into the log and use it as a
pivot. Cut with an arched motion to make the bar pen-
etrate the wood.
• Repeat several times if necessary, changing the point
where you plant the spiked bumper.
9. Maintenance and Servicing
Always withdraw the plug when carrying out
maintenance and servicing.
• Always remove wood shavings and oil from your chain
saw after use. Ensure in particular that the motor ven-
tilation slits for cooling the motor in the housing of the
chain saw is free (danger of overheating).
• If the saw chain is particularly dirty, e.g. in case of
gumming with resin, remove the chain and clean it.
Place the chain for a few hours in a vessel containing
chainsaw cleaner. There-after clean the chain with
clear water. If the chain is not used again immediately,
it must be treated with service spray or a customary
anticorrosion-spray.
• Only in case of use of biological oil: As some biologi-
cal oils may tend to incrustation after a time, the oiling
system should be rinsed thoroughly before storing the
chain saw for a longer period. Therefore, please fill
half of the oil reservoir (about 50 ml) with chainsaw
cleaner and close it as usually. Then switch on the
chainsaw - without bar and chain being mounted - and
keep it running until the total rinsing liquid has evapu-
rated through the oil opening of the chain saw. Before
using the chain saw again, it is absolutely necessary
to refill the oil reservoir.
• Do not store the saw outdoors or in damp and moist
areas.
• Check all the chain saw parts, in particular the chain,
bar and sprocket, of wear after every use.
• Ensure that the chain tension is correct. If the chain
is too loose, it may come off during use and lead to
injuries. The chain must be replaced immediately if it
is damaged. The cutting teeth must be at least 4 mm
long.
• Check the motor housing and power cable after every
use for damage. If there is any sign of damage, have
the chain saw checked by a specialised workshop or
the works after-sales service.
• Check the oil level and lubrication of your chain saw
after every use. Insufficient lubrication leads to dam -
age to the chain, bar and motor.
• Check how keen the chain is every time before you
use the chain saw. A blunt chain will cause overheat-
ing of the motor.
• Sharpening a saw chain requires experience and spe-
cialised knowledge. We therefore recommend to have
sharpening carried out by a specialised workshop.
10. In the case of technical problems
• The machine does not start up: Check whether the
current socket is live. Check whether the power cable
is undamaged. If neither case applies, take the chain
saw to a specialised workshop or the works after-sales
service.
•
Chain does not run:
Check position of handguard
(see ill. 7). Chain only runs if handguard brake is
released.
• Sparks fly at the motor: Motor or carbon brushes
damaged. Take the chain saw to a specialised work-
shop or the works after-sales service.
• Oil does not flow: Check the oil level. Clean the oil
flow openings in the bar (see also the corresponding
hints of “Maintenance and servicing). If this is not suc-
cessful, take the chain saw to a specialised work-shop
or the works after-sales service.
