1st CUT UNDERBUCK (1/3 DIAMETER) TO AVOID SPLINTERING

AVOID PINCHING)

When the log is supported on one end, as illustrated in Figure 14, cut 1/3
the diameter from the underside (underbuck). Then make the nished cut
by overbucking to meet the rst cut.

When the log is supported on both ends, as illustrated in Figure 15, cut
1/3 of that diameter from the top over-buck. Then make the nished cut
by underbucking to meet the rst cut.

STAND ON UPHILL SIDE WHEN CUTTING BECAUSE
LOG MAY ROLL
When bucking on a slope always stand on the uphill side of the log, as il-
lustrated in Figure 16. When “cutting through”, to maintain complete con-
trol release the cutting pressure near the end of the cut without relaxing
your grip on the chainsaw handles. Don’t let the chain contact the ground.
After completing the cut, wait for the saw chain to stop before you move
the chainsaw. Always stop the motor before moving from tree to tree.
7.6 Spiked Bumper (Fig. 17)
17
• Dig the spiked bumper into the log and use it as a pivot. Cut with an
arched motion to make the bar penetrate the wood.
• Repeat several times if necessary, changing the point where you plant
the spiked bumper.
7.7 Transporting the Chainsaw
• Before transporting the chainsaw, always remove the plug from the
power socket and slide the chain guard over the rail and chain. If sev-
eral cuts are to be performed with the chain saw, the saw must be
switched off between cuts.
• When using a vehicle to transport the machine, position it so that it can
cause no danger to persons and fasten it rmly.
8. 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.
The intake zone for motor cooling is tted with a lter (21) to protect
the inside of the unit from becoming dirty. The lter is designed in such
a way that, under normal conditions, it need only be brushed quickly
from outside to clean it. The lter can be dismantled and cleaned
externally (for instance with a blower) in the event of heavy volumes
of dust. To do so, loosen the lter cap (20) from its lock where shown
using a screwdriver (Fig. 18) and remove the lter.
• 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 ves-
sel 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 biodegradable oil: As some biodegradable oils
may tend to incrustation after a time, the oiling system should be rinsed
thoroughly before storing the chainsaw for a longer period. Therefore,
please ll half of the oil reservoir (about 1.6 oz) with chainsaw cleaner
and close it as usual. Then switch on the chainsaw - without bar and
chain being mounted - and keep it running until the total rinsing liquid
has passed through the oil opening of the chainsaw. Before using the
chainsaw again, it is absolutely necessary to rell the oil reservoir.
• Do not store the saw outdoors or in damp and moist areas.
• Check all the chainsaw 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 dam-
age. If there is any sign of damage, have the chainsaw checked by a
specialized workshop or the works after-sales service.
• Check the oil level and lubrication of your chainsaw after every use.
Insufcient lubrication leads to damage to the chain, bar and motor.
• Check how sharp the chain is every time before you use the chainsaw.
A blunt chain will cause overheating of the motor.
• Sharpening a saw chain requires experience and specialized know-
ledge. We therefore recommend to have sharpening carried out by a
specialized workshop.
9. In the Case of Technical Problems
9.1 The machine does not start up: the thermal overload switch has
triggered, wait for the cool-down period, see 4.6. Check whether the
current socket is live. Check whether the power cable is undamaged.
If neither case applies, take the chainsaw to a specialized workshop
or the works after-sales service.
