When working on a slope, stay above the cut wood.
Exercise particular caution when cutting a tensioned tree and entrust this activity to a quali fi ed lumberjack, if possible. When
cutting tensioned wood and supported on both ends, cut it from above to a depth of 1/3 of the diameter, and then fi nish the cut
from the bottom.
If the wood is supported at only one end, cut the wood from the bottom to a depth of 1/3 of the
diameter and then complete the cut by cutting from above (XIII).
This will reduce the risk of the chainsaw jamming during cutting.
Extension cords
Extension cords must be adapted for use outside con fi ned spaces.
The extension cord cores must have a cross-section at least equal to the cross-section of the core of the device’s power cord. The
rated power that the extension cord can transfer must be at least equal to the power consumed by the device.
PRODUCT MAINTENANCE AND STORAGE
Caution! Disconnect the chainsaw from the power supply before starting any activities described below. Disconnect the mains-pow-
ered chainsaws from the socket. In the case of the battery-powered chainsaws, disconnect their battery.
After each use, check the chainsaw condition paying particular attention to ventilation openings fl ow capacity.
Check the location of all chainsaw elements. Tighten all loose screw connections, if any. Check chain tension and condition. If any
chain damages are found, replace it with a new one. It is forbidden to operate the chainsaw with a damaged chain!
Too loose a chain may fall o ff the guide bar, which can lead to injury to the chainsaw operator. Moreover, the chain must also be
properly sharpened. As this requires appropriate experience and tools, it is recommended that a specialist service carries out the
sharpening. Top up the oil in the tank. Clean the chainsaw housing with soft and dry cloth. Clean the chainsaw housing of the wood
residues, oil, grease, and other contamination. Store the chainsaw disconnected from the mains in a dry, closed room.
Caution! During the chainsaw storage, a small amount of oil can escape from the chain lubrication system. This is a normal symp-
tom and does not a ff ect the oil level in the tank and is not a sign of damage.
Store the chainsaw in shaded, dry places with appropriate ventilation preventing steam condensation. The place should be
inaccessible to unauthorised persons, especially children. During storage, the guide bar and chain should always be protected
with a guard.
