Page 19: Basic Cutting Technique
SAFETY INSTRUCTIONS • Take the utmost care when cutting through branches or logs that are in tension. A log or branch that is in tension can suddenly spring back into its natural position before or after you cut it. If you stand on the wrong side or start cutting in the wrong place it may strike you or your chain saw, so that you lose control. -
Page 20: Tree Felling Technique
SAFETY INSTRUCTIONS Cut all the way through the log from above. Avoid letting the chain touch the ground as you finish the cut. Maintain full throttle but be prepared for what might happen. If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log. - Page 21 SAFETY INSTRUCTIONS • Arrangement of branches • Weight of snow You may find you are forced to let the tree fall in its natural direction because it is impossible or dangerous to try to make it fall in the direction you first intended. Another very important factor, which does not affect the felling direction but does affect your safety, is to make sure the tree has no damaged or dead branches that might break off and...

Page 22: Freeing A Tree That Has Fallen Badly
SAFETY INSTRUCTIONS All control over the felling direction is lost if the felling hinge is too narrow or non-existent, or if the directional cuts and felling cut are badly placed. When the felling cut and directional cut are complete the tree should start to fall by itself or with the aid of a felling wedge or breaking bar. -

Page 32: Winter Use
Winter use During cold weather and under powder snow conditions, operating problems can arise due to: • Too low engine temperature. • Icing of the air filter and carburettor. Special measures are therefore often required: • Partly mask the air inlet on the starter to increase the working temperature of the engine. -
