When felling trees, follow the procedures below:
1. Cut a scarf as close to the ground as possible. First make the
horizontal cut to a depth of 1/5 -1/3 of the trunk diameter. Do not
make the scarf too large. Then make the diagonal cut.
2. Make the back cut a little higher than the base cut of the scarf.
The back cut must be exactly horizontal. Leave approximately 1/10
of the trunk diameter between the back cut and the scarf. The wood
fibers in the uncut trunk portion act as a hinge. Insert wedges into
the back cut in time.
Carrying tool
Before carrying the tool, always apply the chain brake and remove
the battery packs from the tool. Then attach the guide bar cover.
Sharpening the saw chain
Sharpen the saw chain when:
Mealy sawdust is produced when damp wood is cut;
The chain penetrates the wood with difficulty, even when heavy pressure is applied;
The cutting edge is obviously damaged;
The saw pulls to the left or right in the wood.
(caused by uneven sharpening of the saw chain or damage to one side only)
Sharpen the saw chain frequently but a little each time. Two or three strokes with a file are usually
sufficient for routine resharpening. When the saw chain has been resharpened several times, have it
sharpened in our authorized service center.
Cleaning the guide bar
Chips and sawdust will build up in the guide bar groove. They may dog the bar groove and impair the oil
flow. Clean out the chips and sawdust every time when you sharpen or replace the saw chain.
Cleaning the sprocket cover
Chips and saw dust will accumulate inside of the sprocket cover. Remove the sprocket cover and saw
chain from the tool then clean the chips and saw dust.
