Maintenance - EMAK GS 371 Manual De Instrucciones

LIMBING
a) Always start from the larger diameter and
move towards the tip to cut off limbs and any
secondary branches.
b) Always find the safest and most stable
position before accelerating the chainsaw. If
necessary, keep your balance by resting your
knee on the trunk itself.
c) Keep the chainsaw on the trunk so as not
to get too tired, turning it onto the left- or
right-hand side depending on the position of
the branch to cut (Fig. 20).
d) In the case of branches under tension, find a
safe position to protect yourself if they whip
back. Always start the cut from the opposite
side to the bend.
e) When lopping large diameter branches make
use of the bumper spike.
WARNING - Do not use the upper edge
of the tip of the guide bar to cross-cut;
otherwise you might risk a kickback.
BUCKING
When bucking up the trunk to desired lengths,
there is one basic rule to follow. Look to see where
the trunk is supported, and determine which way
the two halves will fall when cut.
a) If the trunk is supported at both ends, first
make a small cut at the top (1 - Fig. 21), then
complete the cut from the bottom (2 - Fig. 21).
This will avoid pinching the saw.
b) If the trunk is supported at one end or
near the center, first make a small cut from
underneath (1 - Fig. 22), then complete the cut
from the top (2 - Fig. 22).
WARNING - If the saw becomes pinched in
the trunk, stop the engine, lift the log and
change its position (Fig. 23). Never attempt to
free the saw by pulling on it.

sharpening instructions considerably
increases the risk of kickback.
CHAIN SHARPENING
The pitch of the chain (Fig. 25) is .325" or 3/8".
Sharpen the chain using protective gloves and
a round file of Ø 4.8 mm (3/16") or Ø 5.5 mm
(7/32").
WARNING - Do not fit the chain .325" on
the 3/8" pinion or vice versa.
Always sharpen the cutters only with outward
strokes observing the values given in Fig. 25.
After sharpening, the cutting links must all have
the same width and length.
WARNING - A sharp chain produces well-
defined chips. When your chain starts to
produce sawdust, it is time to sharpen.
After every 3-4 times the cutters have been
sharpened you need to check the height of the
