Working In Winter; Sharpening The Saw Chain - Makita DCS 6000I Owner's And Safety Manual

Working in winter

In order to prevent carburetor icing in conditions of low temper-
ature combined with high humidity, and in order to get up to
operating temperature faster in subfreezing temperatures,
heated air can be taken from the cylinder.
At temperatures above freezing the carburetor must NOT be
fed heated air.
Failure to follow these instructions can lead to damage
to the cylinder and piston!
A
- Remove the filter cover and air filter (see "Cleaning the air
filter").
- For hot air to be inducted from the cylinder, the opening to
the cylinder (A/1) must be unblocked.
- To do this, use the carburetor screwdriver (A/2) to turn the
slide flap all the way to the right (clockwise - see arrow).
- Reinstall the air filter and filter cover.
MAINTENANCE

Sharpening the saw chain

CAUTION:
Before doing any work on the guide bar or chain, always
switch off the engine and pull the plug cap off the spark
plug (see "Replacing the spark plug"). Always wear protec-
tive gloves!
C
The chain needs sharpening when:
- The sawdust produced when sawing damp wood looks like
wood flour.
- The chain penetrates the wood only under great pressure.
- The cutting edge is visibly damaged.
- The saw is pulled to the left or right when sawing. This is
caused by uneven sharpening of the chain.
Important: Sharpen frequently, but without removing too
much metal!
Generally, 2 or 3 strokes of the file will be enough.
Have the chain resharpened at a service center when you have
already sharpened it yourself several times.

B
To get up to operating temperature faster (thus reducing wear
and tear as well as fuel consumption), you can install a cover
(B/3) inside the fan housing (B/4):
- Remove fan housing (see "Replacing the starter cable").
- Position cover (B/3) in housing as shown in Fig. B.
- Replace fan housing (when doing this, it may be necessary
to pull the starter cable lightly so that the cable pulley
catches).
IMPORTANT: At temperatures above 0° C (32° F), the cylinder
opening must be closed and the cover must be removed from
the fan housing.

Proper sharpening:
CAUTION:
Use only chains and guide bars designed for this saw
(see the Extract from the spare-parts list)!
- All cutters must be of the same length (dimension a).
Cutters with different lengths result in rough running of the
chain and can cause cracks in the chain.
- The marking (D/1) on the cutter shows the minimum cutter
length. Do not resharpen the chain when the minimum
cutter length has been reached; at this point, the chain must
be replaced (see the Extract from the spare-parts list and
"Replacing the saw chain").
- The depth of the cut is determined by the difference in
height between the depth limiter (round nose) and the
cutting edge.
- The best results are obtained with a depth-limiter depth of
.030" (0,75 mm).
CAUTION:
Excessive depth increases
the risk of kickback!
