38 BKS 3835 / BKS 4040
WARNING!
When the brake operates, release the throttle lever to slow down
the engine speed. Continuous operation with the brake engaged
will generate heat from the clutch and may cause trouble.
Be sure to confirm brake operation on the daily inspection.
How to confirm:
1) Turn off the engine.
2) Holding the chain saw horizontally, release your hand from the front
handle, hit the tip of the guide bar to a stump or a piece of wood, and
confirm brake operation. Operating level varies by bar size. In case the
brake is not effective, ask our dealer inspection and repairing.
CARBURETOR ANTI-FREEZE MECHANISM
Operating chain saws in temperatures of 0 – 5°C at times of high humi-
dity may result in ice forming within the carburetor, and this in turn may
cause the output power of the engine to be reduced or for the engine to
fail to operate smoothly.
(1) Cylinder cover (2) “Sunshine” mark (3) “Snow” mark (a) Normal ope-
rating mode (b) Anti-freeze mode This product has accordingly been
designed with a ventilation hatch on the right side of the surface of the
cylinder cover to allow warm air to be supplied to the engine and to the-
reby prevent icing from occurring. Under normal circumstances the pro-
duct should be used in the normal operating mode, i.e., in the mode
which it is set at the time of shipment.
However when the possibility exists that icing may occur, the unit
should be set to operate in the anti-freeze mode before use Continuing
to use the product in the anti-freeze mode even when temperatures
have risen and returned to normal, may result in the engine failing to
start properly or in the engine failing to operate at its normal speed, and
for this reason you should always be sure to return the unit to the nor-
mal operating mode if there is no danger of icing occurring.
HOW TO SWITCH BETWEEN OPERATING MODES
(1) Cylinder cover
(2) Choke knob
(3) Icing cap
1 Flip the engine switch to turn off the engine.
2 Remove the cover to the air filter, remove the air filter, and then re-
move the choke knob from the cylinder cover.
3 Loosen the screws holding the cylinder cover in place (i.e., the three
screws on the inside and the one screw on the outside of the cover),
and then remove the cylinder cover.
4 Press with your finger down on the icing cap located on the right-
hand side of the cylinder cover to remove the icing cap.
5 Adjust the icing cap so that the “snow” mark faces upwards and then
return it to its original position in the cylinder cover.
6 Fix the cylinder cover back into its original position, and then fix all
other parts back into their proper positions.
