Sharpening Of The Chain Blade - Hitachi CS 36DL Manual De Instrucciones

Chain catcher
○ The chain catcher is located on the power
head just below the chain to further prevent the
possibility of a broken chain striking the chain
saw user.
○ When the saw chain is cut, replace it with a
new one referring to "Installing (replacing) saw
chain".
SHARPENING OF THE CHAIN
BLADE
WARNING
To prevent accidents, always turn off the
switch and remove the storage battery
from the main body.
In addition, when using saw chains, always
wear thick gloves.
NOTE
Sharpen the saw chain and adjust the depth
gage at the central position on the guide bar,
with the saw chain attached to the main body.
When the sharpness of saw chains deteriorates,
the motor and each part of the body are burdened
and the effi ciency declines.
For optimal performance of the unit, frequent
maintenance is necessary to keep the saw chain
sharp.
1. Blade sharpening
The accessory round fi le should be held
against the chain blade so that one-fi fth of its
diameter extends above the top of the blade,
as shown in Fig. 30. Sharpen the blades by
keeping the round fi le at a 30° angle in relation
to the guide bar, as shown in Fig. 31, ensuring
that the round fi le is held straight, as shown in
Fig. 32. Ensure that all saw blades are fi led at
the same angle, or the cutting effi ciency of the
tool will be impaired. Appropriate angles for
sharpening the blades correctly are shown in
Fig. 33.

2. Adjustment of depth gage
WARNING
● Do not sand the top part of the bumper tie
strap and guard drive link, nor cause the
shape of said parts to deform.
● Adjustment of depth gages must be in line
with the predetermined dimensions and
shapes, otherwise the risk of kickback may
increase, causing an injury.
Bumper tie strap
Depth gages shall be all lined up in the same
manner because they are used to adjust depth
at the position where the cutter inlays into the
wood.
When sharpening the saw chain, be sure to
check the depth gage every two or three times.
Place a depth gage jointer on the saw chain,
leave the gage visible at the groove, and use
a fl at fi le to bevel the portion out of the depth
gage jointer. (Fig. 35) (Depth gage jointer and
fl at fi le are sold separately.)
