Maintenance And Inspection - Hitachi CS 36DL Bedienungsanleitung

Precaution for cutting work
For large-scale operation or non-stop work
To protect the motor and electronics contained in this
unit, if it is exposed to high temperature, this is signaled
by a fl ashing LED light.
If you cut or push forcibly with a high load or non-stop,
the motor and electronics will heat up and the LED light
will fl ash.
NOTE
○ If the LED light fl ashes, stop using and please allow the
unit to cool suffi ciently. If you continue to use it, the unit
may sustain damage.
○ In addition, if you work non-stop, when replacing the
battery, please allow the unit to cool down for at least
15 minutes.
○ In addition, when work is interrupted, if the LED light
fl ashes when you turn the switch back on, this means
the unit has not cooled suffi ciently, so please allow
longer downtime before switching back on.
Gripping/pushing force of chain saw
Always grip the chain saw securely.
In addition, do not force the chain saw more than
necessary. When cutting, additional force exerted on
the chain saw will not accelerate the cutting speed.
This will strain the motor, impair the performance, and
damage or cause malfunction of the motor or guide bar.
Use the unit in the range where the saw chain is at a
reasonable speed.
In particular, when the saw chain stops (becomes
jammed) due to the excessive force, it may cause an
injury or failure of the unit.
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. 34.
Sharpen the blades by keeping the round fi le at a 30°
angle in relation to the guide bar, as shown in Fig. 35,
ensuring that the round fi le is held straight, as shown
in Fig. 36. 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. 37.
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. 39) (Depth
gage jointer and fl at fi le are sold separately.)
After fi ling away the depth gage, round off the front side
of the depth gage as it was. (Fig. 40)
After sharpening the saw chain, place it into chain oil to
wash off the fi lings.
If fi lings are not cleaned off , the saw chain and guide
bar will quickly wear while in use.

MAINTENANCE AND INSPECTION

After operation, perform inspection and maintenance of
each part when storing the unit.
WARNING
During maintenance and inspection, always switch off
the unit and remove the storage battery from the main
body. In addition, disconnect the power plug of the
charger from the outlet.
1. Inspection of saw chains
○ Occasionally inspect the saw chain. In the event of
any abnormality, replace it with a new one referring to
"Installing (replacing) saw chain" .
○ Inspect the chain tension and check If it is correctly
tightened.
○ Stop using the unit when the saw chain becomes blunt
and sharpen it referring to "Sharpening of the chain
blade".
○ After use, carefully lubricate the saw chain and guide
bars with oil for rust-proofi ng.
CAUTION
Wear gloves to avoid injury while using a saw chain.
2. Cleaning the side cover and brake band chamber
(Figs. 41, 42)
Clean and remove any sawdust left inside the parts.
NOTE
When cleaning the side cover, brake band chamber,
chain oil spout, and side bar, see the procedure
"Installing (replacing) saw chain" and remove the saw
chain.
3. Cleaning the chain oil spout (Fig. 43)
Before cleaning the chain oil spout, remove the side
cover and guide bar.
