Commissioning
Mains connection
Compare the voltage listed on the device type plate, e.g.
230 V, with the mains voltage and connect the chain
sharpener to the corresponding and properly grounded socket.
L Alternating current motor:
use a shockproof plug, mains voltage 230 V with residual
current circuit breaker (30 mA) and 10 A inert fuses.
ƒ
Use connection cable or extension cable respectively with
a cross section of at least 1,5 mm².
Switching on
Do not use any device where the switch can not be
switched on and off. Damaged switches must be repaired
or replaced immediately by the customer service.
Press “I” of the ON-OFF switch.
Switching off
To turn off the device, press “0” of the ON-OFF switch.
Working instructions
Before commencing work, ensure the following:
ƒ Workplace tidied?
ƒ Has the chain sharpener been permanently mounted on a
workbench?
ƒ You may not start to operate the machine until you have
read these operating instructions, observed all the
instructions given and installed the machine as described!
Working with the chain sharpener
The protective cover (20) must cover the grinding
wheel as much as possible.
For this loosen the two screw caps (14) and adjust the
protective cover appropriately.
Always keep your hands at a safe distance to the
rotating grinding wheel.
ƒ
Use the factory-installed grinding wheel only to sharpen
chains used in hobby applications (1/4, 3/8 hobby and
0.325 chains). (An optional grinding wheel
100 x 4.5 x 10 mm, item no. 363718, is available for
professional cutting chains.
ƒ
Check the grinding wheel for irregularities, deformation or
cracks before each use.
ƒ
Do not use any damaged grinding wheels or such that
have changed their shape.
ƒ Start working only after the grinding wheel has reached its
maximum speed.
ƒ Only chains may be worked that can be put down and
guided securely.
In any case, adhere to all safety instructions (see "Safety
instructions").
Working with the chain sharpener
Sharpening chains
Before making any settings to the device:
−
switch off the device
−
wait for the shutdown of the grinding
wheel
− pull out main plug
Grinding all cutting links
To grind the cutting edge of a cutting link, proceed as follows:
1.
Setting the grinding angle: Loosen the locking nut (7) to
turn the rotary plate to approx. 30° and retighten the
locking nut.
L
The cutting edges of the cutting links are normally
ground at an angle between 30 and 35°.
2. Loosen the mounting screw (3b) and place the cutting
chain in the guide rail (6) between the guide plates (5).
3. Fold the chain stop (4) down and pull the chain toward
the back until the cutting link to be ground rests against the
stop.
4. Pull the grinding head (13) against the cutting link for
exact alignment. Set the distance with the help of the
mounting screw (3a) so that the grinding wheel touches the
cutting link. In addition, adjust the grinding depth with the
setting screw (8).
5. Tighten the mounting screw (3b) chain is fixed in
place.
6. Carefully grind the cutting edge of the cutting link.
To avoid damages to the chain, grind as briefly as
possible and do not remove more material than necessary.
7. Grind every second cutting edge by performing steps 5
and 6.
L
Mark the first cutting link by a chalk mark or the like.
This will help you avoid grinding cutting links twice.
8. Turn the rotary table to 30° of the other side and grind
the remaining cutting edges as described above.
Setting the depth limit distance
Once all cutting edges of the cutting links have been
sharpened, your chain will be sharp but may possible not cut.
For this reason, a depth limit distance must always be
observed (= distance between depth limit and cutting edge).
This is usually 0.5 - 0.8 mm.
