Working With The Chain Sharpener; Maintenance And Care - ATIKA KSG 220 A Notice Originale

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.
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)
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.
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.
chain is fixed in
14
A depth limit distance that is too great represents a risk of
kickback.
For this purpose, you must check the distance according to the
specifications of your chain and file it off with a file if
necessary.
Be sure to chamfer the leading edge of your depth limiter.
The original shape of the cutting link must be preserved.

Maintenance and Care

Before each maintenance and cleaning work:
- switch off device
- wait for the shutdown of the grinding wheel
- pull out main plug
Replacing the grinding wheel
Do not use any damaged grinding wheels or such that
have changed their shape.
Do not use any grinding wheels which do not comply with
the indicated characteristics of this instruction manual.
Replacing the grinding wheel
1. Loosen the screw caps (14) and remove the
protective cover (20).
2. , Loosen the nut (21) on both sides of the cover
(10). Remove the cover.
3. To lock the grinding wheel, insert a screw driver or
mandrel (4 mm dia.) in the hole provided.
4. Loosen the nut (15).
Right-hand thread
5. , Remove the nut, the front flange (16), the
grinding wheel (9) and the rear flange (16).
6. Clean the flanges.
7. Reassembly is done in the opposite sequence.
For maintaining and cleaning, removed security devices must
unconditionally be mounted properly and proved again.
Use only original parts. Other parts can result in unexpected
damages and injuries.
Note the following to keep your chain sharpener
functioning:
Clean and oil all moving parts regularly (except for the
drive system).
