6. Carefully grind the cutting edge of the cutting link.
m
To avoid damages to the chain, grind as briefly as
possible and do not remove more material than
necessary. (Fig. I)
7. Grind every second cutting edge by performing
steps 5 and 6.
m
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 possi
-
ble not cut.
For this reason, a depth limit distance must always
be observed (= distance between depth limit and cut
-
ting edge). This is usually 0.5 - 0.8 mm.
5-8 mm
m
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.
m
Be sure to chamfer the leading edge of your depth
limiter. The original shape of the cutting link must
be preserved.

Warning!
Prior to any adjustment, maintenance
or service work disconnect the mains power plug!
General maintenance measures
•
Keep all safety devices, air vents and the motor
housing free of dirt and dust as far as possible.
Wipe the equipment with a clean cloth or blow it
down with compressed air at low pressure.
•
We recommend that you clean the equipment im
-
mediately after you use it.

Working instructions
m
Before commencing work, ensure the following:
•
Workplace tidied?
•
Has the chain sharpener been permanently mount
-
ed on a workbench?
•
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
m
The protective cover (17) must cover the grinding
wheel as much as possible. For this loosen the
two screw (14) and adjust the protective cover ap
-
propriately. Fig. D
m
Always keep your hands at a safe distance to the
rotating grinding wheel.
•
Do not use any damaged grinding wheels or such
that have changed their shape.
•
Start working only after the grinding wheel has
reached its maximum speed.
•
Only chains may be worked that can be put down
and guided securely.

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.
m
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).(Fig. E)
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. (Fig. F)
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 addi
-
tion, adjust the grinding depth with the setting
screw (8).(Fig. G)
5. Tighten the mounting screw (3b) → chain is fixed
in place. (Fig. H)
