Before operating the tool, make sure that:
• Your workplace is uncluttered.
• The chain sharpener is correctly and permanently mounted on a workbench.
• You have read and understand all safety and operating instructions.
The protective cover (18) must cover the grinding wheel as much as possible.
Always keep your hands at a safe distance from the rotating grinding wheel.
• Use the grinding wheel already provided by the manufacturer only to sharpen 1/4", 0.325", 3/8" saw chains.
• Do not use damaged grinding wheels or wheels that have lost their shape.
• Start working only after the grinding wheel has reached its maximum speed.
• Only work on chains that can be fitted and guided securely through the chain guide.
Sharpening chains
Always switch the appliance off and unplug the power plug before making any adjustments.
Grinding cutting links (Img. A - C)
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. 300 and retighten the locking nut.
The cutting edges of the cutting links are normally ground at an angle between 300 and 350.
2. Loosen the mounting screw (3b) and place the cutting chain in the guide rail (6) between the guide plates (5).
3. Hold 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 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 outer 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 using a chalk mark or a similar method. This will help you avoid grinding cutting links twice.
8. Turn the rotary plate 300 to the other side and grind the remaining cutting edges as described above.
Setting the depth limit spacing
Once the chain has been fully sharpened, make sure that the depth limit spacing is maintained (distance between depth limit and cutting edge). This is usually
0.5 - 0.8 mm.
A large depth limit spacing presents a high 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.
Make sure you trim the front end of the depth limit. The original shape of the cutting link must be preserved.
