Frequently Asked Questions - K 85-18 Mafell
How to install the saw blade on the Mafell K 85-18?
Unplug the tool, press the spindle lock, then loosen the center screw using the provided hex key. Remove the old blade and install the new one following the indicated rotation direction.
What type of rail to use with the K 85-18?
The saw is designed for Mafell rails with a central groove. It can also work with other grooved rails on the market, but for optimal precision, use the original rails.
How to adjust the cutting depth?
The depth adjustment knob is on the side of the saw. Loosen it, adjust the desired depth on the graduated scale, then tighten the knob. Check accuracy before cutting.
The saw does not start, what should I do?
First check that the cable is plugged in and the socket works. Make sure the anti-restart device is not activated (turn off and on again). If the problem persists, the carbon brushes may be worn.
How to maintain the carbon brushes of the K 85-18?
The carbon brushes should be checked every 100 hours of use or as soon as excessive sparks appear. Replace them with original Mafell carbon brushes by unscrewing the side caps.
Can the saw be used without a rail?
Yes, it can be used freehand for straight or miter cuts. However, for long and precise cuts, using the rail is strongly recommended.
What is the maximum cut at 45°?
The cutting depth at 45° is approximately 27 mm. This value may vary slightly depending on the blade used.
How to connect a vacuum cleaner to the saw?
Use the provided dust extraction adapter. Connect it to the saw's dust outlet and attach the vacuum hose. For optimal extraction, set the suction power to a moderate level.
Where to find spare parts for the K 85-18?
Spare parts are available from authorized Mafell dealers or on the official website. Use the model number to identify parts: K 85-18.
The blade jams during cutting, why?
This may be due to too fast feed, a dull blade, or material too hard. Reduce the feed speed, check the blade condition, and make sure the rail is clean and lubricated.
