Frequently Asked Questions - PN3800II Cotech
How do I change the blade on the Cotech PN3800II?
Unplug the saw. Press the spindle lock to prevent rotation. Use the included wrench to loosen the arbor nut (right-hand thread). Remove the outer flange and old blade. Install new blade with teeth facing forward, then reassemble.
What is the maximum cutting depth of this saw?
At 90° angle, the maximum cut depth is 64 mm. At a 45° bevel, it decreases to 45 mm.
How do I adjust the cutting depth?
Loosen the depth adjustment lever (usually near the base). Set the desired depth by aligning the scale on the base with the blade, then tighten the lever securely.
Can I make bevel cuts with the PN3800II?
Yes, the base pivots up to 45°. Loosen the bevel adjustment knob, tilt the base to the desired angle using the scale, then retighten the knob.
What size blade does the Cotech PN3800II use?
It uses a 185 mm diameter blade with a 20 mm arbor hole. Always use blades rated for at least 5000 rpm.
How do I connect a dust extractor?
The saw has a 35 mm dust port. Attach your vacuum hose directly or use an adapter. For best results, keep the dust bag or extractor connected.
What safety features does this saw have?
It includes an auto-retracting lower blade guard that covers the blade when not cutting, and a double-pole safety switch to prevent accidental start.
How often should I replace the carbon brushes?
Check carbon brushes every 50 hours of use. Replace if they are shorter than 6 mm or show signs of sparks.
What does the parallel guide do?
The parallel guide helps make straight cuts parallel to the edge of the workpiece. Clamp it to the base and adjust the width.
Where can I find replacement parts?
Replacement blades, carbon brushes, and power cords are available from Cotech or authorized dealers. Check the manual for part numbers.
