Frequently Asked Questions - HR 850-T Cocraft
What type of blade does the Cocraft HR 850-T use?
The Cocraft HR 850-T uses a 190 mm diameter circular saw blade with a 20 mm arbor. Always use blades rated for at least 5000 rpm.
How do I adjust the cutting depth?
Loosen the depth adjustment lever, lift or lower the base plate to the desired depth using the scale, then tighten the lever securely. The maximum depth at 90° is 65 mm.
Can I cut metal with this saw?
Yes, but only soft metals like aluminum or copper using a specialized metal-cutting blade. Always clamp the workpiece and use cutting oil for best results.
How do I replace the carbon brushes?
Unplug the saw. Remove the brush holder caps on the motor housing using a screwdriver. Take out the worn brushes (minimum length 5 mm). Insert new identical brushes, replace caps, and run the saw for a few minutes to seat them.
What safety precautions should I take before using the saw?
Always wear safety goggles and hearing protection. Ensure the blade guard moves freely and snaps back. Check that the trigger lock-off works. Never operate with a dull or damaged blade.
How do I change the saw blade?
Unplug the saw. Press the spindle lock to prevent rotation. Use the supplied wrench to loosen the arbor bolt (turn clockwise on the right side). Remove the outer flange and old blade. Install new blade with teeth facing forward. Tighten bolt and release spindle lock.
What maintenance does the saw require?
Regularly clean dust from ventilation slots and the blade guard. Lubricate pivot points with light oil. Inspect the power cord for damage. Replace carbon brushes when they wear below 5 mm.
Why is the saw not cutting straight?
Check that the blade is not bent or dull. Ensure the parallel guide is properly aligned. Also verify that the base plate is square to the blade using a square. Adjust if needed.
Can I use the saw with a dust extraction system?
Yes, the saw has a dust extraction port that fits standard vacuum hoses. Connecting a vacuum improves visibility and reduces dust inhalation. Always use a Class M or H vacuum for fine dust.
What does the trigger lock-off do?
The trigger lock-off prevents accidental startup. You must press the lock-off button before squeezing the trigger. This reduces the risk of unintentional cutting injuries.
