Frequently Asked Questions - HC85 Cocraft

What type of chainsaw chains can I sharpen with the Cocraft HC85?

The HC85 is compatible with chain pitches of 1/4", 0.325", 3/8", and 0.404". Always verify your chain pitch before use.

How do I set the correct filing angle?

Loosen the vice locking knob at the bottom, rotate the vice to the desired angle (typically 30° or 35° depending on your chain), then retighten the knob. Refer to your chain manufacturer's recommendation.

Do I need to use safety glasses?

Yes, always wear safety glasses and ear protection when operating the sharpener. The grinding process produces sparks and noise.

How do I replace the grinding wheel?

Unplug the machine, raise the grinding wheel arm, remove the guard screws, unscrew the flange nut anticlockwise, replace the wheel with a new one (108 mm outer, 23 mm bore, 3.2 mm thick), tighten the flange nut by hand, and reattach the guard. Never overtighten as it may damage the wheel.

Why does my grinding wheel vibrate?

Vibration may indicate an unbalanced or damaged wheel. Stop the machine immediately and inspect the wheel. If damaged, replace it. Ensure the wheel is centered and the flanges are clean.

How often should I adjust the raker clearance?

After sharpening the chain 2 to 4 times, check the raker height. Use a flat file and depth gauge to file down the rakers to maintain proper clearance (typically 0.5-0.7 mm). Consult your chain manual for exact specifications.

Can I use a different grinding wheel?

Only use grinding wheels recommended by the manufacturer with the correct diameter (108 mm), bore (23 mm), and thickness (3.2 mm) rated for at least 4800 RPM. Using incorrect wheels can be hazardous.

What should I do if the chain gets caught in the vice?

Unplug the machine before adjusting. Loosen the vice locking lever slightly, reposition the chain, and retighten. Ensure the chain stop is properly engaged.

How do I clean the sharpener?

Keep the sharpener free of dust and metal filings by wiping with a dry cloth or using a soft brush. Do not use flammable solvents. Store in a dry place out of children's reach.

The chain is not sharpening evenly. What could be wrong?

Check that the filing angle is set correctly for both sides of the chain. Ensure the depth stop is adjusted properly and that the chain is securely clamped. Also verify the grinding wheel is not worn or damaged.

Installation, mounting

1. Position the sharpener on the workbench in such a way that the two feet on the bottom rest against the lip of the workbench and the vice locking knob (2) is accessible. Bear in mind that work area needs to be well-lit for adjusting and using the sharpener.
2. Bolt the chainsaw sharpener to the workbench using the two holes in the base.

Fitting and replacing the grinding wheel

1. Raise the grinding wheel arm (4) to maximum elevation.
2. Undo the two screws holding the grinding wheel guard (3) in place and remove it, keep the screws safe.
3. Unscrew the flange nut (11) holding the grinding wheel (5) in place and remove both the lock nut and grinding wheel. (turn the lock nut anticlockwise to undo it).
4. Insert a new grinding wheel onto the spindle making sure that it is centred and that the flanges are clean and flat. Tighten the flange nut (11) by hand, if the flanges are tightened too much the grinding wheel could become damaged, which could lead to the operator being seriously injured if the wheel shatters during use. Use only recommended grinding wheels according to the specifications. Make sure that the flange nut (11) is the right way round; the cupped side should be facing the grinding wheel.
5. Screw the grinding wheel guard (3) back on.
6. Always test newly attached wheels by starting the motor and letting the wheel spin for a minute or two before starting work. Whilst testing the wheel you should remain at a safe distance and not allow anyone else to come close in case the disc shatters.

If you notice that the wheel vibrates when turned on or during operation, the machine should be stopped immediately and the wheel should be inspected.

Warning:

Never try to stop the grinding wheel with your hand even if you are wearing safety gloves. Contact with a grinding wheel spinning at high speed can cause burns and scrapes.

Adjustment

Warning:

All adjustments should be made when the machine is turned off and unplugged.

1. Check which type of chain you have, set the correct filing angle (most chains have a filing angle of 30^ or 35^ ), tighten the locking knob (2) on the bottom.

6. Lower the grinding wheel arm (4) and test if the setting is correct before starting the motor.
7. The sharpener is now set up.

Use

Warning:

Never try to stop the grinding wheel with your hand even if you are wearing safety gloves.

Contact with a grinding wheel spinning at high speed can cause burns and scrapes.

1. Clean the chain thoroughly before sharpening, do not use a flammable solvent. Allow the chain to dry before starting to sharpen it.
2. Lay the chain in the vice (9), lower the chain stop (8) against the back of the link and stretch the chain backwards toward the chain stop, tighten the vice locking lever (10) so that the chain is locked in place.
3. Lower the grinding wheel arm (4) and test if the setting is correct before starting the motor. Remember to put your safety glasses on before starting the motor!
4. Push the green start button to start the motor and let it come up to speed.
5. Carefully lower the grinding wheel arm and test it on one of the links, carefully raise the arm again, check the results, turn the motor off and adjust if necessary. If the settings are correct you can continue sharpening. Bear in mind that best results are achieved if the contact between the grinding wheel and the chain link occurs gradually and gently, do not grind the same link for too long.
6. Fully elevate the grinding wheel arm, undo the vice locking lever (10) and move the chain forwards to the next link (which is facing the same way) stretch the chain backwards against the chain stop (8), tighten the vice locking lever (10).
7. Take your hand off the chain and continue sharpening.
8. Continue in the same way with all the cutting links that are facing the same way.
9. Undo the locking knob (2) on the bottom, turn the vice (9) and set the correct filing angle for the rest of the cutting links that face the other way, tighten the locking knob (2) on the bottom. Continue until the whole chain is sharpened. Remember to unplug the machine after use.
10. Discard the chain if the cutting edge is ground down to under 3 mm.

Raker Clearance, Setting the Cutting Depth of the Chain

It is the relationship between the cutting edge of the link and the height of the raker that determines how much material is removed by the chain. It is therefore very important that this relationship is maintained for the life of the chain. The correct clearance is very important both for safety and optimum stock removal.

If the chain has been grinded 2 to 4 times (depending upon how much material has been ground away) the rakers might need to be filed down to maintain the same raker clearance (and depth of cut). Use a flat file and a file guide/depth gauge to file the rakers.

If you do not have a file guide for setting the raker clearance you can use a flat file and file two strokes off each of the rakers as shown in the figure.

Care and Maintenance

• Keep the sharpener free of dust and metal filings.
• Replace the grinding wheel when it is worn down to ∅ 75 mm.
• Store the sharpener in a dry place out of children's reach.
