Frequently Asked Questions

Q: Why did my piston crack?

A: Almost always a spring that is too strong for it, or a gear train that is not shimmed straight. Fixing the piston without fixing the cause just breaks the next one.

Q: Do I need to grease it?

A: Light grease on the piston O-ring and cylinder wall, nothing on the piston teeth beyond what the gears carry. Over-greasing causes hydraulic lock and slows the cycle.

Q: What is your return policy?

A: We offer a 30-day return policy. If you are not satisfied with your purchase, you may return it within 30 days of delivery for a full refund or exchange, provided the item is in its original condition.
