Q: What material thickness or types can the CP861 cut?
A: It is suited to cutting metal, composite, fiberglass, bolts, clamps, and similar materials up to what a 3 inch wheel can handle—within the tool’s power limits.
Q: What air supply is required?
A: Supply clean, dry air at ~90 psi (6.2 bar). Avoid exceeding this pressure to preserve tool life. Use proper hose and fittings per manufacturer guidelines.
Q: How should I maintain the CP861 for longevity?
A: Lubricate daily via inline lubricator (SAE #10 oil, ~2 drops/min). Disassemble and inspect the air motor every three months (for frequent use) and replace worn parts as needed.
