Maintenance Guidelines
- Clean working surfaces with aviation washing gasoline before use
- Wear sweat gloves during handling to prevent surface contamination
- Avoid organic solvents like alcohol that can corrode surfaces
- Operate in dry, clean environments only
- Clean and store in dryer or oil seal after use
- Protect from collision, scratches, rust, and environmental damage
Custom precision options available: Grade 00 with working angle deviation ≤ ±0.5″ and flatness ≤ 0.02μm
