Installation & Maintenance Tips
- Before installation, ensure the system is fully depressurised and disconnected from power if applicable.
- Inspect the mounting stem and surrounding coupling for wear, debris or damage that might affect the knob’s mechanical interface.
- Engage the knob by hand until it seats correctly, then secure using the manufacturer’s recommended torque or locking mechanism to avoid slippage or mis-alignment.
- Periodically inspect the knob for wear signs, surface abrasion, or looseness; replace if feedback becomes inconsistent or rod travel is degraded.
- Keep the knob clean from coating overspray or solvents; wipe with a soft cloth and mild cleaner as needed to maintain smooth operation.
