Maintenance work should be carried out when the machine is above 0˚C and when all moving parts have been stopped. It should only be carried out by personnel who are deemed competent to do so i.e. site maintenance engineers.
Daily checks:
- Check belt for wear or damage
- Verify the function of belt take-up and limit switches
- Check the operation of all belt fault switches
- Inspect the function of covers and baffles
- Check overdrive
- Inspect drum, rail, and belt guide plastics
Monthly checks:
- Examine auxiliary drive sprockets for wear
- Check auxiliary drive and drive motor oil levels
- Inspect drive motor bearings for noise
- Ensure rollers, sprockets, and bearings are securely attached
- Check the header tank and gearboxes for water in the oil
- Grease the seal at the top of the main drive gearbox
Other maintenance tasks:
- Check and clean spray nozzles (for machines with water defrosting)
- Inspect fan balance, bearings, and housing
- Examine electrical equipment for moisture damage
- Check lights and wiring
- Inspect junction boxes for leaks
- Verify control panel filter pads are clear
- Test operation of emergency sensors and stops
Lubrication:
- Regular lubrication of various components like gearboxes and bearings according to the provided schedule.
- Check gearbox oil levels every month.
-To drain oil, remove the lowest drain plug and filler plug. Drain oil and flush with oil of a similar grade. Drain and flush as above. Replace the drain plug and ensure the top of the gearbox is vented, refill directly to the top of the gearbox or through the expansion tank. With the gearbox full to the top, replace the vent plug and fill the expansion tank to 75%. Replace the fill plug in the expansion tank.
(NOTE: All charging must be done with the gearbox at room temperature).
Air balancing:
- Adjust airflow and pressure zones within the enclosure to minimize air loss and prevent warm air ingress.
It is important to follow these procedures to maintain the machine’s performance and fulfil warranty conditions.
(NOTE: All charging must be done with the gearbox at room temperature).
