4 Maintenance
Clean the casing surface to avoid dust and litter.
Check the fasteners are well tightened once a month, and fasten them when necessary.
Check spring balance after the boom gate runs every 300,000 times; replace the spring with a
new one after the boom gate runs 1 million times or 12 months, to avoid spring fracture due to
overuse.
Check and replace (if necessary) wear parts every 6 months by professionals.
If the remote control distance is too close, check whether the receiver is shielded by metal
objects, or the battery of the remote control is low. The remote control distance might be
reduced if there are multiple devices of the same frequency interference in the area, or under
severe weather conditions such as rain, fog, wind and snow.
