MAINTENANCE
Tesng
The controlled descent device should be tested every six months in most installaons. In corrosive or dusty environments, the
device should be tested more oen.
Fricon Disc
Of the operator's moving parts, the only one that could possibly wear is the fricon disc. The disc is located on the governor.
The disc is 6mm (1/4²) thick. If the disc wears so that it is less than 3mm in thickness, it will need to be replaced. (This type of
wear should not occur during the lifeme of the product.) To replace the disc, remove the selok pin that xes the governor-
hinging device to the sha. When the pin is removed, the hinging device and the fricon plate may be removed allowing
replacement of the fricon disc.
Monthly
 Check chain alignment and tension. Adjust if required
 Check PE / IR beam/s and bump edge funconality where applicable
Quarterly
 Check ghtness of xing bolts and (sprocket) grub screws. Adjust if required * refer page 6
 Check correct electrical operaon
 Check manual operaon via hand chain
 Lubricate the drive chain
 Lubricate yweight linkages and the sliding pin when it is extended from the output sha
 Ancorrosion spray should be applied to all components to prevent them from deteriorang
 Check door balance. Adjust if required
 Conduct door maintenance in accordance with door manufactures guidelines. This will include door balance
SERVICE MUST BE CARRIED OUT BY A QUALIFIED TECHNICIAN
CAUTION
DO NOT allow ancorrosion spray, grease or any other lubricang product come into contact with the fricon
disc or fricon plates!

mechanism tested
A) Ensure drive chain is aligned between sprockets.
B) Ensure drive chain is not overghtened.
C) Ensure sprockets have not been aached so that eccentric rotaon results.
D) Check for and remove any obstrucons from the shuer guides.
E) Ensure roller or ball radial thrust bearings have been used on shuer axle.
F) Increase the weight on the boom rail. And/or
G) Increase shuer reverse springing.
H) Release some of the spring tension from the shuer drum.
