Owner Installation Instructions
Maintenance
Whilst your opener does not require any periodic 
maintenance, the door that it is fi tted to, does. 
Your garage door is a large, heavy, moving object 
and should be tested regularly to ensure it is in 
good condition. A poorly maintained door could 
cause fatal or serious injuries or serious damage to 
property.
To ensure a long and trouble free life for your 
opener, the following is recommended:
Monthly
Disengage the opener and manually operate 
the door: The door must be smooth to operate 
by hand. An operating force on the bottom rail 
should not exceed 150N (15kg) force.
Each month, check that the opener reverses 
when the door contacts a 40mm high object 
placed on the fl oor (AS3350). 
NOTE: If the door does not operate smoothly, call 
your installer.

Yearly
Automatic Technology suggests you contact your 
installer to perform an annual door service.
CAUTION: Frequently examine door, 
particularly cables, springs and mountings for 
signs of wear, damage or imbalance. Do not 
use if repair or adjustment is needed since 
a fault in the installation or an incorrectly 
balanced door may cause injury. (AS3350)
Adjustments should only be carried out by 
experienced persons, as this function can 
be dangerous if not performed under strict 
safety procedures.
WARNING! Failure to maintain your garage 
door may void the warranty on your garage 
door opener.
