IMPORTANT NOTES ON THE CONDITION OF GARAGE DOORS

No door should be converted to automatic operation unless it is in good

working order. Before installing an automatic door operator, inspect the door

for signs of worn, damaged or missing parts and repair or replace as necessary.

Test the operation of the door to make sure that it is properly balanced.

Pay particular attention to the springs. Domestic garage door springs should

be replaced after every 10 000 operating cycles, ( or approximately 4 to 5 years

of normal usage ).
