9.1 SERVICE and MAINTENANCE
The
Brano "pro-alpha"
Garage Door Operator
is
designed for
"minimum maintenance",
and if
correctly installed, the only servicing necessary is
periodic lubrication of the wormscrew
.....Approximately every 3 months.
9.2 LUBRICATION
Very Important .......
A special lubricant is required for the Worm-shaft.
Use only :-
Brano Lubricant - GDO L 1
or
"MOBIL AVGREASE 28"
or
"MOBIL Low-Temp Lubriplate SHC-100"
or
"AERO SHELL Grease No 6"
Take Note:-
Do not use any other type of common
grease or lubricant !!
Use of the incorrect lubricant will
cause serious and permanent damage
to the operator.
Do not apply too much grease. Use
sparingly !
9.3 WEARING PARTS
Two components of the
"pro-alpha 2000"
garage door operator are
intentionally designed to
be
"sacrificial"
wearing parts,
namely the
Traveller
and the
Worm-shaft Coupling.
If either of these two components fails, it is usually an
indication that something is not as it should be with
the door system. Most likely it is an indication that the
"balance"
of the door is not correct. It may be that a
spring is stretched or broken and needs to be
replaced or some other component is unserviceable.
The
Traveller
and
Coupling
may also become
damaged if the door has suffered an impact with a car
or has been
"forced"
open. Whatever the cause, the
entire system needs to be carefully inspected.
The reasons for making these
2
components
"sacrificial"
wearing parts are:-
1
These are the easiest parts to replace!
2
These are the cheapest parts to replace!
3
Both of these items can be replaced without the
need for special tools. The repair can be
effected "on site".
4
By being designed to "fail first" they protect
more expensive and more "difficult-to-replace"
components of the operator.
IMPORTANT NOTE !
Although the
Traveller
and
Worm-shaft
Coupling
are designed to
"fail first",
they are
not intended to act as a
"back-up safety
system"
to prevent injury to persons who are
entrapped
or
struck
by the garage door.
The responsibility remains with the user of the
door to ensure that it is maintained in a
serviceable condition at all times.
Inspect the door and operator regularly for
signs of wear and tear and damage!
