ECHANISM
The manuals release mechanism is located on the top of
your 422 operator (see figure 2) To access the keyhole,
slide the keyhole cover in the direction of the arrow (see
figure 1). Insert the key and turn it counterclockwise
one full turn to disengage the operator's hydraulic
system. You can now move the gate leaf slowly by hand
to open or close the gate.
N
OTE
: Operating the gate leaf by hand is necessary
during power failures.
You re-engage the hydraulic system by turning the key
clockwise one full turn (or until snug). Remove the key
and slide the cover closed.
C

mechanism can damage or even break the key.

PERATOR
The FAAC recommended maintenance schedule varies
according to the frequency of use of the operators,
whether lightly used operators (once or twice an hour)
or heavily used operators (many cycles per hour).
Operators used in a humid/ salt air climate should
follow the heavy duty use schedule.
Check the oil.
To check the oil level correctly, remove the locking cap
from the operator. The operator should be at least half
full.
Note:
You will not be able to see the oil level.
Use something flexible (i.e. A piece of stranded
wire) to act as a dipstick.
If the operator is too full, it will bleed oil out the vent
hole.
Light duty use: check once per year
Heavy duty use: check every 6 mo
Change the oil.
Changing the oil requires removing the operator from
its installed position. Remove the locking cap and drain
the oil out of the hole under the cap. Refill the operator
with the proper new oil (see page 4).
Light duty use: change every 4 yr
Heavy duty use: change every 2 yr
Check the pressure settings.
Light duty use: check once per year
Heavy duty use: check every 6 mo

A qualified technician should check the entire gate
system periodically for proper operation. All reversing
devices should be functioning properly, as well as the
422 operators.
