FITTING THE BAR RACK

Two types of rack are available:
A - Galvanized steel rack (CZ)
B - Plastic rack with steel core (CP)
The rack height must be respected H (Fig.16 or 17 - depending
on the type of rack and pignon installed).
GENERAL IMPORTANT WARNINGS
The rack HEIGHT must be respected (Fig.16 or 17) so that
the wing never weighs on the gearmotor.
The different components of the rack must be well aligned
with each other. The pitch between the teeth must be kept
constant in the joints: use a reference template, to maintain
correct alignment and pitch.
DO NOT weld the rack pieces directly on the gate base
and DO NOT weld adjacent parts one to the other. Do
not close the free space between them (any following
adjustments would be impossible).
Keep the negative lead of the welder CLEAR OF the gear motor.
NEVER CARRY OUT ANY WELDING OPERATION
WHEN THE GEARMOTOR IS CONNECTED TO THE
MAINS.
Always protect the weldings with a zinc-based rust-
preventer spray.
In case of : ensure that the screws are fi xed
