MAINTENANCE


The following operations are to be repeated every 6 to 12 months according to the traffic intensity.
-- Unlock and remove the side doors (1:1) and (1:2).
-- Unlock the two latches (2:12) from inside and remove the hood (1:6) if necessary.
-- Remove all the dust and clean the interior of the housing, and remove any foreign body from the inside
of the cabinet (scraps, etc.).
-- Check if all screws and nuts have been tightened firmly.
-- Check if all wires are firmly connected to their respective terminal blocks.
-- Check if the arm is correctly fixed. If not, refer to paragraph [4.3 or 4.4 Installing the arm].
-- Check if the shrouds (if existing) are correctly mounted. If not, refer to paragraph [4.5 Fixing the
shrouds].
-- Check if the barrier arm is perfectly horizontal in the closed position. If needed, refer to paragraph
[4.7. Levelling the barrier arm].
-- Check the state and the tension of the V-belt referring to paragraph [5.2. Belt tension adjustment].
-- Check if the arm reopens with difficulty in case a closing movement is reversed, or if it cannot be
stopped by hand during a manoeuvre. If necessary, refer to paragraph [5.3. Safety torque limiter
adjustment].
-- Check the position of the limit switches: crankshaft plate must come flush (without pressure) with each
abutment at the end of each movement. If not, refer to paragraph [5.4].
-- Check the general state of the compression spring. Should it be replaced, follow the procedure
described in paragraph [5.5. Changing the arm model].
-- For BL52: check the wear of the balance spring fixing bolt (22:3) and replace if necessary (screw
E/0172/563, nut Z/1800/985).
-- Grease the ball straps (spherical rod ends) once a year by means of an anticorrosive multifunction
grease with a working range from -25°C to +110°C (-13°F to +250°F).
-- Check if you did not forget any tool inside the barrier.
-- Replace the hood (1:6) and lock it from inside with the two latches (2:12).
