8.2.2. PROCEDURE FOR A SOLUTION 3 OR 4

The procedure is almost identical for a solution 3 or 4 gate.

However, in this case the stop is reversed and the lever movement is therefore counter-clockwise. It is therefore more

convenient to make this movement with the right hand and to accompany the movement of the boom with the left hand.

8.3. MAINTENANCE

MAINTENANCE OPERATIONS MUST BE CARRIED OUT IN COMPLIANCE WITH THE SAFETY WARNINGS STATED IN CHAPTER 1.

Unlock and remove door ( Rep. 5, Fig. 1, page 9) without damaging the ground wire that connects it to the housing.

Switch off the circuit breaker ( Rep. 24, Fig. 1, page 9).

If necessary, remove the cover ( Rep. 2, Fig. 1, page 9) without damaging the ground wire that connects it to the housing.

After the first 1000 operations, check the adjustment of the analog sensor ( Chap. 7.6, page 33).

Every 6 to 12 months, depending on the traffic level:

• Check all the adjustments described in Chapter 7.

• Check that all the nuts and screws of the mechanical unit are tight.

• Check that all the electrical connections are tight.

• Check if the arm can be stopped by hand in the course of movement, both at opening and at closing. If not, check the

balance adjustment ( Chap. 7.2, page 29).

• Dust and clean the interior of the housing.

• Clean the outside of the housing and the arm by means of a soft cloth impregnated with a non-aggressive detergent.

• For the countries with a lot of sun, it is also advised to treat the outside of the body with a glossing product.

• Clean the stainless steel parts/options to prevent deposition of metallic particles (approved product reference 0/6031/000).

The frequency of maintenance must be adjusted to the conditions of use of the equipment, in particular when it

is located in an oxidizing atmosphere: near the sea, industrial environment, etc.

• Lubricate rod ends ( Fig. 28, page 32) with anti-corrosive multifunction grease.

• Lubricate the bearings ( Rep. 8, Fig. 2, page 9) and check the wear state of pivots and rings of the balancing spring.
