4 - LEFT OR RIGHT HAND INSTALLATION OF THE PISTON AND SPRING
360°
ROTATE THE PISTON
ON ITSELF TO
RELEASE IT FROM
PIPES AND CHANGE
ITS POSITION
SPRINT barrier is supplied with left-hand opening arm as standard; it is possible to change the opening
direction by moving both the piston and the balancing spring.
4.1. Before carrying out the moving operation, release the operator - see chapter 13 - and, on the hydraulic
unit, LOOSEN THE TWO FITTINGS OF THE HYDRAULIC PIPES BY HALF A TURN (pipes connecting hydraulic unit to
the piston) to simplify the piston rotation.
Be careful not to choke the hydraulic pipes! (not visible in the figures!)
4.2. CHANGE OF THE OPENING DIRECTION - (RIGHT-HAND OPENING)
- unscrew and pull out the balancing spring - Fig. 11
- unscrew the hydraulic piston - Fig. 8, move it gently from its position by rotating on itself 360° - Fig. 9 - to
release it from the hydraulic pipes and prevent them from intertwining, then place the piston on the opposite
side of the barrier and tighten with the fixing screws - Fig. 10
- lubricate the piston rod-end spherical bearing with DIN 51502 KP 2 N-20 - K 2 K-20 grease
- place the balancing spring on the opposite side of the barrier, greasing the parts indicated in Fig. 12
4.3. In case of ordinary replacement of the spring, according to the barrier opening direction, disassemble
the old spring and reassemble the new one following the tightening instructions in Fig. 11 or in Fig. 12
