9 Maintenance and repair Adjusting proximity switch (METRO H** only) METRO 0.5 to 1.5 Note Make sure that no parts fall into the unit. Cover the opening of the machine and bin. Unscrew the M6 hexagon-headed screw [7]. Using a forked wrench (WAF 9), push against the contact surface of the piston rod [4]. Press the spacer rod [3] back manually and pull the sealing disk [5] out. Remove the spring [8]. Slacken the hexagon nut [1] on the pneumatic cylinder [11]. Unscrew the pneumatic cylinder [11] and remove the implosion valve [2]. Loosen the spacer rod with forked wrench (WAF 9). Using a forked wrench (WAF 9), push against the contact surface of the piston rod [10]. Unscrew the spacer rod [3]. Installation Assemble in reverse order. Make sure that the sealing disk [5] contacts the seal [6] after assembly. Lock the thread of the piston rod [9] with Loctite 270 and the hexagon-headed screw [7] with Loctite 242. 9.6 Adjusting proximity switch (METRO H** only) 2 1 Fig. 9.7 – Adjusting proximity switch [1] Proximity switch [2] Hexagon nuts Prepare the hopper loader for maintenance (see "Before starting work" on Page 32).

Installation position: see diagram 9.8. Tighten the set screw and lock it with Loctite 242. Fig. 9.9 – Adjusting discharge flap [1] Spring-loaded thrust pad [2] Discharge flap [3] Discharge Screw the spring-loaded thrust pad [1] (see figure 9.9) up until the gap between the discharge [3] and the discharge flap [2] is 5-8 mm. Note The air gap at the discharge flap ensures that particles of granulate on the discharge flap are sucked in by the vacuum at the start of transport. The discharge flap is pulled up by the vacuum and forms an airtight seal. Edition: November 2005 39
