2.2) Installation procedure for rail web electrical connection
–
Drill rail web to
13,5 mm or, if already drilled, use a suitable reamer to clean the hole (Fig. 1).
Ø
–
Check the size of the hole with the CAL135.145 "GO/NO GO" gauge (Fig. 2):
- The hole size is correct if only the green part enters the hole.
- If the red part enters, the hole is too large, in this case it is necessary to drill a new hole.

Insert the AR...-1 copper bush into the rail web hole (Fig. 3).
– Ensure that the ram in the head is fully retracted and then fi rmly screw and tighten the adaptor
M9M8 onto the tool head (Fig. 4).

plunger OG10.5C onto the adaptor M9M8 (Fig. 4) using the recess in the gauge CAL135.145.
– Operate the moveable handle of the tool (Fig. 5) to pull the plunger completely through the bush
and extrude the bush onto the surface of the hole.
At the end of the operation, press the pressure release lever (20) to retract the ram (01).
– The bush will also extrude itself around the opposite side of the rail web (Fig. 6).
