2. INSTRUCTIONS FOR USE (Ref. to Figs. 1 ÷ 7)
2.1) Setting
The head is equipped with a "self-lock"quick male coupler suitable for connection to a hydraulic,
pneumatic or electrical pump from the CEMBRE range.
2.2) Drill rail web or, if already drilled, use a suitable reamer to clean the hole (Fig. 1).
2.3) Check the size of the hole with the "GO/NO GO" gauge CAL ....; the hole size is correct only if
the green part enters the hole. If the red part enters, the hole is too large (Fig. 2).
2.4) Insert the AR...-1 copper bush into the rail hole (Fig. 3).
2.5) Insert the calibrated plunger OG ... into the bush, on the flange side (Fig. 4).
Ensure that the ram, in the head is fully retracted. Using the recess in the gauge CAL .... screw
and tighten the plunger OG... into the tool head (Fig. 5).
2.6) Operate the pump, to pull the plunger OG ... through the bush and extrude the bush onto the
sides of the hole (Fig. 6).
2.7) The bush will also extrude itself around the opposite side of the rail web (Fig. 7).
3. CONDUCTOR ASSEMBLY (Ref. to Figs. 8 and 9)
3.1) Insert the special bolt (with recessed head) through the copper bush. The screw thread should
protrude from the flange side of the bush; the recessed bolt head will tighten onto the web of
the rail and not onto the bush (Fig. 8).
3.2) Crimp the lug onto the conductor. Assemble the lug to the flange of the bush over the pro-
truding bolt.
3.3) Fit the flat washer and the self-locking nut. (Fig. 9).
