Attaching accessories

5.8.1 Connection systems for accessories
By default the ram jack has ram heads on both sides. These ram heads can be removed and replaced
by accessories.
To connect these accessories a cam and steel ball connection system is used. The pulling shoes,
however, have a different connection system. They can only be attached and locked with a ring.

The steel ball (C) in the groove (E) and the cam (A) serve to hold the accessory in place.
To attach
• Position the cam (A) of the accessory (F) in front of the recess (D).
• Push the accessory firmly on to the ram jack (B) until the steel ball (C) clicks in the groove (E).
• Turn the accessory 180° with respect to the ram jack so that the recess provides extra locking.

time. When the cam comes to the recess (D) the accessory is released.
