5 Ton Ram Instruction Manual Externally Swaged Holedall 1 Before you begin, make sure the ram is fully retracted. Install 25PUSH400 (also referred to as the pusher hat) onto the main pusher plate. This is required for all standard Holedall fittings. Make sure the bolt holes align with the 1/2” bolts and wing nuts supplied. 2 Insert Die Holders into the Die Bed Plate as follows: a) DH9-004 - Master Die Holder to hold all of the other die holders. b) DH9-004-1 - Die Holder for 4” I.D. hoses only.

If the hose is to be static grounded, follow hose manufacturers procedure for proper static grounding. 6 Lubricate the I.D. of the hose and the O.D. of the stem with Dixon lubricant or equivalent.

After installing the die halves, push the hose up into the pusher until the ferrule comes in contact with the pusher.
