Hydraulic Feed - HF
Fig. 12. Hydraulic feed unit-HF and carriage-CE1 with the hydraulic feed unit mounted
A hydraulic feed unit is available. The feed unit is controlled by the remote control from the
Pentpak 15 or 25 or from a hydraulic/hydraulic remote control valve block.
Mounting of feed unit
1. Remove the carriage from the column.
2. Loosen the socket.
3. Assembly the hydraulic feed unit according to fig.
4. There is an allen screw inside a punched hole in the lower right corner on the power
pack. Completely tighten and then turn this screw 4 – 5 turns CCW before starting to
drill with the hydraulic feed.
5. Tighten the socket (se fig.12) on the hydraulic feed unit before hydraulic feeding is
started. Do not overtighten the socket!!!
6. For manual feed with a knuckle bar, loosen the socket on the hydraulic feed unit and
operate the LH or RH socket on the carriage.
Feeding of the drill bit
Feeding of the drill bit into the concrete is either done per hand by using a knuckle bar on the
carriage or with the help of the hydraulic feed unit. A”slow start” with reduced speed of the drill
bit can be done by just slowly pulling the lever on the hydraulic motor until the drill bit starts
rotating. By first, slowly cutting a groove, the drilling is facilitated. When using the hydraulic
feed unit the feeding speed is controlled with a potentiometer on the remote control (see
Remote control –”Potentiometer for feeding speed)
Adjust the feeding speed until an even,
continous cutting pace is reached.
