8. Connect the hydraulic lines to the hydraulic power unit. See the Hydraulic power
section on page 43 for preparation and how to connect the lines.
CAUTION
To avoid damage to the hydraulic power unit pump, connect the
motor to the power unit before plugging in and turning it on.
3.7 Mounting the Mechanical Axial Feed Unit
The axial feed unit can be mounted to either end of the boring bar. The hexagon hole
in the output shaft fits onto the hexagon end of the bar lead screw.
1. Place the axial feed unit in NEUTRAL so the lead screw drive can rotate in either
direction. See Section 3.7.1 on page 27.
2. While holding the axial feed unit against the bar end cap, turn the output shaft
until the hexagons fit together.
3. Tighten the mounting cap screws.
4. Secure the stop rod to a stationary object to engage the feed mechanism.
TIP:
If the axial feed unit is moved to the opposite end of the bar, the
feed direction will be reversed. Check the feed direction before
operating the machine.
