Larger machines may vibrate, bump on reversals, and degrade floor finish.
This may indicate that the base casting needs to be clamped to floor.
Larger machines need to be clamped to the floor to prevent movement between the
machine and the floor, and clamping holes are provided on all base castings for this
purpose.
The kit SHP-0116 has been developed to mount the machine to the floor without
moving it.
1. The Clamp is first mounted into the clamping hole in the base.
2. The position is marked on the floor for drilling a ½" hole into the concrete.
3. The RedHead stud is mounted in the floor with one nut and washer on it.
4. The Clamp is mounted over the stud and then the two ½ inch Socket Cap screws
are tightened, pinching the flange of the base casting.
5. The second washer and nut are tightened onto the stud, inhibiting any flexing up or
down of the base casting.
6. Recheck machine level.
Hilti (mfg in Liechtenstein) makes a Right-Angle Hammer Drill, model TE-5, with a
model TE-AC Right Angle Head attachment, that works very well in this application.
