Figure 3: Impact device components
Figure 3 is a representation of the most important parts that make up
an impact device and the procedure used to remove the impact device
tip. Over time and depending on the number of measurements that
you make, the impact tip located on the impact device body must be
replaced. In order to do this turn the support ring clockwise (see figure
3-1) until the ring is released and the impact body falls off (figure 3-2).
Make sure you catch the impact body or that you work over a soft
surface where the impact body can fall on without being damaged.
Remove and replace the impact tip making sure everything is perfectly
clean and repeat this procedure to re-assemble the impact device.
