24 Safety and Servicing Information
Note
If you find you need excessive downwards pressure to keep the
screwdriver tip in the Pozidriv screw head, you are probably using
the wrong type or size screwdriver.
Figure 1.3 below shows the main differences between typical Pozidriv and
Phillips screw heads and screwdriver tips (actual hardware may differ slightly
from these illustrations due to variations in manufacturing techniques).
