3.10. Adjusting the gib clearance
Every 50 operation hours, or more often, check the gib clearance because it greatly
influences the quality of drilled holes. The clearance is appropriate if the motor slides
smoothly and not drops under its own weight.
To remove the excessive clearance, use the 8 mm combination wrench to loosen
the nuts (
1
, Fig. 11), and then use the 2.5 mm hex wrench to loosen the set screws (
2
).
Next, rotate the spoke handles to set the motor on such a level to access the gib
screws through the holes, use the 4 mm hex wrench to loosen these screws (
3
), and
then tighten (
4
) with a force enough to prevent the gib from being pushed out by the
springs located inside.
Use the 2.5 hex wrench to tighten the set screws (
5
) to such an extent that the
motor moves smoothly through the entire stroke and not drops under its own weight.
Next, use the 4 mm hex wrench to tighten the gib screws: central screw (
6
), adjacent
screws, and then top and bottom screws. Finally, use the 8 mm combination wrench to
tighten the nuts (
7
), while countering the set screws using the 2.5 mm hex wrench (
8
).
