TOOL ASSEMBLY

WARNING! Adjusting the Gib Assembly (Fig. 3)
Fig. 3
To adjust the gib, loosen or tighten the gib adjustment set screws on the
side of the support housing accordingly with the 3/32" hex key provided.
Tightening the set screws increases friction on the slide. The gib should be
set tight enough to support the weight of the drill in any position. All adjust-
ing screws should be set to provide smooth and even travel over the entire
length of slide movement.
The set screws contain a nylon patch that prevents them from moving
freely. Additional adjustment of the gib may be required from time to time
with extended use of the tool.
