TOOL ASSEMBLY

To reduce the risk of injury, always unplug tool before

attaching or removing accessories or making adjustments.

Use only specifically recommended accessories. Others

may be hazardous.

WARNING!

1. Assemble the feed handles and grips to the hub. Tighten securely.

2. To mount the hub to either side, align the two (2) dowel pins on the

hub with the holes in the pinion. Tighten the handle screw.

Adjusting the Gib Assembly (Fig. 3)

Fig. 1

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

adjusting 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.
