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.

Stop Knob (Fig. 2)

The stop knob is designed to stop the slide from moving.
To install, screw stop knob into location shown (Fig. 2).

Attaching  Feed  Handles  and  Grips  (Fig.  1)

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.

Adjusting  the  Support  Bracket  and  Spacer  for  Depth  of  Cut

(Figs. 4 & 5)

This unit is shipped from the factory set for 1" depth cutters (Fig. 4).

When  using  2"  depth  cutters,  install  support  bracket  with  spacer  on

bottom, as shown in Fig. 5.
