The Challenge Machinery Company provides owner's
manuals on its products solely as a courtesy to its customers.
See the information below before using this manual.
These manuals are for reference only. These manuals include products which are non-
current, unsupported or no longer produced by The Challenge Machinery Company, and are
provided solely as an accomodation to our customers. By providing these manuals, The

their current condition, or their suitability or fitness for use in any particular application, which
are the sole and independent responsibility of the product owner and user.
Older products may not comply with current safety procedures, guidelines or regulations,
and it is the product owner's and user's responsibility to evaluate the suitability and fitness of
the products in their current use and application. The Challenge Machinery Company makes
no representation, warranty or recommendation regarding any modifications which may be
required on non-current or unsupported products. The Challenge Machinery Company
assumes no liability for any modification or alteration to any Challenge product, and any such
modification or alteration to any Challenge product is not authorized by The Challenge
Machinery Company. The availability of these manuals is solely for the purpose of providing
reference information for the products.
This manual may not be complete in all aspects of product maintenance and repair. All
products should be used only by qualified and properly trained personnel, following proper
safety procedures. All products should be regularly inspected and maintained, and their condition,
application and use should be periodically evaluated by qualified personnel. Only qualified and
properly trained technicians should perform maintenance, repair and replacement
procedures. Attempting t hese procedures without proper training may cause machine
damage or operator injury!
Products may be unsupported by The Challenge Machinery Company due to age or the
unavailability
of parts from their original manufacturer. No parts or product support will be
available to repair or maintain unsupported products. Older products may not be UL listed (if
the product does not have a UL label it is not a listed product), and may not comply with
applicable installation or other regulations or requirements if
relocated to a new facility.
Many municipalities require a product to be UL listed before an electrician will connect power
to them. Often the cost of updating an older product to comply with current safety regulations is
greater than the value of the product.

and washers in the tool kit. Place the washers under the bolt heads and insert bolts through
the table into the drill base, finger tighten only.

3. Lift the drill so it is now standing upright, resting on the table support. Insert the two 5/16-
18x3/8 socket set screws found in the tool kit into the ends of the cross shaft. Place the two
ends of the handle into the holes in the cross shaft. With the bottom edges of the handle flush
with the bottom of the shaft, tighten the setscrews.
4. Next, install the backgauge. While holding the thumbscrew of the backgauge to the right side,
slide the backgauge onto the table. Lift the pressure foot up and slide the backgauge
underneath. Position the backgauge at the 1" marks on the table scales. Tighten the
thumbscrew.
