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 noncurrent,
unsupported or no longer produced by The Challenge Machinery Company, and are provided solely as
an accommodation to our customers. By providing these manuals, The Challenge Machinery Company
makes no representation or warranty as to the products, 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 these 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.

3.0 Maintenance Guide

3.1 Routine Maintenance
General
Production losses can be reduced if good maintenance practices are followed. The following
suggestions may be helpful:
1. Recognize the fact that the user of hydraulic equipment has more control over maintenance than
the manufacturer.
2. Technicians should be familiar with use, care, and limitations of the equipment. Technicians and/or
maintenance personnel SHOULD READ THIS MANUAL COMPLETELY.
3. Use properly trained maintenance personnel.
4. Establish a program of systematic preventative care for your equipment or put this machine on an
existing preventative maintenance program.
5. Analyze and isolate trouble before having any part of the equipment dismantled.
6. Be aware of how your machine should sound and perform. If the machine is not operating properly
or if it doesn’t “sound right”, stop running your job immediately and try to identify the problem.
7. Call the dealer for any problems that cannot be handled by your own personnel.
Always handle drills with care to avoid severe lacerations, even dull drills
are sharp enough to cause lacerations.
Daily
1. Keep drills sharp! Sharpen drills often and reset the drill depth if needed.
2. Lubricate the hollow drills frequently with the Drill-Ease provided.
3. For better hollow drill life, remove the drills when not in use and soak in light oil. Wipe off excess
oil before drilling.
4. Wipe off excess grease from the drill heads and idlers.
Weekly (or every 40 hours of operations)
1. Spray the chip chute with silicone spray to prevent the drill chips from sticking and piling up.
Monthly
1. Oil the table height adjusting knob shaft with a light machine oil. Wipe off excess oil.
2. Check the hydraulic oil supply for the proper level. This check is made by removing the rear panel
and visually checking the hydraulic oil level in relation to the oil fill line located on the hydraulic tank
(fig. 2 page 8). The oil level should be no higher then the oil fill line to allow room for expansion of

8
the oil when running. Use only a recommended premium grade anti-wear hydraulic oil series ISO
VG 100. Oils other then the recommended type will cause seals, cups and ‘o’-rings to deteriorate.
Fig. 2
Yearly
1. Check all adjustments
2. Tighten all screws
3. Change the hydraulic oil in the reservoir. Oil may have to be changed more often if
contamination of any kind gets in the oil.
Vertical Table Guide
PINCH POINT: This adjustment requires a guard to be removed for
adjustment and testing purposes only. Be very careful while adjusting. Replace all guards before
operating. DO NOT operate machine with any guards removed.
The vertical guide block is located on the right side of the machine beneath the table and may need
periodic adjustments to keep the table steady, yet allow it and stock to fall away from the drills as rapidly
as possible. The table down stroke is controlled by the weight of the table (gravity) and return springs.
Remove the guide block cover guard. Tighten the two guide block lock nuts (fig. 3) and power the table
up by pressing the foot pedal. Gradually back the lock nuts off evenly until the table releases freely.
Retest the upstroke and table return, and check the table for side play. Replace guard.

Fig. 3
PINCH POINT: Replace guard after adjusting
Hydraulic
Through normal use, hydraulic systems gum up and seals wear. Signs of wear are hydraulic leaks and
erratic operations of the vertical speed. Check with your Authorized Dealer for a current repair and/or
replacement policy.
NEVER USE Automatic Transmition oil or brake fluid as a substitute! Oils
other than the recommended type (premium grade anti-wear hydraulic oil ISO series VG 100) will cause
seals, cups and O-rings to deteriorate. Unsafe operating conditions will result.
Drill Heads
Through normal use, bearings will wear and need replacement. Signs of wear are excessive noise,
heat or loose spindles.

4.0 Troubleshooting
Never work on this machine with the power on unless the instructions
say the machine power must be on. Lock the power off at the wall disconnect switch. See 2.2
Power Lockout Procedure page, 4.
Whenever repairing hydraulic components, loosen connections slowly
to bleed off any trapped pressure.
