provided solely as an accomodation 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

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.

Questions and answers
how to replace spring
To replace the spring on a Challenge JO, follow these steps:
1. Check for Issues – If the drill head won’t return or come down, inspect the lift spring for damage or jamming.
2. Remove the Old Spring – If the spring is broken or stuck, pry up the drill head and clean and oil the shaft.
3. Install the New Spring – Replace the damaged spring with a new one (such as Part Number #6385).
4. Ensure Proper Functioning – Make sure the new spring allows the drill head to return smoothly.
5. Lubricate and Test – Clean and oil the shaft, then test the drill head movement.
These steps help ensure the proper replacement of the extension spring in a Challenge JO drill.
