Challenge EH-3D Technical Service And Parts Manual

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.
