Responsibilities Of The Service Technician; Quality Of Parts & Fasteners - PennEngineering Haeger 824 WindowTouch4He Manuel D'utilisation

Responsibilities of the Service Technician

Field service technicians must have machine and InsertionLogic® service training. The service technician
is responsible for all repairs, upgrading and modification requested by the customer or mandated by the
Haeger Service and Support Group. The service technician who installs the machine will also provide
training for the operator that covers all of the basic skills and safety practices required to operate the
machine. Service personnel must be furnished with proper tools for the installation and maintenance of
the machine.
Quality of Parts & Fasteners
The WindowTouch-4He is designed and engineered for high volume installation of self-clinching
fasteners of all types and sizes. As a rule, the "quality" of parts and fasteners is very important to
getting the most out of your WindowTouch-4He machine. The next two paragraphs are general in
nature but critical to maximizing productivity, quality and profit potential.
Fastener Quality Basics: In general, self-clinching fasteners are designed with an annular recess in the
shank that allows the softer metal of your part (work piece) to cold form in and around it and
permanently lock the fastener in place. Inspecting the fasteners on a regular basis and verifying they are
constructed with in design tolerances is very important. With studs and stand-offs, this is especially
critical as they increase in length. We highly recommend coordination between yourself and the
fastener supplier to determine the acceptable dimensional tolerances and force requirements for your
particular application in an effort to achieve consistent quality.
Part Quality Basics: Take special care in inspecting all parts in which the fasteners will be inserted.
Verify the holes in the part meet the required specifications and tolerances. In addition, visually inspect
each part, looking for burrs and irregularities around each hole. Holes out of tolerance, burrs and
irregularities will degrade the fastener's performance and may cause difficulties during the insertion
process. We also recommend developing a consistent method of handling or holding the part (work
piece) during the insertion process to ensure quality and increase fastener performance long term.
▪ Self-clinching fasteners should be tested to be sure they meet manufacturer's
published performance data or specifications specific to the application.
