service is also important. An untrained operator must not attempt to service the machine as this
may cause further damage. When you have determined that a service call is required, call as soon as
possible. See the Troubleshooting and Maintenance sections for more details.

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 -4e 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 -4e 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.
