Safety
General
The general agreement concerning safety regulations in the VDE 0701 standard applies analogously.
The operation of Weld trimmers is subject to the applicable national regulations.
Apart from the instruction book and the obligatory regulations for accident prevention applicable in the
country of use and application location, the technical regulations for safe and professional operation
must be observed. Guideline 92/57/EWG of 24.06.1992 applies analogously.
Not only the general safety instructions listed in this chapter but also the special safety instructions
added to the other main points must be observed.
Do not attempt any operation which may be a safety hazard.
Intended use
The Weld trimmer has been constructed according to the latest technology and safety regulations.
However, improper use may lead to hazards for the user or a third party or damage to the machine and
other material assets.
The Weld trimmer must only be used if it is in excellent technical condition. Use the Weld trimmer
according to regulations and be aware of safety and hazards described in the instruction handbook.
If the Weld trimmer fails to function correctly, stop work immediately and secure! Mal-functions
should be eliminated (or have them eliminated) straightaway.
The Weld trimmer is only to be used as agreed in the order confirmation. Another use or use beyond
this is not as intended. The manufacturer/supplier is not liable for damages resulting from this. The
user is solely responsible. Intended use involves observance of the instruction hand-book and keeping
to the inspection and maintenance conditions.
If a new application of the Weld trimmer lies outside the limits of use defined in the order
confirmation or if the user is in doubt regarding changes, the change must be approved by the
manufacturer/supplier.
Organizational measures
Always keep the instruction handbook ready to hand at the location where the Weld trimmer is in use.
Observe the general, legal, national and other compulsory regulations on accident prevention and
environmental protection in addition to those described in the instruction handbook.
The individual appointed to undertake work using the device must have read the instruction hand-book
before start working, paying particular attention to the chapter on safety instructions.
If changes are made to the Weld trimmer or its operating performance relevant to safety, stop working
with the Weld trimmer immediately and report the malfunctions to the authority/person responsible.

If safety devices have to be removed during set-up, maintenance and repair, these must be reassembled
and inspected once the maintenance and repair work has been concluded.
According to VDE 0701 (IEC 335), it is stipulated, that the protective resistor, insulation resistance
and the current earth leakage must be measured after every maintenance or change. In addition a visual
inspection of the connecting cable, a voltage and electric charge measurement and a functional check
must be carried out.
Make sure process materials as well as replacements parts are disposed of safely and with con-
sideration to the environment.

Product description
General
The Weld trimmer is equipped with a speed-controlled, motor. The on/off switch is a slide switch with
a fast unlocking device operated by pressure on the back end of the slide switch.
The Welding trimmer consists of a strong motor and a cutter head, which is flanged on the angular
gear. The cutter head has a safety cover, which opens only during operation to release the cutter
knives.
The safety cover is opened by two rubber feet, which is mounted on the cutter head. It will open when
the Weld trimmer is placed on the work piece and is moved in working direction.
The Weld trimmer consists of a fixed housing with two slide discs. Inside the housing the cutter head
rotates with four knives. The cutter head rotates against working direction.
A constant attack on the working piece is warranted by the arrangement of the knives.
If the performance of the Weld trimmer is definitely decreasing, the cutter knives have to be replaced.
The cutter knives have two cutting edges and can be turned once.
See chapter maintenance.
The plating of the machine on the working place by the glide discs enables working without any difficulties,
also on curved surfaces.
Inspection
All MUNSCH Weld trimmers are subject to extensive performance inspection before delivery. Only
aggregates in perfect technical condition leave the factory.
By observing this instruction handbook and the agreed operating conditions trouble-free operation is
guaranteed.
