General Information

Introduction

Thank you for purchasing the PACE model ST 75 Soldering/Desoldering System.
This manual will provide you with the information necessary to properly set up,
operate and maintain the ST 75 system.

The ST 75 systems are available in either the 115 VAC, or 230 VAC version which
incorporates a highly responsive SensaTemp (closed loop) control system providing
up to 80 Watts of total power to a single output channel. The 230 VAC version
system bears the CE Conformity Marking which assures the user that it conforms
to all the requirements of council directive EMC 89/336/EEC. The systems
package the power source with a selection of accessories and functional aids.

The PACE Sodr-X-Tractor handpiece provides thermally enhanced thru-hole
desoldering, safe removal of TQFP (Thin Quad FlatPack) and TSOP (Thin Small
Outline Package) surface mount components and continuous removal of old solder
from surface mount lands.

PACE SensaTemp handpieces may be used with the ST 75 system to perform a wide
variety of advanced surface mount & thru-hole component removal/replacement
operations.

Safety

Safety Guidelines - English Language

The following are safety precautions which personnel must understand and follow
when using or servicing PACE products.

1. POTENTIAL SHOCK HAZARD - Repair procedures on PACE products

should be performed by Qualified Service Personnel only. Line voltage
parts may be exposed when the equipment is disassembled. Service
personnel must avoid contact with these parts when troubleshooting the
product.

2. To prevent personnel injury, adhere to safety guidelines in accordance
with OSHA and other applicable safety standards.

3. SensaTemp handpiece heaters and installed tips are hot when the
handpiece is powered on. DO NOT touch either the heater or the tip.
Severe burns may result.

4. PACE Tip & Tool Stands and handpiece cubbies are designed specifically
for use with the associated handpiece and houses it in a manner which
protects the user from accidental burns. Always store the handpiece in its
holder. Be sure to place the handpiece in its holder after use and allow to
cool before storing.

5. Always use PACE systems in a well ventilated area. A fume extraction
system such as those available from PACE are highly recommended to
help protect personnel from solder flux fumes.

6. Exercise proper precautions when using chemicals (e.g., solder paste).
Refer to the Material Safety Data Sheet (MSDS) supplied with each
chemical and adhere to all safety precautions recommended by the
manufacturer.

Sécurité

Directives de Sécurité, Française Langue

Les précautions suivantes, sont celles que le personnel doit comprendre et suivre
lorsqu'il utilise, effectue la maintenance ou se sert d'un produit PACE.

1. Danger potentiel de choc èlectrique - Les procédures de réparation sur

les produits PACE doivent être effectuées seulement par du personnel
qualifié. Des parties de l'équipement désassemblées peuvent être sous
tension. Le personnel de maintenance doit éviter tout contact avec ces
parties en réparant le produit.

2. Pour prévenir tout préjudice, le personnel adhère au guide de sécurité en
accord avec OSHA (équivalent à des normes françaises de sécurité) et
d'autres standards de sécurité applicable.

3. La mise sous tension des outils SensaTemp comporte des éléments
chauffants (buse). Ces derniers, gardent la chaleur même après la mise
hors tension pendant un certain temps. Ne pas toucher les parties
chaudes aux extrémités des outils. Des brûlures sévères peuvent en
résulter.

4. Les outils PACE et leurs pannes ainsi que le support sont dessinés de
manière spécifique afin de protéger l'utilisateur/opérateur de brûlures
accidentelles. Reposer toujours les outils après chaque utilisation dans
leurs étuis/supports afin de permettre leur refroidissement.

5. Utiliser toujours les stations Pace dans unlieu bien ventilé. Des
extracteurs de fumée Pace sont hautement recommandés pour protéger
votre personnel des vapeurs de soudure/flux.

6. Prenez les mesures nécessaires quand vous utilisez des produits (ex:
solder paste) chimiques. Reportez-vous au document (fiche technique/
sécurité) du fabricant fourni avec chaque produit. Respectez toutes les
procédures de sécurité recommandées par le constructeur.

Sicherheit

Sicherheit Korrekturlinien, Deutsche Sprache

Die nachfolgenden Sicherheitsvorschriften sollten vom Bedien- un Servicepersonal
verstanden und befolgt werden.

1. Entladung spannungsfuehrender Teile - Reparaturen an PACE Produkten

sollten nur von qualifizierten Personal durchgefuehrt werden.
Spannungsfuehrende Teile koennen sich bei gezogenen Netzstecker
entladen. Servicepersonal muss den Kontakt dieser Teile vermeiden.

2. Um moegliche Gefahren fuer Personen auszuschliessen, muessen alle

Sicherheitsvorschriften in Uebereinstimmung mit OSHA und anderen
anwendbaren Sicherheitsstandards eingehalten werden.

3. Angeschlossene SensaTemp Heizelemente von Handwerkzeugen und

installierte Loetspitzen sind heiss wenn das System eingeschaltet ist oder
erst vor kurzer Zeit ausgeschaltet wurde. Heizelement und Loetspitze
nicht beruehren. Verbrennungsgefahr.

4. PACE Tip & Tool und andere Handwerkzeugablagen sind so konstruiert,

dass ein versehentliches Beruehren des dazugehoerendes
Handwerkzeuges vermieden wird. Bewahren Sie das Handwerkzeug nach
Gebrauch stets in der Ablage auf. Bevor das Handwerkzeug an einem
anderen Ort gelagert werden muss, lassen Sie es in der Werkzeugablage
vollstaendig abkuehlen.

5. Benutze PACE Systeme nur in gut beluefteten Raeumen. Ein

Loetrauchabsaugsystem, wie es z.B. von PACE erhaeltlich ist, hilft
Bedienpersonen von den Gefahren von Loetrauch zu schuetzen.

6. Wenn Chemikalien (z.B.: Lotpaste) verwendet werden, muessen alle die in

den Sicherheitsdatenblaettern des Herstellers ausgewiesenen
Sicherheitsvorschriften eingehalten werden.
