WARRANTY
Ruska Instrument Corporation warrants its products to conform to or exceed the
specifications as set forth in its catalogs in use at the time of sale and reserves the right,
at its own discretion, without notice and without making similar changes in articles
previously manufactured, to make changes in materials, designs, finish, or specifications.
Ruska Instrument Corporation warrants products of its own factory against defects of
material or workmanship for a period of one year from date of shipment.
Liability of Ruska Instrument Corporation under this warranty shall be limited to
replacing, free of charge (FOB Houston, Texas), any such parts proving defective within
the period of this warranty, but will not be responsible for transportation charges or
consequential damages.
This warranty is not made for products manufactured by others which are illustrated and
described in Ruska catalogs or incorporated in Ruska products in essentially the same
form as supplied by the original manufacturer. However, Ruska Instrument Corporation
agrees to use its best efforts to have original suppliers make good their warranties.

SAFETY SUMMARY
The following are general safety precautions that are not related to any specific procedures and
do not appear elsewhere in this publication. These are recommended precautions that personnel
must understand and apply during equipment operation and maintenance to ensure safety and
health and protection of property.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must at all times observe safety regulations. Do not replace components or
make adjustments inside the equipment with the voltage supply connected. Under certain
conditions, dangerous potentials may exist when the power control is in the off position due to
charges retained by capacitors. To avoid injuries, always remove power from, discharge, and
ground a circuit before touching it.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt internal service or adjustment unless another person capable of rendering aid
and resuscitation is present.
RESUSCITATION
Personnel working with or near dangerous voltages shall be familiar with modern methods of
resuscitation. Such information may be obtained from your local American Medical Association.
ELECTROSTATIC DISCHARGE SENSITIVE PARTS
CAUTION: Electrostatic discharge sensitive (ESDS) is applied to low power, solid-state
parts which could be damaged or destroyed when exposed to discharges of static
electricity. Maintenance personnel are often not aware that an ESDS part has been
damaged or destroyed because electrostatic discharges at levels less than 4,000 volts
cannot be seen, felt, or heard.
When the ESDS symbol appears between a paragraph number and paragraph title, the
entire paragraph and all subparagraphs shall be considered ESD sensitive. When the ESDS
symbol appears between a step number and the step test, the step shall be considered ESD
sensitive.
COMPRESSED GAS
Use of compressed gas can create an environment of propelled foreign matter. Pressure system
safety precautions apply to all ranges of pressure. Care must be taken during testing to ensure
that all pneumatic connections are properly and tightly made prior to applying pressure.
Personnel must wear eye protection to prevent injury.
PERSONAL PROTECTIVE EQUIPMENT
Wear eye protection approved for the materials and tools being used.
INERT GASES
Operation of pressure equipment may be accompanied by the discharge of inert gases to the
atmosphere. The result is a reduction of oxygen concentration. Therefore, it is strongly suggested
that exhaust gases not be trapped in the work area.
