SECTION IISAFETY INSTRUCTIONS
Read the Following thoroughly before proceeding
Since 1883, EH Wachs has built a reputation for
quality and a commitment to consumer satisfaction.
In accordance with this, Wachs must take on the
added responsibility of doing our best to assure the
safest use of our equipment.
We have assembled a list of safety reminders to
aid in creating the safest possible working environment. We recommend that the precautionary steps
listed there be closely observed.
1. READ THE OPERATING MANUAL!!
Reading the setup and operating instructions prior to
beginning the setup procedures can save valuable time
and help prevent injury to operators or damage to ma-
chines.
2. INSPECT MACHINE & ACCESSORIES!
Prior to machine setup physically inspect the machine
and it's accessories. Look for worn tool slides, loose bolts
or nuts, lubricant leakage, excessive rust, etc. A properly
maintained machine can greatly decrease the chances
for injury.
3. ALWAYS READ PLACARDS & LABELS!
All placards, labels and stickers must be clearly legible
and in good condition. Replacement labels can be pur-
chased from the manufacturer.
ALWAYS WEAR PROTECTIVE EQUIPMENT:
WARNING
Impact resistant eye protection
must be worn while operating or
working near this tool.
For additonal information on eye and face protection, refer to
federal OSHA regulations, 29 Code of Federal Regulations,
Section 1019.133., Eye and Face Protection and American
National Standards Institute, ANSI Z87.1, Occupational and
Educational Eye and Face Protection. Z87.1 is available
from the American National Standards Institute, Inc., 1430
Broadway, New York, NY 10018
CAUTION
Personal hearing protection is required at all times when operating or working near this tool.
Hearing protectors are required in high noise areas, 85dBA
or greater. The operation of other tools and equipment in the
area, reflective surfaces, process noises and resonant
structures can substantionally contribute to and increase
the noise level in the area. For additional information on
hearing protection, refer to federal OSHA regulations , 29
Code of Federal Regulations, section 1910.95, Occupational Noise Exposure and ANSI S12.6 Hearing Protectors.
4. KEEP CLEAR OF ROTATING PARTS!
Keep hands, arms and fingers clear of all rotating or
moving parts. Always turn machine off before attempting
any adjustments requiring contact with the machine or it's
accessories.
5. SECURE LOOSE CLOTHING & JEWELRY!
Loose fitting clothing, jewelry; long, unbound hair can get
caught in the rotating parts on machines. By keeping
these things secure or removing them you can greatly
reduce the chance for injury.
6. KEEP WORK AREA CLEAR!
Be sure to keep the work area free of clutter and nonessential materials. Only allow those personnel directly
associated with the work being performed to have access
to the area if possible.
CAUTION
Some individuals are suseptible to
disorders of the hands and arms
when exposed to tasks which involve repetitive motions and/or vibration. Disorders such as Carpal
Tunnel Syndrome and Tendonitis
can be caused or aggravated by
repetitious, forceful exertions of the
hands and arms.
!Use minimum hand grip force.
!Keep wrists straight
!Avoid prolonged, continuous vibration exposure
!Avoid repeated bending of wrists and hands.
!Keep arms and hands warm and dry.

necessary to start with a nut and stem
jammed against the bonnet, and there will be
no guesswork about which way to turn
the nut because the valve will be free. Also, if
it is inadvertently turned the wrong way , one
or two turns can be made before a positive
stops occurs, and by reversing direction, full
operation of the valve can be effected.
Using the RS-2 machines to operate valves
is easier on the valve because a steady
turning torque is applied rather than jerky
motions. This prevents the stem breakage
that is sometimes caused by turning the
valve by hand. Also, more valves can be
Valve Maintenance Procedure
A valve that has not been operated for a number of
years needs to be closed by using a series of up
and down motions. Occasionally , crews attempting
to close a difficult valve use a T -handle or a cheater
bar, applying a great deal of pressure in one direction simply to force the valve closed. The correct
way to exercise a valve is to begin with a steady
amount of torque in the direction necessary to close
the valve, moving through five to ten rotations, then
the direction should be reversed for two or three
revolutions, followed by five or ten more turns in the
closing direction. This procedure should be repeated until full closure is attained.
The reason for the cautious approach is that
tuberculation and sediment have probably built up
on the gates, stem, and slides. By using the procedure described, water in the system can flush the
debris that has broken away from the gate slide.
The stem is exercised through the series of
up and down motions. Once the valve has been fully
closed, it should be opened a few turns so that the
higher velocity water flowing under the gates can
move the remainder of the sediment downstream.
After the valve is reopened, it should be turned in
the closing direction one or two revolutions. Thus,
the next time the valve is operated, it will not be
turned in less time. A further advantage is that
information about each valve can be generated automatically by the revolution counter
and torque gauges for inclusion on permanent records.
HOW TO DETERMINE AN
UNKNOWN VALVE ROTATION:
When the direction to turn the valve
stem is not known, select a rotation
direction and proceed with caution. If
resistance is felt, immediately reverse
the rotation. Continue this procedure,
reversing direction when resistance is
felt, until a free turning direction is
achieved. Document the direction,
open or closed position, and number
of turns required.

II. OPERA TOR POSITIONING
Standing on the wrong side of the machine will allow
the handle to PUSH against the operator and can
knock him off balance or pin him against an obstacle if
torque suddenly increases. When positioned properly,
an increase in torque will PULL the handle and control
out of the operator’s hand and stop the machine (See
illustrations below).
IMPORTANT: Always refer to the manual or the valve
direction decal located on valve handle for correct
operation positions.
Ref. 2
3. Install stop collar at a comfortable operating height
to support the weight of the RS-2.
4. Mount the RS-2 on the valve key and rest on stop
collar. Connect the power source.
5. Zero the counter when valve is ready to be turned
by pressing the red reset button on the counter face.
Always use the counter to determine the number of
rotations the valve has turned.
6. Determine direction of valve rotation and which
side of RS-2 to operate from. The operator should
stand on the side of the machine which allows the
torque to PULL the machine handle away from his
body .
CAUTION: The RS-2 is capable of producing up
to 800 ft./lbs. of torque to turn valves. It is very

USE OF AIR LINE OIL:
An in-line oiling system should be utilized when
operating the pneumatic Pow-R-Drive II to lubricate
motor on a continuous basis.
When continuous load and high torque settings
are required, the use of an antifreeze oil to
lubricate the motor will reduce ice buildup and
maintain motor performance. (Kilfrost AntiFreeze Solution, Wachs Part No. 02-403-00)

of the handle assembly near the powerhead.
A convenient quick release pin attached to the

An extension handle should be used when the
