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.

SECTION III SET-UP AND OPERATION
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.

SECTION III SET-UP AND OPERATION
I. SET UP PROCEDURE (V alve Key & Socket):
1. Insert 1” drive adaptor into RS-2 drive hub, secure
with 1/4 20x5/8” SHCS. (Ref. 1)

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

INTRODUCTION
It is impossible to determine how much torque a valve stem can take before breaking. Size, age, condition, tuberculation, and period of time since last operation will have an effect to this. The recommended start-up procedure for operating a valve is to set the RS-2 to its lowest torque setting.

DURING OPERATION:
When operating a valve, a build up of torque can be felt by the operator. When this occurs, it is a sign of either build up of material in the valve gate slides or that the end of travel is approaching. The operator should change sides and reverse the valve direction for a few turns, doing this each time resistance is felt. This method of exercising cleans out tuberculin and other contaminant build up. The counter will keep track of how many turns you have put on the valve.
