OPERATING PROCEDURE:
ELECTRIC RS-2
SECTION III
SET-UP AND OPERATION
CAUTION: Before beginning turning sequence,
know which direction to turn the valve to avoid
breaking the valve stem.
1. After plugging in power cord, push reset button
on GFI to power up unit.
2. Set speed control knob to high speed/low
torque setting (see illustration below).
3. If the valve does not move in either direction,
switch speed control to low speed/high torque
setting.
Once the valve has started turning, return the
speed control switch to the high speed/low torque
setting. This procedure will assure you that the
machine stops operating as soon as any type of
obstruction is encountered or when the valve is
seated.
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.
NOTE: If the motor overload circuit breaker
pops while attempting to free a frozen valve,
reset the circuit breaker by pressing the
reset button and attempt to free the valve
again before switching to the low speed/
high torque setting.

NOTE: More torque will be required to seat,
unseat or clear tuberculin from the valve.
