PNEUMATIC MODEL:
OPERATING PROCEDURE:
Pneumatic Pow-R-Drive II
1. Rotate torque control knob counterclock
wise to the lowest torque setting (Figure 4).
2. press the power on lever in either forward or
reverse direction. If valve does not turn,
release lever and rotate motor direction ring
on motor body and repeat procedure.
3. Continue this process, increasing the torque
value 1/4 turn on the torque control until valve
stem breaks free. This method ensures that
only enough torque is supplied to turn the
valve. Once the valve has started turning,
reduce the torque setting to the lowest setting
which will keep the machine operating. This

SET-UP AND OPERATION
FIGURE 4
NOTE: When lever is depressed, torque indi-
cator will read the torque value being applied
to valve stem.
CAUTION: Before beginning turning sequence,
know which direction to turn the valve to avoid
breaking the valve stem.
CAUTION: PRD II Must be used with an inline
filtration system to stop water and air borne
contaminents. FAILURE TO COMPLY WILL DAM-
AGE MOTOR AND VOID WARRANTY.
NOTE:
1. More torque will be required to seat, un-
seat or clear tuberculin from the valve.
2. Maximum torque cut-off can be reset by
free running Pow-R-Drive II with no load and
adjusting torque control until torque indica-
tor gauge reads desired torque cut-off.
procedure assures you that the machine will
stop operation as soon as any type of obstruc-
tion is encountered or valve begins to seat.
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.
USE OF AIR LINE OIL:
An in-line oiling system should be utilized when
operating the pneumatic Pow-R-Drive II to lu-
bricate 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 Anti-
