68115 / 681150 Power Drive - Counter
Adding electronic counter assembly
1. Remove set screws
2. Replace with digital counter
assembly and the two socket
head cap screws.
3. Magnet bracket should be
positioned with approximately
3/16” gap between its self and
the sensor that is fastened to
the digital counter bracket.
Make sure to watch the magnet
bracket on the first turn that it
does not “crash” into the
digital counter bracket.

Frame: Solid one-piece aluminum for strength and durability
Output Speed: Threading 2” pipe - 16rpm
Weight: 38lbs - Model 68115 45 lbs - Model 681150

Threading Pipe
Grasp the handle in the right hand and the end handgrip in the left
hand. The face of the die stock should be toward the operator.
Place the drive on the pipe as you would in handling a hand operated
die stock. Lift the handle to a vertical or nearly vertical position as in
the photo opposite.
With the palm of the left hand against the face of the die stock,
CENTER the die segments against the end of the pipe.
Continue to move the handle down to a position where the elbow is
straight and stiff and the shoulder held low so that the weight of the
operator can be placed squarely above the handle. The stance of the
operator should be at a right angle to the machine.
NOTE: When using quick-opening die stocks, apply hand pressure to
the face of the stock and switch on power simultaneously to set dies.
Wit the heel of the left hand firmly against the stock, bring the right
hand down sharply (see photo opposite) causing the segments to bite
into the pipe.
Now tighten set screws (work holders) before beginning the threading
operation.

Operating the 68115 on the Pipe
Beginning the Thread
Place the control switch in the forward or threading position. Hold oil can in left
hand. Right hand should be firm on the handle and the power switch of the tool.
Press power switch ON and cut threads applying oil as needed. Because the
68115 cuts and threads faster continuously, less oil is required.
Finishing the Thread
Approaching the end of the thread, be careful that the thread is not run onto the
pipe far enough to lock the head of the die stock. If the die stock is allowed to
lock, release the power switch immediately. Locking may not only damage die
stock, but may strip gears of the drive.
When thread is completed, shut off power. Then place the control switch in
neutral and then move to Reverse Position. Turn on power and back the dies off
to a normal starting position.
Before taking tool off of the pipe, rest control switch to Neutral or Forward
position.
Some Operating Hints
Keep Elbow straight - Weight on Handle
Wrong Right
Do not allow elbow to bend. Before turning on power, shove the handle down so
that the elbow is straight and the weight of the operator squarely above the handle.
This rule is especially true when threading larger pipe.

Some Operating Hints . . . . . .
The 68115 features a new type safety control switch. It combines the reversing switch with a
trigger type engaging switch in a manner that the operator cannot reverse the direction of rotation
without first releasing the trigger switch.
The operation of this switch is very simple, to change the direction of rotation of the machine,
simply release the trigger switch and then slide the reverse switch to either the forward or reverse
position. The machine is then ready for normal operation by depressing the trigger switch.
Care in Servicing . . . . . .
The 68115 power drive is and “on the job” tool. It is designed for everyday use and for trouble-
free operation. The frame is made of high strength cast aluminum alloy.
Lubrication . . . . . .
The bearings in the motor are of the sealed type and are lubricated. No additional lubricant is
required.
Gears . . . . . .
The gear housings on the 68115 power drive are extra large and should normally contain enough
grease for the life of the tool. However, should the tool be subjected to severe usage, provision
has been made through two grease fittings to supply additional lubricant. One of these is on the
gear case cover, just ahead of the motor, which supplies the reduction gears and the other is at the
side of the frame for lubricating the worm gear.
The grease originally supplied in the tool is a special hi-temperature grease No. 1 consistency,
readily obtainable from any of the major oil companies.
Care of the Motor . . . . . .
The motor brushes should be inspected at least once a year, according to the usage of the
machine. Always be sure to see that the brushes are returned to their original side and the
position from which they were taken. This can be done by marking the brush with a red pencil
before it is removed, to indicate the side from which it is taken.
Be sure to keep the motor clear of dust and dirt by cleaning it with an air hose from time to time.
Caution . . . . . .
Your 68115 is designed to give satisfactory service with ordinary treatment. Do not drop as this
may cause damage.

Safety Adapter
for use with 68115 Power Drive
The Safety Adapter for the 68115 Portable Power Drive is essentially a torque limiting device.
The 68115 machine has a rated capacity of 250 foot pounds of torque. Under overload
conditions, for a short interval, it may produce two (2) or more times this amount. This amount
of torque may be damaging to many devices upon which the 68115 power drive may be used.
Using the safety adapter, the operator can predetermine a safe torque limit and set the adapter to
release at this point. The machine will drive through this adapter up to this limit and then the
safety adapter will slip, thus preventing a torque overload.
The safety adapter is simply mounted. When the machine is positioned with the motor on the
bottom, the adapter is slipped into the worm gear, engaging the driving lugs on the adapter in
the slots in the ring gear, so that the spring extends to the operators left and the square drive
socket extends to the operators right. The adapter is locked in position by moving the washers
with the elongated slots over the edge of the ring gear and tightening down the screws. Loosen
handle locking screw and turn handle 180 degrees to correct operating position. Tighten screw.
The safety adapter is adjustable in that it can be set to release at any torque from 0 to 250 foot
pounds. The collar, which retains the coil spring, is threaded on its diameter. By turning this
collar and compressing the spring, the desired torque limit is set. The approximate torque
settings can be found inscribed on the shaft, to which the collar is threaded. By lining up the
outside face of the collar (the face opposite the one on which the spring bears), with a given
scribe mark, the desired torque can be selected. By turning the collar one (1) complete
revolution, the release torque can be changed by about 12.5 foot pounds. With a little practice,
the adapter can be preset to any given torque within the adapters range.
The safety adapter can be used with any of the Wheeler-Rex geared pipe threaders up to four
inch pipe maximum. However, the adapter would be more appropriate in applications where
the load might be instantly increased from a nominal load to some extreme load for exceeding
the maximum strength of the driven member. It is obvious that the safety adapter would be an
excellent safeguard when turning gate valves, opening large overhead doors, hoists, gear trains
and other applications which, because of physical limitations, might incur jamming.
The square drive socket on this attachment will handle and 15/16” or 1” male square drive.
