Safety
1. Know your Power Drive. Read the Operator's Manual carefully. Learn the
operation, application, and limitations as well as the specific potential hazards
peculiar to this tool.
2. Use right tool. We recommend use of 775 Support Arm. The Support Arm
assures safer operation when using the 700 Power Drive horizontally,
vertically or overhead because once it is secured to the pipe to take up the
threading torque, both hands are free to mount the Power Drive into position.
When the job is completed, the Power Drive and Support Arm can be
removed separately assuring safer job take down. Do not force small tool or
attachment to do the job of a heavy-duty tool.
3. Secure work. Use clamp, bench vise or stand vise to hold pipe which is not
otherwise rigidly supported or attached.
Operation
Threading with drop head die heads.
1. 1/8" - 2" RIDGID 12-R Die Heads fit into the RIDGID 700 power threader without
the need for adaptors. Simply push Die Heads spline end first, squarely into
Face Gear until spring catches securely. (See fig. 1).
Check that pawl is fully engaged by rotating diehead by hand.
For right hands threads, installation is as shown in fig. 2a.
For left hand threads, installation is as shown in fig 2b.
Note: The direction change switch is used to back-off the Die Head when the
thread is completed. See fig. 2c.
Important: When threading pipe, the No. 775 Support Arm should be used
and securely locked on the pipe as shown in Figures 3 and 4. To use the
Support Arm and Power Drive together correctly refer to
Figures 3 and 4. Failure to follow these instructions could result in injury to
operator because of torque developed during threading.
2. Place Die Head (already installed in Power Drive) over end of pipe. When using
make sure Power Drive is correctly positioned on Support Arm. For Right Hand
threads, Die Head should rotate CW. (looking at face of Die Head).
Note: During threading, apply plenty of RIDGID Thread Cutting Oil to dies.
3. Simultaneously actuate switch button and exert pressure on machine to make
sure thread is started. Keep switch button depressed until threading is
completed. Releasing switch button will stop the Power Drive.
Caution: Hold onto Power Drive handle firmly to resist initial torque while
backing off Die Head.
4. To back off Die head from threaded pipe, set direction switch to back off
position. See fig. 2d. Actuate paddle switch. When dies clear end of pipe, grip
handle on top of Power Drive and remove Power Drive from pipe.
MAINTENANCE OF POWER DRIVE
Motor Brush Replacement
Warning: To reduce possibility of electrical shock and accidental starting always
unplug power cord before servicing. Check Motor Brushes every 6 months and
replace Brushes when they are worn to less than 1/4" (6 mm).
The unit is designed to be maintenance free apart from the motor brushes which
will wear. All other maintenance should be performed by factory approved service
stations. Permanent oil filling - no maintenance required.
TROUBLE SHOOTING

- overload because of dull dies
- bad quality or insufficient thread
cutting oil
- abnormal heating of the motor - overload because of dull dies
- insufficient cooling air
- sparks forming at the motor - dirty commutator
- bad contact between brushes
and brush holder
- because of excessive wear
brushes do not touch
commutator properly
- brushes of different manufacture
- sharp edge of brush
- "sparks" in the motor - particles come loose from
compartment brushes or armature
(collector) and start glowing
- die head does not start - dull or broken dies
threading - machine running in wrong
direction
- damaged thread - dull dies
- dies not assembled in correct
sequence
- low quality pipe
- bad quality or insufficient
thread cutting oil
- support arm turns while - support arm jaws dirty
threading
- die heads cannot be changed - burr has occurred at the spline
properly end of the die head
- die head not held tightly - retaining spring damaged
or worn
