Ridge Tool Company • Elyria, Ohio • U.S.A.14

Threading Pipe Using No. 141 Geared

Threader (Close Coupled Method)

1. Install pipe in threader and center end of pipe in

throat of dies. Tighten workholder with socket

wrench.

2. Plug in power cord.

3. Turn power drive REV/OFF/FOR switch to FOR

position.

4. Step on foot switch.

5. Flood dies with RIDGID Thread Cutting Oil during

threading operation to assure long die life.

6. Release foot switch when red stop line appears

on pinion sleeve.

NOTE! RIDGID geared threaders are jam proof designed

so that pinion shaft will automatically disengage

if threader is accidentally run on pipe past a full

thread length.

7. Turn REV/OFF/FOR switch to REV (reverse)

position.

8. Step on foot switch and reverse threader one or

two revolutions. Turn REV/OFF/FOR switch to

OFF position.

9. Pull cam plate knobs and rotate cam plate as far as

it will go towards CD mark on head to disengage

dies.

10. Using the socked wrench, loosen jaw clamp screw,

turn workholder to OPEN position and remove

pipe.

NOTE! Before threading next piece of pipe, run threader

head beyond STANDARD line on pinion sleeve

and then back to standard line. This movement

takes up slack in gearing for immediate

response when cutting next thread.

Maintenance Instructions

WARNING! Always unplug power cord before servicing

machine.

Oil Flow Control Valve

NOTE! The flow of oil out of the die head can be in-

creased or decreased by adjusting oil control

Lubrication

Proper lubrication is essential to trouble-free opera-

tion and long life of threading machine.

Two grease fittings are provided on top of machine

housing to allow for oiling of the front and rear bear-

ings (Figure 22).

NOTE! Bearings should be greased periodically,

depending on usage of machine.

Oil System Maintenance

To help assure proper operation of threading mach-

ine, keep oil system clean, as follows:

1. Replace thread cutting oil when it becomes dirty or

contaminated. To drain oil, position a container

under the drain plug and unscrew plug.

2. Keep oil filter screen clean to assure proper flow of

clean oil to work. Oil filter screen is located in the

bottom of oil reservoir. Do not operate machine

with oil filter screen removed.

NOTE! Do not disassemble oil pump. Pump should be

disassembled only by a RIDGID Authorized

Service Center.
