6) Using the lock handle, adjust the marker on the threading dies head to match your pipe size Shown on the scale in Figure 6, then

lock the handle in place. Figure 6. Close up of scale and maker used for setting pipe sizes.

Locking/ Unlocking Pipe in headstock To lock a piece of pipe in the headstock 1) Open both chucks on the headstock by rotating them, and insert the pipe through the support

chuck. 2) Center the pipe in the support chuck and close it. 3) Close the hammer chuck until it grips the pipe evenly with all jaws, then open it about a

1/4-1/2 turn, and slam it closed, as shown in Figure 8, to lock the chuck on the pipe. Note---When threading a short pipe that does not reach the support chuck, hold and center The pipe by hand until the hammer chuck is tightened.

Figure 7. (Slamming hammer chuck to lock it on the pipe)

7

To unlock a piece of pipe:

1) Slam the hammer chuck toward the rear of the machine to open the chuck. 2) Hold the pipe in one hand and open the support chuck with the other. 3) Remove the pipe

Cutting/Squaring Pipe The cutting attachment provides a quick and easy way of cutting pipe to length or squaring off the end of a pipe before cutting threads. To cut/square a piece of pipe 1) Move the cutter, threading tool, and reaming tool out of the way of the work area. 2) Insert the pipe in the headstock, pull it under the cutter, and lock it in the headstock. 3) Lower the cutter over the pipe, position the cutter with the carriage handle, and tighten the blade

down lightly on the pipe. 4) Turn the pipe threader ON 5) Slowly increase cutting pressure with the cutting handle until the cut is complete and the end of

Pipe falls off. Figure 8 shows an example of a cutting operation.

WARNING!

Because of the cutting pressure , pipe ends may pop into the air when cut off. Wear safety

glasses and avoid standing to the right of the machine when cutting

Figure 8. Cutting/squaring the end of the pipe

7) Apply enough pressure on the carriage handwheel for the dies to engage the pipe for about three or four threads, then release the carriage handle. A standard taper thread will continued to cut until finished. 8) When the threading tool roller drops down over the end of the taper block, the dies will open

and the threading is complete. 9) Turn the pipe threader OFF and retract the carriage until the threading dies head clears the

threaded pipe. 10) Pull the lock pin out and raise the threading tool. 11) Ream the end of the pipe, as described on this page.

Reaming

Rough pipe ends must be reamed after they are cut or threaded to avoid sharp ends that cause lacerations when handling. Reaming is usually performed when the pipe is still locked in the headstock after cutting or threading.

To ream the pipe end 1) Make sure the pipe is locked in the headstock. 2) Turn the pipe threader ON. 3) Move the reaming tool down and lock it into position.

4) Turn the carriage handwheel to slowly move the reaming tool into the pipe and cut off the sharp edge. Figure 11 shows an example of a reaming operation

Figure 11 (Typical reaming operation)

5) Turn the pipe threader OFF

6) Using the carriage handwheel, move the reaming tool back and then lift it out of the way. 7) Make sure the pipe has come to a complete stop, then remove it from the headstock.

SECTION 5. MAINTENANCE

WARNING! Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury.

Schedule For optimum performance from your machine, follow this maintenance schedule and refer to any

specific instructions given in this section.

Daily

Clean drip tray and bed. Make sure that cutting fluid flows freely, by testing the flow with threading dies head in both

up/down positions.

Weekly

Clean the fluid screens and grime pot. Evaluate the condition of the fluid; change if necessary.

Make sure fluid tank is 3/4 full by removing the drip tray and plastic liner and visually

inspecting.

Lubricate the spindle bearings through the two ports on the headstock..

Monthly

Clean/lubricate the cutting tool rollers and blade. Lubricate the carriage shaft.

Cleaning Drip Tray & Bed The drip tray is the removable metallic tray that the fluid flows onto and the bed is the body of the

machine that surrounds the drip tray and also collects some metal particles and fluid.

12

To Clean the drip tray and bed: 1) Raise all the tools for easy access. 2) Wipe down the bed with a dry rag, brushing

an chips/shaving into the drip tray.

3) Remove the tray ( Figure 12), properly

dispose of chips/shavings, and clean the tray.

Figure 12 (Removing drip tray)

Fluid Screen & Grime Pot There are fluid screens located in the drip tray and directly above the grime pot. The grime pot is located directly under the drip tray in a plastic liner. Clean the screens and grime pot with a dry

rag ( or use a solvent tank if available, then wipe dry) To Clean the fluid screen and grime pot: 1) Clean the drip tray and bed, but do not replace the drip tray when you are done. 2) Clean any metal shavings from the edges of the plastic liner so they do not fall into the reservoir

when the liner is removed. 3) Lift the plastic liner (Figure 13 ) out of the fluid reservoir.

4) Remove the screen from the plastic liner by rotating it to align the screen tab with the liner slot

as viewed from the underside in Figure 14

13

5) Clean the screen and the grime pot ( Figure 15 )

6) Clean any remaining metal shavings from the edges of where the plastic liner was mounted in

the reservoir.

7) Install the screen in the plastic liner and replace the plastic liner and drip tray above the fluid

reservoir, as shown in Figure 16

14

Figure 16. Clean drip tray and screens reinstalled.

Cutting Tool Rollers & Blade

To clean and lubricate the cutting tool rollers and blade:

1) Raise the cutting tool

2) Remove the cutter pins from the end of the roller shafts and pull the roller shaft out of the

housing ( see Figure 17 for parts identification)

3) Clean the roller shafts, rollers, blade, and housing. 4）Coat the roller shafts with high-temp grease and insert them into the rollers and blade, as shown

in Figure 18, to spread the grease.

15

Figure18 5) Finish the job by replacing all the cutter components removed in step 2. To Lubricate the carriage shafts: 1) Pour a liberal amount of cutting/tapping fluid on the front carriage shaft, and move the carriage

back and forth several times 2) Wipe up excess fluid with a dry rag, and use the fluid on that rag to coat the rear carriage shaft,

adding more if necessary for a thin coat of coverage.

Checking Fluid Flow If the fluid flow gets restricted or blocked, troubleshot and fix it before performing any thread

cutting operations or dies will be quickly ruined.

To Check the fluid flow: 1) Move the threading dies up and start the motor, Fluid should flow freely in the location shown

in Figure 19 Figure 19. Fluid flow location with threading dies up

16

2) Move the threading dies down and start the motor. Fluid should flow freely where shown

In Figure 20

Figure 20. Fluid flow location with threading dies down

Changing Fluid

Very small metal particles will accumulate in the tank and could eventually clog the pump if the

fluid is not changed on a regular basis. When fluid becomes discolored or contaminated with small

metal particles, clean the tank thoroughly and refill it with clean cutting fluid. Checking the fluid

is a sample procedure that requires a sheet of clean white paper.

To change the cutting fluid: 1) Place the fluid pan under the reservoir and remove the drain plug shown in

Figure 21

Figure 21

Figure 21 Location of drain plug

2) After the reservoir has drained, clean the intake screen (access by removing screw and pivoting screen up) and the bottom of the reservoir, as shown in Figure 22

17

Figure 22, Intake screen lifted for cleaning

3) Pivot the intake screen back down and fasten it to the bottom of the reservoir with the

screw. 4) Replace the drain plug and pour in approximately 1/2 gallon or more cutting and tapping

fluid.

5) Replace the plastic liner, the liner screen, and the drip tray.

Lubricating Spindle Bearings

To Lubricate Spindle Bearings: 1) Lubricate as shown in Figure 23

Figure 23. Location of headstock oil ports 2) Place five drops of oil in the fluid ports. 3) Turn the motor ON and allow it to run for approximately 30 seconds to disperse the fluid.

18

SECTION 5. SERVICE

Repairing Clogged Pump Very small metal particles will accumulate in the tank and could eventually clog the pump if the

fluid is not changed on a regular basis. If the pump stops working and you have verified that there

are no other obstructions in the fluid lines，then the pump may need to be repaired. Repairing the pump is an easy job that takes approximately 10 minutes, and should only be done

after the fluid has been changed.

To repair a clogged fluid pump: 1) Remove the motor access cover (Held in place by two screws) to expose the fluid pump, as

shown in Figure 24. 2) Unbolt the three hex bolts on the pump cover and carefully pull the cover off.

3) Using the pliers, pull the pump shaft out of the pump, as shown in Figure 25

4) Using the rag and solvent/degreaser, clean the pump shaft and the inside of the pump to remove

any built-up grime or metal chips. 5) Inspect the O-ring that was between the pump and the pump cover.

If the O-ring is hard, cracked, or otherwise in poor condition, replace it( for quick turnaround, new O-ring can often be found in hardware or automotive stores ). If the O-ring is soft, pliable, and in otherwise good condition, reuse it.

6) Lubricate the pump shaft in the same manner as you removed it, and replace the pump cover and access cover to complete the job.
