Electrical

1

The bar threader requires 220-240 volt, 3 phase power. A four-pronged
locking plug (as shown) is standard.

2

After connecting the power be sure the head of the bar threader is rotating
in the direction indicated by the arrow on the hood. If it is not rotating in
the correct direction, switch any two of the power leads in the plug.

Center Rings

1

Adjust table height, with built-in jack, to match the elevation
of the bar.

2

To obtain the best centering of the rebar into the threading
machine, the best fitting set of center rings should be used.
We offer two or three different size sets per bar. To make sure
you are using the correct set, slide one of the center rings over
the bar ends to be threaded to determine which one slides
on easily with the least amount of slop. Each center ring is
stamped with the bar size it is to be used with in millimeters.

The bar threader will ship set up to run the largest bar size
you will be threading.

5

When threading a #14 (43 mm) or #18 (57 mm) bar, the
adaptor ring must be removed. This is done in the same way
you remove the center ring. See the previous step.

43

To change centers to a different bar size or to go with a set
that fits the bar better, push in the release ring and pull out
the existing center. Put in the new center and lock it in place
by letting loose of the release ring.

Add Oil

21

Prior to threading, the oil must be added. Pour the oil
into the chip funnel and it will flow into the oil reservoir.
Only part #ELOIL oil should be used.

The reservoir is properly filled when the oil is just below
the chip drawer sliding brackets.

Threading Operation

21

Prior to positioning the rebar in the machine, be sure that the
machine carriage is all the way back to the right.

Position the bar stop so that it covers the hole in the faceplate.
Butt the rebar up against it. This helps assure the correct bar
placement into the bar threader.

Also be sure that the step drum is in the correct starting notch.

43

Once the bar is in position tighten the vise. Make sure the vise
is tight to prevent bar rotation during threading.

65

Move the bar stop away from the bar. Turn on the machine. Hood must be in the forward position

before the machine will start. The number I button is slow speed
which is used when threading #14 (43 mm) and #18 (57 mm)
bar. The number II button is high speed to be used for #11
(36 mm) and smaller bars.

www.erico.com

15

Threading Operation

87

Make sure oil is flowing into the head of the bar threader.
If it is, then with the right hand handle move the body of
the bar threader forward. Apply pressure on the handle once
the cutters are in contact with the bar, for at least one-half
turn of the handle. After this initial engagement the body of
the machine will move forward automatically.

9

Holding the machine carriage all the way back, move the step
drum to the next forward notch. Refer to reference chart for
number of passes.

Once the body of the machine stops moving forward it is
time to again move the machine carriage all the way back
to the right.

10

After the last threading pass, move the machine carriage all
the way back to the right.

11

Position the control ring in the same notch you used for the
first pass. The bar threader is now ready for the next bar.

16

Checking Threads and Bar End Engagement

21

The thread profile should be checked with a brand new chaser. To check the length of the thread, slide the bar end gauge

over the bar and look to see if the end of the bar falls within
the step range of the gauge.

NOTE: More detailed thread inspection procedures
can be found in the LENTON® product document:
Bar Fabrication Procedures (PDF118).

3

If the length of the thread is off in step 2, the adjustment
screw below the motor is used to make up the difference.
Turning it in (counter-clockwise), makes the thread longer;
turning it out (clockwise), makes the thread shorter.

If the length of the thread is off, the proper adjustment can
easily be made by measuring the amount of protrusion from
or recession into the gauge.

Example: If the bar is protruding beyond the gauge by
1/8 inch you would turn the adjustment screw in (clockwise)
so that the machine body would move forward 1/8 inch.
If the bar was 1/8 inch too short you would turn the screw
out (counter-clockwise) moving the body of the machine
back 1/8 inch.

A scrap piece of bar should be used to set the bar end
gauge prior to making a production run.

Maintenance

21

Machine chips are caught in the screened drawer above the
oil reservoir. The drawer should be emptied as required during
the machining run and at the end of the day.

The oil is drained by loosening and removing the drain plug
at the bottom of the oil reservoir. A bucket and crescent
wrench is provided to accomplish this.

Let the oil sit in the bucket overnight to allow the metal
fines to settle out. Next morning, slowly pour the oil back
into the bar threader and clean out the bucket.

At the end of each day 15 minutes should be put aside to
drain the oil and clean out the oil reservoir.

3

After the oil is drained, a piece of cardboard or putty knife
can be used to scrape the chips out of the oil reservoir.
