The bar threader requires 220-240 volt, 3 phase power.
A four pronged plug (as shown) is standard.
After connecting the power be sure the head of the bar
threader is rotating in the direction indicated by the red 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
21
Adjust table height, with built in jack, to match elevation of
the bar.
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 per set 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 automated bar threader is capable of threading rebar
sizes # 3, # 4 (10M), # 5 (15M) and # 6 (20M).

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.

Prior to threading, the oil must be added. Pour the oil
onto the chip funnel and it will flow into the oil reservoir.
Only part #ELOIL should be used.
Change Control Key
To change the control key, remove the support rod screw,
compression spring, and the support rod from the head.
The reservoir is properly filled when the oil is just below
the chip drawer sliding brackets.

Slide the key out. Each key is marked with the bar size it is
to be used with in millimeters.

Slide in the new key and replace the spring, support rod and
support rod screw. Replace and tighten the back bearing.

Before installing the chasers make sure the woodruff key
(ELMP223) is tight. Press on both ends of the woodruff key
with an allen wrench, it should not move.

Take the hold down pin (ELMP203PIN) and place it through
the hole of the chaser as shown above.
To replace a woodruff key, set the key into the slot
by hand and drive into position using a hammer
and punch.
10
Insert the chaser pin into the top hole of the holder and push
down, making sure that the woodruff slot aligns with the
woodruff key, until the chaser sits completely flush on the
holder shelf.

This is what a chaser looks like when it is installed correctly
onto the holder.
