BIT AND SLEEVE INSTALLATION:
1. Remove the tool from the box.
2. Install a Bit and Sleeve. Follow installation instructions below.
(Bits and Sleeves are sold separately. See page 5 for bit and sleeve
selection).
*Loosen nose piece (nut).
*Insert the bit into the nose
piece
* Rotate until the bit is
seated on the driver.
*Place sleeve over the bit
and slide the sleeve into
the nose piece. Rotate the
sleeve as you are sliding
the sleeve into the nose
piece until the sleeve has
engaged with the collet
pin, the sleeve will then
slide further into the
nose piece. The sleeve is
now seated.

*While squeezing the trigger, tighten the nose piece. This will
insure proper orientation of the bit and sleeve and will minimize
drag on the trigger.
*The tool is now ready for use. To make a wire wrapped connection
follow the instructions and helpful hints on the pages ahead.

Some Hints on Making Wrapped Connections
Easy Does It!
Do not press too hard. Let the OK tools
do the work. Excessive pressurecan
lead to overwrapping. Backforce "BF"
to prevent overwrapping is available
on most power tools and is recom-
mended for use with 26
through 30 AWG wire.
Feed Wire Correctly!
It’s easy to feed wire into the slot in
the OK bit correctly. Be sure the
stripped end of the wire is “pushed-in”
all the way.
Stay With It!
Just keep the OK tool on the terminal
until the wrap is complete. Early
removal can result in spiral and open
wraps.
Use the Correct Bit and
Sleeve!
Wire wrapping is a precision technique
and the wrong bit and sleeve just can-
not do the job. Improper selection can
cause problems ranging from “Pigtails”
to loose wraps.

Maintenance Procedure:
Manual Wire Wrapping Tools
Periodic Maintenance:
The only required maintenance is periodic greasing of the gear
assembly. The interval is dependent on use. For reference we suggest
every 50,000 wraps or every 6 months which ever comes first.
Tools Required:
1. Philips Head Screwdriver.
2. Synthetic Grease (Such as: Chemplex 940 from NFO Technologies).
Disassembly:
1. Using a Philips head screwdriver, remove the 5 screws that hold the
housing together. Note the type and location of the screws.
2. Turn the gun over and lay it down on a flat surface so the nose
piece is facing left. Separate the housings and remove the collet and
nose piece. Note: Use a flat head screwdriver to separate the hous-
ings.

3. Apply grease
to the bevel,
spur and face gear.
Reassembly:
1. Prior to closing the unit the bit index must be checked.
2. Load a bit into the barrel assembly.
3. The wire slot on the bit should be in the 12 O’clock position. If the
wireslot is not in the 12 O’clock position then proceed to step 4.
If the wireslot is in the 12 O’clock position then proceed to step 5.
4. Lift the barrel assembly from the gun assembly and rotate the bit
until the wire slot is in the 12 O’clock position. Reinstall the barrel
assembly into the gun housing. Insure the barrel-locating pin is
seated into its locating hole in the housing and that the bit is still
in the 12 O’clock position.
5. Reinstall top housing and Install the bottom 6-32x5/8 screw. Install
collet and nose piece, insuring that the colet-locating pin is seated
in the locating hole in the housing. Install remaining screws.
