The HT-6750 is a hydraulic tool designed to set from 1/8 inch up to and including 1/4
inch diameter steel, stainless steel, aluminum and plastic rivets by changing only the nose
piece. The HT-6750 has a rated pull pressure of over 3,500 lbs and one handed operation
gives access to tight areas.
The hydraulic system is sealed, oil need not be added. If the HT-6850M should become

OPERATING INSTRUCTIONS
The HT-6750 hydraulic riveter installs fasteners by a pull and release system. Pumping the handles (see fig.
2 on the next page) will actuate the tool. The tool must be actuated when installing fasteners or changing nose
pieces. After installing the fastener or changing the nose piece, the tool must be returned to its original
position. This releases the pintail if a fastener was installed. To do this point the tool downward, squeeze
HANDLES and push in RELEASING BUTTON (see fig. 3). The pintail should drop out. (See sections on
NOSE PIECE INSTALLATION and FASTENER INSTALLATION for detailed instructions.)
Nose Piece Installation:
SELECT THE PROPER NOSE PIECE
FOR THE CORRECT INSTALLATION OF
FASTENER AND FUNCTION OF TOOL.
To change the Nose Piece
1. Remove the NOSE PIECE in the
tool by unscrewing it in a
counterclockwise direction.
2. Actuate tool until it is fully extended.
(There should be gap of approximately
7/8" in between the RESERVOIR
SHIELD and the TOOL BODY. (see
fig. 1))
3. Hand tighten the NOSE PIECE into
the NOSE TUBE and release the tool
by squeezing the HANDLES and
pressing the RELEASING BUT-TON
at the same time.
Fastener Installation:
Install correct nose piece on tool (see NOSE
PIECE installation section).
1. Insert pintail of rivet in to the NOSE
PIECE.
2. Position the RIVET BODY in to WORK
PIECE to be fastened.
3. Hold the tool steady against the work
piece and pump HANDLES until rivet is
set and pintailis broken*See fig. 2 on the
next page.
*The HT-6750 has a 5/8 inch work travel and will set most rivets in one cycle (approx. 12 pumps). If the tool
reaches the end of its travel before the rivet breaks, DO NOT continue pumping the HANDLES on the tool.
Release the tool by squeezing the HANDLES and pressing the RELEASING BUTTON, regrip the rivet, pump the
HANDLES and finish the installation.
Note:
Before operating tool, make sure that all NOSE PARTS have been
screwed in HAND TIGHT.
Frequently check that nose components do not vibrate loose
during operation. ng

Three Piece Jaw Installation and
1. The jaws are installed at the factory and should only need to be removed for periodic inspection and cleaning. To
remove the jaws unscrew the NOSE TUBE from the tool in a counterclockwise direction.
2. THREE PIECE JAW SYSTEM
Remove the JAW HOLDER by unscrewing it in a counterclockwise direction. Drop JAWS out
from SPRING side. Actuate tool by squeezing the ACTUATING TRIGGER (see fig 3 above)
until the jaw pusher is fully extended. Stop as soon as the JAW PUSHER is in the extended
position.
3. THREE PIECE JAW SYSTEM
To replace JAWS, hold JAW HOLDER large end down and at a slight angle. Hold finger over
small opening and place jaws in one at a time. Add a small amount of jaw lubricant to jaws and
jaws holder prior to assembly.


4. When jaws are in place, insert jaw holder into spring, being sure to keep large end of jaw holder pointing downward.
5. THREE JAW SYSTEM
Hold tool with the PULLER SHAFT pointing down and the JAW PUSHER fully
extended. Screw the jaw holder on to the PULLER SHAFT. HAND TIGHTEN
ONLY.
6. Replace the NOSE TUBE and NOSE PIECE, HAND TIGHTEN ONLY. The tool is now ready to use.

TROUBLESHOOTING
Problem Solution
1 . Rivet pintail is stuck in tool
First Step:
Lightly tap nose against a hard surface while after
breaking squeezing HANDLES and pressing down the
RELEASING BUTTON with tool pointing downward
Pintail should then fall out, see fig. 4. (If that does not
work try Second Step)
Second Step: (Use this only if first step does not work)
Remove NOSE TUBE and JAW HOLDER (for help see
figure 5) take out pintail and reassemble.
2. Tool will not reverse
Push on the handles until you feel a slight give,
then press the RELEASING BUTTON and continue
pushing on the handles, the tool should then reverse. If
this does not work Remove NOSE TUBE and inspect
for any foreign matter that may have cause the jamming
between JAW HOLDER and the inside of NOSE TUBE.
3. Fastener does not pull rivet
The JAW HOLDER is loose. Remove the NOSE TUBE
and tighten the JAW HOLDER by turning it
counter clockwise (see (See Three Piece Jaw
Installation and Removal)).
4. The rivet does not fit into the tool
The rivet is to large, or the wrong NOSE PIECE is on
the tool. To find the correct NOSE PIECE (see chart on
page 11). If you do not have the needed NOSE PIECE,
See next page for how to order the correct one.
5. Premature breaking
See solution for problem 4. Also verify the grip of the
fastener and make sure you are not rocking the tool
during installation.
6. Jamming of tool
See solution for problem 4. Also verify that you have the
proper jaw engagement and that all parts are hand tight
and that the jaws are cleaned and properly assembled
in jaw pusher (See Three Piece Jaw Installation and
Removal)
7. Rivet not installed properly See solution for problem 4. Also verify jaw grip and that
the appropriate fastener is being used.
8. Jaws breaking See solution for problem 4. Check to see all parts are
properly assembled and hand tight.
9. Damaged jaw pusher See solution for problem 4. Check to see if all parts are
properly assembled.
