PULLING HEAD SELECTION FOR BLIND FASTENERS
•The lists given below are for reference only; for more up to date and detailed information, please check on the
Cherry Aerospace webpage as following: Installation Tooling Manuals(links to current tool manuals) and
Product Expert (interactive database for tool recommendations)
INSTALLING THE PULLING HEAD ON RIVETER
1. Place anvil (B) into nose piece (C)
2. Pry the bottom leaf spring open, with the help of a flat
screwdriver, far enough to insert the anvil and nose
assembly. Release the leaf spring and allow it to snap
over the nose assy.
3. Remove the set screw (20) and thread the jaw holder
assembly (A) into upper frame (using flat wrench
690A62 included with tool) to about 1/16” protrusion
behind the upper frame.
4. Thread screw (20) back in without tightening; the pulling
head must be adjusted following the directions below.
5. In case an extension nose piece is being used (for example P/N H690-4C-15/16”) there is an additional part
(ring, shown in dotted line). This ring must be placed on top of the anvil (B) / nose piece assembly before
being placed into the leaf spring.
In this case, is advisable in this case to loosen the screws holding the leaf spring rather than forcing it open.
PULLING HEAD ADJUSTMENT
6. Prior to installing fasteners, the pulling head must be setup using the setup gages provided with the riveter.
The gages are color coded as following:
•Green for the -4 diameter, (P/N 628-4)
•Red for the -5 diameter (P/N 628-5)

LOCKRING ANVIL SETTING ADJUSTMENT
Note: All the item numbers refer to the exploded view from page 10.
1. Insert the short end of the setup gage into the nosepiece (C).
2. Loosen the Jam Nut (item 29) so set screw (item 28) can be
adjusted.
3. Thread the set screw (item 28) in or out until top of the gage is
flush with the gaging surface
4. Tighten the Jam Nut (item 29) while holding the Set Screw
(item 28) to prevent it from rotating.
SHIFT POINT SETTING
Before starting this set-up, make sure that the set screw (20) is loose.
1. Select the appropriate diameter gage and push the long, serrated end into the nosepiece (C); if the gage
falls freely,
2. Unthread (turn counter-clockwise) the jaw holder (A) with tool 690A62, until the gage pin get stuck inside the
nosepiece
3. Loosen the grip slightly by threading the jaw holder (A) in (turn clockwise) about a quarter turn.
4. Tighten the set screw (20).
To verify setup, install fasteners in a test plate; the fastener stems should break relatively flush with the top of
the rivet (see applicable procurement specifications). If high or low stem protrusion is observed, loosen the set
screw (20) and turn the jaw assembly holder (A) one-quarter of a turn at a time, in either direction, until desired
flushness is obtained. The position of the anvil (see above procedure) may also need to be fine-tuned.

PRIMING AND BLEEDING THE TOOL
After service, the riveter must be primed with hydraulic fluid before re-assembling the head
cylinder.
•Stand the base upright and fill the base handle (56) with fluid up to the top then
assemble and tighten the manifold.
•Stand the base upright with the hoses and head assembly above it and connect to an
airline. Caution: The tool will automatically trigger, so hold the head assembly firmly.
•Remove the screws (38) and (47) from cylinder (36) and manifold (49).
•Using a pressurized fluid source, circulate fluid until the it drains smoothly with no air
bubbles out of the bleed hole (where screw 38 was)
•Thread the screws back in and cycle the tool a few times to make sure it functions
properly.
•Redo this procedure if necessary to remove all the air pockets from the hydraulic fluid.
BLEEDING INSTRUCTIONS
This operation should be done as part of regular tool maintenance in order to replenish the
hydraulic fluid and remove the air bubbles from the hydraulic fluid.
What is needed:, an 1/8” Hex Key; 700A77 Bleed Bottle
•Place the hand held unit over an oil drip pan and remove the side Screw (38);
•Attach the Bleeder Bottle 700A77 and place the hand held unit in a vise making sure that
the bleeder bottle is upside down and it is the highest point of the system.
•Cycle several times; air bubbles from the system will be pushed up into bleed bottle,
being replaced by hydraulic fluid. Continue cycling until no more air bubbles are
released into the bottle.
•When done, carefully remove the bleed bottle and replace with Screw (38).
•Test for correct function; re-set if necessary.
TROUBLESHOOTING GUIDE
Should the riveter not operate properly,
1. Check that the tool is connected to an airline and the air pressure is within the recommended limits..
2. Bleed the system to eliminate air and replenish fluid.
3. Check for oil leakage.
a) Leakage around the cap screw (38) indicates that the screw is loose or the gasket (37) needs replacing.
b) Leakage through the by-pass hole at the base of the handle (56) indicate that the O-Rings (75) are worn or damaged.
4. Operate the trigger repeatedly to determine that it is working properly; this can be done by listening to the tool as the trigger is
depressed and released. If the valve is working properly the air piston (80) and power piston (52) can be heard traveling inside
the tool.
5. Check the piston stroke. If the tool is short of stroke, it may need to be serviced or at least bled properly.
6. Make sure the set screw (20) is tightened; if it gets lose, the jaw holder setting drifts during operation incapable of holding setup.
If the riveter still fails to operate properly, it may need to be serviced; we recommend contacting one of our authorized US or
international repair centers (http://cherryaerospace.com/contacts/distributors#tool-repair-us or
http://cherryaerospace.com/contacts/distributors#tool-repair-intl)
