DESCRIPTION
The Cherry G715A Pneumatic-Hydraulic
Riveter is designed specifically for the most
efficient installation of Cherry Rivets. It weighs
only 4 lbs. and can be operated in any position
with one hand.
The G715A Riveter is 10-5/8"high, has a 1-
1/8" stroke and generates a minimum of 1400
lbs. of pull on 90 to 110 psi of air pressure at the
tool. See chart on following page for tool
capacity.
PULLING HEADS
Pulling heads are not furnished with this tool but must be ordered separately.
In ordering heads be sure to specify the shank diameter and head style
(universal or countersunk) of the rivets to be installed.
The following pulling heads will fit directly on the G715A Riveter:
G6H Series .... For installing 100, 200, 300 and 500 Series Knob Stem Cherry Rivets.
H80 Series ..... For 600, 700 and 800 Series High-Clinch Cherry Rivets.
H615 Series ... For 2000 Series Locked Spindle, Flush Fracturing Cherrylock Rivets.
H9015 Series . For 9000 Series Serrated Stem Cherry Rivets.
INSTALLING PULLING HEADS ON RIVETER
1. Engage threads of pulling head inside nose fitting (1)
and turn head clockwise until the threads bottom out.
2. Tighten jam nut to lock pulling head in desired position.

MAINTENANCE AND REPAIR
The G715A Riveter has been manufactured
to give maximum service with minimum care.
In order that this may be accomplished, the
following recommendations should be
followed.
1. The hydraulic system should be full of oil
and free from air at all times.
2. Keep excessive moisture and dirt out of the
air supply to prevent wear.
3. Do not pound on the rear of the tool head to
force rivets into holes as this will damage
the tool.
4. Make sure the pulling head is correctly and
securely attached.
TO FILL RIVETER WITH OIL
1. Connect the tool to an air line and remove
the cap screw (5) located on the side of the
head.
2. Using a pressure oil can filled with DEXRON
III Automatic Transmission Fluid, Type A (no
substitute), force the fluid into the head until
filled. It may be necessary to turn tool upside
down to insure head is filled with fluid.
3. Replace the cap screw, cycle the trigger
several times and then repeat steps 1 and 2
above.
4. To insure the positive removal of ALL air from
the hydraulic system, we recommend the
use of Cherry Air Bleeder No. 700A77.

Seller warrants the goods conform to applicable specifications and drawings and will be manufactured and inspected according to generally accepted practices of
companies manufacturing industrial or aerospace fasteners. In the event of any breach of the foregoing warranty, Buyer’s sole remedy shall be to return defective
goods (after receiving authorization from Seller) for replacement or refund of the purchase price, at the Seller’s option. Seller agrees to any freight costs in
connection with the return of any defective goods, but any costs relating to removal of the defective or nonconforming goods or installation of replacement goods
shall be Buyer’s responsibility. SELLER’S WARRANTY DOES NOT APPLY WHEN ANY PHYSICAL OR CHEMICAL CHANGE IN THE FORM OF THE
PRODUCT IS MADE BY BUYER.
THE FOREGOING EXPRESS WARRANTY AND REMEDY ARE EXCLUSIVE AND ARE IN LIEU OF ALL OTHER WARRANTIES AND REMEDIES;
ANY IMPLIED WARRANTY AS TO QUALITY, FITNESS FOR PURPOSE, OR MERCHANTABILITY IS HEREBY SPECIFICALLY DISCLAIMED AND
EXCLUDED BY SELLER. THIS WARRANTY IS VOID IF SELLER IS NOT NOTIFIED IN WRITING OF ANY REJECTION OF THE GOODS WITHIN
ONE (1) YEAR AFTER INITIAL USE BY BUYER OF ANY POWER RIVETER OR NINETY (90) DAYS AFTER INITIAL USE OF ANY OTHER
PRODUCT.
Seller shall not be liable under any circumstances for incidental, special or consequential damages arising in whole or in part from any breach by Seller, AND

TROUBLE SHOOTING
1. Check air line for correct pressure at the
tool. It must be 90 to 110 psi.
2. Check tool for lack of hydraulic fluid (see oil
filling instructions).
3. Check for oil leakage.
a. Oil leaking around the cap screw (5) in
the head indicates that the screw is loose
or the washer gasket (6) needs replacing.
b. If oil should leak through the by-pass
hole at the base of the handle (15) the
O-Rings (32) are worn or damaged.
c. Oil leaking from the front of the nose
fitting (1) indicates that O-Rings (2) are
worn or damaged.
d. If head is taken apart for repair check
all O-Rings and carefully clean all parts
before reassembling. Be sure to make
any replacements with the exact O-Rings
shown in the parts list to insure that the
correct material and hardness is used.
4. Check valve for air leakage. If air is
escaping, remove retaining ring (44) and
muffler (43). Insert a 5/16-18 threaded rod
or bolt into end of valve plug (42) and pull
it out. Using the same procedure pull out
spool (40). Replace O-Rings (39 & 41) and
reassemble.
Note: It should never be necessary to remove
the valve sleeve (37) unless the air supply has
become so badly contaminated that the ports
in the sleeve are plugged up. If this
unlikelihood should occur, carefully remove
spring (38) from its groove, using extreme
caution not to distort the coils of the spring.
Remove sleeve (37), clean thoroughly,
replace O-Rings (36) and reassemble,
making sure that spring (38) is seated in its
groove correctly, otherwise valve will not
function.
5. Check movement of piston (7). If it does not
move freely or is slow in operation:
a.O-Rings (8) may be damaged and require
replacement.
b.Piston (7) may be mechanically locked
due to damaged parts.
c.Power piston may be held off its seat on rod
(35) allowing oil to by-pass. Drain tool, flush
thoroughly and refill with fresh oil.
d.Muffler (43) or air filter inside spool (40) may
be plugged with dirt. Clean them
thoroughly with normal solvent and back-
blow with compressed air.
NOTE: We recommend the purchase of a
G715KS Service Kit which contains
various gaskets, O-Rings, washers
and similar parts likely to need replacing
in time.
