Description The Cherry G750A hand hydraulic riveting tool provides the versatility of a pneumatic-hydraulic riveter but with the lightweight, high pull strength ratio not found in other hand riveters. It has a unique 2-stage hydraulic power cylinder that provides the user with the ease of pulling the handle without the strain normally endured to install a high strength fastener. This patented 2-stage power feature allows the user to squeeze the handle throughout the increase power requirement, without feeling the need to squeeze harder to install the fastener. The Cherry G750A hand riveter can install a variety of blind fastener styles, diameters, head configurations, and material combinations without changing the pulling head or adjusting the tool. With the standard pulling head it can install CherryMAX ® and SST ® blind rivets in -4, -5, -6, diameters. It is also capable of installing -8 dia CherryMAX ® , -04, -05, -06 dia. MaxiBolt blind bolts or threaded inserts by simply changing the pulling head. Specifications Weight 1.9 lbs. Stroke .750" Pulling Capacity 3800/4400 lbs. Overall Height 6.4" Overall Length 7.5" Fluid used Use automatic transmission fluid Type “A” (no substitutes). CHERRY® recommends using ATF, Dexron III oil.

1. For CherryMAX ® and Maxibolt Use HOW TO USE THE G750A A. Make sure tool is configured to the correct fastener. See pages 4, 9 & 10. B. The piston should be fully retracted by depressing the return valve on the left side of the tool. Caution: Jaw damage may result if the piston is not fully retracted before installing a rivet. TIP: When reattaching the H750A-456 pulling head to the G750A, it is necessary to align the jaws, first pump the handle several times. Second, place a rivet stem into the H750A-456 pulling head. Last, fully retract the piston while the rivet stem is in the H750A-456 pulling head. C. Insert the rivet into the nosepiece of the pulling head, then insert the rivet into the prepared hole. D. Cycle the tool until the rivet stem breaks. TIP: Using short strokes makes it easier to operate the tool. E. Depress the return valve allowing the piston to fully retract, permitting the stem to fall from the front of the tool. 2. Use with the threaded Insert “Rivnuts” A. Be sure you have the proper size adapter for the threaded insert to be installed—the difference is the pull-up stud and the anvil. See page 10. B. If tool is of pressure regulator type 750-112 (see pg.6), adjust the pressure regulator by loosening the locknut on the right side of tool. Rotate counterclockwise, all the way out. This will leave the pressure regulator wide open—no pulling action will take place. C. Screw the threaded insert into the pull up stud. D. Place the threaded insert into the prepared hole in a test plate of the proper thickness. E. Rotate the knob of the pressure regulator clockwise in small increments and begin cycling the tool. You will notice the insert starting to collapse. The amount of upset will be determined by the amount of pressure established by the control valve. You can fine tune the adjustment until the proper upset is achieved. At this point, lock in the setting with the locknut. F. The tool is now ready to be used in a production environment and will perform consistently. 3
