OPERATING INSTRUCTIONS FOR THE T-7891A RIVET TOOL
-
Maintain fluid levels – Use 30 wt. oil. There are two methods of adding oil to the T-7891A.
A. PREFERREDWAY: Mount tool in vice with bottom cap # 35 up. Remove #35 with wrench #55. Remove entire piston (part #29, 30, 31, 32, 33, 34) as an assembly, by grasping #33 with a pair of pliers and pulling straight up. After the piston is removed fill with 30 weight non detergent oil to top of #40 nut (no oil should be in the #39 cylinder). Replace #35 Cap, and remove tool from the vice. With the tool in the upright position, remove #13 screw and excess oil will be vented. Wipe away excess oil, and replace #13. The total amount of oil should be 1/2 tablespoons.
B. Mount the T-7891A in a vice in the upright position, using cardboard or cloth to prevent marring the finish. Remove #13 oil fill screw. Remove01A, B, C or D nosepiece. Screw in #49 bolt plug with #57 hex wrench to open
the oil passage. Gradually add oil through the vent opening. Replace the fill screw #13. Remove #49 and replace with #01 nosepiece. Remove fill screw #13 to vent excess oil. (Too much oil in the system can cause a failure of the housing). A few drops of 30 wt oil or air tool oil through the air inlet every 10 to 15 minutes is recommended if no air line oiler is in place.
-
Adjusting the stroke – Remove #02 by using #55 wrench. For maximum stroke, loosen nut #08 and thread the nut all the way onto #17 piston. Then loosen #03 and #07 and thread them all the way to #08. Hold #08 with a wrench and tighten #3. For a shorter stroke, adjust #08 so that it is away from the shoulder of #17 by two or more threads, depending on how short you want the stroke to be.
-
Always use the correct size nosepiece for the rivet you are using. It is a good idea to use a silicone oil such as WD 40 to lubricate the jaws #04 when pulling quantities of rivets, as there may be a build up of metal particles that could cause mandrels to stick in the jaws.
-
Air pressure – The maximum pressure should be 90 PSI. A higher pressure could cause damage to your tool. Using the lowest pressure possible for your appplication will extend the life of your tool dramatically.
-
As with all tools, make sure that all parts are tight from time to time, as vibration from use may loosen components.
-
Mandrels – The T-7891A comes complete with the #22 mandrel catcher. Once a rivet has been popped, and the next rivet is mounted in the nosepiece, the last mandrel will slide into the #22. To remove mandrels, turn the tool upside down and they will fall out of the slot in #22, or remove #22 completely and empty.
