  If the TKR Group Rivet Tools pump isn't running, first ensure compressed air is connected. Check that the control lines are correctly connected and properly seated. Verify sufficient air pressure from the air supply and that the air pressure is correctly set. Also, confirm the hydraulic hose is connected as described in the instruction manual. If none of these resolve the issue, the drive plunger may be defective, requiring repair through the manufacturer.

Why won't the hydraulic pump on my TKR Group PNP 90 SNW-RIV Rivet Tools shut off?

  If the hydraulic pump on your TKR Group Rivet Tools won't shut off, check that the control hoses are correctly connected. If the hoses are fine, the issue may be defective control valves, which require repair through the manufacturer. Also, inspect the rivet mandrel or rivet die for defects or adhesive residue; replace or clean them as needed. Insufficient press pressure, caused by too little or incorrectly set air pressure, or too little oil in the pump, can also prevent shutoff. Check the oil level and top up if necessary. If there's an oil or air leak from the pump, it needs repair through the manufacturer.

  If the rivet plunger on your TKR Group Rivet Tools travels too slowly or not at all, start by checking the oil level in the pump and topping it up if necessary. If the oil level is sufficient, the hydraulic seal or valves in the pump may be defective, requiring repair through the manufacturer.
