FAQ
How does this wrench differ from the 3/4" model?
The 1" square drive is standard for tools for heavy vehicles and industrial machinery. 1" sockets are larger and more durable than 3/4". Both models have the same 2034 Nm break-away torque.
What air pressure is needed?
The recommended operating pressure is 6.2 BAR. A standard workshop compressor meets this requirement.
What is the air consumption?
8 CFM (226 L/min) — a compressor with a minimum 50L tank can operate this wrench without interruptions.
Is there a warranty?
Yes — JBM is covered by the manufacturer's warranty. We handle warranty claims in Poland.
How is the speed adjusted?
6 speed levels are adjusted with a switch at the back of the tool. You can adapt the torque to a specific operation instead of always using the maximum.
