FAQs
What is the maximum torque the AT004 can produce?
The tool can produce up to 30 ft/lbs (approx. 40Nm) via air power and up to 100 ft/lbs manually.
What size sockets does this air ratchet use?
It uses standard 1/4" drive sockets.
What air pressure is recommended for optimal performance?
The recommended operating pressure is 90 PSI, with an average air consumption of 5 CFM.
How long is the AT004 air ratchet?
The total length of the tool is approximately 7 inches (180mm).
Can this tool be used without an air compressor?
Yes, it can be used manually to apply up to 100 ft/lbs of torque, but its primary function is as an air-powered tool.
What type of air inlet does it have?
It has a 1/4" BSP air inlet, which is a standard size for pneumatic tools.
Is this tool suitable for heavy-duty applications?
It is best suited for medium-duty tasks and working in tight spaces. For very heavy-duty applications requiring higher torque, a larger drive size or a more powerful impact wrench might be necessary.
Troubleshooting
Tool not engaging or running slowly
Check air pressure (should be ~90 PSI) and ensure the air hose is securely connected. Verify the air inlet is not blocked. Oil the tool's air inlet if it hasn't been done recently.
Low torque output
Ensure air pressure is adequate. Clean any debris from the drive mechanism. Use the manual torque capability for higher torque needs if air torque is insufficient.
Leaking air
Inspect the air inlet fitting and hose connection for leaks. Check O-rings and seals for damage and replace if necessary.
Ratchet mechanism feels stiff
Apply a few drops of pneumatic tool oil into the air inlet and run the tool briefly to distribute the oil. Clean any external debris from the ratchet head.
