Warnings and Cautions: Safety First

!

 

▲ WARNING 

Never use a hydraulic torque wrench without a hydraulic gauge to indicate the working 

pressure. 

▲ WARNING 

To avoid personal injuries and/or equipment damage, be sure that all hydraulic 

components are rated for 10,000PSI (700bar) operating  pressure. 

▲ WARNING

DO NOT  exceed the allowable maximum torque of the hydraulic torque wrench. 

 

▲ WARNING 

Immediately replace any worn or damaged parts with new manuafactrer parts.

 

 WARNING

WARNING

 

To avoid personal injuries, equipment damage and/or warranty invalidation: 

 

DO NOT remove the shroud from the hydraulic torque wrench.

 

DO NOT modify any component of the hydraulic torque wrench.

 

DO NOT adjust the hydraulic torque wrench safety relief valve located inside the swivel 

couplings. 

▲ WARNING 

Always use a pin to lock the socket with the square drive in order to avoid the socket 

from falling off or damaging the square drive.

 

 

▲ CAUTION 

Keep all hydraulic torque wrench components away from excessive heat, flame, moving 

machine parts, sharp edges and chemicals.

 

▲ CAUTION

 Avoid sharp bends and kinks when routing the hydraulic hose assembly. A bent or 

kinked hydraulic hose assembly will cause severe back-pressure. This will also damage 

the internal lining of the hose leading to premature failure. Replace a kinked or damaged 

hydraulic hose assembly immediat ely.

▲ CAUTION 

DO NOT drive over, crush or drop heavy objects onto the hydraulic hose assembly. Crush 

forces may damage hose wire strands and applying pressure to a damaged hose 

assembly may cause it to rupture. Replace all crushed hydraulic hose assemblies 

immediately. 

ATWS 

Series Hydraulic Torque Wrench

 

 

Only use a high quality socket. The socket must measure up to standard ISO-2725 and 

ISO-1174 or DIN3129 and DIN3121 or ASME-B107.2/1995. Never use a chrome plated 

socket.
