Long-reach or deep sockets are not recommended for use with hydraulic torque tools because they
can make the wrench and socket unstable. However, some applications demand the use of long-reach
sockets. When long-reach sockets are used, support for both the socket and reaction facility must
be provided. The same applies to socket accessories, such as extension bars, knuckle joints (not
recommended), etc.
Safety
The TWHC hydraulic torque wrench is a high-power hydraulic tool. It is strongly recommended that
all users are fully trained and competent in the use of hydraulic torque wrench systems. Incorrect use
of the equipment or failure to follow any of the safety precaution included herein could lead to serious
injury.
NOTE: The TWHC torque wrench is designed for torque tightening of engineering nuts only. Do
not use it for any other purpose.
• Never exceed the hydraulic torque wrench maximum working pressure of: Advance 690 bar (10,000
psi) and Retract 103 bar (1,500 psi).
• Keep hands and fingers clear of the hydraulic torque wrench head and reaction pad area, before and
during operation.
• Keep other personnel clear of the working area and only allow trained personnel to use the
equipment.
• Before operation, verify all hoses and equipment are in proper working order. Verify all hydraulic
torque wrench components (i.e. square drive, reaction arm, etc.) are properly attached and secure.
Verify the square drive retainer button is properly located.
• Do not strike any of the components, including the socket, to shock the nut free.
• Verify reaction structures are strong and rigid enough to accept the torque tool reaction forces. Do
not use wedges, packing pieces, etc. as temporary reaction structures.
• If backing wrenches are used, keep hands and limbs well clear of the backing wrench.
• Do not tighten any equipment while under pressure. Do not move or rotate the multiswivel manifold
while under pressure.
• Verify that any sockets to be used with the hydraulic torque wrench are of impact quality and capable
of withstanding the full torque output of the tool.
• Some hydraulic torque wrenches weigh in excess of 20 Kg (44 lb). If necessary, lifting equipment
can be used.
• In some instances, it may be necessary for the operator to support the hydraulic torque wrench while
it is tightening, i.e. upside-down operations. If the hydraulic torque wrench cannot be strapped into
position using ropes, etc., the operator must take care to avoid pinch points.
• Verify hoses are in good condition and undamaged. Do not bend hoses beyond their safe bend
radius limit or kink the hose.
• Never use the hydraulic torque wrench with just one hose connected to the Advance port (Port A).
This will cause the pressure to intensify within the retract chamber possibly leading to tool damage.
Always verify that both hoses are correctly connected.
• Take care when handling equipment. Quick connect couplings are especially susceptible to knocks
and damage and therefore care must be taken. Note that damaged couplings are difficult to connect.
Do not force couplings.
