Frequently Asked Questions - 107104 Urrea

How do I set the torque on the Urrea 107104 screwdriver?

Unlock the knurled handle by turning the lock nut counterclockwise. Then turn the handle until the zero graduation on the beveled edge lines up with the vertical mark on the case and the desired torque value, for example 480 in-lb. For 504 in-lb, continue turning until the first graduation on the handle aligns with the vertical line. Finally, lock the handle by turning the lock nut clockwise.

What is the accuracy of the Urrea 107104 torque screwdriver?

The torque wrench is calibrated to an accuracy of ±4% as stated in the manual.

How should I maintain the torque screwdriver?

Clean the wrench by wiping it with a cloth. Do not submerge it in any type of cleaner that could affect the internal lubricant.

What should I do if the wrench has not been used for a long time?

Operate it several times at a low torque setting to allow the special internal lubricant to recoat the internal working parts before use.

How do I store the torque screwdriver when not in use?

Always set the adjustment to the lowest torque setting to maintain calibration and prevent spring fatigue.

What happens if I continue pulling after the wrench clicks?

Do not continue pulling after the preset torque is reached. Continuing to apply pressure can damage the fastener or the part being torqued by applying excessive torque, and may also damage the wrench.

How often should the torque wrench be calibrated?

Calibration intervals depend on usage: less than 3 hours per week: once a year; 3-5 hours per week: every six months; 5-25 hours per week: every three months; more than 25 hours per week: monthly. Recalibrate if the wrench is dropped or abused.

Can I use extensions or adapters with the Urrea 107104?

Yes, but using an extension or adapter changes the output torque. Use the formula: TA = TW * (L / (L + A)) where TA is torque at adapter, L is distance from square drive to hand position, TW is wrench scale reading, and A is adapter length.

What is the warranty period for this torque screwdriver?

Urrea provides a 1-year warranty on parts, components, and labor against manufacturing defects from the purchase date. Present the product with the properly filled warranty to an authorized distributor.

Is the Urrea 107104 suitable for use as a conventional wrench?

No, this is a precision measuring instrument. Do not use it as a striking tool or a conventional wrench, as it may damage the internal mechanism.

WARNING: Read, understand and follow the safety rules in this instructive, before operating this tool.

ESTABLECIMIENTO DEL TORQUE

How to use your new torque SURTEK.

• Balancing wrench in left with graduations visible unlock knurled handle by turning lock nut counterclockwise see fig.1.

• Set amount of torque required by turning knurled handle to read exact amount on case graduations. Example: 504 in-lb.

• Turn knurled handle until the zero graduation on the belivel edge of the knurled handle is lined up with the vertical mark on the case, and is even with the 480 in-lb graduation.

• Turn knurled handle until 1 graduation on the beveled edge of the handle is in line with the vertical line on the case.
• Lock handle securely by tuning lock nut clock-wise. Wrench is now set al 504 in-lb. Torque and is ready to use see fig.2.

- When setting for metric (kg-m), use name procedures as setting for in-lb.

• Install the proper socket or attachment to the square drive and apply to nut or boit and pull handle until you feel and/or hear wrench click. Release pull and wrench automatically reset for next operation. Do not continue to pull after wrench releases. Use special care at low torque setting that pull stops when wrench clicks.

CAUTION

1. If wrench has not been or has been in stored for some time, operate it several times at a low torque setting which allow special internal lubricant to recoat internal working parts.
2. When wrench is not in use, keep adjustment at lowest torque setting.
3. Do not turn handle below lowest torque setting.
4. So not continue pulling on the wrench after pre-set torque has been reached and the wrench released. Pressure must be taken off the handle and the wrench allowed to automatically reset it self, continuing to apply pressure after the wrench has released, will result in damage to the part being toque by applying more than the specified amount of torque.

5. Tool is rugged and designed for shop use, but, is also a precision measuring instrument and should be treated as such.

6. Clean wrench by wiping do not submerge in any type of cleaner which may affect special high pressure lube with which the wrench is packed at the factory.

7. This torque wrench was calibrated and tested before leaving the factory and is accurate to +-4%.
8. THIS A PRESICION MEASURING INSTRUMENTS. CALIBRATION AND SERVICING MUST BE DONE REGULARY AND IS THE OWNERS RESPONSABILITY.
9. Do not apply this wrench as a striking tool or a conventional wrench.

CALIBRATION RECOMMENDATIONS.

• Less than three hour per week once a year.
- Between three and five hours per week once each six months.
- Between five and twenty-five hours per week once each three months.
- More than twenty-five hours per week once each months.
- It will have to calibrate whenever one abuses its struck use that is.
- Calibration must be done by quality personnel.

USE OF EXTENSIONS AND ADAPTERS

When using an extension or adapter (increasing the effective length of the torque wrench) the output torque value will change. To calculate the new torque output of the wrench use the formula bellow.

- A number of variables including the length of the adapter or extension, length of the wrench in variations in hand position on the wrench wheel affect the accuracy of the above calculation.

• TA = Torque exerted at the end of adapter.
• L = Distance between square drive hand position.
• TW = Wrench scale reading.
• A = Length of adapter or extension.
