Question 4

The DLT1173/1673A/1973A torque checker does not turn on, how can I fix the issue?

Accepted Answer

In some cases, the CPU inside the device may not be activated when the power is on with a Ni-MH battery charged after fully discharged ( due to being left unused for a long time) and now the device is in Sleep mode.
In such a case, to wake up the device from Sleep mode you have to press the Reset button for 2 seconds.

The system will restore the initial state (all contents of memory will be deleted).

Question 5

How accurate is the torque of the Delvo screwdrivers?

Accepted Answer

Delvo screwdrivers' torque repeatability is in general about 5 to 10% accurate and this is affected by actual application.

Question 6

Is there any technical difference between TD01800 and TD08766 Delvo rotor assy for DLV7530／ 7540 ／ 7550  ／ 8530  ／ 8540  ／ 8550 -BKE ／ -MKE  ／ -PKE ?

Accepted Answer

There is no technical difference, however, TD01800 's package only contains the rotor assy while TD08766 rotor assy packed in a plastic bag with a rust preventing paper.

Question 7

Is there a vacuum pickup system for DLV7500 / 8500 series?

Accepted Answer

Unfortunately, no vacuum system is available for DLV7500 / 8500 series, neither DLP6500 nor DLP7000 can be used for DLV7500/8500.

Question 8

How to choose a suitable sleeve for the Delvo DLS sleeves for vacuum pickup?

Accepted Answer

To choose a suitable sleeve you have to consider a  sleeve with inner dia. ( = φd in the catalog) that makes a 0.1mm gap with the screw head dia./ bit dia. is the best.

In case you couldn't find a suitable sleeve for your model, please check with us about the necessity of special-made sleeves, etc.

Please include your request together with your screw drawing & bit drawing.
Countersunk screws (tend to be somewhat unstable for Vacuum Pick-up (because of the thin screw head)

Question 9

What part code do I have to order for Brushless DLV30A/45A/70A-ABK screwdrivers for changeover switch?

Accepted Answer

The changeover switch alone is not available for sales.
Customers always have to buy it as a sensor assy.

For the CHANGEOVER SWITCH,
due to safety reasons the whole SENSOR ASSEMBLY ( Lever to start: TD08225 / Push to start: TD08217 ) needs to be exchanged!

Please be noted that even exchanging this SENSOR ASSEMBLY can be difficult.
 
Is your engineer already familiar with exchanging this Sensor Assy?
He has to be careful on various points, such as below:

- Not to lose small peripheral parts ( TV07409 etc.) when disassembling.
- If screwdriver performance is strange ( repeated hitting of the clutch, rotation stop halfway before finishing screw-fastening, etc.)
after the Sensor Assy exchange, you need to adjust the sensor timing.
- When assembling, you need to apply sealing paste onto the parts to protect dust coming inside.

In case the engineer is not confident enough, either of the below could be the choice:
a. Please send the tool back to us and we’ll arrange a repair
     * Operation cost will be charged in addition to the exchange parts pricing.

b. We can work together with your engineer online (or onsite, if the conditions allow) to repair the tool correctly.
