Max puls

Maximum number of impulses, at exceeding this number of impulses (before reaching
cut value) the tool will shut-off and the tightening will be judged as NOK

1 ~ 70

30

Min puls

Minimum number of impulses, if the tool shuts-off before this number of impulses
(reaching the cut value) are made the tightening will be judges as NOK.

1 ~ 70

2

Slow Error Impulses:

Tool will shut-off after making more than 70 impulses, including those below start value. The tightening will be judged as NOK (Slow error).

YZ-T setting procedure:

Please set the parameters with the PC-1 as below:

Start value : 10
Switch value : 10
Cut Value : 150
Max Value :150
Average: 3
Low speed : 300 rpm
Middle speed: 3000 rpm
High speed: 4800 rpm
Min impulses: 2
Max impulses: 70​

Make a test cycle, be aware the tool will only shut off automatic after the maximum number of 70 impulses, please release the trigger at the moment the socket doesn't rotate anymore.

Torque measuring / checking can be done with a torque wrench or rotary transducer on the actual application. Please make at least 2 cycles and check the torque in the joint before making any
changes in the adjustment or settings.

Please start with the relief valve at minimum setting to prevent damage to the product with a too high torque.
Set the torque higher if needed by the relief valve.
If torque is OK please check the value with PC-1 in Test Mode.
Set the Cut value according the stabilized value found with the test mode.
Adjust the relief valve just a little higher or set the high speed a little higher.
Set the minimum and maximum number of impulses according the hardness of the application.
Set the start value and the switch value according the hardness of the application.

The number of impulses:

In order to get a good quality joint with the correct clamp-force and a good repeatability, a certain number of impulses should be made, this number of impulses depends on the kind of joint
(hard or soft). ​

For a hard joint 6 – 10 impulses and  a soft joint 12 – 40 impulses depending on the softness of the joint.

Changing the speed and or the cut value will have an influence on the number of impulses.

​For Yokota impulse wrenches we advise to do a preventive oil change maintenance after 250.000 cycles. 1 cycle is 0.5 seconds impulsing (hard joint). Oil change is including replacing the service
kit.

Maintenance:

Check the tool regularly for loose bolts/screws or parts.

Measure the rpm of the tool regularly, in case of higher or lower rpm than indicated in the technical specifications: Stop using the tool immediate and have it repaired.

In case of power loss: Have the tool repaired.

Only trained and qualified engineers are allowed to adjust or repair the tool.

The tool should be maintained regularly to minimize the noise emission and occurring vibration.​

The speed can be changed between 4800 rpm and 2000 rpm. Push the button until 2 short beeps and 1 long beep, release the button and the speed is changed.

In the inspection mode parameter can’t be set, rundown history and pulse data will not be stored.

To cancel the inspection mode take off the battery. After replacing the battery the tool is back in normal operation mode.

Buzzer Sound and LED lightning patterns.

Warning LED Pattern.
