Before taking into use

Read and understand the contents of this manual before installing, operating, repairing, maintaining, changing accessories this tool. Only qualifi ed and trained operators should install, adjust or use the too.

Charging the battery

Slide the battery in the charger, this should go smoothly otherwise the alignment isn‘t correct or the battery / charger grooves are damaged. In that case check the battery and charger and replace the damaged item, do not repair.

Cool down the charger when charging more than two battery packs consecutively. Do not insert your fingers/ nails into contact hole, when holding charger or any other occasions. Place charger in a relatively cool and well-ventilated area.

Plug charger into the AC outlet. CAUTION: Ensure that the power source to be utilized conforms to the power requirement specified on the product nameplate. If the red power light does not light immediately or goes out soon after the charger is plugged in, consult an authorized dealer.

During charging, the charging light (green) will start flashing. When charging is completed, an internal electronic switch will automatically be triggered to prevent overcharging. Charging will not start if the battery pack is warm. For example, immediately after heavy-duty operation. The yellow standby light will be flashing until the battery cools down.

Once the battery is fully charged, the green lamp will be lit to indicate the charger is in float charging mode.

Fasten and secure the reaction arm on the jagged side of the gearbox with the retaining ring.
Spread the retaining ring open with a screwdriver and place the open side in the groove at the end of the gearbox.
Then gradually press the retaining ring until it is completely closed.
To remove the reaction arm, place a screwdriver at the beginning of the retaining ring and spread the retaining ring open. Then pull the retaining ring off and remove the reaction arm.

Movement of the reaction arm

Installing the reaction arm

Ensure the reaction arm and retaining ring are installed securely to hold the reaction arm in place. Make sure the reaction arm is in contact with a solid reaction point before you operate the tool. When the tool is in operation the reaction arm rotates in the opposite direction to the output square drive and must be allowed to rest squarely against a solid object or surface adjacent to the bolt to be tightened, see Figure 2
Installing the reaction arm

WARNING: In use, this tool must be supported at all times in order to prevent unexpected release in the event of a fastener or component failure!.

Reaction arm height

Ensure the height of the socket is even with the height of the reaction arm as seen below in Figure 3A. The height of the socket cannot be shorter or higher than the height of the reaction arm as seen below in Figure 3B and 3C.

Torque adjustment

Remove the battery before adjusting.
Pistol model: open the cover. Insert the adjust wrench in the shaft and rotate The SDM Battery Series are calibrated on one pre-specified torque setting, multiple torque settings are not possible. If you need a different torque we advise to send the tool back to RAD Torque Systems B.V. to make the adjustment and recalibrate the tool. However, the torque adjustment can be done as follow: hole is seen. Push the adjust wrench in the hole and rotate the adjust wrench.
Angle model: open the cover. Use a wrench to rotate the shaft until the adjust hole is seen. Push the adjust wrench in the hole and rotate the adjust wrench.
Clockwise = increase torque output, counterclockwise = decrease torque output.

Please not: you need a calibration form to verify the new torque …
Torque adjustment

SDM calibration

NOTE: Only one target value can be set and calibrated at this tool.

The repeatability can be filled out on the special SDM Calibration Template.

Connect the tool to the calibration system and perform a first pull.
The torque value after this pull determines whether more or less torque is required. If more torque is required, use the calibration tool the to turn a few clicks clockwise. If less torque is needed, use the calibration tool to turn a few clicks counter clockwise.
This torque value must be checked every time after taking a few clicks, by making 1 or 2 pulls.
Be careful with the amount of clicks when approaching the maximum torque of the gearbox, to avoid over torque.
When target torque is achieved, perform 5 pulls to validate.
These 5 torque values can be filled out on the SDM Calibration Template together with all the other information regarding the gearbox, handle and the transducer.
A calibration sticker needs to be applied to the gearbox with a 1 year validation.
Save the template as a file for future reference and print and laminate a copy of the certificate for the costumer.

Preparing

Ensure the entire calibration system is ready, clean and checked (bolt, grease, washers and transducer).
Ensure that the calibration certificate of the transducer has not expired.
Ensure the SDM is properly mounted together with the special bracket to the motor drive unit.
Ensure the battery is fully charged.

NOTE: Make sure the spring inside the tool is NOT tensioned too high before performing the first pull in order to prevent over torque and damage to the gearbox.

Please see picture below

Open the cover to access the spring. Turning the motor in order to find the opening which fits the Philips-head calibration tool.

Use the calibration tool to relieve spring tension by turning/clicking counter clockwise.
