How to use

Install a compatible ProCORE18V or other Bosch 18 V battery and secure it in the tool. Select the appropriate user mode (metal mode A or wood mode B) on the interface and choose one of the three speed/torque settings according to the fastener size and material. Fit the correct socket or bit to the 3/4" tool holder and seat it firmly. Apply the impact driver to the fastener and operate the trigger, monitoring the LED tool status indicator. For maximum performance on demanding tasks use ProCORE18V batteries with at least 5.5 Ah capacity.

Recommendations

Use metal mode (A) for bolts and standard metal fastening and wood mode (B) when working with lag screws or wood fasteners to reduce the risk of broken screwheads. Regularly check battery charge and use batteries and chargers from the Bosch Professional 18 V system. Observe safety instructions for torque-controlled tools and wear appropriate protective equipment during operation.
