4. Setup
4.1 Battery Charging and Installation
Ensure the battery pack is fully charged before initial use. Use only the charger specified by Bosch for 14.4 Volt Li-ion batteries. To install the battery, align it with the base of the drill driver and slide it in until it clicks securely into place. To remove, press the release button and slide the battery out.
4.2 Attaching Drill Bits or Screwdriver Bits
The drill driver features a 1.5 - 13mm chuck clamping range. To attach a bit:
- Rotate the chuck counter-clockwise to open the jaws.
- Insert the desired drill bit or screwdriver bit into the chuck.
- Rotate the chuck clockwise to tighten the jaws firmly around the bit. Ensure the bit is centered and securely held.
5. Operating Instructions
5.1 Power On/Off and Speed Control
The tool is activated by pressing the trigger switch. The speed is variable, controlled by the amount of pressure applied to the trigger. The drill driver offers two no-load speed settings: 0 - 500 rpm (1st gear) for higher torque applications and 0 - 1600 rpm (2nd gear) for faster drilling.
5.2 Forward/Reverse Rotation
A selector switch located above the trigger controls the direction of rotation. Push the switch to the left for forward rotation (for drilling and driving screws) and to the right for reverse rotation (for removing screws or freeing jammed bits). Ensure the switch is in the neutral (center) position when not in use to prevent accidental starting.
5.3 Torque Settings for Screwdriving
The Bosch GSR 14.4 VLi features 18+1 torque settings, allowing precise control for various screwdriving tasks. Rotate the torque collar to select the desired setting. Lower settings are for smaller screws and softer materials, while higher settings are for larger screws and harder materials. The '+1' setting is for maximum torque, suitable for drilling.
- Maximum torque for hard screwdriving applications: 60 Nm
- Maximum torque for soft screwdriving applications: 25 Nm
5.4 Drilling Applications
When drilling, ensure the torque collar is set to the drill symbol (maximum torque). Apply steady, even pressure and allow the drill to do the work. The maximum drilling diameter in wood is 32mm, and in steel is 13mm.
