Operation
Installing or removing the battery
To remove the battery, slide the red button on the front of the cartridge and withdraw it from the tool. To insert, align the tongue on the battery with the groove in the housing and slide it into place until it clicks.
Switch action
The trigger switch controls the tool. The reversing switch changes the direction of rotation. Always set the reversing switch to the neutral position when the tool is not in use.
Speed change
Switch off the tool before changing speeds. Slide the speed change lever to '2' for high speed or '1' for low speed.
Adjusting fastening torque
The torque can be adjusted in 18 steps by turning the adjusting ring. Align the desired number with the pointer on the tool body. Use lower settings for smaller screws and higher settings for larger screws or harder materials.
Drilling and hammer drilling
For drilling, set the ring to the drill mark. For hammer drilling (walls), set the ring to the hammer mark. Do not use the hammer mode when drilling in wood or metal.
Maintenance
Keep the tool clean and free of oil and grease. Never use gasoline, benzene, thinner, or alcohol for cleaning as these may cause discoloration or cracks. If the tool is operated continuously until the battery is discharged, allow it to rest for 15 minutes before using a fresh battery.

Common problems
Tool stops working during operation
The battery may be discharged or overheated. Allow the tool to rest for 15 minutes or recharge the battery.
Drill bit slips in the chuck
Ensure the bit is inserted straight and the chuck is tightened securely by turning the sleeve clockwise.
Tool damaged or overheating
Do not force the tool. Use the correct speed and torque settings for the application.
Before use
- Ensure the battery is fully charged.
- Check that the reversing switch is in the neutral position when not in use.
- Verify the correct speed setting (1 or 2) is selected.
- Ensure the correct torque setting is selected for the material.
- Check that the drill bit is securely tightened in the chuck.
Specs in practice
- No-load speed
- The rotational speed of the chuck without a load. 0-450 rpm is for low speed/high torque, 0-2000 rpm is for high speed.
- Torque setting
- Adjustable clutch settings (21+3) to control the force applied to screws, preventing over-tightening.
