Product description
The jigsaw features an adjustable stroke rate, orbital action, and a Cut Control system for precise cutting. Key components include the blade holder, base plate, battery release button, and dust extraction port.
Assembly
- Battery: Insert the charged battery into the battery holder until it clicks into place.
- Blade Installation: Use protective gloves. Move the blade holder upwards, insert the blade (teeth facing the cutting direction) until it stops. Ensure the back of the blade sits in the guide roller groove.
- Dust Extraction: Connect a vacuum hose to the extraction port if needed.
Operation
- Switching On/Off: Press the lock-off button, then press and hold the on/off switch. Release the switch to stop.
- Stroke Rate Control: Adjust the stroke rate by varying the pressure on the on/off switch.
- Orbital Action: Use the adjustment lever to set the orbital action. Lower settings provide cleaner cuts; higher settings provide faster cutting speeds.
- Cutting Angle: The base plate can be tilted up to 45° to the left or right for bevel cuts.
Maintenance
- Regularly clean the blade holder by tapping the tool on a flat surface.
- Lubricate the guide roller occasionally with a drop of oil.
- Keep ventilation slots clean to ensure proper motor cooling.
Troubleshooting
