4. Operating Instructions
4.1 Variable Speed Control
The jig saw features a variable-speed trigger, allowing you to control the strokes per minute (SPM) from 0 to 3,000. Press the trigger lightly for slower speeds and harder for faster speeds. This enables optimal cutting performance across various materials and applications.
Figure 4: The variable speed trigger provides enhanced control for different cutting tasks, from delicate curves to aggressive straight cuts.
4.2 Orbital Action Settings
The 4-position orbital action lever allows you to adjust the aggressiveness of the blade's stroke. Higher orbital settings (e.g., 3 or 4) provide faster, more aggressive cuts suitable for wood, while lower settings (e.g., 0 or 1) offer smoother, slower cuts ideal for metal or fine finishes.

4.3 Bevel Adjustments
The all-metal keyless shoe bevel allows for quick angle adjustments. It has detents at 0°, 15°, 30°, and 45° for common bevel cuts. To adjust, loosen the shoe bevel lever, tilt the shoe to the desired angle, and then tighten the lever to secure it.
