IN-SAND™ Dynamically Balanced Non-Random Orbital CNC Sander with 3.5mm Orbital Stroke and 1/2" Shank
This CNC orbital sanding tool is designed to use with any 4” sanding disc (included) according with the finish required. Full set of instructions included.
UNDERSTANDING THE SANDER BEFORE USE:
The In-Sand™ sander comes with two different springs, the hard spring comes installed on the tool and the soft spring is included in the package. The springs look very similar, but by compressing the springs you can feel the difference between the stiffness of them.
A spring inside the sander ensures constant pressure is applied to the sanding pad. The amount of pressure is determined by setting the “depth of cut” in your software. Do not exceed the maximum spring compression by setting your cut depth too deep, for best results use our recommended settings.
The hard spring applies a maximum pressure of 22lbs (10kg) with a maximum compression of 0.078" (2mm). The recommended “depth of cut” setting is 0.04" (1.01mm). This spring is best used for flat surfaces. The sander should not be used to flatten surfaces, the surface must already be flat before sanding.
The soft spring applies a maximum pressure of 4.4lbs (2kg) with a maximum compression of 0.1" (2.6mm). The recommended “depth of cut” setting is 0.08" (2.03mm). This spring is best used for rough, but relatively flat surfaces. The maximum deviation in the surface cannot exceed the maximum compression of the spring. On uneven surfaces, it will follow the ups and downs of the material, which may be helpful in certain cases like using rough sawn wood where you want to smooth it out, but not remove the rough sawn look, for example.
Pad Installation & Replacement
1. Hold the spindle with the key (part #6) using the flats on the spindle.
2. Remove spindle (part #2), ring (part #3) and spring (part #4).
3. Clean out any dust and swap the spring if necessary (part #4).
4. Reassemble ensuring the ring (part # 3) is installed with the groove seated toward the top bearing of the spindle (part #2).
5. Press the spindle into housing, and tighten the screw (part #1).
6. (Part #5) helps to balance the tool. It is properly adjusted from the factory, do NOT attempt to remove it!
The In-Sand™ is a non-random orbital sander, which operates in a fixed, predictable motion. The sander is dynamically balanced from the factory, using Part #5 as the balancing element. DO NOT ADJUST THIS PART. If the red mark on Part #5 is not aligned properly to the red mark on the tool body, please contact the Amana Tool® technical support team for assistance at (800) 445-0077.
Knowing which grit sandpaper to use depends on the type of job and what step in the process you are in. The lower the grit numbers, the coarser the disc will be, and the higher the grit, the finer it will be.
