Description

Riser Gear - Roller

This measuring bar is applicable only to the Roller mode. It includes three ranges, namely α, β, and γ, in green, yellow, and red, respectively.

It determines the side of the riser facing up.

For example, if the perimeter of a material is within range α, place the raisers with side α facing up when raising xTool M1 up. 

Riser Gear - Chuck

This measuring bar is applicable only to the Chuck mode. It includes two ranges, namely β and γ, in yellow and red, respectively.

It determines the side of the riser facing up.

For example, if the perimeter of a material is within range β, place the raisers with side β facing up when raising xTool M1 up. 

Rotary Attachment Gear - Roller

This measuring bar is applicable only to the Roller mode. It includes three ranges, namely A, B, and C, in green, yellow, and red, respectively.

It determines the level of the adjustable roller.

For example, if the perimeter of a material is within range A, set the adjustable roller to level A. 

Examples

Roller Mode

When using the Roller mode of RA2, you need to find out the range of the perimeter of the material on the Riser Gear - Roller and Rotary Attachment Gear - Roller measuring bars.

As shown in the preceding figure, the perimeter of the material is 180 mm, falling in range β on

Riser Gear - Roller and in range B on Rotary Attachment Gear - Roller. Therefore, to process the material, you need to place the risers with side β facing up and set the adjustable roller of RA2 to level B.

Chuck Mode

When using the Chuck mode of RA2, you need to find out the range of the perimeter of the material on the Rotary Attachment Gear - Roller measuring bar.

As shown in the preceding figure, the perimeter of the material is 180 mm, falling in range β on

Riser Gear - Chuck. Therefore, to process the material, you need to place the risers with side β facing up.
