Setup, Compatibility & Care
To prepare the tool, open the powder port on the side of the housing and fill it approximately two-thirds full with the provided chalk powder; avoid overfilling to prevent jamming the internal gears. When using the tool, ensure the line is taut before snapping to get the crispest result. After finishing your project, avoid reeling the line in while it is heavily covered in wet mud or debris, as this can introduce contaminants into the internal mechanism. Occasionally inspect the string for signs of wear and keep the exterior of the casing wiped down to maintain the grip surface.
