MEET WAKIT GRINDERS (1st design) Note: Wakit Grinders KLR is the new version. The 1st Design Wakit is a rechargeable electric herb grinder with patented ball & chain technology that grinds herb, the size of a nickel, to a coarse consistency with 1 to 2 quick short taps. HOW TO USE Wakit Grinder is incredibly easy to use, for everyone, and there is no assembly needed. Simply place herb, the size of a nickel, on the tray and place Wakit Grinders on top. Depending on herb using 1 to 2 quick short taps will provide a coarse texture. If you like a finer grind, simply add another quick short tap. Before lifting the unit, allow 1 second for the momentum of ball and chain to cease. WARNING: Do not use herb larger than a nickel size, as the ball and chain mechanism needs space to spin. If you place herb larger than the recommended size, the built-in safety mechanism will sense the resistance causing it to shut down the motor for 3-5 seconds. The motor will automatically reset again. The Wakit KLR Series has a stronger motor, if you require more torque. WARNING - Keep fingers and all body parts out of the ball and chain grind chamber during use.
