NOTE: The working depth can be set in 1 mm increments.
NOTE: The working depth figures should be used just as a guideline. Depending on lawn or soil conditions, the actual working depth may become slightly different from the set depth.
NOTE: Try a test operation in a less conspicuous place to get the desired depth.

NOTE: When you turn the adjusting dial to the right and set it to the lower scale of the machine, the working depth is set to -12 mm. If the set working depth cannot be obtained when you set the adjusting dial to the lower scale of the machine depending on the conditions such as lawn environment or wear of scarifier blades, you can operate the machine with a setting one step deeper by turning the adjusting dial to the right beyond the lower scale.
