9. REFERENCE MATERIALS
9-1. Speed Control Mechanism
Spindle rotation speed of the Model DS 12DVB2 can be
controlled by simply varying the amount by which the
trigger switch is depressed. The relationship between the
amount the trigger switch is depressed (in millimeters) and
the rotation speed is illustrated in Fig. 3.
Note: The gradient and values illustrated in Fig. 3 are
intended for reference only, and will vary slightly
due to differences in the discharge condition of the
battery, the ambient temperature, and individual
speed-control element accuracy.
