7.4 SPINDLE SPEED SELECTORS
Main spindle is variable from 30-2200 RPM,
divided into two groups, low and high speed. Low
speed ranges from 30 - 405 RPM, and High speed
ranges from 165 - 2200 RPM.
First, put the upper right-hand handle (A) on the
Headstock to needed speed range.
Note: Don’t change handle’s position with spindle
in motion. Spindle must be motionless when
changing the handle’s position.
Then, adjust Variable Speed Selector (B) to needed
spindle speed. Selectors (B) can change speed
while spindle is rotating.
Spindle Speed Chart (C) equipped on the face of
the Head- stock shows the RPM (rev/min) while
spindle is rotating.
HIGH SPEED (165-2200 RPM)
LOWER SPEED (30-405 RPM)

levers is shown below.
The B position of lever (Y) can provide a range of
