When shifting to āLOā DO NOT FORCE THE LEVER if the back -gears to not
mesh. Hold the lever so that the gears are clear of one another, r otate the spindle
nose by hand until the gears line up, then put the unit in āLOā (back -gear).
500 to 4500 RPM is obtained through the direct drive and is referred to as high
range. The same procedure as above is used to select this range, except the HI -
NEUTRAL-LO lever is set in the āHIā position.
Wear on the V belt will cause a slight difference between the actual speeds and
those shown in dial windows. This can be corrected as follows: Turn the variable
resistor knob clockwise until it stops. (This will be near the 4500 reading on the
counter.) Use a tachometer to determine the spindle speed, and then adjust the
parameter value inside the inverter until the spindle speed registers 4500 on the
tachometer.
CAUTION
DO NOT SHIFT THE HI-NEUTRAL-LO LEVER WHEN
THE FEED GEAR IS ENGAGED.
DO NOT LOOSEN the 3 hex nuts on the upper part of the Quill Housing. These are
set at the factory and are used only for alignment.
SWIVELING THE VARI-DRIVE may be accomplished by loosening the lower 3
hex nuts attaching the Vari-Drive unit to the quill housing and then swiveling to
any desired position. See arrangement of T-Bolts in Gear Housing for this purpose.
CAUTION
CARE MUST BE TAKEN TO SECURE THE NUTS WHEN
THE ATTACHMENT IS IN POSITION, BEFORE THE
MOTOR IS TURNED ON.
