8.13Checking center alignment

When the headstock is returned from outboard position, the alignment between centers should be checked.

1.Lock the headstock in normal spindle turning position.

2.Slide the tailstock toward the headstock until the centers almost touch (see Figure 18). Lock the tailstock in position.

3.View the center points from top and side to make sure they align.

4.If the centers do not align, unlock the headstock and pivot it slightly. There should be enough “play” in the headstock to adjust for this alignment. Lock the headstock when finished.

9.0Operating controls

Refer to Figure 19.

On/off switch (A): Pull to start lathe, push to stop. The safety key (A1) can be removed to prevent unauthorized use of lathe. The safety key must be inserted to restart the lathe.

Figure 19

If a power outage should occur during operation, the lathe will immediately restart when power is resumed if the start switch is still engaged. Push switch immediately to OFF position in the event of a power outage.

Speed control handle: Rotate handle (B, Figure

20)to set speed, which is displayed as RPM (revolutions per minute) in the adjoining window

(C).

Do not start lathe at maximum speed when a workpiece is mounted in the lathe. Start at lower speed and gradually increase to desired speed.

Figure 20

The JWL-1440VS contains a Reeves or “split- pulley” system.

As speed is increased, via the speed change handle, the spindle pulley widens and the belt drops down to the smaller diameter between the pulley halves. Conversely, the motor pulley, which is spring-loaded so that it adjusts automatically to the movement of the spindle pulley, gets narrower, drawing the belt outward toward the larger diameter. When the speed is decreased, the pulleys act in opposite fashion.

Change speed while the lathe spindle is turning to avoid overstressing the belt.

10.0Operation

The information which follows is general in nature and not intended to be a complete course in woodturning. Nothing can replace the knowledge gained by talking with experienced woodturners or consulting books or trade magazines. Above all, simple trial and error will aid in developing proficiency in the craft.

10.1Inspection

Before operating the lathe, check that everything is in proper working order:

1.Level your machine; use the leveling feet to help reduce vibration.

2.Check bearings; adjust only if endplay exists.

3.Check belt; it should be snug but not overly tight.
