Troubleshooting Guide
Problem
Possible Cause and Solution
Excessive vibration.
Out of balance, or large work piece. Reduce lathe speed to the
lowest speed possible and turn the work piece to a true circle.
Adjusting the speed using the up / down keys will change the speed
in 10 rpm increments. If you try adjusting the speed up or down you
will find that it is easy to find speed points that will minimize vibration
and is one of the biggest advantages of DVR technology.
Work piece is not held in the center. Check work piece mounting and
correct.
Work piece is not secure or held tight enough. Check work piece
mounting.
Lathe incorrectly bolted to stand or bench. Refer to this manual for
lathe stand recommendations.
Stand or bench not well constructed, too light, or not level on the
floor. Make sure the stand is solidly constructed. Use sandbags to
weigh down the stand.
The metal floor stand should be Rawl bolted to the floor at the 4 hole
points.
Faceplate or chuck
running out of true.
Dirt build-up on the rear of the faceplates or chuck. Clean off all
build-up and dirt. Faceplates and chucks must mount securely
against the inner bearing ring surface of the spindle.
Turning tools not sliding
smoothly across Toolrest.
Damaged surface on toolrest face caused by sharp edged tools. File
the toolrest using a fine smooth file and polish with extra fine
sandpaper. Also remove the sharp edges from the corners of turning
tools.
Spur drive center or live
center not holding into the
spindle taper or quill taper
when turning.
Small end of Morse taper is damaged due to dropping or hitting. File
or polish away any damage. Check that inside of tapers have not
been scored.
Grease or oil inside of Morse tapers. Wipe clean the inside of the
tapers.
Insufficient pressure when installing the center. Use a quick, firm
action by hand to install a taper. Do not knock in using any solid
object.

Is master switch on? Toggle master switch to "ON" position.
Check machine is plugged into wall socket and switched on.
Check that the wall switch plug is live by plugging in another power
tool if the other power tool doesn't go check your board fuse.
Check the master fuse on the lower rear guard. Ensure machine

blown, replace with the spare fuse that comes with the lathe. Do not
replace with a higher amp fuse.
