E.2 ADJUSTMENT OF THE LATHE
The main spindle has been adjusted correctly before leaving the factory and you are not re-
quired to make any adjustment. However over the life of the machine it may be necessary to
adjust the spindle to correct the bearing tolerance. If adjustment is required then tighten the
spanner nut until tight then back the nut off half a turn. Ensure that the spindle turns freely. If it
doesn’t then back the nut off until it does. (Fig. 8)

E.2.2 Adjustment Of Clearance Between The Top Slide, Worktable And Cross Slide

The clearance of the top slide and cross slide have been adjusted before leaving the factory. If
any adjustment is required, please make the change by adjusting the wedges and nuts as per
the instructions shown in the picture below. The clearance is very important for the accuracy
of the lathe. Ensure that the adjustment is not too tight as this could cause the slideway to
wear unevenly making it difficult for the carriage to move; If there is too much clearance in
the slides, this will cause the tool to be pushed away or towards the work piece when taking
a cut and also cause chatter and inaccuracy. After making the adjustment take a trial cut to
determine if the finish cut on the work piece has improved. A magnetic base and dial indi-
cator can also be used to check the lateral movement of the slides. . The places to adjust are
pictured below. (Fig. 9)
