I I purchase: of a HHARRISO~" lathe, !:J.1.e observance of 'yvhicn will ensure satisfactory se:-'"·lice. New developments and. modil-l.cations resultL."1g in improved perio:rma...""1c': ill2y be incorporated from time to tL,Tle on them and the right is reser;red to modify the specification as may be :-equired. The !Tillin purpose of this booklet is to provide users wit..~ a full list of par::s, should replacements become necessary. When ordering spares please quote the paz-t number~ description and the LATHE NUJ\i.BER, wt-.ich will be found stamped at the tailstock end of the bed. Attention has been drawn to a few points ?lhich may be of use to ~he JtJ S T .,~ L L f~ TEO t~ Siing;ng:

Holes are provided in the base under the ~eadstock and tailstock ttuougb. '.vhich a oar IT".1.ay be passed. for slinging p1l:poses. the macr-jne on a rigid floor. Ensure th2t me test mandrels are true, clea..'1. and free from burrs on the taper seating. Clean, and inspecr the internal taper of the spindle before inserting the mandrel. I Care should be taken to avoid the lifting ropes bearing on the lead-screw or feed ,od. DETAILS OF ANI DISCREPANCY BETWEEN THE TEST G-1P..RT AND YOUR O~ TESTS SHOULD BE REPORTED TO THE MANUFACTURERS BEFORE ANY ADJUSTMENT IS MADE. C~eaning: .('\11 bright surfaces are covered 'with an anti-corrosi~'le compound before despatch from the works.

This should be removed with petrol or para..f1in before putting the machine into operation. EtectdcaJ connection: The supply wires should De cOffilected to L.~e isolator switch at the end of the cabinet in b.'1e usual IT'.:.ar'u·.ler. Leven~i1g: Because of the rigid integrated construction of the bed and. canine: D2se the machine is inherently accurate and caDable of oerfonnance within the specification, when it leaves the works. ~ A ~nitiaj opera.tion: It is important to ma...'r.ce sure that t...~e feed or sc:rewC"utt:ng levers are in the disengaged position Defore operating the Lathe other;:;ise damage can be caused by the saddle or tools running into the headstock or tailstock.

The Iathe shouid not be boited down but should be IO'Y\;'ered on to locating pins secured to a rigid floor and the jacking screws adjusted to eli-rninate rock. By bolting JOi;v-n, distortion could occur, introducing twist in the bed and the resultant damage may not be corrected by releasing the nuts on the bolts. f...!.s the headstock is the most important unit of the Lathe only the best IT"A2teriais and workmanship are incorporated in this assembly. All the gear teeth are induction hardened to 45°:500 Brindl and honed to a smooth and accurate form. The hardening may result in a SOline. of higher pitch than is evident on a Lathe which does not have hardened gears.

It is advisable to support the jacking screws on steel plates. The screws should be ad1usted ::0 enable the he3dstock end of the lathe being slightly higher than the tailstock end so that the front of the machine is raised relative to the rear. This facilitates return of the coolant to the Slli"TIp. To ensure satisfactory operation of the bearings it is essential to run in the macl1ine at lower speeds only duriIlg the first 40/50 hours of operation. After Lhis initial run in period we also recommend that a further gradual build-up to the top speed operation is followed. Before despatch the machine has been carefully tested for smooth rUlli-llng and accuracy.

(See test chart.) Any checks for accuracy MUST be made with l. 7
