MAINTENANCE
It is essential that the machine is properly maintained. Always inspect before
use. Any damage should be repaired and faults rectified. The machine
requires very little maintenance other than the following guidelines.
IMPORTANT - Disconnect from mains power before cleaning.
1. Vacuum clean any dust or shavings that accumulate in or on the motor.
2. Check all cables periodically for security, and that they are in good
condition and not cracked.
3. Check tightness of mounting bolts.
4. Check drive belt for wear and replace if frayed or otherwise damaged.
5. Periodically lubricate the tail-stock, copy stock and tool carrier screw
threads with engine oil such as SAE30 grade if they become stiff to use.
6. Lightly lubricate the tail-stock and tool-post locking handles with oil if they
become difficult to use.
• The ball bearings in the headstock and tail-stock spindles and in the copy
live roller pin are greased and permanently sealed at the factory and
require no further lubrication.
REPLACING THE BELT
1. Undo the retaining screws and
remove the belt guard.
2. By pushing the speed control
lever, expand the two halves
of the driven pulley (31)
allowing the belt to adopt its
smallest diameter at this end.
3. Rotate the motor pulley (18/
19) to dismount the drive belt
from it and then lift it off the
driven pulley.
4. Replacement is a reverse of
the removal procedure. A
broad-bladed screwdriver or
similar will be useful to prize the two halves of the motor pulley apart
against the pressure of the spring (17). Ensure the left & right halves of the
drive pulley spring back to grip the belt and that the belt is in tension.
In case of problems refer to TROUBLESHOOTING on page 16. If you are unable
to rectify any faults, please contact your local dealer or Clarke International
Service Department on 0208 988 7400 for assistance.
