7.2 CLEANING THE MACHINE
*Notice items:
1. Before operating any controls, remove the anti-rust
coating on all slideways and other places.
2. When cleaning, use mineral spirits or kerosene,
instead of cellulose solvents, which may damage the
paint finish.
3. Oil all brightly machined surfaces immediately after
cleaning. Apply machine oil on slideway and heavy oil
or grease on the end gears.
4. It is recommended that all slideways, the leadscrew
and feedshaft are lightly cleaned (a bristle paint brush
is useful for this).
!
Do not use compressed air to clean the machine.

7.3 LUBRICATION CHECKS
Headstock/Gearbox/Carriage, Apron/Tailstock
Refer to Figure 11.
Before operating the machine, make the following import-
ant checks:
• The headstock is filled to correct level marked on oil
sight window with Shell Tellus oil 32 or equivalent.
Check oil weekly and change the oil every 6 months.
• The gearbox is filled to level marked on oil sight
window with Shell Tellus oil 68 or equivalent. Check
oil weekly and change the oil every year.
• The carriage apron is filled to level marked on oil
sight window with Shell Tellus oil 68 or equivalent.
Check oil weekly and change the oil every year.
• There are two oil balls on the tailstock and two oil
balls on the bracket.
• Add No.68 oil 3 c.c. to them respectively every day
before operating to ensure the smoothness of ways.
• There are three oil balls on the cross slide and top
slide.
• Add No.68 oil 10 c.c. to them respectively every day
before operating to ensure the smoothness of lead
screws.
A manually operated one-shot lubrication pump (A) is
incorporated into the apron, and draws oil from the apron
reservoir.
It enables the operator to ensure that the slideways are
kept adequately lubricated. The pump should be operated
before and occasionally during the work period.
