move each unit (table and ram) to the opposite 
limit stop, and clean and lubricate the newly 
exposed ways. Loosen bolts to unlock ram and 
move it forward and backward to the full length 
in order to clean and lubricate. 

7.  Cover all machined surfaces with a film of light 

machine tool oil to inhibit rust. 

8.  Remove wood block from below knee. 

Some of the following steps may have already

cross-feed handle on their respective shafts. 
Tighten each handle using a wrench on the 
flats. 

10.  Remove any rust proofing from drawbar. Install 

drawbar with its washer into spindle center 
through top of head assembly. When installing 
tool into spindle, lock spindle and tighten 
drawbar using provided wrench.  

11. Slide the fine feed handwheel over the hub 

and push it back until its roll pin engages hole 
in hub, and handwheel is flush with hub 
surface. 

12. Place coarse feed handle on feed shaft,
