1
12 gal.
5. Run the machine for a while, with chuck and pump
motors on to warm up and distribute lubricant.
6. Chuck Speed: For the large chuck , ( 1 1(4 " capac it y) use
the slower speed , with the belt on the small motor pulley. For
the 1 11 16" chuck , use the normal speed, with belt on the
larger motor pulley. See Illustration Page 6.
To produce valves wi th a smooth, accurate finish , wet
grind all valves. Wet grinding also reduces wheel wear and
the need to redress the grinding wheel.
Keep
the chuck clean. It is advisable to place a rubber
sh ield on valve stem when grind ing to prevent the coolant
from getting i nto the chuck. Avoid splashing the coolant
away. A small stream is sufficient to keep_ the valve cool.
This
is a precision built machine. To obtain best results ,
keep it in a shop heated
to about 68°
