#4 press the cycle start button to start the hydraulic pump. Then press the grinder wheel and coolant buttons. And press the cycle start button to turn them on.

#5 adjust the stop position knobs just beyond the location of your part on the table by rotating the knobs counter clockwise to loosen, then sliding them to the desired postion, then snug them by rotating the knobs clockwise.

#6 dress thee wheel if desired, by rotating the numbered dial 2 marks clockwise, then turn the table power feed handle to point to the diamond, and pull downward on the dresser lever until the dresser is in a fully forward position, then release the lever and wait until it fully returns. Repeat until wheel is fully dressed.

#7 use the manual handles to position the grinder wheel over the workpiece, then slowly move the table movement lever to move the table back and forth and slowly lower the head until the grinder wheel gently touches the workpiece.

#8 zero the digital readout if equipped, then loosed the locking knob on the downfeed handle, and rotate the numbered ring until it reaches zero, then each small line represents a .0005" Rotate the ring clockwise the amount you want to grind off. Example: .002" would be four lines to the left of zero. When set, rotate the locking knob clockwise until snug to lock the number dial in place.

#9 set the little dial below the downfeed to .0001" or .0002" this is the incremental downfeed amount. Then set the number on the operator panel to the amount per pass to multiply the little downfeed by. Example, if you set it to 02 and have the little dial set at .0001" it will downfeed two increments of .0001" or .0002" total per pass. If the little dial is set to .0002" the it would move two increments of .0002" per pass, or .0004" total each pass.
