7.Starting at the end of a reel blade, carefully move the wheel head in toward the blade. Take extreme care that the blade you are grinding is placed firmly on the finger guide slope. At this point, do not let the grinding stone make contact with the blade. Check for clearance between the “next blade” and the grinding wheel. Figure
8.Start the wheel head.
9.Start eh coolant pump at full flow.
10.Adjust the wheel head “in” to achieve the desired grind.
WARNING
INITAILLY, UNTIL THE OPERATOR IS VERY USED TO THIS OPERATION, WE RECOM- MEND THAT HE GRINDING CARRIAGE BE MOVED BY HAND TO INSURE BETTER CON- TROL.
11.Pull the carriage along gently when starting the relief grinds. Remember to have the coolant at full flow.
CAUTION 
WHEN MANUALLY TURNING THE REEL, BE SURE TO KEEP HANDS CLEAR OF PINCH POINTS BETWEEN THE REEL AND STONE.
12.Make sure the grinding wheel clears the end of one blade before indexing to the next. There are two (2) methods of relief grinding:
a.Manually move the carriage to one end and return on the same blade before in- dexing to the next blade.
b.As the carriage reaches the end of one blade, the grinding wheel is moved clear of the blade, the reel is indexed to the next blade, and this blade if ground as the carriage returns.
Continue this operation until every blade is completely ground to the original equipment manufacturer’s speci- fications. The thickness and hardness of the blades being sharpened determines how much material can be ground in one pass. With experience, the operator will get a feel for different blades.
13.The angle of relief is adjustable using the thumb bolt. Turn the thumb bolt clockwise for less angle and

NOTE
The lower the position of the finger guide, the greater the relief angle imparted to each blade. Conversely, the lower the center of the grinding wheel, the greater the relief angle. If the blade is positioned from the center of the grinding wheel (or above), no relief will be ground on the blade.
The guard (A) the finger guide is mounted to may be rotated to gain more grinding angles. Simply loosen the Allen screw (B) and move guard to the desired location and
