OPERATING INSTRUCTIONS
K.Turn the Torque Potentiometer to zero. Turn on the Spin motor.
NOTE: The spin drive will apply torque load against the fingers.
Slowly turn the Relief Torque Potentiometer up to approximately 15.
NOTE: Free turning reels may need a lower value than 15. Stiff
reels or reels with a drive train may need a higher torque than 15.
Do not exceed 45 on the relief torque potentiometer setting.
L. Move the wheel all the way to the left proximity switch watching
for proper clearance between the grinding wheel and the blade.
When the grinding head reaches the left proximity switch, the index
finger should spring forward. See FIG. 75. The grinding wheel should
come off the reel blade, but the blade should remain on the fixed
relief finger. See FIG. 74. If not, adjust the left side proximity switch
position until correct. Check for proper clearance between
the index finger and the front side of the blade on the return trip
to the home (right hand proximity switch) position. See FIG. 76.
Also verify clearance between the index finger and the reel blade
support spiders.
M.Stop the traverse in home position and check for a proper blade
index. See FIG. 77. The fixed relief finger should
come off the reel
blade, the relief torque from the spin drive should rotate the reel so
the next blade contacts the moveable indexing finger and pushes
the indexing finger back against its stop.
The traverse drive control is factory set with a two second dwell
time before it reverses the carriage travel. This is to allow time for the
reel to rotate and the index finger to catch the next blade. If
necessary the dwell time can be adjusted (refer to Control Board
Potentiometer Adjustments section in the Assembly and Service
manual).
N.Allow the grinder to traverse down and back to verify everything
is properly set up. Turn the traverse potentiometer to zero once the
home position is reached.
O. Turn on the Grinding Wheel Motor.
P.Turn the traverse speed potentiometer to approximately 15 fpm.
Slowly infeed the grinding wheel until you are able to grind the full
length of the reel blade evenly. You can infeed between .005" to
.012" at a time. Be sure you have ground all the blades before
infeeding further.
NOTE: Traverse speed should be approximately 15 fpm. If you are
removing a small amount of stock on initial infeeds, faster traverse
speeds are suggested. If you are removing a large amount of stock on
later infeeds, slower traverse speed may be required.
WHEN YOU HAVE SUCCESSFULLY COMPLETED THE SPIN GRIND AND
RELIEF GRIND ON A GIVEN MOWING UNIT TYPE, THEN MEASURE AND
COMPLETE THE SETUP CHART ON LAST PAGE OF THIS MANUAL.
