OPERATING INSTRUCTIONS
REEL SPIRAL OR HELIX
RELIEF GRINDING TO COMPLETE THE REEL
GRINDING PROCESS
1. This grinder is equipped with two grinding wheels
and two grinding wheel guards. Prior to relief
grinding install or verify installation of the 3/8"
(9.5 MM) wide grinding wheel and the relief
wheel guard which has the relief and index fingers
attached. See FIG. 71.
2. Check to see if your mowing unit is normal or
reverse helix. When standing behind the mowing
unit when the mowing unit is sitting in the normal
position on the ground, iIf the spiral is such that
the right side of the blade cuts before the left, it is
a right hand lead in or a right hand spiral reel. If
the spiral is such that the left side of the blade cuts
before the right it is a left hand lead in or left spiral
reel. Most reels made today are right hand and
are referred to as normal helix.
NOTE: AS YOU LOOK INTO THE GUIDE FINGER
ON PAGE 42, IT SHOWS THE NORMAL REEL
HELIX. THE HIGH POINT OF THE RELIEF FINGER
IS ON THE RIGHT HAND SIDE OF THE GRINDING
WHEEL. As you look into the guide finger on PAGE
43, IT SHOWS THE REVERSE REEL HELIX. The high
point of the relief finger is on the right hand side of
the grinding wheel.
3. Reset the Traverse Limit Proximity Switch so the
grinding wheel clears the reel at both ends by
approximately 1/16" (1.5 mm) or the reel blade
comes off the fixed relief finger on the right side.
See FIG. 71 -77.
4. Set Grind Selector to variable torque relief. Set
Spin Drive Rotation switch to rotate the reel into
the stop finger, counterclockwise (CCW) when
looking at the right side.
NOTE: RELIEF TORQUE REEL ROTATION IS
ALWAYS OPPOSITE SPIN ROTATION.
NOTE: THE SPIN DRIVE ROTATION SWITCH
MUST BE IN THE OFF POSITION WHEN
CHANGING GRIND SELECTOR SWITCH.
