Adjust the
RELIEF FIXED FINGER
so there is a small
gap between the
FIXED FINGER
and the wheel (about
1/32" 1/16" [1-1.5 mm].
OPERATION
STEP 4: RELIEF GRIND
PRESS THE RELIEF GRIND
ICON TO CONTINUE.
Pull the left side
PLUNGER PIN and rotate the FINGER AND BODY ASSEMBLY
up (counter clockwise
looking from the right side) to the
RELIEF
position until the left side
PLUNGER PIN
locks into position.
NOTE: The plunger pin must be fully engaged with the RELIEF ADJUSTER
KNOB for proper function.
Replace the 1" wide [ 25mm] grinding wheel with a 3/8" [10 mm] wide relief wheel for relief grinding.
As the reel diameter gets smaller and the number of blades increases, a smaller diameter wheel tends to
work better. A 3.5"
D
ia. [89 mm] x 3/8" [10 mm] wide wheel is furnished with the grinder for these smaller
reels. As a general rule, use the largest grinding wheel practical to relief grind. (A larger 5"
D
ia. [127 mm] x
3/8" [10 mm] wide is also furnished with the grinder and should be used on the larger reels).
THE HIGH POINT OF THE RELIEF FINGER SHOULD ALWAYS BE AT THE CORNER OF THE GRINDING
WHEEL THAT IS MAKING CONTACT WITH THE REEL. ON THIS GRINDER, THAT IS ALWAYS THE RIGHT
HAND SIDE OF THE GRINDING WHEEL. SEE FIG. 64.
REEL SPIRAL
Check to see if your mowing unit is a normal or reverse helix.
NORMAL REEL HELIX.
If the wheel has a taper, place the high side of the wheel to the
left side for a normal helix reel. Most mowing units are normal
helix. This will allow the wheel to grind to the end of the blade.
REVERSE REEL HELIX.
If the wheel has a taper, place the high side of the wheel to the
right side for a reverse helix reel.
If you do not use a pre-shaped wheel so the right side contacts
the blade, the last 3/8" [10mm] of the blade may not be ground.
