The MAG-8100 Sharpener is only designed for straight at cutting edges.
The 1” wide grinding wheel is used for conventional lawn mower blades with straight at cutting edges. When you mount the
1” wheel use only the arbor nut. Do not use the arbor spacer with the 1” wide wheel. If you need a sharpener to do curved /
wavy cutting edges you need the MAG-8200M model sharpener.

IMPORTANT STAND NOTE:
The MAG-8100 Series mounts in the same
oriention as the MAG-8000. So when you
follow your MAG-10400 Stand instructions
“STEP 7”.
The black base of the MAG-8100 is not
threaded so the mounting to the stand is
with a through bolt 1/4”.
The 10400-04 balancer arm base is a little
longer now for the new
MAG-8100 series.
IMPORTANT DUST COLLECTOR
NOTE:
The MAG-8100 Series mounts needs the
MAG-200 Dust Collector
mounted under the grit guard.
It is mounted on the opposite side that it
was for the MAG-8000.
For the MAG-8100 we have increased to a
4” diameter grit guard inlet and 4” diameter
yellow spiral hose. This increases the air
ow up 400 CFM from 250 CFM.
The table top orientation for the MAG-10400
stand for all MAG-8000, MAG-8100, and MAG-
8200 Sharpeners. This is covered in Step 7 of the
stand instruction sheet.
Use two 1/4-20 x 2” long hex bolts with 1/4 nuts
to directly mount the MAG-8100 directly to the
stand table top.

30 DEGREE ANGLE
MOST BASIC ANGLE - READ FOLLOWING INFO!
30 degrees is the most consistent and easiest angle to maintain in the MAG-8100. It is the industry
average angle on most blades. If you are looking for the most simple way to consistently sharpen your
lawn mower blades, use 30 degrees according to following instructions.
ANGLE ADJUSTMENT
Turn off the sharpener. Lower the grinding wheel by using the aluminum crank handle within a 1/32”
from the worktable. You want to get the grinding wheel as close as possible to the white worktable
As the grinding wheel wears continue to lower the wheel to maintain this closeness to the worktable. By
doing this you will maintain 30 degrees on all your cutting edge angles of your lawn mower blades.
Do not lower the grinding wheel while the sharpener is ON. You risk grinding into the worktable which
will make it more difficult to maintain your blade edge angles.
If you do accidently grind into the worktable the MAG-8100 has an onboard replacement. There are two
of the 8100-39 worktables stacked. If you top one wears out just swap bottom to the top position. Two
worktables must be installed in the MAG-8100 or your blade will not be at the correct height to maintain
30 degrees. If you would like a larger worktable you can purchase two of part 8200-046 to have a 12”
long worktable.

SHARPENING A LAWN MOWER BLADE
Be sure to wear protective clothing while handling and sharpening lawn mower blades. Wear safety
glasses and protective gloves. Always de-burr the underside of the blade, prior to sharpening the blade.
BLADE & SHARPENER PREPARATION
1. Clean the blade to its base material, using the MAG-12008 blade cleaner, or alternate cleaning
process. Inspect the blade for fractures. (never weld mower blades)
2. Check the straightness with the gauge rod of the MAG-1000 blade balancer
(never straighten bent blades)
3. Obtain a balance reading from the MAG-1000 to indicate the light end of the lawn mower blade.
Once the light end is sharpened, that end is complete. The heavy end is used to remove material
for balance. See MAG-1000 instructions for more details on blade balancing.
(never weld mower blades)
4. Adjust the cutting edge angle to 30 degrees.
CONVENTIONAL BLADE SHARPENING
1. Switch the ON/OFF switch to ON position
2. Place the conventional blade on the worktable, you should push and pull the blade across the
grinding wheel. Notice approach the grinding wheel as shown.
3. Stay perpindicular to the rotation of the wheel.
4. Keep firm downward pressure on the top of the blade so that contact is maintained with the
worktable. This is important because the angle is referenced off the worktable and underside of the
blade.
5. The force into the grinding wheel should be substantial resulting in a continuous stream of sparks
and a deep smooth grinding sound.
6. The grinding process should be continuous without interruption until finished.

IT IS TAKING A LOT OF GRINIDNG TO GET A SHARP BLADE?
Are the grinding marks on the “trailing edge” (top edge) of the mower blade cutting edge?
That means your blades were at a steeper angle then you are grinding now. If your blades were
previously sharpened with some other method it is very likely your cutting edge angles are near 45
degrees. It is very common for blades sharpened on other machines or with an angle grinder to be way
up at 45 degrees or steeper. This often happens when people “free-hand” grind.
The MAG-8200 is going to make a consistent 30 degree angle - so your first grinding may take much
longer and use more of the grinding wheel because you are re-machining your blades. This correction
requires a lot of steel be removed to go from 45 down to 30 degrees.
Don’t worry, once fix all your blades and make them 30 degrees, every sharpening after that will be very
fast because you will grind a consistent angle everytime from now on with your MAG-8200.

Keep constant pressure downward to
maintain flat contact with the blade underside and worktable.
Slide the blade back and
forth across the grinding wheel.
Apply pressure into the
grinding wheel to remove
material.

GENERAL CARE:
Keep the MAG-8100 clean, use compressed air to blow the machine o󰀨 periodically.
POLY-V BELT REPLACEMENT & ADJUSTMENT
• Unplug the sharpener from power source.
• Remove the steel pulley cover, 6 screws (5/16” wrench or socket)
• Remove the old belt.
• First put the belt over the grinding wheel pulley.
• Next put the belt on the smooth part of the idler pulley
• Pull the belt over the motor pulley, on to the smooth part.
• By pulling on the belt you will compress the idler pulley.
• Now rotate the pulleys and push the belt over to get all the little ribs of the belt into the groves in the
pulleys.
• Ensure all 6 ribs are seated in all 3 pulleys, and rotate the pulleys by hand to check.
The poly-V belt is always under proper tension by the idler pulley.

Blade Tip Geometry.
What part of a rotary lawn mower blade cuts the grass?
It is a common misconception that lawn mower blades cut like a knife. It actually has more in common
with the way circular saw teeth cut. The confusion comes from the two shapes; a lawn mower blade
looks like a rectangle, and the circular saw is a circle. Keep in mind that when the
lawn mower blade is in motion it is also a circle. The primary di󰀨erence is that a circular saw is for
wood or metal. Because these materials are much more dense, more cutting teeth are required. Turf is
considerably less dense than wood or steel so only two teeth are required.
The tips of the blade do the majority of the cutting work; they are the cutting teeth of the blade.
Repeated observation of worn cutting edges show that the rst 1-2 inches do the majority of the cut-
ting. To produce a cutting tip, three relief angles are necessary.

Understanding the Rotary Lawn Mower Blade
The rst 1-2 inches of any lawn mower blade do the majority of the cutting work and take the most wear. This
is where the most grinding is required to reproduce a cutting tip again.
Often people think that the full cutting edge must be ground back parallel to the rest of the blade. This is not
necessary and can create a dangerous fracture point if done (see image #2). Image #1 shows the over-head
view of the blade that, over the life of the blade will become “tapered looking” from wear and re-sharpening.
This follows the natural wear pattern of a rotary lawn mower blade’s use. We recommend this method be-
cause less steel is removed. Leaving more steel there will help prevent a fracture that could discharge a part
of the blade from the deck.

IMPORTANT NOTES:
Welding, straightening, sharp corners, and
