HOW TO CHOOSE THE CORRECT GRINDING WHEEL FOR THE BLADE
The 1” wide grinding wheel or 2” wide abrasive belt 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.
This 1/2” wide grinding wheel is required to sharpen curved/wavy cutting edge mulching blade. The arbor spacer (8000-27)
is necessary to mount a 1/2” wide grinding wheel.

IMPORTANT STAND NOTE:
The MAG-8200 Series mounts in the
same orientation as the MAG-8000. So
when you follow your MAG-10400 Stand
instructions “STEP 7”.
The yellow base of the MAG-8200 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-8200 series.
IMPORTANT DUST COLLECTOR
NOTE:
The MAG-8200 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-8200 we have moved up to
a 4” diameter grit guard inlet and 4” di-
ameter 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 or
MAG-8200 directly to the stand table top.
For mounting water-cooled units, follow the
water-cooled mounting instructions.

Installing the tank
1. When building the stand bolt the tank shelf on the bottom set of (3) holes on the column below the
sharpener.
2. Set tank on shelf, use (4) 5/16 bolts and washers to secure tank to shelf.
Preparing the Tank
1. Take the cap o󰀨 the tank (this can be used for storage to keep coolant from evaporating during
o󰀨-season)
2. Remove lter sock, and packaging from inside the tank.
3. Double check the hose is still connected to the pump and didn’t slip o󰀨 during shipping.
Connecting to sharpener
1. The clear vinyl tubing from the tank connects to the hose barb behind the sharpeners electric motor,
secure with loop connector.
2. The power cord for the pump plugs into the outlet on the electric panel of the sharpener. This outlet is
switched by the blue switch.
3. There is a red valve on the front of the sharpener to regulate how much coolant is delivered to the
wheel.
4. Always turn o󰀨 the grinding wheel when adjusting coolant nozzle.
5. Make sure to adjust the nozzle of the coolant before running the grinding wheel. It may have shifted
during shipment. Adjust the coolant nozzle to deliver coolant to the
grinding wheel.
Preparing the Coolant
1. Double check the vinyl hose is connected to the pump.
2. Measure a 1/2 gallon of coolant, and pour into tank.
3. Fill tank with 5 gallons of tap water.
4. Put the lter sock into the tank, the metal ring will stop it from falling in.
5. Push the yellow spiral hose into the lter sock, a few yellow ribs should
be inside the neck of the tank.
6. Slip the top of the yellow spiral hose onto the water tray metal inlet.
7. Turn pump on, open valve slightly to test coolant system, check for
leaks.
1. REMOVE lter sock from tank
2. REMOVE 30” vinyl clear tubing from tank
3. REMOVE foam packaging from tank
4. CHECK to see if pump pre-lter and clear vinyl tube are still connected to pump. These are both slip
on connections, but can sometimes come apart during shipping.

Tips & Questions about the Coolant
What is the best way to test the newly assembled water-cooling system?
Fill the tank with just 2 gallons of water - then run the pump and check for leaks before you add coolant.
Do I need that much liquid in the tank?
If you are not a heavy user, you can ll your tank with 3 gallons of water then slowly add a little coolant
and then check with the refractometer to hit 3 BRIX.
The amount of liquid in the tank is your cooling “battery” as you sharpen the liquid will get warmer from
taking away the heat from the blades you are sharpening. If you are not sharpening constantly for hours
you can use less total liquid in your tank, and therefore use less coolant if you like.
Why is the BRIX concentration value important?
If you drop below 1 BRIX you will loose the rust prevention benet of the coolant, this will result in all the
metal you are cutting from the blades to rust. The sharpener will have rust metal shavings all over it, and
the coolant will turn orange. This may lead to early pump failure and seizing of other moving parts.
How to Measure Concentration of your Coolant
1. See instructions in the refractometer case for calibration of the
refractometer.
2. Cycle the pump and let the coolant circulate through the system and cycle for 30 seconds
3. Use the pipette to draw some coolant from the orange nozzle.
4. Open the slide cover of the refractometer and put one drop of
coolant on the blue surface.
5. Close the slide cover.
6. Look through the eye glass of the refractometer.
7. You can use the focus ring of the refractometer to see the scale more clearly.
8. Read the BRIX side of the scale.
9. The desired concentration is 3.3 BRIX (+/- 0.2 BRIX)
Balancing Coolant Concentration
If less than 3.3 BRIX add coolant (TRIM C270CG uid)
If greater than 3.3 BRIX add water
Repeat above steps to test until you are within range.

30 DEGREE ANGLE
MOST BASIC ANGLE - READ FOLLOWING INFO!
30 degrees 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.
FIXED WORKTABLE
Turn the machine off. Lower the grinding wheel with the crank handle on the top of the MAG-8200,
lower the wheel as close as possible to the plastic surface without touching it (approx 1/32”), so you can
see a small gap. The thickness of a business card is a good gage as well.
MODULAR WORKTABLE
Turn the machine off. Lower the grinding wheel with the crank handle on the top of the MAG-8200,
lower the wheel as close as possible to the rounded worktable without touching it (approx 1/32”), so you
can see a small gap. The thickness of a business card is a good gage as well.
If you do this adjustment with the machine on you risk grinding into your worktables. This will alter the
angle that the sharpener will grind on the blade. If you accidentally grind into either table, turn the insert
around so you have a fresh surface again. Or visit magna-matic.com and purchase new worktables.
ANGLE ADJUSTMENT
WARNING WHEN USING ELECTRIC TOOLS, BASIC SAFETY PRECAU-
TIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE
THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL
INJURY.
CAUTION TURN OFF
AND UNPLUG
BEFORE SERVICING!
The grinding wheel must ALWAYS
be lowered to the worktable
for ALL ANGLES.
Adjust wheel downward to
adjust for wear or to change
angles.

CHANGING TABLE INSERTS
IMPORTANT: You will only need about a 1/4 turn to loosen or tighten.
1. Use the supplied 3/16” hex T-handle wrench to loosen the vise.
2. Remove the current table seated in the framework.
3. Notice how the steel insert plate ts into the framework of the two aluminum arms of the modular
worktable.
4. Place the table into the framework.
5. Push the table towards the grinding wheel so you are squarely seated in the stops in the framework
(see red highlighted area)

How to Set the four possible angle settings.
• 30° bring table to top setting, level with first half-circle.
• 35° lower table to second half-circle
• 40° lower table to third half-circle
• 45° push table so it bottoms out as low as it will go.
• Lastly lower the grinding wheel via the crank handle on top
of the sharpener. Leave approx. 1/32” of space between the
wheel and table. Do not grind into the table.
CHANGING ANGLES
IMPORTANT: You will only need about a 1/4 turn to loosen or tighten.
The modular worktable system can be set to 4 angle settings.
30 / 35 / 40 / 45 degree cutting edge angles
As an example these instructions will set the sharpener for 35 degrees:
1. Use the T-handle wrench to loosen the angle adjustment bolt, but leave light tension on the bolt, so
the arms stay in-place but still move.
2. Insert the T-handle wrench into the (second from the top) half-circle shape, this provides a stop.
3. Push down on the worktable arms until they hit the t-handle.
4. Pull the T-handle out and tighten the adjustment bolt.
5. Lower the grinding wheel via the crank handle on top of the sharpener.
6. Bring the wheel down within approx. 1/32” of the table.
7. The sharpener is ready to grind 35 degrees.
