ASSEMBLY
IMPORTANT - There is a transport bolt that must be removed
before use! The bolt goes through the two uprights and the pivot plate. If this
bolt is not removed it will be impossible to adjust the grinding wheel. First
remove the grit guard, loosen the 5/16” bolt, and replace it with the plastic knob.
Then pull the grit guard outward and set it aside.
MOUNTING THE 1/2”
WIDE WHEEL, for
sharpening mulching
blades.
The 1/2” wide grinding
wheel requires the arbor
spacer.
The 1/2” wide wheel
will be in-line with the
rounded mulching blade
worktable insert. Be sure
the arbor spacer
(8000-27) is used as
shown in the image.
Use (2) 1/2” wrenches to remove the
transport bolt. Connect the crank handle
to the adjustment rod. Align the set
screw in the crank handle to the at on
the adjustment rod and tighten the set
screw (1/8” allen). You may need to
make a half-rotation on the crank handle
to loosen the pressure on the transport
bolt to remove it.

ASSEMBLY
TESTING THE MAG-8000
Before turning the unit on, test the unit by checking if the grinding wheel moves freely.
Ensure the MAG-8000 ON/OFF switch is in the OFF POSITION, plug the MAG-8000 into
a 20 amp, 110 volt outlet. Switch the ON/OFF switch to the ON POSITION to test the
motor. The motor should achieve FULL speed in 1-2 seconds. If it does not,
(see page 19) or contact MAGNA-MATIC (800-328-1110).
Steps to connect the grit guard to the MAG-8000.
1. The yellow ACTIVE GUARD must be on the inside of the black steel
guard by the motor.
2. The top lip of the grit guard must be on top of the yellow body plate of
the MAG-8000.
3. Slide the grit guard assembly into the MAG-8000 and the
interlocking tabs and lips will engage keeping the guards solid.
4. Screw the plastic knob into the threaded hole to hold the grit guard
assembly in place.
5. See top image on page 6, for a view on attaching the grit guard.
MOUNTING THE 1”
WIDE WHEEL, for
sharpening
straight-edged blades.
DO NOT USE the arbor
spacer when using the 1”
wide grinding wheel. Only
use the arbor nut.

ANGLE ADJUSTMENT
IMPORTANT - ALWAYS turn the MAG-8000 OFF when
changing or adjusting worktable inserts.
New [gen6] worktables (blade rest)
The new change to the MAG-8000 [gen6] is the implementation of worktable inserts. This new design
allows for future inserts for specic blades, and dierent size worktables. Additionally the worktable
insert provides the ability to dial in angles from 25º to 45º.
The worktable inserts slide into a fixed vice that is clamped by tightening a 5/16” bolt with the hex end
of the supplied spanner wrench or a 1/2” wrench.
The black flat worktable insert is for straight flat. (conventional blades)
The steel rounded worktable insert is for curved cutting edge. (mulching blades)
ABOVE: Worktable
position decal
RIGHT: Angle information
decal
Angle Indicators
These two decals are located on the
MAG-8000 they indicate worktable
positions required to achieve the listed
cutting edge angles.
30 degrees is the ONLY angle where the
worktable remains in one position over
the life of a grinding wheel. All other
angles require that the worktable be
moved to a position corresponding with
the chart on the MAG-8000. Use the
chart on the MAG-8000 (shown to the
right) to move the worktable insert when
the grinding wheel is at a diameter listed.
Note: the black
plastic wear plate is
reversible.

Worktable Set-up
The base of the worktable inserts are slotted.
Slide the worktable insert into the vice (shown below)
Once in place at the desired angle position, tighten the bolt in the worktable vice.
DO NOT OVER-TIGHTEN (only a 1/4 to 1/2 turn is required to clamp the insert.)
The spanner wrench has a 12 point hex wrench used for the bolt to tighten the insert in place.
A 1/2” wrench or socket can also be used.
Worktable Alignment
(Shown below) Align the front of the
insert to the line of the letter of the angle
position you desire. In the image the
insert is aligned to the letter B, which is a
45º @ 6” diameter grinding wheel. The
red arrow shows the front of the insert,
which is the part to align.
Left: View of the
spanner wrench used
to tighten the vice to
hold worktable inserts.

30 DEGREE ANGLE
MOST BASIC ANGLE - READ FOLLOWING INFO!
30 degrees is the most consistent and easiest angle to maintain in the
MAG-8000. It is also 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.
Align the worktable insert (at or rounded) to the 30º arrowed mark on the
worktable vice (see yellow decal in image below). This will make the insert
square to the vice (flush on back and front). Tighten it in place with the hex end of
the spanner wrench.
Lower the grinding wheel with the black crank handle on the top of the
MAG-8000, lower it as close as possible to the worktable without touching the
worktable (approx 1/32”), so you can just see a small space.
The worktable insert DOES NOT need to be moved to compensate for grinding
wheel diameter as other angles do. Simply keep lowering the grinding wheel
within a 1/32” from the worktable. See the red arrow, showing the approx. 1/32”
distance from the worktable to the wheel. Maintain this closeness to the
worktable to maintain the desired angle.
