WARNING
CAUTION
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.
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.
4.
It is best to use the 1" inch wide grinding wheel to sharpen a conventional
blade. Mount the 1" wide grinding wheel on the MAG-8000. (see page 7)
(note the 1/2" wide wheel can be used on conventional blades, but the 1" is
more cost effective)
5.
Place the flat worktable insert into the worktable vice. Position it at the
desired angle according to page 10-11. Tighten the vice bolt with the
spanner wrench.
6.
Review pages 10 and 11 to adjust the MAG-8000 to the desired angle.
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.
3.
Keep firm downward pressure on the top of the blade so that
contact is maintained with the worktable. This is important because the
blade edge-angle is referenced off the worktable.
4.
The force into the grinding wheel should be substantial resulting in a
continuous stream of sparks and a deep smooth grinding sound.
5.
The grinding process should be continuous without interruption until finished.
