To turn on the tool press the switch on the “ON” side. To
stop the tool, press the switch on the “OFF” side.
Turning On
• Use moderate and constant pressure on the work piece. Use uniform movements to get a soft grind. If you use excessive
pressure the motor will overheat and the grinding wheel will wear out faster.
• Locate the bevel angle in the piece to hone and try to keep its shape.
• The disc shall turn against the object to be honed.
• Keep a tray with water handy to immerse regularly there the work piece to prevent overheating. Otherwise, the metal
may weaken.
Operation
In most cases, the tool’s blade angle shall be 20° with
regards to the grinding wheel.
Scissors:
When possible, unscrew the scissors to make the
honing job easy and safe. Hone only the outside and work
from the blade’s heel to the tip.
Knives:
Most knives can be honed in both faces. Work
from the blade’s heel to the tip.
Screwdrivers:
A perfectly honed screwdriver need to be a
perfect rectangle, totally flat and perpendicular to the
screwdriver blade. Both sides and faces shall be flat and
perpendicular to each other. To hone a damaged
screwdriver, keep each face of the screwdriver against the
grinding wheel. Then place the tip against the wheel to get
it leveled.
Bits:
Bits get honed better using a honing template that
can be purchased in most hardware stores. Use care not to
damage it with the grinding wheel. Start in one side of the
tip in the existing angle. Then, twist the bit keeping a
constant angle with the grinding surface. Hone the tip only.
This technique requires a lot of practice. Make some test
with the grinder off. Assure to keep the tip original angle to
get an efficient bit. Refer to the illustration to see the angles
(
D
). To hone most of the bits, the tool rest in the right of
the machine is built with a slot to position the bit with the
right angle (

).
Lawn Mower Blades:
These are only honed in one side
and the other side only toned a little bit. Double check the
blade is balanced when honed. Otherwise it can cause
severe damage to the lawn mower crank. There are very
economical scales that can help in learning if the blades
are well balanced. To prevent to accidentally start up the
lawnmower always remove the spark plug cables before
servicing.
