Maintenance; Troubleshooting; Technical Data - Urrea EB906 Manual De Usuario

The grinding wheel should rotate "into" the
object being sharpened.
NOTE: Excessive pressure may damage the tool,
cause the motor to overheat, and prematurely
wear down the grinding wheel.
The following recommendations will help
you sharpen specific tools:
TWIST DRILL BITS
Drill bits are best sharpened on a sharpening
jig (available at most hardware stores). Begin
on one side of the point at the existing angle,
then twist the bit while maintaining contact
with the grinding surface. Sharpen only the tip.
This technique requires considerable practice,
so take your time and make a few "dry runs"
first with the grinder off. Be sure to maintain
the original cutting edge angle as this is impor-
tant to the efficiency of your bits. One work
rest has a V-groove angled to fit most drill bits.
LAWN MOWER BLADES
Lawn mower blades are usually sharpened on
only one edge and dressed up slightly on the
other. Perform this sharpening process on both
cutting ends of the blade. After sharpening, be
sure to balance the blade by removing addi-
tional material.
CAUTION: An unbalanced lawn mower
blade may cause excessive vibration which will
damage the lawn mower.
CHISELS AND SCREWDRIVER BLADES
When sharpening chisels and screwdrivers,
work rest should support the chisel at the cor-
rect angle against the wheel.
WHEEL REPLACEMENT
If you must replace a grinding wheel, be sure
to obtain one with a safe rated speed greater
than the "no load speed" rpm marked on the
data plate of the grinder. To replace the grind-
ing wheel, remove the wheel cover by loos-
ening the screws. Loosen the wheel nut in a
clockwise direction for the left side and a coun-
terclockwise direction for the right side.
Remove the outer flange and grinding wheel.
To install a new grinding wheel, reverse the
above procedure. Be sure the grinding wheel
and outer flange are properly seated on the
spindle shaft.

MAINTENANCE

WARNING: When servicing, use only identical
replacement parts. Use of any other part may
create a hazard or cause product damage.
GENERAL
Keep the bench grinder clean. Remove dust
from working parts and beneath the grinder
frequently. Make sure the bench grinder oper-
ates properly. Check screws, nuts, and bolts for
tightness.
Servicing requires extreme care and knowledge
and should be performed only by a qualified
service technician. For service we suggest you
return the tool to your nearest AUTHORIZED
SERVICE CENTER for repair. When servicing, use
only identical replacement parts.
