BASIC OPERATION
Tobeefficientandworkasdesigned,yourtoolsshouldbe
keptsharp.Dulltoolscanandwillcauseaccidents.
Bench grinders are ideal for sharpening tools such as
chisels,scissors,etc.,andforremovingrustorcorrosion.
Grindersremovematerialrapidlysopressureisthekeyto
efficientgrinding.
Theproperwaytosharpenatoolandavoidoverheatingis:
Keeptheobjectinconstantmotion,movingitataneven
pace.
Neverforceatoolagainstthegrindingwheel.
Keepthetoolcoolbyusingapanofwater.
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.
ON/OFF SWITCH
See Figure 10, page 12.
Thebenchgrinderfeaturesafrontaccesson/offswitchfor
convenienceandsafety.
SHARPENING TWIST DRILL BITS
See Figure 11, page 13.
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importanttotheefficiencyofyourbits.
SHARPENING LAWN MOWER BLADES
See Figure 12, page 13.
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additionalmaterial.
NOTICE:
Anunbalancedlawnmowerblademaycauseexcessive
vibrationwhichwilldamagethelawnmower.
SHARPENING CHISELS AND SCREWDRIVER
BLADES
See Figure 13, page 13.
Whensharpeningchiselsandscrewdrivers,workrestshould
supportthechiselatthecorrectangleagainstthewheel.
