17. USE RECOMMENDED ACCESSORIES. Consult the owner's manual for
recommendedaccessories. The useof improper accessories may cause risk
of injury to persons.
18. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or
if the cutting tool is accidentally contacted.
19. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other
part that is damaged should be carefully checked to determine that
it will
operate properly and perform its intended function
- check for alignment
of movingparts, bindingof movingparts, breakage of parts, mounting, and
any other conditions that mayaffect itsoperation. A guard or other part that
is damaged should be properly repaired or replaced.
20. DIRECTIONOF FEED. Feedwork intoa blade or cutter against the direction
of rotation of the blade or cutter only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don't
leave tool
until it comes to a complete stop.
22. PROPER GROUNDING. This toolshould be groundedwhile inuse toprotect
the operator from electric shock.
23. EXTENSIONCORDS: Use only three-wire extension cords which have three-
prong grounding-type plugs and three-pole receptacles which accept the
tool's plug. Replace or repair damaged or worn cord immediately.
VOLTAGE WARNING: Before connectingthe tooltoa power source (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplateof the tool. A power source withvoltage greater than that specified
for the tool can result in SERIOUS INJURY to the user
- as well as damage to
the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with
voltage less than the nameplate rating is harmful to the motor.

GROUNDING INSTRUCTIONS
ALL GROUNDED, CORD-CONNECTEDTOOLS:
In the event of a malfunctionor
breakdown, grounding provides a pathof least resistance for electric currentto
reducethe risk of electric shock. This toolisequippedwithanelectric cord hav-
ing anequipment-groundingconductor and a grounding plug. The plugmust be
pluggedintoa matchingoutlet that isproperly installed andgroundedinaccord-
ance
with all local codes and ordinances.
Donotmodifythe
plug provided - if it willnot fit theoutlet, havetheproper out-
let installed
by a qualified electrician.
Improperconnectionof the equipment-groundingconductor can result
in a risk
of electric shock. The conductor with insulationhaving anouter surface that is
green with or without yellow stripes is the equipment-grounding conductor.
If
repair or replacement of the electric cord or plug is necessary, do not connect
the equipment-grounding conductor to a live terminal.
Check
with a qualified electrician or serviceman if the groundinginstructionsare
not completely understood, or
if in doubt as to whether the tool is properly
grounded.
This tool is intended for use on a circuit that has an outlet that looks like the
one illustrated
in Figure A. Thetoolhas a groundingplugthat looks like the plug
illustrated
in Figure A. A temporary adapter, which looks like the adapter illus-
tratedinFigure B andC, may be usedtoconnectthisplugtoa 2-pole receptacle
as showninFigureB
if a properly grounded outletis notavailable.The temporary
adapter shouldbe usedonly
until a properly groundedoutlet canbeinstalled by
a qualified electrician. The green-colored rigid ear, lug, etc. extending fromthe
adapter mustbe connectedtoa permanentground suchas a properly grounded
outlet box.

1 mm
(approx.
1/3") below the surface of the
grinding wheel. Adjust height by turning
the guard clockwiseto lower
it, or counter-
clockwiseto raise
it.
Wiping off the antirust
Wipe off the antirust on the sharpening platform guide (rail) and the sharpeningholder.

The nut for raising or loweringthe poleon
either side raises the pole
0.5 mm (1/32")
for each graduation, when turned clock-
wise, and
it lowers the pole, conversely,
0.5 mm (1/32") when turned counterclock-
wise.
Tilt the sharpening platform guide slightly
with right side downward
so that the blade
contacts the right side surface of thegrind-
ingwheel.
Adjusting sharpening holder
The sharpening holder horizontal(forward)
adjust screws should be unscrewedto allow

Adjusting coolant flow
Putwater inthe coolant reservoir.
Turn the knob
so that the marking is posi-
tioned vertically to make the coolantflow.
Turn the marking to the horizontal posi-
tion tostopthe coolantflow.
NOTE
:
Adjust the coolant flow adequately. If the
debris from the grinding wheel and the
blade
is washed away by the coolant, the
coolantflow
is excessive.
Draining used coolant
The used coolant drains out through the
drain hose (vinyl tube) provided. Have a
pan or drain system ready to catch it.
