Grinder Safety Warnings
POSITION OF GRINDER
1. To avoid the possibility of the tool
plug or receptacle getting wet,
position grinder to one side of a wall
mounted receptacle to prevent water
from dripping onto the receptacle or
plug. The user should arrange a “drip
loop” in the cord connecting the saw
to a receptacle. The “drip loop” is
that part of the cord below the level
of the receptacle, or the connector if
an extension cord is used, to prevent
water traveling along the cord and
coming in contact with the receptacle.
If the plug or receptacle does get wet,2.
DON’T unplug the cord. Disconnect
the fuse or circuit breaker that
supplies power to the tool. Then
unplug and examine for presence of
water in the receptacle.
EXTENSION CORDS
Use only extension cords that are3.
intended for outdoor use. These
extension cords are identied by a
marking “Acceptable for use with
outdoor tools; store indoors while not
in use.” Use only extension cords

General Operating Instructions
Turning the Grinder on and off
Check that the Power Switch (42) is1.
off and that no objects are in contact
with, or near, the wheels.
Fill the Water Reservoir (22) with2.
enough clean water so that up to 3/4”
of the side of the wheel is wet when
the wheel is rotated (approx. 6 to 8
oz.).
With dry hands, plug the unit into a3.
GFCI outlet.
Turn the Power Switch on.4.
When nished using the Grinder, turn 5.
the Power Switch off and unplug the
unit.
Emptying the Water Reservoir
To empty the Water Reservoir (22) of
water:
Slide a shallow bowl which can holda.
at least 8 oz. of water, under the
Water Reservoir and twist and pull
off the Plug (25) at the bottom of the
Reservoir.
When all the water is drained outb.
of the Reservoir, slide the bowl out
from under the unit and replace the
Plug.
Discard the water in a safe location.c.
Do not pour the water down a drain
as it may contain particles which can
clog plumbing.
Dressing the Wheel
Dressing is the process of removing
built-up, dull particles from the
surface of the wheel, exposing the
original sharp abrasive particles, thus
restoring the surface of the wheel.
Dressing is an important process
in preparing a new wheel before
rst use because the surface may
have stray particles from the factory
which will affect the surface. It is
also important as a maintenance
procedure to clean off build-up on
the wheel during use. You will need
a grinding wheel dresser (sold
separately) for this operation.
Note: Stand to the side of the wheel and
wear a face shield to protect against
ying sparks.
If the wheel is new, let it run for a full6.
minute with no load.
If you are using a “pistol grip” dresser,7.
grip the handle rmly with one hand,
and the arm of the dresser with the
other. Allow the wheel to reach full
speed. Use the tool rest to support
your hand and the dresser, and apply
to the wheel evenly to all surfaces.
If you are using an “in-line” dresser,8.
hold the handle rmly, put the dresser
on the tool rest so that its wheels can
move freely (the exposed parts of
the wheel should be facing up). Let
the wheel reach full speed and apply
the dresser evenly to all surfaces
used for grinding. There is no tool
rest on the wet wheel, but the lower
speed still allows for easy, free-hand
dressing.

Page 11For technical questions, please call 1-800-444-3353.SKU 35098
Using the Grinder
Always bring the workpiece into the1.
Wheel gently and without jarring.
When using the Wet Grinding Wheel,2.
periodically check that the wheel is
wet on the sides up to about 3/4”.
As needed, rell the Reservoir with
more clean water. Be sure to turn the
power off and unplug the unit before
lling with more water.
When using the Dry Grinding Wheel,3.
the workpiece will quickly become
heated, therefore frequent quenching
is required. Wipe off excess water
before addressing the tool to the
Grinder.
Note: When grinding wood cutting tools,
or any metal tool, do not let the
metal become heated so much that it
gets blue-colored, or it will loose it’s
temper and be too soft to be useful.
As soon as the tool begins to show
an orange glow, stop grinding and
quench the tool with water.
If the tool does get hot enough to
become blue-colored, the overheated
portion of the metal must be ground
off, and the tool must then be re-
sharpened.
Due to frequent misuse and overuse,4.
screwdrivers commonly need to be
ground. The simple procedure is
to grind them at, however hollow
grinding will give a better result. To
hollow grind, simple apply the at of
the screwdriver to the wheel in such
a way that a very slight curvature
results. After grinding the at of the
blade, the tip must be ground at and
even.
Flat chisels should be ground in5.
the same way as above, with the
exception to attening the tip. The
tip should be ground to a mild point
depending upon the desires of the
user. The most common example is
60°.
Center punches should also be6.
hollow ground, but you must rotate
them evenly in a circle in order to
achieve the desired result. The tool
must have the tips ground to a point.
Common points are 90° for a center
point and 60° for a prick punch.
To prevent accidents, turn off the tool7.
and disconnect its power supply after
use. Clean, remove water from the
Water Reservoir, then store the tool
indoors out of children’s reach.
