GENERAL SAFETY
Operating machinery can be dangerous if safety
and common sense are ignored. The user must
be familiar with the operation of the tool. Read
this manual to understand this Wet Sharpener.
DO NOT operate this machine if you do not fully
understand the limitations of this tool. DO NOT
modify this Wet Sharpener in any way.
BEFORE USING THE SHARPENER
To avoid serious injury and damage to the tool,
read and follow all of the Safety and Operating
Instructions before operating the Wet Sharpener.
1. Some dust created by using power tools contains chemicals known to the State of California
to cause cancer, birth defects, or other reproduc-
tive harm.
Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and
other masonry products.
• Arsenic and chromium from
chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work
in a well ventilated area and work with approved
safety equipment, such as those dust masks that
are specially designed to lter out microscopic
particles.
2. READ the entire Owner’s Manual. LEARN
how to use the tool for its intended applications.
3. GROUND ALL TOOLS. If the tool is
supplied with a 3-prong plug, it must be plugged
into a 3-contact electrical receptacle. The 3rd
prong is used to ground the tool and provide
protection against accidental electric shock.
DO NOT remove the 3rd prong. See Grounding
Instructions on page 7.
4. AVOID A DANGEROUS WORKING
ENVIRONMENT. DO NOT use electrical tools in a
damp environment or expose them to rain.
5. DO NOT use electrical tools in the presence of
ammable liquids or gasses.
6. ALWAYS keep the work area clean, well lit,
and organized. DO NOT work in an environment
with oor surfaces that are slippery from debris,
grease, and wax.
7. KEEP VISITORS AND CHILDREN AWAY.
DO NOT permit people to be in the immediate
work area, especially when the electrical tool is
operating.
8. DO NOT FORCE THE TOOL to perform an
operation for which it was not designed. It will do
a safer and higher quality job by only performing
operations for which the tool was intended.
9. WEAR PROPER CLOTHING. DO NOT wear
loose clothing, gloves, neckties, or jewelry. These
items can get caught in the machine during operations and pull the operator into the moving parts.
The user must wear a protective cover on their
hair, if the hair is long, to prevent it from contacting any moving parts.
10. CHILDPROOF THE WORKSHOP AREA by
removing switch keys, unplugging tools from the
electrical receptacles, and using padlocks.
11. ALWAYS UNPLUG THE TOOL FROM THE
ELECTRICAL RECEPTACLE when making
adjustments, changing parts or performing any
maintenance.
12. KEEP PROTECTIVE GUARDS IN PLACE
AND IN WORKING ORDER.
13. AVOID ACCIDENTAL STARTING. Make
sure that the power switch is in the “OFF” position
before plugging in the power cord to the electrical
receptacle.
SAFETY INSTRUCTIONS

14. REMOVE ALL MAINTENANCE TOOLS
from the immediate area prior to turning “ON” the
machine.
15. USE ONLY RECOMMENDED
ACCESSORIES. Use of incorrect or improper
accessories could cause serious injury to the operator and cause damage to the tool. If in doubt,
check the instruction manual that comes with that
particular accessory.
16. NEVER LEAVE A RUNNING TOOL UNAT-
TENDED. Turn the power switch to the “OFF”
position. DO NOT leave the tool until it has come
to a complete stop.
17. DO NOT STAND ON A TOOL. Serious injury
could result if the tool tips over, or you accidentally contact the tool.
18. DO NOT store anything above or near the
tool where anyone might try to stand on the tool
to reach it.
19. MAINTAIN YOUR BALANCE. DO NOT
extend yourself over the tool. Wear oil resistant
rubber soled shoes. Keep oor clear of debris,
grease, and wax.
20. MAINTAIN TOOLS WITH CARE. Always
keep tools clean and in good working order. Keep
all blades and tool bits sharp, dress grinding
wheels and change other abrasive accessories
when worn.
21. EACH AND EVERY TIME, CHECK FOR
DAMAGED PARTS PRIOR TO USING THE
TOOL. Carefully check all guards to see that they
operate properly, are not damaged, and perform
their intended functions. Check for alignment,
binding or breaking of moving parts. A guard or
other part that is damaged should be immediately
repaired or replaced.
22. DO NOT OPERATE TOOL WHILE TIRED,
OR UNDER THE INFLUENCE OF DRUGS,
MEDICATION OR ALCOHOL.
23. SECURE ALL WORK. Use clamps or jigs to
secure the work piece. This is safer than attempting to hold the work piece with your hands.
24. STAY ALERT, WATCH WHAT YOU ARE
DOING, AND USE COMMON SENSE WHEN
OPERATING A POWER TOOL.
A moment of inattention while operating power
tools may result in serious personal injury.
25. ALWAYS WEAR A DUST MASK TO
PREVENT INHALING DANGEROUS DUST OR
AIRBORNE PARTICLES, including wood dust,
crystalline silica dust and asbestos dust.
Direct particles away from face and body.
Always operate tool in well ventilated area and
provide for proper dust removal.
Use dust collection system wherever possible.
Exposure to the dust may cause serious and
permanent respiratory or other injury, including
silicosis (a serious lung disease), cancer, and
death.
Avoid breathing the dust, and avoid prolonged
contact with dust. Allowing dust to get into your
mouth or eyes, or lay on your skin may promote
absorption of harmful material.
Always use properly tting NIOSH/OSHA approved respiratory protection appropriate for the
dust exposure, and wash exposed areas with
soap and water.
26. USE A PROPER EXTENSION CORD IN
GOOD CONDITION. When using an
extension cord, be sure to use one heavy
enough to carry the current your product will
draw.
The table on page 8 shows the correct size to
use depending on cord length and nameplate
amperage rating. If in doubt, use the next
heavier gauge. The smaller the gauge number,
the larger diameter of the extension cord. If in
doubt of the proper size of an extension cord,
use a shorter and thicker cord. An undersized
cord will cause a drop in line voltage resulting in
a loss of power and overheating.
USE ONLY A 3-WIRE EXTENSION CORD
THAT HAS A 3-PRONG GROUNDING PLUG
AND A 3-POLE RECEPTACLE THAT
ACCEPTS THE TOOL’S PLUG.
SEE PAGES 6, 7 AND 15 FOR INFORMATION
ON ELECTRICALS AND WIRING OF THIS

SPECIFIC SAFETY
INSTRUCTIONS FOR THE
WET SHARPENER
Basic precautions should always be followed
when using your wet sharpener. To reduce the
risk of injury, electrical shock, or re, comply with
the safety rules listed below:
1. The operation of any sharpener or power tool
can result in debris being thrown into your eyes,
which can result in severe and permanent eye
damage. ALWAYS WEAR EYE PROTECTION.
Everyday eyeglasses are NOT safety glasses.
ALWAYS wear Safety Goggles (that comply with
ANSI standard Z87.1) when operating power
tools. Using a respirator is also recommended
2. DO NOT operate this machine until it is com-
pletely assembled and installed according to the
instructions. A machine incorrectly assembled
can cause serious injury.
3. FOLLOW ALL WIRING CODES and recom-
mended electrical connections to prevent shock
or electrocution.
4. SECURE THE BENCH GRINDER to a stand
or workbench to prevent sliding or tipping during
start up or use. See page 14.
5. INSPECT WHEELS for cracks or fragments
before starting the machine . REPLACE DAMAGED WHEELS immediately. Parts of the wheel
can be thrown at high speeds causing injury.
6. REPLACE A CRACKED OR DAMAGED
GRINDING WHEEL IMMEDIATELY. A damaged
wheel can discharge debris at a high velocity
towards the operator. Carefully handle the
grinding wheels since they are abrasive. Prior to
replacing a grinding wheel, check it for cracks.
DO NOT remove the blotter or label on both
sides of the grinding wheel. Tighten the spindle
nut just enough to hold the grinding wheel rmly
to the Grinder. DO NOT over-tighten the nut.
Excessive clamping force can damage the grinding wheel. Only use the wheel anges provided
with the grinder. Use only properly sized wheels
(diameter, width and bore) and verify that the
grinding wheel has a higher R.P.M. rating than
the maximum R.P.M. of the machine.
7. DO NOT USE A WHEEL THAT VIBRATES.
Dress the grinding wheel, replace it, or replace
the bearings of the shaft. Unsuitable grinding
wheels can come apart, throwing fragments that
may cause injury to you or the machine.
8. THE DIAMETER OF THE GRINDING
WHEELS WILL DECREASE WITH USE. Adjust
the tool rests and any jigs to maintain a safe
distance of 1/8” or less from the wheel.
9. DO NOT STAND IN FRONT OF THE BENCH
GRINDER WHEN STARTING IT. Stand to one
side of the Grinder and turn it “ON”. Wait at the
side until the grinder comes up to full speed.
There is always a possibility that debris from a
damaged grinding wheel may be discharged
towards the operator.
10. ALLOW THE GRINDER TO ATTAIN FULL
SPEED BEFORE BEGINNING WORK.
11. NEVER START THE MACHINE with the
workpiece against the grinding wheel. The
workpiece can be drawn into the wheel, causing
damage to the machine and/or serious injury.
12. NEVER GRIND ON A COLD WHEEL. Run
the sharpener for one full minute before applying
the workpiece. A cold wheel has a tendency to
chip. Those fragments could y from the wheel at
high speeds.
13. NEVER FORCE THE WORK PIECE
AGAINST A GRINDING WHEEL, especially if the
wheel is cold. Apply the work piece slowly, allowing the grinding wheel an opportunity to warm up.
This will minimize the chance of wheel breakage.
14. GRIND A WORKPIECE using the face of
the grinding wheel only. DO NOT grind using
the sides of the grinding wheels. Damage to the
wheel and a loss of control of the workpiece can
cause serious injury.
15. NEVER GRIND NEAR FLAMMABLE GAS
OR LIQUIDS. Sparks can create a re or an
explosion.
16. KEEP THE TOOL RESTS FIRMLY IN
PLACE AND TIGHTENED. Use them along with
any tool-holding jigs to safely hold and position
your material for grinding.
SAFETY INSTRUCTIONS
Page 6
24. NEVER STOP THE GRINDER BY FORCING
MATERIAL INTO THE WHEEL. Let the grinder
stop rotating on its own.
25. TURN THE MACHINE OFF, disconnect the
machine from the power source, empty the water
from the tray so that the stone will not rest in the
water for long periods which can weaken the
bonding strength of the grinding wheel and cause
it to fail, and clean the table/work area before
leaving the machine.

19. SAVE THESE INSTRUCTIONS. Refer to them
frequently and use them to instruct others.
17. CLEAN THE MACHINE thoroughly when
processing dierent types of workpieces (steel,
aluminium, etc.). Combining metal and wood dust
can create an explosion or re hazard. DO NOT
GRIND or polish magnesium. Fire will result.
18. ALWAYS USE a tool rest or tool-holding
jigs, and grasp the workpiece rmly with both
hands when grinding. Loss of control of the workpiece can cause serious injury. AVOID awkward
operations and hand positions. A sudden slip
could cause a hand to move into the grinding
wheel. The abrasive surfaces can cause injury.
19. PROPERLY SUPPORT LONG OR WIDE
workpieces. Loss of control of the workpiece
can cause serious injury.
20. NEVER GRIND SMALL STOCK without it
being properly supported on the tool rests, and
held by pliers or clamps.
21. DO NOT TOUCH the ground portion of a
workpiece until it has cooled suciently. Grinding
creates heat and may burn you if touched.
22. DO NOT FORCE THE TOOL to perform an
operation for which it was not designed. It will do
a safer and higher quality job by only performing
operations for which the tool was intended.
23. DRESS THE GRINDING WHEEL OFTEN.
This will keep the wheel surface at and free of
nicks and residue/glaze. RESURFACE ONLY
THE FACE OF THE GRINDING WHEEL. Dress-
ing the side of the wheel could cause it to become
too thin for safe use.
ELECTRICAL SAFETY
THIS TOOL MUST BE
GROUNDED WHILE IN USE TO PROTECT THE
OPERATOR FROM ELECTRIC SHOCK.
IN THE EVENT OF A MALFUNCTION OR
BREAKDOWN, grounding provides the path of
least resistance for electric current and reduces
the risk of electric shock. This tool is equipped
with an electric cord that has an equipment
grounding conductor and a grounding plug. The
plug MUST be plugged into a matching electrical
receptacle that is properly installed and grounded
in accordance with ALL local codes and
ordinances.
DO NOT MODIFY THE PLUG PROVIDED.
If it will not t the electrical receptacle, have the
proper electrical receptacle installed by a qualied
electrician.
IMPROPER ELECTRICAL CONNECTION of the
equipment grounding conductor can result in risk
of electric shock. The conductor with the green
insulation (with or without yellow stripes) is the
equipment grounding conductor. DO NOT
