GENERAL SAFETY INSTRUCTIONS
Operang a Ulity Sharpener can be dangerous if safety and common sense are ignored. The operator
must be familiar with the operaon of the tool. Read this manual to understand this Ulity Sharpener.
DO NOT operate this Ulity Sharpener if you do not fully understand the limitaons of this tool. DO NOT
modify this Ulity Sharpener in any way.
BEFORE USING THE UTILITY SHARPENER
To avoid serious injury and damage to the tool, read and follow all of the Safety and Operang Instruc-
ons before operang the Ulity Sharpener.
1. Some dust created by using power tools contains chemicals known to cause cancer, birth defects, or
other reproducve 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 oen you do this type of work. To reduce
your exposure to these chemicals: work in a well-venlated area, and work with approved safety
equipment, such as dust masks that are specially designed to lter out microscopic parcles.
2. READ the enre Owner’s Manual. LEARN how to use the tool for its intended applicaons.
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 protecon against elec-
tric shock. DO NOT remove the 3rd prong. See grounding instrucons on page 6.
4. AVOID A DANGEROUS WORKING ENVIRONMENT. DO NOT use electrical tools in a damp environ-
ment or expose them to rain.
5. DO NOT use electrical tools in the presence of ammable liquids or gases.
6. ALWAYS keep the work area clean, well lit and organised. DO NOT work in an environment with
oor surfaces that are slippery from debris, grease or wax.
7. KEEP VISITORS AND CHILDREN AWAY. DO NOT permit people to be in the immediate work area,
especially when the electrical tool is operang.
8. DO NOT FORCE THE TOOL to perform an operaon for which it was not designed. It will do a safer
and higher quality job by only performing operaons for which the tool was intended.
9. WEAR PROPER CLOTHING. DO NOT wear loose clothing, gloves, neckes, or jewellery. These items
can get caught in the machine during operaons and pull the operator in to the moving parts. You
must wear protecve cover on your hair, if your hair is long, to prevent it from contacng any mov-
ing parts.

SAFETY INSTRUCTIONS (cont.)
10. ALWAYS WEAR EYE PROTECTION. Any power tool can throw debris into the
eyes during operaons, which could cause severe and permanent eye damage.
Everyday eyeglasses are NOT safety glasses.
11. ALWAYS WEAR HEARING PROTECTION. Plain coon is not an acceptable protecve device. Hearing
equipment should comply with ANSI S3.19 Standards.
12. ALWAYS UNPLUG THE TOOL FROM THE ELECTRICAL RECEPTACLE when making adjustments,
changing parts or performing any maintenance.
13. KEEP PROTECTIVE GUARDS IN PLACE AND IN WORKING ORDER.
14. AVOID ACCIDENTAL STARTING. Make sure that the power switch is in the “OFF” posion before
plugging in the power cord to the electrical receptacle.
15. REMOVE ALL MAINTENANCE TOOLS from the immediate area prior to turning “ON” the Ulity
Sharpener.
16. USE ONLY RECOMMENDED ACCESSORIES. Use of incorrect or improper accessories could cause se-
rious injury to the operator and cause damage to the tool. If in doubt, check the instrucon manual
that comes with that parcular accessory.
17. NEVER LEAVE A RUNNING TOOL UNATTENDED. Turn the power switch to the “OFF” posion. DO
NOT leave the tool unl it has come to a complete stop.
18. DO NOT STAND ON THE TOOL. Serious injury could result if the tool ps over or you accidentally
contact the tool.
19. DO NOT store anything above or near the tool where anyone might try to stand on the tool to reach
it.
20. MAINTAIN YOUR BALANCE. DO NOT extend yourself over the tool. Wear oil resistant rubber soled
shoes. Keep oor clear of debris, grease and wax.
21. MAINTAIN TOOLS WITH CARE. Always keep tools clean and in good working order. Keep all blades
and tool bits sharp.
22. 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 func-
ons. Check for alignment, binding or breaking of moving parts. A guard or other part that is dam-
aged should be immediately repaired or replaced.
23. CHILDPROOF THE WORKSHOP AREA by removing switch keys, unplugging tools from the electrical
receptacles, and using padlocks.
24. DO NOT OPERATE TOOL IF UNDER THE INFLUENCE OF DRUGS OR ALCOHOL.
25. SECURE ALL WORK. Use clamps or jigs to secure the workpiece. This is safer than aempng to
hold the workpiece with your hands.

KNOW YOUR UTILITY SHARPENER
The Ulity Sharpener is designed with numerous features to quickly and safely sharpen various items
around the house and shop. A ne grit grinding wheel is used to produce a sharp and precise cung
edge. Two mul-posion tool rests provide a rm work surface at a variety of angles. A water trough is
used to keep the grinding wheel and the workpiece cool during sharpening operaons., The Ulity Sharp-
ener addionally has been ouied with an electrical power switch that permits the grinding wheel to
rotate in the Forward and Reverse direcons.
The Ulity Sharpener will put a sharp edge on knives, scissors, and at chisels with a minimal amount of
eort and skill needed by the user. Sharp tools cut more quickly, safely and eciently. A dull edge will
require the user to apply more pressure to the workpiece, possibly causing injury to the user. Keeping the
cung tools sharp will provide many years or useful service. Periodic sharpening will prevent the tools
from losing the bevel that was put on by the manufacturer originally. The factory bevel is what you
should use when sharpening any tool.

5
KNOW YOUR UTILITY SHARPENER (cont.)
Sharpening is an easy operaon to perform as long as the following items are followed:
1. CLEAN the item to be sharpened prior to beginning any sharpening operaons.
2. ALWAYS use the factory bevel (cung edge angle) as a guide to sharping the tool.
3. SHARPEN the tools prior to starng any job involving the tools. The user will then be less likely to
rush the sharpening procedure, and then will do a safer and beer job.
4. SHARPEN the tools in numerous light pressure passes instead of heavily pressing the tool against
the grinding wheel. Light passes will be safer and produce a much sharper edge on the tool. Heavy
passes will create a ragged and rough edge on the tool.
5. DO NOT sharpen tools that are cracked or bent. A damaged tool should be discarded.
6. The Ulity Sharpener IS NOT to be used as a Bench Grinder to remove large amounts of material.
The grinding wheel rotates much slower than a Bench Grinder. The grinding wheel uses a much n-
er grit grinding wheel than a Bench Grinder’s grinding wheel.

6
OPERATING THE UTILITY SHARPENER
The Ulity Sharpener is designed for sharpening knives, scissors, at chisels, and more.
ALWAYS WEAR EYE PROTECTION! Hot sparks may be produced during sharpening operaons.
1. The electrical power switch must be in the OFF posion.
2. The power cord must be unplugged from the electrical receptacle.
3. Place the Ulity Sharpener on at, rm, and water resistant surface.
4. Loosed the two lock knobs that hold the front tool rest unl the tool rest can be moved away from
the stone. The lock knobs may be reposioned by pulling the knob out slightly. This permits the
knob to be rotated for addional loosening or ghtening.
5. Parally ll a measuring cup with tap water. Proceed to
slowly pour approximately 80mls - 180mls of water over
the stone as shown in Fig. C.
Do not have the Ulity Sharpener operang while pouring
the water. The rotang grinding wheel will cause water to
be splashed possibly on to the electrical switch.
6. Plug in the power cord and turn ON the Ulity Sharpener. Let the tool run for one minute. This will
let the grinding wheel absorb some of the water and provide a cool grinding surface.
7. Aer one minute, turn OFF the Ulity Sharpener and unplug the power cord from the electrical re-
ceptacle. Proceed to ll water trough unl water is almost about to spill out of the drainage opening
in the rear of the Ulity Sharpener.
8. The Water Trough will need to be relled occasionally during extended sharpening operaons.
9. Return the front tool rest back into posion.
10. Adjust both the front and rear tool rests unl they are approximately 1/8” from the grinding wheel.
Firmly ghten all four of the lock knobs.
11. Carefully inspect the item to be sharpened. Look for any cracks or bends. If the item is damaged,
then discard it. DO NOT aempt to sharpen a damaged tool.

OPERATING THE UTILITY SHARPENER (cont.)
12. If the item to be sharpened is in good condion, then proceed to lay the item at on either of the
tool rests as shown in Fig. D. Loosen the lock knobs and adjust the tool rest unl the original bevel
angle of the item to be sharpened is matched. Maintain a 1/8” distance from the grinding wheel
aer the tool rest has been adjusted to the proper angle. Firmly ghten the lock knobs.
NOTE: To sharpen scissors, hold as shown in Fig. E. You must sharpen the bevel side of each scissors
blade. DO NOT aempt to sharpen the at side of the blade. This will ruin the scissors.
13. Pracce a few mes while the Ulity Sharpener is OFF, slowly pulling the tool across the grinding
wheel while keeping the tool at on the tool rest. ALWAYS pull the item to be sharpened across the
wheel from the angle to the p of the blade. DO NOT ever push the item across the grinding wheel.
14. Plug the power cord in to the electrical receptacle and turn ON the Ulity Sharpener. Ordinarily,
cung edges are sharpened with the grinding wheel turning toward the blade. However, if you nd
it more comfortable, you may sharpen with the wheel turning away from the blade.
15. Proceed to lay the item to be sharpened at onto the tool rest and hold onto it rmly with both
hands. Slowly and lightly pull the item across the rotang grinding wheel. Inspect the item aer a
few passes to check the progress. The cung edge should have a shiny appearance the enre
length of the cung surface. If the surface has dark and shiny spots, the angle of the tool rest is not
properly adjusted or the user is not keeping the item at on the tool rest. Make adjustments as nec-
essary.
16. Alternate sharpening on both sides of the tool.
17. Upon compleng the sharpening operaons, a small burr might form on the cung edge. Remove
the burr by turning the Ulity Sharpener OFF and unplugging it from the electrical receptacle. Light-
ly pull the blade across the staonary grinding wheel unl the small burr is removed.
18. Dump out the water that was poured into the water trough earlier by lng the Ulity Sharpener
backward.
19. Wipe the Ulity Sharpener o with a clean dry rag and inspect for any damage to the grinding
wheel.

MAINTENANCE
Turn the power switch “OFF” and unplug the power cord from its power source prior to any mainte-
nance.
CLEANING
With the Ulity Sharpener unplugged, rotate the abrasive wheel slowly and inspect for any damage.
CAUTION: REPLACE the abrasive wheel if there is any damage at all. FAILURE to replace a damaged wheel
can cause serious injury to the operator.
CAUTION: DO NOT USE FLAMMABLE MATERIALS to clean the Ulity Sharpener. A clean dry rag or brush
is all that is needed to remove dust and debris build-up.
Repairs to the Ulity Sharpener should be performed by trained personnel only. Contact your retailer for
authorized service. Unauthorized repairs or replacement with non-factory parts could cause serious injury
to the operator and damage to the Ulity Sharpener.
TO PREVENT INJURY TO YOURSELF or damage to the Ulity Sharpener, turn the switch to “OFF” posion
and unplug the power cord from the electrical receptacle before making any adjustments.
