2 Work Sharp Knife & Tool Sharpener
Safety Information
You will be creating incredibly sharp knives and
tools with this sharpener. Please handle them with
care. Use caution to avoid cutting yourself.
General Safety Rules
WARNING! Read all instructions. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious injury. The term “power
tool” in all of the warnings listed below refers to your corded power tool.
SAVE THESE INSTRUCTIONS
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
b) Do not operate power tool in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will reduce risk of electric
shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled cords increase the risk of
electric shock.
e) When operating a power tool outdoors, use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired
User’s Guide 3
or under the influence of drugs, alcohol or medication. A moment of
inattention while operating power tool may result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off-position
before plugging in. Carrying power tools with your finger on the switch or
plugging in power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool
on. A wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry
or long hair can be caught in moving parts. Air vents often cover moving
parts and should also be avoided.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at the rate
for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and must be
repaired.
c) Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting the power tool
accidentally.
d) Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to operate
the power tool. Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the
power tools operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and belts etc., in accordance with
these instructions and in the manner intended for the particular type
of power tool, taking into account the working conditions and the
4 Work Sharp Knife & Tool Sharpener
work to be performed. Use of the power tool for operations different from
those intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.
Specific Safety Rules
• Hold tool by insulated gripping surfaces when performing an operation
where the abrasive belt may contact hidden wiring or its own cord.
Contact with a “live” wire will make exposed metal parts of the tool “live” and
shock the operator.
• Always hold tool firmly.
• Use clamps or another practical way to secure and support the work
piece to a stable platform. Holding the work by hand or against your body
leaves it unstable and may lead to loss of control.
• WARNING: ALWAYS use proper safety glasses. Everyday eyeglasses are NOT
safety glasses. Also use face or dust mask if operation is dusty. ALWAYS WEAR
CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI 512.6 (53.19) hearing protection,
• NI05H/OSHA respiratory protection.
• WARNING: Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals known to
cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products,
and
• arsenic and chromium from chemically-treated lumber (CCA).
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 filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding, sawing, grinding,
drilling, and other construction activities. Wear protective clothing
and wash exposed areas with soap and water. Allowing dust to get into
your mouth, eyes, or lie on the skin may promote absorption of harmful
chemicals.
User’s Guide 5
• WARNING: Use of this tool can generate and/or disperse dust, which may
cause serious and permanent respiratory or other injury. Always use NIOSH/
OSHA approved respiratory protection appropriate for the dust exposure.
Direct particles away from face and body.
• CAUTION: Wear appropriate hearing protection during use. Under some
conditions and duration of use, noise from this product may contribute
to hearing loss.
SAFETY GUIDELINES — DEFINITIONS
It is important for you to read and understand this manual. The information it
contains relates to protecting YOUR SAFETY and PREVENTING PROBLEMS.
The symbols below are used to help you recognize this information.
• DANGER: Indicates an imminently hazardous situation which, if not avoided,
will result in death or serious injury.
• WARNING: Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
• CAUTION: Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury.
CAUTION: Used without the safety alert symbol (•) indicates a potentially
hazardous situation which, if not avoided, may result in property damage.
The label on your tool may include the following symbols.
V .................. volts A .............amperes
Hz ................ hertz W ............watts
min .............. minutes
............. direct current
................ Class II Construction ...........earthing terminal
...........alternating current
n
o ............no load speed
• ................ safety alert symbol rpm .........revolutions or
reciprocations per minute
Motor
Be sure your power supply agrees with nameplate marking. 120 Volts AC
only means your tool will operate on standard 60 Hz household power. Do
not operate AC tools on DC. A rating of 120 volts AC/DC means that your
tool will operate on standard 60 Hz AC or DC power. This information is
printed on the nameplate. Lower voltage will cause loss of power and can
result in over-heating.
6 Work Sharp Knife & Tool Sharpener
Extension Cords
When using an extension cord, be sure to use one heavy enough to carry
the current your product will draw. An undersized cord will cause a drop
in line voltage resulting in loss of power and overheating. The following
table shows the correct size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gage. The smaller the gage
number, the heavier the cord.
