GENERAL SAFETY RULES

Safety is a combination of common sense, staying alert and knowing how your item works.

SAVE THESE SAFETY INSTRUCTIONS.

WARNING: Read and understand all warnings, cautions and operating instructions before using
this tool. Failure to follow all instructions listed below may result in personal injury and tool damage.

WORK AREA SAFETY

1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.

2. Do not operate power tools 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.

3. Do not expose power tools to rain or wet conditions (except for the water reservoir and grinding wheel).
Water entering a power tool will increase the risk of electric shock.

4. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.

ELECTRICAL SAFETY

1. 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.

2. 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.

3. 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.

4. If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI reduces the risk of electric shock.

PERSONAL SAFETY

1. 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 or under the influence of drugs, alcohol or medication. A moment of inatten­tion while operating power tools may result in serious personal injury.

2. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust
mask, non-skid safety shoes and hearing protection used for appropriate conditions will reduce the risk of
personal injury.

3. 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.

4

GENERAL SAFETY RULES

4. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites accidents.

5. 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.

6. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power
tool in unexpected situations.

7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can reduce dust-related hazards.

POWER TOOL USE AND CARE

1. 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.

2. 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.

3. Disconnect the plug from the power source and/or the battery pack from the power tool before making
any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.

4. 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

ELECTRICAL INFORMATION

GROUNDING INSTRUCTIONS

This tool is equipped with an electric cord that has an equipment grounding conductor and a grounding plug.
In the event of a malfunction or breakdown, grounding provides the path of least resistance for an electric
current and reduces the risk of electric shock. The plug must be plugged into a matching outlet that is prop­erly installed and grounded in accordance with all local codes and ordinances (Fig. A).

1. USE ONLY THREE-WIRE EXTENSION CORDS that have three-pronged
plugs and outlets that accept the tool’s plug as shown in Fig. A. Do not
modify the plug provided. If it will not fit the outlet, have the proper
outlet installed by a licensed electrician.

2. IMPROPER CONNECTION of the equipment grounding conductor can
result in electric shock. The conductor with the green insulation (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.

3. Repair or replace a damaged or worn cord immediately. Servicing of electrical components should only be
done by a certified electric technician.

Fig. A

IMPORTANT: Check with a licensed electrician or service personnel if you do not completely understand the

grounding instructions or whether the tool is properly grounded.

GUIDELINES AND RECOMMENDATIONS FOR 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 table
below shows the correct size to be used according to cord length and ampere rating. When in doubt, use a
heavier cord. The smaller the gauge number, the heavier the cord.

AMPERAGE

25 ft. 50 ft. 100 ft. 150 ft.

1.25A 18 gauge 16 gauge 16 gauge 14 gauge

1. EXAMINE EXTENSION CORD BEFORE USE. Make sure your extension cord is properly wired and in good
condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.

2. DO NOT ABUSE EXTENSION CORD. Do not pull on cord to disconnect from receptacle; always disconnect
by pulling on plug. Disconnect the extension cord from the receptacle before disconnecting the product from
the extension cord. Protect your extension cords from sharp objects, excessive heat and damp/wet areas.

REQUIRED GAUGE FOR EXTENSION CORDS

3. USE A SEPARATE ELECTRICAL CIRCUIT FOR YOUR TOOL. This circuit must not be less than a 12-gauge wire
and should be protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make
sure the switch is in the OFF position and the electric current is rated the same as the current stamped on
the motor nameplate. Running at a lower voltage will damage the motor.

• Against wheel rotation

Working against the rotation of the blade removes
larger amounts of material quickly. Use this method
for shaping blades or sharpening axes.

To grind AGAINST the direction of the wheel rotation,
place the work support in the VERTICAL mounts (A).

• Along wheel rotation
Working along the rotation of the blade is preferable

for more precise jobs that require less material re­moval. For fine sharpening on tools such as knives,
scissors, or other carving instruments, grind with the
rotation of the wheel.

For grinding and honing ALONG the direction of the
wheel rotation, place the work support in the hori­zontal mounts (B).
