For safe operations:
1. Keep work area clean.
Cluttered areas and benches invite injuries.
2. Consider work area environment.
Do not expose power tools to rain. Do not use
power tools in damp or wet locations. Keep work
area well lit. Do not use power tools where there is
risk to cause fire or explosion.
3. Guard against electric shock.
Avoid body contact with earthed or grounded sur-
faces (e.g. pipes, radiators, ranges, refrigerators).
4. Keep children away.
Do not let visitors touch the tool or extension cord.
All visitors should be kept away from work area.
5. Store idle tools.
When not in use, tools should be stored in a dry,
high or locked up place, out of reach of children.
6. Do not force the tool.
It will do the job better and safer at the rate for which
it was intended.
7. Use the right tool.
Do not force small tools or attachments to do the job
of a heavy duty tool. Do not use tools for purposes
not intended; for example, do not use circular saws
to cut tree limbs or logs.
8. Dress properly.

caught in moving parts. Rubber gloves and non-skid
footwear are recommended when working out-
doors. Wear protecting hair covering to contain long
hair.
9. Use safety glasses and hearing protection.
Also use face or dust mask if the cutting operation is
dusty.
10. Connect dust extraction equipment.
If devices are provided for the connection of dust
extraction and collection facilities ensure these are
connected and properly used.
11. Do not abuse the cord.
Never carry the tool by the cord or yank it to discon-
nect it from the socket. Keep the cord away from
heat, oil and sharp edges.

determine that it will operate properly and perform
its intended function. Check for alignment of moving
parts, free running of moving parts, breakage of
parts, mounting and any other conditions that may
affect its operation. A guard or other part that is
damaged should be properly repaired or replaced
by an authorized service center unless otherwise
indicated in this instruction manual. Have defective
switches replaced by an authorized service facility.

ADDITIONAL SAFETY RULES ENB052-2
1. This tool is equipped with a portable residual
current device. Do not connect the tool to a
power supply without using the PRCD (Portable
Residual Current Device). In case of damage of
the cord, it has to be replaced by the manufac-
turer’s service organization.
2. For additional protection against electric shock,
be sure to WEAR RUBBER GLOVES AND RUB-
BER BOOTS during operation.
3. Check the wheel carefully for cracks or damage
before operation. Replace cracked or damaged
wheel immediately.
4. Use only flanges specified for this tool.
5. Be careful not to damage the spindle, flanges
(especially the installing surface) or bolt. Dam-
age to these parts could result in wheel break-
age.
6. When using the water feed, be careful not to let
water get into the motor. If water runs into the
motor, an electric shock hazard may result.
7. Hold the tool firmly.
8. Keep hands away from rotating parts.

thing abnormal.
12. Never attempt to cut with the tool held upside
down in a vise. This can lead to serious acci-
dents, because it is extremely dangerous.(Fig.

The inner flange has a 25 mm diameter on one side and 25.4 mm diameter on
the other. The side with 25.4 mm diameter is marked by “25.4”. Use the cor-
rect side for the hole diameter of the wheel you intend to use. Mounting the
wheel on the wrong side can result in dangerous vibration.
Water flow
Attach the vinyl tube onto the water pipe and attach the adapter on the vinyl
tube to a faucet of water mains pressure. Adjust the amount of water flow by
simply adjusting the water cock.
CAUTION:
•Adjust the water cock so that the water flow rate does not exceed 1.2
liters per minute.
OPERATION
Adjust the amount of water flow. Hold the tool firmly. Set the base plate on the
workpiece to be cut without the wheel making any contact. Then turn the tool
on and wait until the wheel attains full speed. Now simply move the tool for-
ward over the workpiece surface, keeping it flat and advancing smoothly until
the cutting is completed. Keep your cutting line straight and your speed of
advance uniform.
CAUTION:
•THIS TOOL SHOULD ONLY BE USED ON HORIZONTAL SURFACES.
•Be sure to move the tool forward in a straight line and gently. Forcing
and exerting excessive pressure or allowing the wheel to bend, pinch or
twist in the cut can cause overheating of the motor and dangerous
kickback of the tool.
MAINTENANCE CAUTION:
•Always be sure that the tool is switched off and unplugged before
attempting to perform inspection or maintenance.
After use
Blow away dust from the inside of the tool by running the tool at an idle for a
while. Brush off accumulation of dust on the base. Accumulation of dust in the

and wipe it. Then install the cover (A) on the tool so that its side with “Upside
”mark faces upward. Push the cover (A) toward the motor as far as it will go
and secure it by tightening the clamp.
When changing the wheel, clean the cover (B) at the same time. Loosen the
screw securing the cover (B) and remove the cover (B). Wash off accumulation
of dust inside the cover (B) and wipe it. Then attach the cover (B) to the tool by
tightening the screw. Accumulation of dust inside the covers may cause a mal-
function of the tool.
CAUTION:
•When using the tool, be sure to attach the covers (A) and (B).
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace when they wear
down to the limit mark. Keep the carbon brushes clean and free to slip in the
holders. Both carbon brushes should be replaced at the same time. Use only
identical carbon brushes.
First, remove the cover (A).
Use a screwdriver to remove the brush holder caps. Take out the worn carbon
brushes, insert the new ones and secure the brush holder caps.
