WORK AREA SAFETY
1. Keep your work area clean and well lit. Cluttered benches and dark areas increase the
chance of 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. Keep bystanders, children, and visitors away while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
DANGER
1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use
any adapter plugs. Unmodified plugs and matching outlets will reduced risk of electric
shock.
2. Avoid body contact with 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 expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord to carry the power tool or pull the plug from

3. Preparation & adjustment
3.1 Assembly
The EUROBOOR ERM.100/3 comes pre-assembled. The only adjustments that need to be
made before you can start working with this machine is: fitting the corresponding annular
cutter holder and fitting the correct indexing plate for your job. Then the machine is ready to
fit the annular cutter and start resharpening! The EUROBOOR ERM.100/3 sharpening machine
sharpens HSS cutters between ø 12 mm (1/2″) and 44 mm (1 3/4″) in cutting depths between
25 mm (1″) and 55 mm (2 3/16″) with great ease. The laser guided cutter alignment ensures
correct positioning of the cutting edge to the wheel where the easy angle adjustments makes
alignment to the original geometry easy and simple.
