Safety Precautions
Additional safety
precautions have to be
observed when operating
the universal sharpener.
It is important that you
read and understand the
owner’s manual before
using your tool for the first
time. Keep it in a safe
place for later reference.
Non-observance of the following safety
precautions may cause serious or even
fatal injury.
Always observe local safety regulations,
standards and ordinances.
If you have never used this sharpener
model before:
Have your dealer or a trained expert
show you how to operate it properly and
safely.
Only use the grinding wheels supplied
by STIHL or expressly approved by
STIHL for use with your specific model.
Do not use any other grinding wheels
since they will increase the risk of injury.
Switch on the motor only if its operating
voltage agrees with the voltage of your
power supply.
Clothing and Equipment
Wear proper protective clothing and
equipment.
The grinding dust produced when using
this sharpener may cause health
problems. Always use a dust extractor
or wear a suitable respirator.
The sparks created during sharpening
may cause eye injuries.
Always wear safety
glasses.
Minors should never be allowed to use
an electric sharpener.
Keep children, bystanders and animals
well clear of the work area.
Wear heavy-duty, nonslip gloves, preferably
made of leather.
Clothing must be sturdy and snug-fitting,
but allow complete freedom of
movement.
Wear overalls – avoid loose-fitting
jackets.
Before Starting Work
Check that your sharpener is properly
assembled and in good condition. Do
not operate your sharpener with a
damaged connecting cord or grinding
wheel.
Maintenance and Repairs
Always disconnect the unit from the
power supply before carrying out any
maintenance work. Only perform the
adjustments and maintenance
operations described in this manual.
All other maintenance and repairs
should be carried out by your STIHL
dealer.
Only use original STIHL replacement
parts.
In the interests of your own safety, never
modify your electric sharpener in any
way.
Wear steel-toed safety
boots with non-slip soles.

Applications
Mounting the Tool
The STIHL USG sharpens all STIHL
Oilomatic saw chains, hedge trimmer
blades and circular saw blades.
The unit may be mounted on a wall or
workbench.
Optional swivelling tool rests are
required for sharpening scratcher tooth
chain, hedge trimmer blades and
circular saw blades.
If you mount the unit on a bench, note
that the unit must overhang the bench by
at least 120 mm.
A
If you use the special attachment for
hedge trimmer blades:
If you mount the unit on a wall, note that
a clearance of at least 450 mm is
required between the wall and the unit
for sharpening hedge trimmer blades.
Recommendation: Mount the unit on a
bench for such work.
523BA045 KN

Secure the unit with screws
A = For wall mounting, use three
suitable 8 mm dia. screws (e.g.
8 mm x 100 mm wood screws,
DIN 571-St), 8.4 mm dia. washers
and suitable wall plugs (e.g.
10x50 mm plastic wall plugs)
B = For bench mounting, use two
suitable 8 mm dia. screws (e.g.
8 mm x 100 mm wood screws,
DIN 571-St), 8.4 mm dia. washers

In the case of bevel ground teeth,
mark the teeth that have the same
sharpening angle (every second
