Safety Information
FOR YOUR OWN SAFETY READ AND
UNDERSTAND THIS OPERATOR’S MANUAL
BEFORE OPERATING GRINDER
Keep this manual for future reference. To
ensure the correct use of the grinder and to
prevent accidents, do not start working without
having read this manual carefully. The manual
explains how the various components work
and provides instructions for carrying out the
necessary checks and maintenance operations.
SAFETY RULES AND PRECAUTIONS
WARNING The use of accessories or
attachments not recommended by the manufacturer
may result in a risk of injury to operator or
bystander. Any maintenance operation not
described in this manual must only be carried
out by an AUTHORIZED service center.
WARNING Replace cracked or damaged grinding
wheel immediately. Serious injury to operator or
bystander could result from a damaged wheel.
CAUTION The following instructions
should be carefully followed in order to
reduce the risk of kickback resulting from
improperly sharpened saw chain.
USERS
The grinder must only be used by adults.
Users must be in good physical condition and
familiar with the instructions for use.
KEEP BYSTANDERS AND CHILDREN AWAY
All bystanders should be kept at a
safe distance from work area.
WEAR PROPER APPAREL
Never wear loose clothing, bracelets, neckties, rings
or any other jewelry that could come into contact
or get caught with the grinding wheel or any other
moving parts. Nonslip footwear is recommended.
Wear protective hair covering to contain long hair.
ALWAYS USE SAFETY GLASSES
AND GLOVES
Always wear gloves and protective eyewear
while operating the grinder and while retouching
the grinding wheel using the dressing stone.
Also use face or dust mask if cutting operation
is dusty. Everyday eyeglasses only have impact
resistant lenses, they are NOT safety glasses.
NEVER STOP THE WHEEL WITH YOUR HANDS
Never attempt to stop the rotation of the
grinding wheel with your hands.
DISCONNECT TOOLS BEFORE SERVICING
Make sure the plug is disconnected when fitting
or changing the grinding wheel and during any
other operation of maintenance or transport.
KEEP GUARDS IN PLACE AND IN WORKING ORDER
Never start the grinder without
the wheel guards in place.
REMOVE ADJUSTING KEYS AND WRENCHES
Make sure that keys and adjusting wrenches
are removed from tool before turning it on.
DON’T FORCE TOOL
It will do the job better and safer at the rate for which
it was designed. Each grinder has a plate indicating:
–Size of arbor: Ø .87" (22.2 mm)
–No-load speed in revolutions per minute: RPM 5000
–Always read operator’s manual
before operating the machine
–Always wear eye and face protection
–Always use the proper grinding wheel
Also make sure that the voltage and frequency
indicated on the plate applied to the grinder
correspond to those of the mains hook-up.
REDUCE THE RISK OF UNINTENTIONAL STARTING
Always make sure that the start-up switch is in the “0"
(OFF) position before connecting the plug to the outlet.
NEVER USE CABLES, PLUGS OR EXTENSION
CABLES THAT ARE DEFECTIVE OR NON-STANDARD
See “Minimum Extension Cord Gauges” table on page
8. Remove the plug from the mains immediately
if the cable is damaged or cut; for cable repair or
replacement, contact your authorized dealer or
service center. The power supply cable is complete
with terminals – with protection. The internal
electrical connection consists of inserting the
feeding cable terminals directly in the switch. The
electrical connection to the mains shall be made
in such a way as to prevent damage by people or
vehicles which could endanger both them and you.
KEEP WORK AREA CLEAN
Cluttered areas and benches invite accidents. Make
sure that the grinding wheel working area is free of
tools or other objects before starting up the grinder.
Frequently clean grinding dust from beneath grinder.
DON’T USE IN DANGEROUS ENVIRONMENTS
Don’t use power tools in damp or wet location, or
expose them to rain. Keep work area well lighted.

Placing the Chain in the Vise
WARNING
–Wear personal protective equipment.
–All adjustments must be made with the motor switched off and the grinding wheel completely stopped.
–In the case of accidental impact or collision of the grinding wheel during the sharpening process, follow the
instructions given in the “CHOOSING AND INSTALLING THE GRINDING WHEEL – WARNINGS” section.
–To avoid overloading the motor excessively and to avoid damaging the chain cutters,
remove minimum amount of material with a tapping action and avoid holding the grinding
wheel on the cutter continuously as this will cause the cutting edge to burn.
–Do not use cooling liquids during the sharpening process.
–Clean the chain before sharpening it.
–Check the cutters and find the one with the most damage, you will want to start with this cutter.
–Ensure chain is placed in vise as shown, cutter direction heading toward right.

Placing the Chain in the Vise
This forward movement corresponds to the quantity
of material to be ground from the cutter. The more
dull or damaged the cutters, the greater this forward
movement should be. For cutters that are not too
dull, simply grind a slight amount of material.
It is also important not to grind too much
material in one pass. This could result in
“burning” the cutter, reducing its hardness,
and causing excessive burrs.
Turn depth adjustment knob (6) to adjust the
cutter sharpening depth. The grinding wheel (C)
should skim the bottom of the cutter vertically.
Once you have found the exact position of the cutter,
tighten the vise clamp by depressing the red button
and rotating the vise handle (9) clockwise. You
are now ready to begin sharpening your chain.
