This section contains safety information for the Oregon 710-120 Auto Chain Grinder. This manual contains
WARNINGS, CAUTIONS, and NOTES that are applicable for the safe operation of the machine.
DANGER Indicates a hazard with a high level of risk which, if not avoided, will result in death or
serious injury.
WARNING Indicates a hazard with a medium level of risk which, if not avoided, could result in death
or serious injury.
CAUTION Indicates a hazard with a low level of risk which, if not avoided, could result in minor or
moderate injury.
IMPORTANT Indicates a potential situation exists which, if not avoided, may result in damage to your
grinder or property.
2.2 General machine safety warnings
WARNING Read all safety warnings, instructions, illustrations, and specifications provided with this
machine. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious
injury. Save all warnings and instructions for future reference.
WARNING Keep work area clean and well lit. Cluttered or dark areas invite accidents.
WARNING Do not operate machines in explosive atmospheres, such as in the presence of flammable
liquids, gases, or dust. Machines create sparks which may ignite the dust or fumes.
WARNING Keep children and bystanders away while operating a machine. Distractions can cause you
to lose control.
WARNING Machine plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) machines. Unmodified plugs and matching outlets will reduce risk
of electric shock.
WARNING 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.
WARNING Do not expose machines to rain or wet conditions. Water entering a machine will increase
the risk of electric shock.
WARNING Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the machine.
Keep cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the
risk of electric shock.
WARNING If operating a machine in a damp location is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces the risk of electric shock.
WARNING Stay alert, watch what you are doing, and use common sense when operating a machine.
Do not use a machine while you are tired or under the influence of drugs, alcohol, or medication. A
moment of inattention while operating machines may result in serious personal injury.
WARNING Use personal protective equipment. Always wear eye protection. Protective equipment
such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
WARNING 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 machine. Carrying machines with your

Safety
WARNING Before a chain is sharpened, make sure that the grinding wheel is not cracked and does
not vibrate, or wobble. If the grinding wheel is damaged, it must be replaced immediately, see section
6.3, “Change the grinding wheel and fit the grinding wheel guard.” You can also do a simple “ring test” to
check for damage; see 4.5, “Installing the grinding wheel.” If abnormal vibrations occur during operation,
immediately stop the machine and check the condition of the grinding wheel.
WARNING Place the power converter where there is as little dust as possible and out of reach of
sparks from the machine.
WARNING Attach air hoses and cables with cable clamps to make sure no one trips over them.
CAUTION Only use accessories that are supplied or approved by the manufacturer.
CAUTION If the pitch is not correctly set, the chain will be pushed into an incorrect sharpening position.
This may result in a damaged chain.
CAUTION If the metal of a cutting link turns blue during grinding, the speed is set too high and the
metal is overheated. This can cause the metal in the cutting tooth to lose its sharpness. Replace the
damaged cutting link or sharpen the chain again.
CAUTION Grinding dust can interfere with the machine’s operation. Clean the machine daily to remove
all of the grinding dust. Use a vacuum cleaner, brush, or similar to clean the machine.

Installation
4.4 Bench-mounting the machine
1. Always mount the grinder securely, either
to a bench or to the optional stand (see
chapter 8.5).
2. Bench-mounting offers you flexibility and
the ability to sharpen chain virtually
anywhere using the electrical from any wall
outlet or use of a 12V power source.
3. To connect the AC/DC converter unit to the
machine, plug in the black and red power
cable into the control panel through the slot
on the left hand side of the machine
WARNING Put the power converter
where there is as little dust as possible and
out of reach of sparks from the machine.

the optional stand and the pneumatic
tensioner, it should be used with the weight
tensioner in order to provide the chain with
the tension needed for grinding.
1/16" (2 mm)
4.5 Installing the grinding wheel
Note: The first step in preparing the grinder for
use is installing the appropriate grinding wheel.
1. The grinder comes with three wheel sizes:
1/4" (6.4 mm), 3/16" (4.8 mm) and 1/8"
(3.2 mm). The wheels are 5 7/8" (150 mm)
in diameter with 5/8" (16 mm) arbor size.
It is critical to select the wheel of the
appropriate thickness for each chain.
2. The correct wheel size for a particular
Oregon saw chain can be found in
several sources: this manual, the back
of the Oregon chain packaging, Oregon
Maintenance and Safety Manual, or
online at OregonProducts.com.
WARNING Inspect the grinding wheel
and make sure that it is not cracked or
damaged. There is a simple test (called the
“ring test”) that you can do to check for
damage to a grinding wheel. Hold the
grinding wheel up by its center hole. Knock
the edge of the grinding wheel gently with a
non-metallic object (like the plastic handle
of a screwdriver). If the grinding wheel
makes a dull, non-metallic noise, then the
wheel could be damaged. DO NOT USE IT.
CRACKED GRINDING WHEELS MUST BE
REPLACED IMMEDIATELY. See also, 6.3,
“Changing the grinding wheel and fitting the
grinding wheel guard.”

Installation
6. Next, insert the appropriate wheel onto the
hub and, using moderate pressure with
your hands, secure the wheel attachment
nut to hold the wheel in place.
WARNING Over-tightening the wheel
can cause it to break.
7. Finally, reposition the shield and secure it in
place with the retaining screw.
WARNING Never start the grinder
without the wheel guards in place.
8. Before using the grinder, you’ll need to
check to ensure the wheel is properly
installed.
9. With the power off, gently spin the grinding
wheel and check for wheel wobble.
10. Conduct a final check for proper assembly
by turning on the main power and
switching on the wheel power switch
while standing to the side. Look for
vibrations due to wheel oscillation or other
interference.
WARNING Always keep bystanders
at a safe distance from a grinder while in
operation.
CAUTION The grind wheel is designed
to rotate away from the operator. This
safety feature reduces the likelihood of
sharp pieces of shrapnel striking the
operator should the wheel fracture or break
during the grinding process. Therefore,
do not stand behind the grinder when it is
operating.
Note: To get the best performance from
your grinder, ensure the grinding wheel
is centered over the vise. See step 14
of section 5.2.5, “Making the grinding
settings,” or the provided video for specific
instructions.
3. Once the grinding wheel has been verified,
you’re ready to begin the install.
4. Start by removing the grinding wheel shield
(C) to access the wheel attachment nut (B).
Use the provided Allen wrench to loosen
the retaining screw (D).
5. Remove the wheel attachment nut from
the hub.

5.1 Safety during operation
WARNING Before you install, operate, or
perform maintenance on the machine, you
must read the operators manual. Obey the
instructions in this manual to prevent injuries or
damage to the equipment.
WARNING Always wear safety gloves,
protective glasses, and any other personal
protective equipment suitable for your task.
WARNING To prevent mistakes when
chains are sharpened, it is very important to
understand how the grinding machine works.
Read the instructions carefully before the
machine is used.
5.2 Preparing for operation
Note: For a video demonstration of how
to install and operate the machine, go to
OregonProducts.com.
5.2.1 Preparing the grinding wheel
WARNING Before a chain is sharpened,
make sure that the grinding wheel is not
cracked, does not vibrate, or wobble. Perform
a “ring test”; see section 4.5, “Installing the
grinding wheel.” If the grinding wheel is
damaged, it must be replaced immediately; see
section 6.3, “Changing the grinding wheel and
fitting the grinding wheel guard.”
If abnormal vibrations occur during operation,
immediately stop the machine and check the
condition of the grinding wheel. Make sure all
the switches are turned off before turning the
power back on.
Note: Before each chain is sharpened, make
sure the grinding wheel edges match the shape
of the chain type.
The condition, type and profile of the grinding
wheel is essential for the machine’s accurate
operation. The instructions that follow contain
information on how to make sure that the
grinding wheel is in good condition and has the
correct profile.
1. Press the power button to turn on the
machine.
2. Set the grinding wheel switch to ON.
3. Make sure that the grinding wheel does not
vibrate or wobble. If the grinding wheel is
damaged, it must be replaced immediately;
see section 6.3, “Changing the grinding
wheel and fitting the grinding wheel guard.”
4. Make sure the grinding wheel edges match
the shape of the chain type.
• For ceramic grinding wheels: Use the
profile stone (included in delivery) to
shape the edges on the grinding wheel.
Use a light-sweeping action to shape the
edges of the wheel. Use the provided
template to verify proper radius shape for
the specific grinding wheel being used.

5. Set the grinding wheel switch to OFF.
6. Use the profile template to verify that the
grinding wheel has the same profile as the
type of chain to be sharpened.
7. Repeat steps 4-7 until the grinding wheel
profile is the same as the selected profile
on the profile template.
5.2.2 Setting the head-tilt angle
Note: Read the specifications from the chain
manufacturer to find out the recommended
head-tilt angle for your chain.
1. Loosen the head-tilt angle knob located on
the back of the machine.
2. Turn the grinding head to set the desired
head-tilt angle (50-90°) on the head-tilt angle
scale. The default head-tilt angle is 55°.
3. Tighten the head-tilt angle knob.
5.2.3 Setting the top-plate angle
Note: Read the specifications from the chain
manufacturer to find out the recommended
top-plate angle for your chain.
1. Use the hex key (provided with the
machine) to loosen the top-plate angle
screw up to three turns.
2. Turn the grinding head to set the desired
top-plate angle (0-35°) on the top-plate angle
scale. The default top-plate angle is 25°.
3. Tighten the top-plate angle screw.

4. Press the grinding head positioning button
to move the grinding head in both
directions and make sure that the top-plate
angles are the same.
5. If the top-plate angles are not the same (for
example 26° in the right direction and 30°
in the left direction), adjust the nuts (A) a
1/2-turn at the time.
6. Repeat steps 2-5 until the top-plate angles
are the same in both directions.
5.2.4 Inserting the chain
1. Check the chain for double-links (2 left
cutters or 2 right cutters) or joint-links, and
make sure that the chain is not damaged.
Mark double-links or joint-links to make
it easier to see them when the chain is
sharpened.
2. Attach the stop clamp on a tie-strap
between a double-link or a joint-link.

3. Place the chain, with the cutter to the left of
the depth gauge, into the groove on the
chain vise.
4. Attach the chain weight to the chain.
5. Pull the chain around by hand to make sure
that it runs freely in the chain vise.
CAUTION Always wear gloves and
protective eyewear while you work and
operate your grinder.
