SAFETY SYMBOLS AND WARNINGS
Used to draw special attention to operator and/or bystanders
to help prevent possible injury.
INSTALLING/DRESSING THE GRINDING WHEEL
There is the risk of severe personal injury from high speed ejection
of material. Read and follow all instructions in this manual.
Always wear eye protection.
A grinding wheel that has been
damaged or improperly installed may
crack and disintegrate during operation.
This can cause wheel fragments to eject
at very high rates of speed.
Always perform proper grinding wheel
maintenance, check for visible cracks
and perform a “ring test.” (A good
grinding wheel will sound a clear musical
tone when tapped gently with metal tool
like an Allen wrench.)
Do not force a grinding wheel onto the
machine or alter the size of the mounting
hole. Do not use a wheel that does not fit
exactly. Use of Oregon®grinding wheels
only is recommended.
Make sure the mounting flange nut is
serviceable and not damaged in any way.
If grinding wheel vibration should occur
when the grinder is started, or running,
stop the machine. Remove and inspect
the mounting flange and the grinding
wheel.
To minimize the risk of injury from
grinding wheel failure, always allow a
new grinding wheel to run at operating
speed for at least one minute before
grinding or dressing.
Do not use the side of the grinding wheel
for grinding.
Always work cautiously, maintain a strong
grip on the dressing brick, and watch
what you are doing.
Dressing the grinding wheel places the
fingers of the operator in close proximity
to the grinding wheel. Contact with a
rapidly turning wheel may result in injury.
Saw chain depth gauges not properly
filed/ground can substantially increase the
risk of kickback and injury. To reduce the
likelihood of kickback, always file/grind
depth gauges to original profile and follow
exactly sharpening instructions for your
saw chain.

ASSEMBLY INSTRUCTIONS
The grinder must be used only in a place that is protected from dust
and dampness, that is well-lighted, out of the reach of children, and away
from gases or other flammable or explosive liquids.The grinder must
be situated near a normal electrical outlet equipped with earth (grounded).**
Avoid using dangerous extension cords (See Table 1, page 10).
**Grounding Instructions.
1. In the event of malfunction or breakdown,
grounding provides a path of least
resistance for electric current to reduce
the risk of electric shock. This grinder is
equipped with an electric cord having an
equipment-grounding conductor and
grounding plug that looks like the plug
illustrated in Figure B. The plug must be
plugged into a matching outlet that looks
like the one in Figure A. This outlet must
be properly installed and grounded in
accordance with all local codes
and ordinances.
2. Do not modify the plug provided.
If it will not fit the outlet, have the proper
outlet installed by a qualified electrician.
Alternatively, a temporary adapter which
looks like the one shown in Figure C can
be use if the wall outlet to be used does
not have a three-prong configuration.
3. Improper connection of the equipmentgrounding conductor can result in a risk
of electric shock. If repair or replacement
of the electric cord or plug is necessary,
do not connect the equipment-grounding
conductor to a live terminal. The conductor
with insulation having an outer surface that
is green, with or without yellow stripes, is
the equipment-grounding conductor.
4. Use only three-wire extension cords
that have three-prong grounding plugs
and three-pole receptacles that accept
the grinder’s plug. Repair or replace
a damaged or worn cord immediately.
See Table 1, page 10 for extension cord
requirements.
5. Check with a qualified electrician if the
grounding instructions are not completely
understood, or if in doubt as the whether
the tool is properly grounded.

OPERATING INSTRUCTIONS
Grinding A Chain
Immediately unplug the
power cord if the motor
does not turn the grind wheel
when the grinder power switch
is in the “on” position. Refer to
page 7: **Grounding Instructions.
1. For best results it is recommended that
the chain be clean before grinding.
2. Always wear approved eye protection
during all steps of the grind operation and
when the grind wheel is in motion.
3. Grind all cutters of the same type (left or
right) before positioning the grinding wheel
to the opposite side.
4. When changing the grind position, make
sure the unit is turned to the “off” position
(“o” Figure 15, page 12) and the wheel
has come to a full stop before making
any adjustments.
5. To avoid overloading the motor and prevent
damage to the saw chain, remove only the
minimum amount of material necessary
and do not grind any one tooth for too
long a period.
6. Do not use cooling liquids while grinding.
7. Replace worn grinding wheels when the
diameter of the wheel reaches 70mm (2.8”).
Note: Always remember to turn the grinder
to the “off” position when not in use.
D. Low-Profile Grinding for
Bench/Wall/Stand Mounted
Workstations:
There is risk of serious
personal injury for chain
