A grinding wheel that has been
improperly installed may crack and
disintegrate during operation resulting
in severe injury to the operator.
A damaged grinding wheel may
disintegrate during use due to high-
speed operation of the unit. This can
cause wheel fragments to eject at very
high rates of speed.
Always maintain 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 a metal tool
like an Allen wrench.) See Fig 4, page 6.
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. We recommend use of Oregon®
grinding wheels only.
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,
remove and inspect the mounting flange
and the grinding wheel.
To avoid possible grinding-wheel failure,
always allow a new grinding wheel to run
at operating speed for at least one minute
before grinding or dressing.
The hazard of kickback resulting in serious
injury to operator is increased if cutting
chain guard drive links or guard tie straps
have been reversed, removed, or filed
down. To avoid injury Do not use a cutting
chain that has been altered in any way.
Cutting chain depth gauges not properly
filed can substantially increase the risk of
kickback and injury. To reduce likelihood
of injury, always file depth gauges to
original profile.
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.
Wear gloves.
Always work cautiously, maintain a strong
grip on the dressing brick, and watch
what you are doing at all times.
Do not use the side of the grinding wheel
for grinding.

INTRODUCTION
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 8).
****GGrroouunnddiinnggIInnssttrruuccttiioonnss..
11..
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 a grounding plug. The plug must be
plugged into a matching outlet that is properly
installed and grounded in accordance with all
local codes and ordinances.
Do not modify the plug provided–if it will not
fit the outlet, have the proper outlet installed
by a qualified electrician.
Improper connection of the equipment-
grounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes is the equipment-
grounding conductor. If repair or replacement
of the electric cord or plug is necessary, do
not connect the equipment-grounding
conductor to a live terminal. Check with a
qualified electrician or service personnel if
the grounding instructions are not com-
pletely understood, or if in doubt as to
whether the tool is properly grounded.
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.
22..Grounded, cord-connected tools intended for
use on a supply circuit having a nominal
rating less than 150 volts:
This grinder is intended for use on a circuit that
has an outlet that looks like the one illustrated
in Figure A. The grinder has a grounding plug
that looks like the plug illustrated in Figure B.
A temporary adapter, which looks like the
adapter shown in Figure C, can be used if
the wall outlet to be used does not have a
three-prong configuration.

55..With an Oregon®flat file (P/N 12211, not
included), file the first depth gauge
(see Figure 18).
66..Remove the gaugit and lower the grinding
wheel so that it touches the portion of the
depth gauge that has just been hand filed
(See Figure 19).
77..Set the depth-adjustment knob and lock
into place. This has just set the depth of
grind for the rest of the depth gauges
(see Figure 20).
88..Turn the power switch to the on position
and grind all depth gauges.

NNoottee::Periodically, it is necessary to refill
the hydraulic system with oil due to static
leakage. The steps for servicing the
hydraulic system are as follows:
1. Raise the grind head to the up/rest position.
2. Unscrew the screw located on the piston
near the vise (see figure 21).
3. Keeping the grind head in the up position,
service the system by pumping clean
hydraulic fluid, with the use of an oil can,
into the piston screw hole until fluid begins
to overflow (see figure 22).
4. Reinstall the service port screw and washer
without tightening the screw.
5. Lower the grind head slowly to bleed off
any trapped air from the system.
6. Securely tighten the service port screw.
