WORKPIECE AND WORK
AREA SET UP
GENERAL OPERATING
INSTRUCTIONS
1. Designate a work area that is clean
and well-lit. The work area must
not allow access by children or pets
to prevent distraction and injury.
2. Route the power cord along a safe
route to reach the work area without
creating a tripping hazard or exposing
the power cord to possible damage.
b. Tap the flat side of the wheel with
a light non-metallic object, such
as a screwdriver handle, at a point
45° from the vertical center line on
each side of the wheel and 1 – 2
inches from the edge of the wheel
(see illustration).
c. Rotate the wheel 90° and repeat
the test until the entire wheel has
been checked.
d. An undamaged wheel will give a
clear tone. If cracked, there will
be a dead sound and not a clear
ring.
5. Place the Grinding Wheel on the
Arbor, then thread the Outer
Flange onto the Spindle. Wrench
tighten only enough so that the
wheel is securely held on thespindle.
6. Replace the Grinding Wheel Cover.
The power cord must reach the
work area with enough extra length
to allow free movement while working.
3. There must not be objects, such as
utility lines, nearby that will present
a hazard while working.
4. You must use personal safety
equipment including, but not limited
to, ANSI-approved eye protection.
Wear heavy-duty gloves when
handling the saw chain.
5. Before beginning work, provide for
sparks and debris that will fly off
the work surface.
1. Unplug the Sharpener.
2. Refer to the saw chain’s instructions
to determine the sharpening angle.
3. With the angled cutting edges
facing right, place the saw chain
in the Vise, engaging the chain on
the spokes of the Chain Wheels.
4. Squeeze the Vise Handle to test
clamping tension. Adjust the Clamp
Lock Nut until the saw chain does
not move while being clamped.
5. Sharpening the right-hand cutters:
a. Loosen the Angle Adjustment Knob,
align the Angle Arrow to the correct
angle to the left of 0 on the Miter
Gauge, then tighten the Angle
Adjustment Knob. See Figure E.
b. Turn the Chain Roller until the first
right-hand cutter is in position. Then,
engage the Chain Stop to keep saw
chain from moving.
4. Closely inspect the wheel before
mounting. Perform a ring-test on
the wheel (unless wheel is smaller
than 4″ or is an unusual shape)
as follows:
a. Suspend wheel using a dowel or
finger through the arbor hole.
