This machine is equipped with a sharp knife.
Keep hands away from the knife area at all
times. Use control levers and handles only
when operating or handling machine. When
machine is not in operation the KNIFE
GUARD/PRESSURE FOOT should be kept
lowered (by depressing lever B) to the base
plate at all times, except when changing
the knife or performing similar maintenance.
When making a cut the KNIFE GUARD/
PRESSURE FOOT should be raised by
handle G only enough to clear the material
being cut. When this equipment is not be-
ing utilized, the power supply should be
disconnected from the machine.
WARNING:
The purchaser must instruct all operators on the proper use of
the equipment. All standard industrial safety measures and
equipment should be provided to protect the operator. Opera-
tors must be cautioned that improper use of this equipment can
cause bodily injury. If you do not have qualied operators to
instruct new persons, contact your Eastman sales representative
or write to Eastman Machine factory direct.
Before starting the motor, be sure that electric supply voltage
and current are the same as stamped on the nameplate.
Fill oil cup F (see illustration page 3). Make sure the sharpener is
in locked position. Push in turning knob A and turn the machine
over a few revolutions by hand to see if the knife moves easily.
If the knife does not move easily, sharpener is probably in an
unlocked position. Use bell crank release lever N to return
sharpener to locked position.
Proceed as follows: Check to see that motor switch is in off
position. Connect attachment plug to terminal block on machine.
With left hand straddle front of sharpener with ngers and
thumb. Press in release lever N to dis-engage sharpener
mechanism from motor. With right hand turn on motor switch,
allow motor to gather full speed and then release lever N. This
will automatically return sharpener to locked position. Knife
must be in machine.
The variable speed straight knife ranges in speeds of 1,200 to
4,000 RPM depending on the control setting. The setting, de-
pending on operator preference, can be decreased by turning
the speed control knob "1" counter-clockwise to a lower number
(0=1,200 rpm) or increase by turning clockwise to a higher number
(10=4,000 rpm).
For the rst week or two, or after the machine has been idle for
any length of time, the motor should be turned on and off a few
times before running continuously. This permits the oil to warm
up and ow easily into the closely t moving parts. IN COLD
WEATHER, PLEASE KEEP MACHINE IN WARM PLACE.
Before performing any of the following
procedures, make sure that the attach-
ment plug has been disconnected from
power source.

nuts Q and remove sharpener.
Do not use sewing machine oil or
detergent oil. It is entirely too light for
cutting machine lubrication. For best
results use specially compounded
Eastman 30 weight non-detergent oil.
Do not oil Base Plate Rollers.
This machine is designed for hand held operation only. East-
man Machine Company does not approve of the use of its
machine when employed as part of another machine. Nor does
the company assume any responsibility should the machine be
modied without prior factory approval or used in such a manner
that the operator does not have continuous control over the
cutting machine.
CARE OF MACHINE
Use air hose or bellows with proper eye shields and blow lint
our of motor and sharpener twice a week. Remove cover O
and clean out lint around screw mechanism in sharpener once
a week. Remove knife and clean knife slides with slot cleaner
at least once a day. To prevent undue accumulation of lint, do
not oil plate rollers. If rollers stick, remove from plate and
wash in cleaning solvent.
TO SHARPEN THE KNIFE
Take the machine out of the lay. Drop KNIFE GUARD/PRES-
SURE FOOT by means of pressure foot lever B located next
to machine operating handle. Press lever K downward with
a slow, rm pressure to engage sharpening mechanism. Too
fast lever action may cause lever to lock. If this occurs, lift le-
ver M and start over. After a few tries you will feel correct
operating pressure.

Replacing the Rubber Driver Pulley
The sharpener is driven by a rubber driver pulley, as shown
in Figure 2. Replace this driver pulley whenever it appears
to be worn or damaged, as follows:
1. Remove the sharpener from the machine (see Remov-
ing the Sharpener on page 3).
2. Press the sharpener lever (Page 3, Figure 1, K) to a
neutral position and lower the sharpener until an inch
of the square shaft (Figure 2, W) is exposed.
3. Hold the square shaft with a wrench. Position the
wrench as close as possible on the shaft to the sharp-
ener housing.
4. Use a spanner wrench to remove the driver pulley
by turning it clockwise as indicated by the arrow in
Figure 2.
Note: The pulley has a left-hand thread.
5. Reassemble the new pulley on the sharpener.
6. Reassemble the sharpener on the machine.
Motor Brush Replacement
Remove (2) screws A from brush cover B. Remove brush
cover and gasket. Remove (4) screws C from speed
control cover. Carefully move aside speed control cover
and gasket. Movement of parts will be restricted by wires
but have adequate length to work without disconnecting.
Loosen screw E and remove the motor brush terminal
(only) from under the fastener. Remove brush retainer F
by pushing in and forward to release and remove. Slide
brush and pressure spring out of guides.
Before inserting new brushes, use air hose or bellows with
proper eye protection and blow lint and dust out of
motor. When inserting new brushes, brush wire must
face slot G in brush holder. Place brush terminal under
fastener E and secure. Place pressure spring in brush
guide with spring unwinding toward center of motor. In-
sert brush retainer. Secure retainer hooks in guide slots.

Belt Sharpener
Adjustment Instructions
Before performing any of the following
procedures, make sure that the attach-
ment plug has been disconnected from
power source.
TO CHANGE SHARPENER BELTS
Push brackets C inward to release tension and remove worn
belts. Place new belt over front pulley S, then between sharp-
ener shoe T and knife and then over rear pulley U. Sharpener
belts are available in 4 grits: Rough, Coarse, Medium and Fine.
(See page 8).
ADJUST STABILIZERS FOR CENTRAL ALIGNMENT
Disengage attachment plug. Depress sharpener lever (K) half-
way and lower belt carrier to extreme bottom position. (See page
3) Loosen screws (1) and disengage back guide (6) from contact
with standard. Loosen screws (2) and disengage stabilizers (4)
and (5). Remove locknut (3). Install Gauge
#C-189 on exposed threaded end of pivot screw (7) and press
end of gauge against side of standard. Hold this position, engage
opposite Stabilizer (4) rmly against side of standard and tighten
screws (2). Remove tool #C-189, press positioned stabilizer (4)
against side of standard, fasten opposite stabilizer (5) rmly
against standard. Replace locknut (7). Reengage back guide
(6) in loose contact with back of standard.
CHECK SHARPENER SHOES AND CLAMPING ARM
Shoes should swing in and out freely without excessive up and
down play. If adjustment is necessary, loosen locknuts (3),
tighten screws (7) as required.
Check Clamping Arm (10) with the belt carrier in the most
downward position and the knife in the most upward position.
Clamping Arm should hold shoe from moving in. If it fails to do
so, serrations on clamping arm are worn or shoe (11) is worn.
Parts should be replaced.
CHECK EXTREME
DOWN POSITION OF SHARPENER
Correct down position is having the tip of the knife at the
center of the belt on shoe (12) when the belt carrier is in the
most downward position and the knife is in the most upward
position. If the belts are too high, the bottom point of the knife
will not sharpen, if the belts are too low, the bottom point of the
knife will round off excessively.
If adjustment is necessary, raise belt carrier to up position.
Remove plastic cap from tube for screw shaft. Use pin through
hole in tube (13) to prevent spacer (14) from turning, remove
locknut (15). Turn spacer clockwise with wrench #C-6153 to
raise bottom position and counter clockwise to lower position.
One turn adjusts 1/32". When spacer is adjusted use pin to
hold spacer in position, re-assemble and tighten locknut (15).
Replace plastic cap.
CHECK STOP SCREW (8) ON SHARPENER SHOE
With new belts on carrier, insert .010 feeler gauge #141C1-27
between stop screw and knife and be sure that clamping arm
(10) has been released from Sharpener shoe (11). The gauge
should just ll space between screw and knife. If adjustment
is necessary, loosen locknut (9) adjust set screw to proper spac-
ing and retighten locknut.
CHECK WIDTH OF BEVEL ON KNIFE
Bevel should be approximately 1/16" on both sides. Install new
knife and new belts. Color bevel with wax pencil. Run sharpener
up and down several times. If adjustment is required: for Flex-
Pad shoes insert Tool #C-6226 over the belt guide pad and move
free end of tool to the rear to increase the bevel, to the front to
decrease the bevel.
