Form C-1206
DESCRIPTION
The Buzzaird Rotary Shear has been carefully designed by
the Eastman Machine Company to efficiently cut a variety of
fabrics and provide many years of trouble free service. This
pneumatic cutter is equipped with a heavy duty pneumatic
motor and can be used primarily for heavier types of material
that cannot be cut with our now world-famous Chickadee Ma-
chine. The maximum output is 1/3 horsepower and should
run at 90 psi with a 20,000 rpm motor speed. This machine
should not be run with less than 60 psi.
BALL TIP AND SHEAR PLATE FOOT OPTIONAL*
A ball tip (109C5-1) for cutting loosely woven materials and
shear plate foot (68C3-4) for additional support and cutting
accuracy are optional. To attach shear plate foot to shear plate
(726C1-5) use allen key (95C5-7) as illustrated.
WARNING
Before performing any of the following procedures, make
sure the air line has been disengaged.
TO LUBRICATE
A few drops of 30 weight, non-detergent machine oil twice a
day while operating are all that is required to keep the buzzaird
lubricated. The parts illustration (page 13) clearly indicates
the three recommended lubrication points. To lubricate gears,
remove plug (point C), inject grease once a day. Eastman
Gear Lubricant Special Formula (242C2) is recommended. Be
sure oil felt (191C1-26) is kept clean and moist with oil.
TO REMOVE KNIFE
Remove lock nut (4C1-194) turn counter-clockwise and lift knife
from the gear. When replacing knife (80C1-123) be sure the
knife is installed so that the Eastman name is in the outward
position.

TO REPLACE SHARPENING STONE
Sharpening stone may be replace as required without disas-
sembling cutting head. Remove knife lock nut (4C1-194) and
knife (80C1-123). Remove sharpener button (63C3-21) and
sharpener spring (34C10-131) from rear of sharpener assem-
bly. Sharpening stone and bushing assembly can then be
removed from front of sharpener bracket (636C1-3). Remove
retaining ring (18C6-23) from shaft of sharpening stone
(541C1-22) and remove stone. Note: This procedure is re-
versed when reassembling.
CARE AND MAINTENANCE OF THE MOTOR
An air line oiler and filter should be used for the best perfor-
mance of this pneumatic motor. The motor must be lubri-
cated and free of moisture. If an air line oiler and filter is not
available, a few drops of SAE 5 spindle oil should be used
several times a day in the air input line.
