Maintenance
It is important to perform regular maintenance on the
equipment. A daily, bi-weekly, monthly and yearly
schedule should be maintained. Failure to do so
can result in more frequent breakdowns damage to
equipment and/or injury.
Proper Maintenance will help to ensure the reliable opera-
tion of your Raptor. You should allow 5 to 10 minutes for
daily inspection, 30 minute weekly inspection and one
hour monthly inspection. Time invested on these tasks will
minimize downtime. Eastman Machine Company is not li-
able for damage as a result of poor maintenance and any
resulting damage would be repaired at user’s expense. All
maintenance should be performed by qualied personnel,
following all safety procedures. The following is the recom-
mended maintenance schedule:
• At the start of each shift, carefully inspect the
machine and cutting surface. Look for any debris,
loose cables or any other obstruction that may in-
terfere with machine movement or cutting. Vacuum
bristle surface as required to remove dust and dirt
which may clog perforations.
• Check crank and crank bearings for abnormal
wear. Check blade edges for damage and replace
as required. Ensure that the knife is securely fas-
tened to the coupler.
• Power up the Raptor and listen for any abnor-
mal sounds. If abnormal sounds exist, diagnose
and x the problem to prevent serious damage
to the machine.
• After the Raptor is powered up, check both the X
and Y axes for backlash. If the backlash is exces-
sive on either axis, adjust as needed.
Daily Maintenance
• At the end of each work day make sure the
computer is off. Clean-up debris from table and
remove any CD or Disks from the disk drives.
• At the end of the day disconnect power to the
machine.
• Using dry compressed air blow off any loose dust
and debris found on the knife guide assembly and
within the sharpening assembly. Using soft bristle
brush clean all accessible surfaces and knife guide
assemblies. Blow off any loose dust and debris
found after cleaning with bristle brush.
• Using a soft cloth, wipe off the entire machine.
• Check crank bearing for wear. Replace as required.
• Check ball joint for wear or excessive movement.
Replace as needed.

6Form E-564
Eastman

Before performing the bi-weekly tasks make sure
the Raptor and computer are turned off at the
electrical disconnect and locked out.
CAUTION
Bi-Weekly or every 100 hours
• Lubricate Table, Gantry and Tool Head linear
guides with Eastman lubricant 67-26325 (Mobil:
SEA 10 Non-detergent Vactra No. 1) See Lubrica-
tion Chart.
• Lubricate Reciprocating Spline with Eastman lu-
bricant 67-26325 (Mobil: SEA 10 Non-detergent
Vactra No. 1) See Lubrication Chart.
• Remove the tool head cover from the Y-car. Inspect
the cutting head assembly. Look for any wires or
air hoses rubbing or wearing.
• Using compressed air, clean dust and debris from
inside of Y-car.
• Use clean cloth to wipe down Y-axis rails and
lubricate.
• Tighten any loose fasteners on the Y-car.
• Rotate presser foot assembly by hand, it should
rotate freely and be without any play relative to
tool head base plate.
• Check belt deection both in reciprocating drive
belt and theta drive belt. Excessive deection will
need belt adjustment or replacement as needed.
• Check bristle blocks for damage. Replace as
needed.
• Inspect all hardware on gantry, base and take off
conveyor. Secure as required.
• Lubricate Gantry, Y-Car and Tool Head linear
bearings with Eastman lubricant 67-26324 (Mobil:
NLG1 Grade 2 Mobil AW-2) See Lubrication Chart.
• Lubricate Conveyor bearings with Eastman
Lubricant 67-26324 (Mobil: NLG1 Grade 2 Mobil
AW-2).
• Inspect inside conveyor base for loose screws or
abnormal wear. Secure or replace as needed.
Before performing the monthly tasks make sure
the Raptor and computer are turned off at the
electrical disconnect and locked out.
CAUTION
First Working Day of Month
•Remove gantry covers and inspect all electrical
wiring connections for nicks or abrasions. Repair
or replace as needed.
• Inspect all 24 VDC power supply connectors for
any discoloration or signs of heating.
Before performing the yearly tasks make sure the
Raptor and computer are turned off at the electri-
cal disconnect and locked out.
CAUTION
Yearly or every 2000 hours
• Check all belts for signs of wear such as cuts, frays
or missing teeth. Replace if needed.
• Check belt tension. Belt should be tight enough to
prevent backlash between drive pulley and driven
pulley.
• Check for wear on spur gears. Replace as needed.
• Check all shafts and pulleys. Pulleys need to be
seated tightly on the shaft.
• Check all electrical plugs and connectors to ensure
they are securely fastened.
• Check all decals and labels for damage replace
as needed.
• Check and clean air lters. Replace as required.
• Check the take-off belt and take-off drive motor
belt for signs of wear. Replace as needed.
• Check ngers in the bristle conveyor for signs of
wear or damage. Replace as needed.
• Check E-chain and cables for signs of wear.
• Check resealer for signs of wear. Ensure that it is
