3.1 Routine Maintenance (All Models)
DISCONNECT POWER before making any adjustments or lubricating.
See page 6, SAFETY PRECAUTIONS, for Power Lockout Procedure.
A clean, lubricated machine will run longer, smoother, cut more accurately, with less downtime and
fewer costly repairs. Schedule lubrication both early in the day and early in the week. This allows the
lubricants to work into the machine. Lubrication at the end of the day or week allows the lubricants to
run off without as much benefit to the machine. The following guidelines will help you set up a regular
maintenance schedule:
3.1.1 Weekly
•Clean — Clean off old, dirty excess grease. Remove the top cover and clean accumulated
dust off knife bar and gib areas. Built-up dust can increase wear to components.
•Hardware — Remove top cover and bottom cover to check all nuts and bolts for tightness.
Loose hardware is the cause of most component wear and in the electrical area could cause
short circuits and/or shock.
•Lubrication — See section 3.3 page 11
3.1.2 Monthly
•Backgauge Squaring — See section 3.5.1 page 13
3.1.3 Yearly
•Knife Bar Gib Adjustment — See section 3.5.3 page 16
•Backgauge Accuracy Adjustment — See Section 3.5.2 page 14
3.2 Cleaning (All Models)
Before cleaning inside machine, turn power off and disconnect power cord.
3.2.1 Table
•The front table should be wiped down periodically. Use a non-abrasive cleaner along with a
protective wax.
•The rear table cover and front shield may be cleaned with glass cleaner or a mild water
based detergent. Some petroleum-based solvents may damage the Plexiglas.
3.2.2 Display Panel
•The display panel should be cleaned with a mild water based detergent applied to a damp
cloth or paper towel. Do not use petroleum-based solvents as they will damage the display.

3.0 Maintenance Guide
11
3.2.3 Machine Exterior
•The machine’s exterior should be cleaned with a non-abrasive water based detergent applied
to a damp cloth.
•Always be careful when cleaning around safety warning labels. Use limited amounts of
cleaners in those areas.
3.3 Lubrication (All Models)
3.3.1 Clamp
Send the clamp down, then turn off the power. Disconnect the power cord, remove and disconnect
the display panel, and remove the top cover. Wipe off any old or excess grease. Use any brand-
name type of grease and apply to the areas shown in Figure 2. It may be helpful to use a small brush
to apply grease.
Figure 2
3.3.2 Backgauge Lead Screw and Guide Shaft
Remove the rear bottom cover. Use any brand-name type of grease or light oil to lubricate
backgauge lead screw and guide shaft (Figure 3, page 12). It may be helpful to use a small brush to
apply grease. Note: the lead screw may be lubricated with grease or oil. Oil has a tendency to run
off and must be lubricated more frequently; grease tends to collect paper dust and must be cleaned
off periodically.

3.5 Adjustments
Some of the following tests require the machine to be operational for
checking and adjusting. Be very careful that tools and other people are clear of moving parts and that
the cutter is not accidentally operated while adjustments are being made. Whenever possible,
disconnect the power and lock it out (see SAFETY PRECAUTIONS, page 6) unless the directions
specifically require the machine to be powered.
3.5.1 Squaring the Backgauge (All Models)
To test if the backgauge is square, place a small lift of paper against the left side of the backgauge
(but not against the side guide) and make a cut. Now, leave the backgauge in the same position, flip
the lift over and push it against the right side of the backgauge (but not against the side guide). Make
another cut to see if any of the paper will trim off (Figure 5). Run two checks, one starting on the left
and moving to the right; the other, moving from the right to the left. If paper is trimmed in either
sequence, the backgauge is out of square.
Figure 5
To square the backgauge:
1. Make sure the backgauge gibs are set properly (see section 3.5.6 , page 18).
2. Remove the rear Plexiglas table cover.
3. Loosen the jam nuts on the backgauge adjusting screws (Figure 6, page 14).

3.0 Maintenance Guide
14
Figure 6
4. Back off the adjusting screw on the side that the trim occurred, then tighten the other screw.
5. Tighten jam nuts and make another test. Continue to adjust and test until no trim occurs
when testing either sequence.
6. Replace the rear Plexiglas table cover.
Note: Once the backgauge is square, check the backgauge accuracy (see Section 3.5.2 below) to
make sure it is accurate.
3.5.2 Backgauge Accuracy Adjustment (Models: SA and A)
If the backgauge position readout does not match the actual measurement between the knife and the
backgauge, the accuracy can be adjusted. The accuracy can be checked by the following procedure:
NOTE: The backgauge should be squared before attempting to adjust the accuracy. (See Section
3.5.1 , page 13).
1. Place a 1/4 to 1/2” lift of 8-1/2 x 11” paper against the center of the backgauge.
2. Using the backgauge position readout, bring the lift up to the 10.00” position and make a cut.
Then move the backgauge up to 5.00” and make another cut.
3. Take a sheet from the center of each lift and compare them to each other. The cutter will
always space accurately between cuts (in this case the 10” and 5” cuts) whether the overall
accuracy is correct of not (Figure 7, page 15). The front stack will be a true 5”, but the paper
left against the backgauge will not be if the backgauge position is inaccurate.

4. The backgauge accuracy can be corrected by adjusting the preset screw attached to the
bottom of the backgauge nut assembly (Figure 8).
Figure 8
Turn off power and disconnect the power cord. Remove the rear bottom cover. Place a
3/16” Allen wrench in the preset screw and hold in position while loosening the jam nut. Now
adjust the screw as follows:
•If rear pile is short (less than 5”), turn screw out (counterclockwise).
•If rear pile is long (more than 5”), turn screw in (clockwise).
1/4 turn = .012” backgauge adjustment
1/3 turn = .016 (1/64”)
1/2 turn = .024”
2/3 turn = .032” (1/32”)
1 turn = .048”
5. Replace bottom cover and turn on power. Note: If power was not off, reset power now or
reading may be false. Bring the backgauge to the front to reset the display and make another
test. Repeat adjustment procedure if necessary.

3.5.3 Backgauge Accuracy Adjustment (Models: AEP)
Refer to the Spartan 185 AEP Operator’s Manual.
3.5.4 Knife Bar Gib Adjustments (All Models)
1. Send the knife to the “down” position by making a cut and when the knife reaches the table,
continue to hold the left cut button while releasing the right cut button and switching off the
power. Then disconnect power cord.
2. Remove and disconnect the display panel, then remove the top cover.
3. Loosen the gib screw jam nuts on all gib screws EXCEPT THE TOP SCREW on each side
(Figure 9).
Figure 9
4. Tighten all gib screws EXCEPT THE TOP SCREW on each side (these should be done when
the knife is up). Tighten so that screws are just snug then add a 1/8 turn. Hold screws in
position with tool then tighten jam nuts.
5. Replace top cover and display panel, plug in power cord, and turn power on. Knife and
clamp will return to “up” position.
6. Disconnect power cord, remove display and top cover, and repeat gib screw adjustment
procedure for the TOP GIB SCREW on each side.
7. Replace top cover and display panel.
3.5.5 Knife Leveling Adjustment (All Models)
If knife cuts through one side of paper and not the other, the knife level may need adjustment. First
check to make sure the knife is installed in the correct position by looking through the viewing holes in
the knife bar (Figure 10, page 17). If the knife is not all the way up on both sides, loosen the knife
screws and use knife lifter assembly to raise knife up tight. Then tighten screws and recheck by
cutting through paper.

If knife is cutting deeper on one side than the other, use the following procedure to adjust:
1. Flip the cut stick to a new position and raise the knife depth by several turns of the knife
adjusting screw (Figure 10).
2. Slightly loosen the left-most knife screw only (but keep somewhat snug).
3. Place a few sheets of paper over the entire cut stick, and make a cut. Adjust the knife depth
and continue to make cuts until the knife begins to cut through the bottom sheet of paper on
either side.
4. Once the knife begins to cut through the bottom sheet on one side, leave the knife down by
holding in the left cut button while releasing the right cut button and turning off power.
5. Disconnect power cord, remove and disconnect the display panel, then remove the top cover.
6. Slightly loosen the remaining (5) knife screws, keeping them somewhat snug.

against it, the backgauge gib screws may be loose or worn.
To Adjust:
1. Turn off the power and disconnect the power cord.
2. Remove rear bottom cover.
3. Loosen the two outside gib screw jam nuts (Figure 12).
Figure 12
4. Tighten the two nylon set screws until they just touch the guide. Do not over-tighten or they
could cause the backgauge to bind. Lock in position with jam nuts. The center screw is a
spring loaded plunger and should not be adjusted.
5. Run the backgauge back and forth the length of the table and check for any binding.
Readjust if necessary. Replace the bottom cover.
3.5.7 Lead Screw Collars (Models: SA and A)
Any play in the backgauge lead screw may cause inaccuracies in backgauge position display.
Excessive play can be eliminated by adjusting the lead screw collars as follows:
1. Turn off the power and disconnect the power cord.
