Lubrication

Any tools or supplies needed for these procedures are provided in your operator's kit.

Using the correct lubricants properly and when specified by scheduled maintenance is critical to the operation of the AMAYA. Failure to use the proper lubricants as specified can shorten the usable life span of internal components and can void the warranty. Using the wrong lubricants can adversely affect your machine. The recommended and authorized lubricants to be used on the AMAYA are specified below:

Melco Part Number:	Part Name	Comments
761003-01	Oiler, 3/4 oz. bottle	sewing machine oil
32078	Grease, EMB-Polymer, 8 oz bottle	polymer light grease
32079	Grease, Multi-purpose (Lithium), 8 oz bottle	heavy grease

Maintenance Schedule

The following table summarizes the lubrication points and schedule for your machine. The table also lists which type of lubrication you should use for each lubrication point.

Please note that these schedules are meant to be used as guidelines. Depending on many circumstances (such as environment, garment types sewn on, etc.), you may need to lubricate your machines more or less frequently. Follow a lubrication schedule that best fits your needs to take care of your machine(s).

WARNING! Do not attempt to lubricate the machine while it is in operation.

Important: The color change lead screw is greased for life and should NEVER be lubricated by the user or a technician.

Once a Year

The following belts should be checked once a year: X-Cable, Y-Axis Timing Belt, and Z-Drive Belt. You can either have a Melco Service Technician check these belts for a charge (contact Melco Service-303.457.2025), or you can perform these checks yourself. To perform these checks, you will need to purchase the following tools / fixtures from the Melco Parts Department (800.877.4272), and follow the procedures in the AMAYA Technical Manual.

Fixture, Y-Belt Tensioning (PN: 32108)
Force Gauge (0-10 lbs.) (PN: 995591-01)
Universal Force Gauge Adapter (PN: 32498)

See the AMAYA Technical Manual, see , ,

CAUTION! Some of the lubrication procedures instruct you to remove the right/left front covers. Do not turn the AMAYA machine off, then on again when either of these covers is removed. This will cause the machine to color change, which will cause the needle bars to fall out. Do not move the needlecase at all when either of the front covers is removed. If you proceed without this cover damage to your machine will occur and a service call will be necessary.

Disclaimer: Melco will not be held responsible for any damage to the machine from not performing this step.

Maintenance Timers

As long as you have maintenance timers enabled (see Timers Tab), you will be guided through the lubrication of your machine with maintenance timers (see example below).

Each time a maintenance timer reaches zero, a dialog box pops up indicating that you need to perform that maintenance. To perform the maintenance, click the Step button. You will then be guided through performing the maintenance step by step. (These step-by-step procedures are condensed versions of the lubrication procedures in this section; these step-by-step procedures also perform the machine commands, such as head up, for you.) If you successfully complete the maintenance, the timer will reset when you are finished. If you receive an error while you are performing the maintenance that prevents you from successfully completing the procedures, the timer will not reset. You will need to restart the step by step procedure and complete it successfully.

If you click the Reset button, the stitch count for that timer will be reset to zero. However, it is strongly recommended that you do not reset timers without performing the required maintenance. Neglecting the maintenance of your machine could damage your machine. You can click the View All button to display all of the maintenance timers (displayed on the Timers Tab). If you click the Ignore button, the dialog box will be displayed again after each successive design is completed.

You can perform the step through procedures at any time for any timer interval. To do this, open the Settings menu and click the Timers tab. Click the Step button for the timer interval to step through the lubrication for that interval. If you successfully complete the maintenance, the timer will reset when you are finished. You can click on any of the pictures in the step through procedures and they will enlarge.

You can perform the step-through procedures provided by the timers without using the procedures below (unless you want to refer to the pictures). If for some reason you are lubricating without using the step-through procedures, follow the procedures below.

Maintenance Procedures- 200,000 Stitches

Rotary Hook

Follow these steps for rotary hook lubrication:

Remove the bobbin case from the hook assembly.
Clean the rotary hook area with a brush (or canned or compressed air). While the bobbin case is out of the machine, you may want to clean it as well (click here for instructions).

NOTE: Excessive thread or lint buildup may require removal of the hook guard.

Select the Maintenance menu in AMAYA OS.
Click on the Head Timing tab.
If performing maintenance on all machines in a cluster, check the All Machines box. If performing maintenance on a single machine in a cluster, uncheck the All Machines box, and click the machine in the Machine List.
Click the Oil Hook button.
Place one drop of sewing machine oil in the rotary hook as shown in the image below. Be careful not to over oil. USE MELCO OIL WHEN OILING.

If you do squeeze too much oil, then you may need to run a sewout on some scrap fabric. This will prevent the excess oil from getting all over your garment.
Click the Spin Hook button in the Head Timing tab and the hook rotates for several seconds to spread the oil.
Replace the bobbin case in the machine, and thread the needle if required.

Thread Feeder Roller Inspection, Cleaning, and Lubrication

For this maintenance procedure, you will need to inspect each thread feeder roller. Repeat the following procedure for each roller:

(This section provides part numbers for the parts you may need to replace. Please note that it is possible for part numbers to change after the release of this help system).

See the Thread Feeder Roller Troubleshooting section for more in-depth information about thread feeder rollers.

Lift the thread feeder lever.
Remove the thread feeder front cover, carefully using your fingernails or a screwdriver.
Using two thin-bladed flat screwdrivers, carefully pry the thread feed roller out of the assembly.
Rotate the roller, inspecting it for wear, nicks, or grooves. Also check the roller for dust, lint, oil, or grease accumulation.
Using a clean, dry cloth thoroughly clean the entire surface of the thread feed roller. NOTE: A small amount of alcohol may be used on the cloth if oil or grease need to be removed.
Using the photograph as a guide, thinly grease the hubs on each side of the thread feed wheel with a flat-blade screwdriver or a cotton swab.
To re-install the thread wheel, align the wheel in place as shown in the photograph and push it all the way in until it snaps.
To re-install the cover, move the thread out of the way. Insert the top of the cover into the slot at the top of the thread feeder assembly. Push it until it snaps into place.
Rethread the machine if necessary. Make sure the thread is centered in the grooves on the thread feeder front cover as shown in the photograph. When you are finished, lower the thread feed arm.
Visually inspect each red pinch roller. If you detect a line in the center of any of the pinch rollers, run a fingernail across each of these rollers to check for grooves as shown in the photograph. Please note that lines on the surface of the rollers are normal, but deep grooves can affect the operation of the thread feed system.
If you detect a groove in a roller and the thread fits into the groove such that the top of the thread is lower than the surface of the roller then the roller needs to be replaced (Melco P/N 30619-01). The picture shows a front view of a grooved pinch roller that needs to be replaced.
While slightly lowering the thread feeder arm with one hand, use the other hand to remove the red pinch roller as shown in the photograph.
Using a clean cloth, lightly covered with alcohol, clean all the old grease and residue from the thread feeder arm.
Using the photograph as a guide, apply a small amount of EMB polymer grease to the surface of the thread feeder arm.
Snap the red pinch roller wheel back onto the pinch roller arm. Check to make sure that there is no grease on the surface of the pinch roller or the thread feed roller below.

Reinstall the right upper arm front cover.

Maintenance Procedures - 50,000,000 Stitches

Y Drive - Bearing Block Assembly

CAUTION: DO NOT APPLY GREASE TO THE Y-RAILS. If you do so, machine performance will be impaired. Grease will attract dust, which will serve as an abrasive against the bearings and the shaft.

If you follow the procedure as described below, it is not necessary to remove the machine’s red transparent covers. If desired, the red covers can be removed to make the oiling holes easier to access.

Move the x-carriage to the center of the y-rails.
Remove the side covers of the machine
Use the image below to locate the oiling hole on the top center of each bearing block assembly.
Position the side cover in its original location on the machine as shown in the photograph. Loosely install one of rear mounting screws to maintain the cover position. Install the other cover screws with the long screw in the front cover location before final tightening the three screws. Tighten the screws only enough to secure the cover as over tightening may cause cosmetic damage to the cover. When you are finished click on OK and the Needle Case will advance to needle number 16.
As shown in the image above, add 100 drops of sewing machine oil to the oiling hole. Repeat for the oiling hole on the other side of the machine.
