Merrow Factory Service FAQ

We've fielded a number of questions about the Merrow Factory Service Program - here are some of the more common one with answers. Have another question? CLICK HERE

Q: How old is my sewing machine
A: We're glad you asked. How Old is your Merrow?

Q: This is a great program, but I have 40 machines can you come here to service them? 
A: We'd love to, but no. What we can do is set up a dedicated service window for your equipment and have some percentage of the machines (say 10 at a time) come in on a palette and be turned around together and quickly.

Q: I need it returned FASTER than 5-7 days....
A: We can help. we have an expedited program, just call us and let us know how quickly everything needs to get done.

Q: Do you replace the gaskets? 
A: We replace any beat-up gaskets that need to be replaced. almost all the gaskets are replaced as part of the $299 program, however there are one or two exceptions

Q: I really like my local mechanic, why are you taking business from him?
A: We also really like your local mechanic. and if he can take care of your Merrow then PLEASE send it to him/her. We're offering this service for all of the Merrow customers who don't have a local mechanic anymore, but want to keep their machines in tip-top shape

Q: Can I send in a non-Merrow Sewing Machine (juki, union special etc...)
A: No. The $299 program is only applicable to Merrow Sewing Machines.

Q: Is this an international program
A: Not right now. Plans for rolling it out in the UK, India, Brazil, Mexico are underway however. If you'd like to be a Factory Service Provider let us know -- if you are in some part of the world that needs service, also let us know.

Q: For $299, what do I get 'free'
A: Obviously having paid $299 nothing is free... however for $299 you get the following
          1. shipping (3 ways) :: box to you ---> machine back to us ----> machine back to you
          2. Upper & lower loopers
          3. Upper & lower cutters
          4. Needle(s)
          5. LABOR!

Q: What happens if the service is more than $299?  
A: If you send in a machine and we can't service it without a serious re-work, we'll call you and let you know what the additional charges are. Keep in mind we WILL NOT charge for additional labor, just parts. OR:

1. We will offer you a credit for the machine if you purchase a new one. The credit averages $600 (not bad if you bought the machine for $50 ....)

2. We will ship it back to you and charge you just for the cost of freight (usually around $50)

Q: is this only for broken machines?
A: No. The program is great for machines that need to be cleaned, tuned, re-oiled, or have general maintenance done. This program does this especially well.

PLEASE EMAIL with more questions. As we get them we'll post the answers to the FAQ. 

RIVITEX COMERCIO: Expanding the Merrow Market in Brazil

Rivitex Comercio is a leading parts and equipment supplier to the Brazilian textile industry and a premier Merrow sales agent. Rivitex specializes in overlock sewing and since 1995 has sold and serviced Merrow end-to-end seaming machines used in the textile finishing sector. Recently, Rivitex expanded their presence in Brazil's burgeoning apparel industry and successfully introduced Merrow ActiveSeam. The formula for Rivitex's success was simple:

 1. Visit the Merrow Factory for ActiveSeam sales and service training.
 2. Work with Merrow marketing to develop assets for local advertisement.

 On the heels of a successful showing at the Febratex trade show in Brazil this past August, Thomas Schwarzbach from Rivitex came to Fall River to learn the ins and outs of the MB-4DFO and he brought examples of the advertising materials he made for the Brazilian market. Take a look below for some pictures from Febratex and Thomas' time at Merrow!

You can learn more about Rivitex on their website and Facebook page.

New guy needs a hand

I am relatively new to the embroidering field but have been getting calls for patches now and then. I currently limit my patches to felt or similar material because it does not fray.

I recently purchased an old A3DW3 machine that, like most old merrow's, runs like a top. I hope to use it until I win the Lotto and can afford an MG-3U.

I personally like a Merrow stitch at the edge and am working towards that.

Question #1 is: How close can I get with the A3… Continue

Launching the site

Today we did the last of the heavy lifting on the community site. Hopefully all will enjoy.

I have been surfing the world wide web and seen a lot of buzz surrounding the 18-E. For a regular crocheter like myself, I can't help but get excited about the possibility of Merrow going into production for this much anticipated release.

It is my hope that it will be released this fall so I can start my blanket business(finally! lol). I already have 5 orders for my football themed Eagles blanket, not to mention getting a head start on my homespun christmas gifts for friends, family… Continue

m-2dnr-1 won't chain off

How do I get my m-2dnr-1 to chain off? When I stitch off the fabric the stitches immediately stop locking and start to unravel for about 1 1/2 inches. Any suggestions are appreciated.See More

Changing the feed cams on a MB-4DFO

I was wondering if anyone here has ever had to change the feed eccentrics on the active seam machine? I am currently running a 6-82-28 with a 6-82-32. When I sew stretch fleece, the seam comes out very wavy and doesn't lay flat. I am thinking I need to run two 6-82-32 to have the feed take up evenly without the stretch. Can anyone offer their opinion on what I am thinking or how difficult it may be to take on the task of changing these eccentrics out myself?Thanks See More

Missing Loops

Hello Everyone,    I am the proud new owner of an MG3U for my embroidery business. It seemed to sew perfectly in the store, but since I have the machine home, I am having issues. I think I have the tensions set right, but it continues to miss loops of the cover thread.20130830_065416.jpg…See More
