  • Our PDF manuals are accessible with all versions of Windows, iOS, Mac, and other digital devices, making them great for any device user. Enjoy enhanced compatibility and get the information you need, whenever you need it.

When will I receive my manual after I buy it?

After purchase, your manual will be emailed to the address you supplied usually within about 1 hour. Just to be safe, we have listed the processing time as 8 hours. You will never have to wait longer than this.

Can I find these manuals online for free?
Some sites may offer much lower-quality manuals for no charge. These sites may contain malicious files that can do damage to your computer. And most of the time, end up not even having the manual they claim to have.

How large are the files and how will the download work?

The PDF files vary from 5MB to a maximum of about 1000 MB. The email you receive will contain a link that will redirect you to a file sharing called Send-space. This link will automatically start the download for your desired manual.

How will I open the PDF manual?

All of our manuals are PDF files that will open with Adobe Reader. 95% of computers come with this program already installed. If your computer does not have this software, it can be downloaded for free at: http://get.adobe.com/reader/

Can I have the manual shipped to me?

Digital download directly by a link provided by us.

Can I have the repair manual printed out and sent to me?

We apologize but we only offer digital manuals. Upon receiving the manual you may print out the entire thing or only your desired pages.

How can I pay for the service manual?

We accept all major brands of credit and debit cards. We also accept PayPal as a method of payment.

How will I be able to browse through the manual?

Almost all of our manuals contain a very easy-to-follow index. In the case that you have purchased a manual without an index, all manuals are fully searchable. This means that holding Ctrl and pressing “F” will open a search function in Adobe Reader, you can then search the entire manual for any specified word or phrase.

Are your service manuals printed by the manufacturer of the vehicle or by an aftermarket company like Clymer or Haynes?

Our manuals are all OEM factory service manuals; they have been written and printed by the original manufacturer of the vehicle itself.

Is the manual mine forever?

Yes, once you have received the email with the link, do not delete it. This file will be downloadable as many times as you like with no time limit. We recommend that after opening, you save the file somewhere on your computer you will remember.
