TDI Hog Equipment Service Technician Course
Course Information
Required Tools List
Pre-requisites
In order to enroll in the TDI Edge/HOG Equipment Service technician course, you must:
· Be at least 18 years old, hold a nitrox diver certification and hold a technical diver certification, or;
· Be at least 18 years old and be employed by a dive shop as a service technician.
If you have any questions about these requirements, please talk to *Joshua before you sign up for the class.
Before Class
It is critical that you read and have a solid understanding of “Scuba Regulator Savvy” by Peter Wolfinger prior to class. The information in this book is critical to understanding and servicing regulators and forms the foundation upon which we will build during the class. Studying is going to take some time: the book is nearly 200 pages long and is densely packed with important information. If you don’t spend the time needed to read and understand the material in the book, you will be cheating yourself and will cause the entire class to get bogged down.
Review the Required Tools list and purchase any items that you don’t already own. Take a few minutes to familiarize yourself with any new acquisitions before the class.
Purchase at least one HOG D1 regulator set. Although much of what you will learn in the class will help you service the other regulators in the Hog and Edge line, including the D2 and the Epic, the D1 is the only regulator that we will be working on during the course. If you have any questions about this, please talk to the instructor before you sign up for the class.
The Day of Class
Please arrive on time. Please call if you are running late so the entire class can prepare a suitable welcome for you while we’re delayed. J
Bring the following items:
· A complete HOG D1 regulator set, including 1st stage, at least one 2nd stage, an SPG and appropriate hoses.
· Copies of your nitrox and technical diver certification cards.
· All of the tools on the Required Tools list.
· A completed copy of the TDI General Liability and Express Assumption of Risk form.
· A completed copy of the TDI Medical Statement form. If you answer “No” to all the questions on the first page, the rest of the form does not need to be completed.
Snacks will be served – usually cold pizza and warm soda. You’re responsible for any other special needs.
Graduation Requirements
You will have successfully completed the course when you are able to clearly demonstrate to the satisfaction of the instructor that you have the ability to independently troubleshoot and service HOG regulators.
Additionally, to successfully complete the course you must:
· Pass the final exam.
· Complete a dive with the HOG equipment that you have serviced and submit a copy of your log for that dive to the instructor. Strongly recommended: jump in a pool, not 150’ of open water.
· Register for the ScubaBoard HOG Repair Station forum at http://www.scubaboard.com/forums/edge-gear/376653-hog-repair-station.html
Required Tools
Many of the following items are available from ScubaTools.com. Where you purchase them is up to you but I’ve found ScubaTools to be good and convenient, if pricey.
Prices and availability are subject to change without notice, if you’re having a hard time acquiring anything on this list, let me know.

· Hook Pin Spanner. Recommended: The Armstrong 34-351 works well – needs to be 1.5” (or adjustable) with a small (1/8”) pin.
· 6” Adjustable wrenches – you’ll need two. Recommended: the Hakuma Tools HT150B 6” Adjustable Bent Nose Thin Wrench are perfect but hard to find. El Cheapos will usually work, especially if you grind them down so that they are no more than ¼” thick. Purists may prefer open face wrenches, however you will need a number of them in a variety of sizes.
· Lighted Magnifier. Recommended: the Tensor Clamp on Magnifier Light Lamp with Outlet. A headlamp with magnifiers works great but a lighted reading magnifier or lighted loupe will work.
· Metric Long Hex Bit Sockets (for torque wrench)
· Metric Hex Key set (including a 7mm key)
· Imperial Hex Key set
Tacoma SCUBA
· HOG D1 1st and 2nd stage regulators with hose, LPI hose, HP hose and SPG.
· Service kits for your first and second stage Hog regulators. You can buy these during the class – most people buy a few extras to take home with them – but remember to bring your credit card.
Not required for the class but recommended for anyone serious about regulator repairs:
· Ultrasonic Cleaner. Empty peanut butter jars and a toothbrush can usually get the job done but if you’re serious about cleaning regulators, THIS is the way to go. Besides, your wife will think you’re a hero and love you long time when you volunteer to clean all her jewelry…
