DESCRIPTION


TRAILHEAD Automatic Tire Deflators will automatically reduce the air pressure in a tire to a predetermined level and stop, preventing any further loss of air from the tire. They will function properly whether your vehicle is stationary or traveling at speeds of 20 mph or less. The shut off pressure on your tires may vary due to several factors, especially the flow rate of your valve stems.

 


ADJUSTMENT INSTRUCTIONS

 

1. Turn adjusting screw with a 5/32” allen wrench counter clockwise until it is even with the end of the body tube. This will set pressure at the lowest end of the adjustment range. Every complete turn clockwise will increase pressure approximately 1.5psi for the 5-20psi
range, and 3psi for the 15-40psi range.

 


2. Turn the adjustment screw clockwise the desired number of turns and follow “OPERATING INSTRUCTIONS”.

 


3. If tires have not deflated to the proper value, make minor adjustments to the adjustment screw, re-inflate and re-test. Some experimentation may be necessary to find the exact setpoint. This process goes quickly if a small spare tire  (i.e. wheel barrel tire, ATV tire, etc.)is for use during the adjustment process. This process should take about 15 minutes as opposed to over an hour using a full size off road tire.


 

OPERATING INSTRUCTIONS

NOTE: In order for deflators to reliably begin operation, tires must be inflated to a pressure approximately twice the setpoint, e.g.: If the deflators are set to shut off at
10 psi, tires must be inflated to approximately 20 psi or greater.

 

1. Remove valve caps and replace with one tire deflator on each tire.


2. Wait until deflators are finished deflating and remove them from the valve stems.


3. Check pressure and make any adjustments to tire pressure or deflators setpoint as necessary.

 

A WORD ABOUT ACCURACY: Consistency is more important than accuracy. Usually it is more important to have both tires on a given axle deflated to the same pressure than to be exactly at the setpoint. Be sure to make every measurement the same way, every time. Consistency and repeatability are greatly improved when the valves on all four tires are from the same manufacturer and lot. This will minimize differences in the rate of flow from tire to tire that cause inconsistent readings.


 

CLEANING INSTRUCTIONS


1. Remove adjustment screw & spring while noting the number of turns the adjustment screw was inserted. Remove ball valve by blowing air into the knurled end of the deflator. Keep one hand over the open end to catch the ball and prevent loss. Make every effort to keep the components of each deflator together for
reassembly later.

 

2. Thoroughly clean inside the deflator’s bore with a Q-tip and rubbing alcohol, then compressed air. Clean all components with
rubbing alcohol and compressed air.

 

3. Apply a fine coating of a high quality, heavy silicone or teflongrease or Vaseline, or a similar lubricant to each ball valve.


4. Insert the stem of the ball valve into one end of the spring and slide this assembly into the deflator, ball end first.

 

5. Install adjustment screw (the same number of turns before it was disassembled).



CAUTION: The greatest care has been taken during manufacturing to insure a quality product. However, if the deflators become dirty internally, they may leak and never completely shut off. They will then need to be cleaned. We recommend the use of quality valve caps at all times when not deflating to help prevent contamination of deflators from dirty valve stems, and that the deflators not be installed on your tire for more than 60 minutes. 

LIMITED LIFETIME WARRANTY: This product is warranted against defects in workmanship or materials for the life of this product. This warranty does not apply to damage due to misuse, loss, or lack of maintenance. Product must be returned to us with transportation charges prepaid and a description of the defect. We will repair or replace any deflator that is defective, and return at our expense.

WARNING!!! Use EXTREME CAUTION when driving with partially deflated tires (any pressure other than the manufacturer’s recommended pressure) whether on or off pavement. If you are traveling too fast while turning with partially deflated tires you may pull a tire’s seal off of it’s wheel. You will instantly lose all the air in that tire, which may result in your vehicle rolling over or going out of control, causing DEATH, BODILY INJURY AND/OR PROPERTY DAMAGE. The dangers of traveling with partially deflated tires are NOT LIMITED TO THIS EXAMPLE!

You are completely responsible for your own safety and the safety of those with you. JD Enterprises and Low Range Off Road will not be responsible and will not assume any liability for incidental damage, injury or inconvenience to property or persons (including flat tires) as a result of use or misuse of this product.
