psi the LED light will flash red. Then after
reinflation, the cap only resets back to a

Check the tyre pressure and inflate to recommended vehicle pressure, before attaching
the alert caps. To help uniformity always check pressure on cold tyres ( ie not driven)
Use your fingers initially to begin to screw the alert caps clockwise onto the valve stem
thread. Once alert cap engaged onto thread place the Hexagon part of the key ( or 15mm ,
6 point socket) over the top section of the alert cap. Continue to twist clockwise with the
key, all the way until firm at the bottom of the valve stem.
Place the Calibration Fork, (end part of the key) into the Calibration Key Groove, on the top
section of the Alert Cap. Twist the top section of the cap approx 2 rotations until firm.
IMPORTANT The alert cap is now calibrated to the current tyre pressure. To verify proper
installation, unscrew the cap with the hexagon key, and it will flash red every 1.5 secs if
calibrated correctly.
Screw the alert cap back on firmly using the hexagon key provided. IMPORTANT A loose
cap could potentially cause a flat tyre so screw on tight to bottom of valve stem thread.
Push on the optional dust cover. This helps protects the cap and also aids the visibility and
brightness of the flashing LED. The alert cap will now monitor your tyre pressure 24/7.
IMPORTANT If the tyre pressure drops 4psi the LED light will flash red. Remove the key and
store it in a safe place. You will need the key to reinflate tyres , recalibrate or change alert
cap batteries.

CONSUMER INFORMATION
Tyrecheckers Alert Cap for Light Vehicles
Tyrecheckers Tyre Pressure Alert Caps simply replace the dustcap on your
tyre valve. The Alert Caps allow you to monitor your tyre pressure by
flashing red when the tyre pressure drops 4psi below the set pressure. This provides
you a clear visual warning that your tyre pressure is now below vehicle specifica-
tions and your tyre needs to be inflated.
Why is correct tyre pressure so important?
Research indicates that consistent correct tyre inflation would:
• Decrease tread wear by 17% (Michelin 2008)
• Increase fuel savings by up to 10%. So $70/week spent on a tank of fuel
equates to up $364 saving per year. ( NRMA Fuel Savings 2008)
• Improve Braking Capacity, Cornering, steering ability
• Improved Stopping and traction of your vehicle adds to general safety.
• Extended tyre life- Under inflation of just 5psi can reduce a tyres tread life by
25% ( Dunlop tyre care)
How do the Tyrecheckers Tyre Pressure Alert Caps work?
The first time you put the Alert Cap onto the valve stem it takes a sample of the tyre
pressure and saves it to a reference chamber. If the tyre pressure drops 4psi from the
original pressure the LED light will start flashing every 1.5 seconds until the tyre pres-
sure returns to original pressure setting.
Technical Specifications
1. The Alert Cap is designed to withstand the toughest of conditions, with the
casing made of stainless steel, threads of brass and a polycarbonate lens.
The Alert Cap is vibration, shock, and “road chemical” resistant.
2. The Alert Cap is so small (25mm X 15mm) and light (15g) it will have little or
no impact on the wheel balancing and is totally water proof and airtight.
3. The battery is made from alkaline manganese which is a non hazardous sub-
stance and therefore doesn’t pose environmental or hazardous waste disposal
problems.
4. The Alert Cap can handle pressure spikes 200 psi above calibration pressure
and will operate effectively within -40C - +100C temperature range.
5. The Alert Cap has an accuracy of +/- 1psi
Battery Life
The battery life has approximately 4 years in stand by mode (with correct tyre pres-
sure) or 6 to 7 weeks of continuous flashing (with under inflated tyres). If on inspec-
tion the flash becomes dim, the fully integrated batteries can be changed with 2x
G10 button batteries. Each battery is Alkaline Manganese 1.5V, 11mm Diameter and
3.1mm High. Battery Replacements are available direct from
www.tyrecheckers.com.au website.
Applications and Suitability
The Alert Cap fits all tyres with standard valve stems and is suitable for light vehicles
with a tyre pressure between 10-70psi.
To Recalibrate the Alert Cap
Take the cap off the valve stem. Hold the bottom of the cap using a 15mm 6point
socket ( or 2nd key). Using the calibration fork end of the key, twist the calibration top
section of the alert cap about 2 turns anti-clockwise. Then using the hex part of key
screw the cap onto any tyre with some pressure in it. This will reset the calibration
back to Zero. Then unscrew the cap off again and re-calibrate according to steps 1 to
6 in the instructions.
To change the Batteries
Take the cap off the valve stem. Hold the bottom of the cap using a 15mm 6point
socket ( or 2nd key). Using the hex part of the key unscrew the top section of the
alert cap anticlockwise until it comes off. Carefully take out the 2 batteries and replace
with both batteries Positive sides facing down, to the bottom of the cap, on top of the
spring. Assemble the top of the cap again in reverse order.
General Precautions
1. We recommend you periodically check the battery by taking the Alert Cap off to
ensure the LED light flashes. A dimming of the flash will indicate a declining
battery and the unit should have batteries replaced.
2. If you run different front and rear tyre pressures, be sure the caps always remain
in their original front/rear positions, since they are calibrated accordingly. To as-
sist you with this you can with a sharp object scratch off the letter “F”(front) or
“R”(rear) under the Alert Cap to ensure that it will be reattached to the right axle.
3. If using Alert Caps in conjunction with valve extensions please make sure that the
extensions are designed to constantly be pressurized and that there are no leaks
in the joints. We also recommend that you calibrate the Alert Caps on the tyre
without the extension before putting them onto the extension. The reasoning is
that the additional spring load for the valve of the extensions may interfere with
the calibration process.
4. After fitting the Alert Caps, it is advised to check adequate clearance exists with
other mechanical componentry e.g. e.g. brake callipers, bike frames, and that
the Alert Caps do not stick out further than the side of the tyre.. If they do, please
have a shorter valve stem installed.
5. As batteries are replaceable, Alert Caps can be used on spare tyres or tyres
in storage. You can save battery life by taking batteries out or simply un-cali-
brate the Alert cap. This is done by using the fork end of key and twist the top,
approx 2 full turns in a counter-clockwise direction.
6. No need for a wheel balance but we recommend when you have your tyres bal-
anced, to keep the caps on to include them in the weight.
Warranty
The Alert Cap comes with a 2 year Manufacturer Warranty. If found defective, return
to the address on the website with a copy of the purchase receipt. We will examine
the unit and replace or reimburse, if found faulty under the warranty.
Batteries are excluded from the warranty and as such we would recommend initially
replacing the alert cap with new batteries to address any concerns.
Liability
The Alert Caps are only an aid in monitoring low tyre pressure. The Alert Caps do not
relieve you from your obligations of regularly checking your tyre pressure. We limit
our maximum liability to the purchase price of this product.
