X’TREME DUTY ONBOARD AIR SYSTEM
TIRE INFLATION GUN OPERATING INSTRUCTIONS
(USE CONTENTS OF PARTS PACKAGE #7)
Your Onboard Air System also comes with a Tire Inflation gun for airing up tires, and adding compressed air
to any inflatable item with a valve stem. The Tire Inflation Gun has a normally closed lever style air chuck at
the end of its rubber hose. After connection to an air source such as an air tank via the quick connect stud
preinstalled in the unit, air may be discharged from the gun by simply squeezing the inflation trigger.
To check air pressure, simply release the trigger and check the onboard air pressure gauge.
1. Using the Tire Inflation Gun:
Using a 1/4“ Quick Coupler, connect the Tire Inflation Gun to an air hose and connect to a tire valve stem or
similar inflation collar by securing the folding lever on the Inflation Gun air chuck.
2. Filling Tires and other Inflatable Items:
Squeeze the Inflation Trigger on the Inflation Gun by pressing it towards the handle of the gun. This will allow
stored air from the air tank to flow through the gun and through the chuck into your tire or other inflatable.
3. Checking Tire Pressure:
To check tire pressure, release Inflation Trigger on Inflation Gun and allow the needle of the 0-200 PSI gauge
to settle. Tire pressure will be able to be read only when the inflation trigger is released.
WARNING:
- Never operate the Inflation Gun at any pressure exceeding 150 PSI.
- Use caution when attached or removing air chuck from valve stems.
- Always ensure that tire valve stems are tight before inflating tires.
- Be careful to never inflate any tire or other inflatable past its rated pressure to avoid explosion,
or possible injury or death.
Please Note: Not intended for use with regular portable compressors or units meant to be operated with an
open ended air chuck. The Tire Inflation Gun is equipped with a close ended chuck and will hold pressure back,
which could cause the hose to burst.
