DUAL 380C ONBOARD AIR SYSTEM
TIRE INFLATION GUN OPERATING INSTRUCTIONS
Your Onboard Air System also comes with a Tire Ination Gun for airing up tires and adding compressed air to
any inatable items with a valve stem.
1. Using the Tire Ination Gun:
Use a 1/4“ Quick Connect Coupler, connect the Tire Ination Gun to an air hose and connect to a tire valve
stem or similar ination collar by securing the folding lever on the Ination Gun air chuck.
2. Filling Tires and other Inatable Items:
Squeeze the Ination Trigger on the Ination Gun by pressing it towards the handle of the gun. This will allow
stored air from the air tank to ow through the gun and through the chuck into your tire or other inatable items.
3. Checking Tire Pressure:
To check tire pressure, release Ination Trigger on Ination Gun and allow the needle of the 0-200 PSI gauge
to settle. Tire pressure will be able to be read only when the ination trigger is released.
WARNING:
- Never operate the Ination Gun at any pressure exceeding 200 PSI.
- Use caution when attaching or removing air chuck from valve stems.
- Always ensure that tire valve stems are tight before inating tires.
- Be careful to never inate any tire or other inatable items past its rated pressure to avoid explosion,
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 Ination Gun is equipped with a close ended chuck and will hold pressure back,
which could cause the hose to burst.
