Q & A

What is the first step when using the Hoffman Monte 1625 swing arm tire changer?

The first step is to place the tire onto the tire machine and remove the air from the tire by using the left pedal on the machine.

How do you remove the air from the tire?

To remove the air, first remove the valve cap, then use a valve core screwdriver to loosen the valve core inside the valve stem, allowing the air to escape.

What should you do to prevent damage to the rim during the tire removal process?

It is a good idea to remove any wheel weights from the rim to prevent scratching the rim during the process.

What is the purpose of breaking the bead on the tire?

Breaking the bead is necessary to loosen the tire from the rim. This is done by using the middle pedal to break the bead all around the tire.

How do you begin removing the tire from the rim?

To remove the tire, place it back onto the machine and use the mount and dismount head to line it up with the edge of the rim. Then, lock it in position and adjust the swing arm to avoid contact with the rim.

What should you do if the tire is difficult to pry off the rim?

If the tire is difficult to pry off, turn the tire upside down and lubricate the area between the rim and the tire bead to make it easier to remove.

What is the proper technique for placing the tire back onto the rim?

Lubricate both sides of the tire at the bead and position the tire at a 45-degree angle on the rim. Then, use the mount side of the head to push the first bead onto the rim while spinning it.

How do you ensure the second bead is properly placed on the rim?

To place the second bead, either push down on the tire while spinning it or use the bead pusher tool to assist in the process.

What safety precautions should be taken when inflating the tire?

While inflating the tire, make sure to hold the tire down to prevent air leaks between the bead and rim. Never place your fingers between the bead and rim as this is a safety hazard.

What should you do after inflating the tire?

After inflating the tire to the correct air pressure, reinsert the valve core and tighten it until the valve stem begins to spin. Finally, check the air pressure again and seal the valve stem with the valve cap.
