Using the Mount / Dismount Head on The Unite Tire Changer

Sometimes it’s the little things that can cause the most damage, like improper use of your equipment. With your Unite Tire Changer, the proper positioning of your mount/demount head is essential so that damage doesn’t occur to the tire or rim.

With the cost of rim and tires these days, you do not want to have to pay hundreds of dollars for a new rim or tire. Below is the proper way to adjust and position the mount head. This is a small part of maintaining your tire changer, but something that can prevent a major issue down the road.

The proper way to adjust and position the changer’s mount head:


1. After the wheel is secured to the turntable, pull the overhead swing arm into position so that the mount/demount head is directly over the edge of the rim. Pull the vertically sliding hex shaft down until the mount/demount head comes into contact with the rim. Turn the Locking Lever to lock the hex shaft into place. As the locking lever is engaged, the mount/demount head will move approximately 1/8″ away from the rim’s edge.

2. The mount/demount head roller that is now making contact with the wheel should be properly positioned 1/8″ from the rim edge by turning the swing arm-adjusting knob. This setting will be maintained, as long as the locking lever and adjustment knob are not changed.

NOTE: With the mount/demount headset in the proper position, the operator may move the swing arm in and out of the way without having to reposition the head; so long as the same tires and wheels are being serviced. However, the head should be regularly checked for proper clearance, even when servicing the same tire and wheel combination. Improper clearance can result in damage to the wheel and/or tire.

This is a very helpful and simple procedure that will protect not only your customers' rim and tire but could ensure that you are protected from possible expensive results of misuse.
