The PriorityStart HD (Heavy Duty) Unit from BLI International is a totally automatic battery protection system that disconnects at 11.7 volts, stopping a dead battery, and then reconnects with simple load change. This new HD unit handles heavier loads, with a 60% increase to 1,600 starting amps and 400 continuous amps. The increase to the contact disc, gears, and holding nut have strengthened the load capability and reduced the stress from heavier loads. Other improvements include increased points of connection, brighter top LED for easy viewing, motor/gear shielding strengthening operation, and a modified top post that easily accepts side mount installation.
Key features on the T7700 and T7800 tire changers include an integrated wheel lift that helps reduce technician fatigue when handling heavy wheels.
