1. Safety Instructions • • • • •
All operators should be properly trained. All operators should not wear loose clothing or jewelry. These things may become entangled with the wheel or turntable while using the changer and could cause serious injury. All operators should wear protective eye gear. The tire changer contains electrical components and should be kept indoors and in a dry environment. Exposure to water can cause damage and is not covered under any warranty. Other safety regulations may be in place according to OSHA or your local city and county. These should all be followed in addition to the instructions in this manual.
2. Product Description Please see www.nationalautotools.com for the specifications on your tire changer.
3. Assembly You tire changer should include all of the following parts: Assist arm parts packaged in smaller box on top of main tire changer: In addition to these parts, the main body of the machine is included. With some preinstalled parts and internal air lines preinstalled. Steps of assembly:
1. Install air gauge to water separator on back of machine See
picture: 2. 3. Place hexagon mounting bar through hole in horizontal swivel bar. The place the large spring over the hexagon bar. Next with the help of another person, push spring down while placing plastic cap on top of hexagon bar and use the hex bolt
to keep in place. See picture:
4. The result will look like this:
Remove side panel of machine. Install air tank on back of machine.
Connect two large hoses from inside machine to the Y air tank fitting.
Install tilt back arm on center of machine. Place column on back of machine and insert pin.
Place column in upright position and connect small hose inside machine.
Hook small air hose from inflating black box to the 90 degree fitting on the back of the
tire machine. See picture:
Install assist arms
Place RAA-001 mounting plate on main machine body and align with the holes. Use some tape to hold RAA-001 plate in place. Position RAA-011 main assist arm in position as shown in above picture.
Use mounting bolts to bolt assist arm on machine. This must be done for both assist arms on both sides. Wooden boxes have stickers to indicate which side the assist is for. The taller assist arm is for the left side of the machine.
Connect hoses to assist arms as shown in pictures.
Hose connections should be identical on left and right side.
Hook small air hose from inflating black box to the 90 degree fitting on the back of the
tire machine. See picture:
All air hose should be connect on the machine and it is safe to proceed with assembling assist arms and connect cylinder to tilt back column. Connect air to the air gauge on back of machine. Use your own regulator on your compressor to keep air at 100-120 PSI.
Now with someone slightly tilting back the middle column, have another person press the foot pedal that controls the tilt back motion. This should extend the rod of the cylinder
out of the top of the machine. Place the other pin through the cylinder and arm as shown in picture.
Now you can continue with assembly of the assist arm. First place top assist arm(arm with up/down controls that is pre-installed to main assist arm) and bottom assist arm in place as shown below.
Then place RAA-002 assist arm mounting rod through both assist arms as show below.
Then use 2 of mounting bolts in top 2 holes of RAA-002.
Now use up/down switch to raise preinstalled rod up and inside RAA-002 as shown below. Then use the other mounting bolt to finish connection.
Now install remaining assist arm parts as shown in above pictures. Installation is now complete. Place side panel back on machine. Be sure to check compressor oil level in oiler on back of machine before use. Always turn off compressor before connecting to the machine. Once connected to machine, then turn on compressor.
4. Usage Summary The following is a summary of the different features and steps to using the tire changer. This is not a complete step by step on how to be an expert tire changer. If you have never used a tire changer, we recommend having someone teach you the ins and outs of the
process. We also recommend that you practice with an old rim and tire that you do not mind scratching. You must have an air compressor hooked to the tire changer for all the features to work. Check the compressor oil level on back of machine each day before beginning to use. Remove all wheel weights from the rim before using tire changer. 1. First step to changing a tire is deflation. Deflate the tire via the valve. Always deflate the tire before beginning the demount process. 2. Remove inflation valve stem from tire. 3. Place wheel on side of tire changer against rubber pad. Hold wheel in place while pressing the bead breaker pedal to separate the tire from the rim. 4. Release foot pedal, rotate tire, and repeat step 3. 5. Repeat step 3 and 4 to separate both side of the tire from the rim. 6. Use foot pedal to adjust the rim clamps for clamping outside of rim or inside of rim. 7. When clamps are in the desired position, place rim and tire on turntable. Hold the tire in place and press the rim clamp foot pedal. Rim clamps will engage the rim and hold in place. 8. Adjust hexagon demount bar so that demount head curve is perpendicular to curve of rim. 9. Unlock hexagon demount bar and lower. Position demount head so that there is about ¼” space between rim and demount head. Lock hexagon demount bar. 10. Use provided crow bar to raise lip of tire above demount head. Let lip of tire come to rest on tire side of demount head. You may also use part RAA-003 on assist arm to help lift the tire. 11. Push pedal to rotate turn table. Rotate turn table until lip of tire is fully above and removed from edge of rim. 12. Repeat steps 10 and 11 for bottom/other lip of tire. 13. Once tire is fully removed from rim, press rim clamp foot pedal to release rim. 14. Unlock hexagon demount bar and raise out of way. 15. Remove tire and rim from tire changer.
5. Maintenance • • • •
Frequently check the compressor oil level of the oiler in the back of the machine. If low, please refill with compressor oil. Do not use any other type of oil. This keeps the air lines lubed and clean and greatly extends the life of the machine. Keep any air holes free of dirt. Grease the spot where the rim clamp jaws move along the turntable. This will let machine work easier and extend its life. Make sure you do not exceed 145 PSI. Remember that the tire changer does not have a pressure regulator. The gauge on the back of the machine is simply that, a gauge. You must put a pressure regulator on your compressor.
6. Errors and Troubleshooting Error Bead Breaker does not move or does not have enough pressure.
Turntable will not turn
Demount hexagon arm will not stay in locked position One of the air functions do not work
Solution Check hose connections and fittings. Check seals inside bead breaker cylinder. If seals are bad, replace seals. Replacement seals were provided with tire changer. Check inside cylinder to be sure there are no gouges in the metal. Check all wire connections. Check foot pedal and electrical switch. If motor is defective, return motor for inspection and repair or replacement. Replace locking plate. Check foot pedal valve, air lines and fittings for leaks. If air is reaching the foot pedal from the air tank, but not being sent on to final destination, then replace foot pedal air valve.
