Manual Acquisition of wheel distance in the ALS1 Program Manual Acquisition of the internal plane distance in the ALS2 Program Manual Acquisition of the external plane distance in the ALS1 and ALS2 Program Manual input of B value： Press No.10 key ， directly manual adjust B value （Except ALS1 and ALS2，the other modes require to input wheel A、B and D values） If there is a width rule, it can automatically measure the width value. First, pull the ruler to the inside of the tire. When the screen shows the distance and diameter, pull the width ruler to the outside edge of the wheel. Pause for 2 seconds and the width value will be displayed. After you hear the beep sound and then return the width gauge to its home position 3. After entering the wheel dimensions, press the START key to launch a spin of the balancing machine. After the wheel stops, the screen shows the unbalanced value 4. Manually rotate the wheel until the unbalanced position indicator light on the inside or outside is on and the buzzer rings, indicating that the unbalanced weight position is here. There are two ways to apply the unbalanced weight： 4.1 If the balance weight is clamped or applied to the outside of the wheel spokes (such as the outside of ALU2 and ALU4 balance modes), apply the balance weight at the 12 o'clock position of the wheel after the imbalance weight is found 4.2 If a balance weight is applied on the inside of the wheel spokes, the balance weight can be applied by using a pull ruler, or by using a laser indication line Use the gauge to apply the balance weight. The operation steps are as follows: Remove the adhesive paper of the stick on weights and expose the adhesive surface of the balance weight upwards, and place the stick on weight clipped on the gauge head and then pull out the gauge

indicator light is on To keep the position of the wheel still, rotate the ruler, the head of the ruler on the rim, and then on the balance weight , it will be pressed on the wheel rim, pull back the ruler If the laser indicating function is enabled, use the laser indicating line to apply the balance weight. The operation steps are as follows: Manually rotate the wheel to light up all the indicator lights of unbalanced position on the inside. At this time, the laser indicator line will automatically light up, keep the position of the wheel still, and place the balance weight at the position of the indicator line on the rim . Balance weight application position under each mode： 5. After placing the balance weight, press the START key again to run the balancing machine. After the wheel stops, the balance result will be displayed 10. Weight split function The hidden paste of the balance weight can split the unbalanced weight between the two spokes into two parts, so that the two unbalanced weight after the division fall behind the adjacent two spokes, hiding the unbalanced weight, will not affect the beauty of the wheel. This function is applicable to several balance modes such as ALU2, ALU3, ALS1, ALS2, etc. (the icon

performed). Taking ALS2 mode as an example to illustrate the operation method of the hidden weight function. In ALS2 mode, enter the values of A1, D1, A2 and D2 of the wheel, and run the balancing machine to get the test results. If the external stick on weight position is between the two spokes, then the hidden weight function can be used.The operation steps are as follows： 1.After the unbalanced result is displayed, suppose the unbalanced position on the outside is located between spokes 1 and spokes 2, then long press F key to enter the hidden weight function. 2.Digital tube shows "SPO.--1", pull out the ruler, make it close to the wheel spokes, put the ruler on the top of the rim, turn the wheel, make the ruler in the rear of the wheel spokes 1, keep the wheel position still, pull back the ruler, press the START key to confirm. （If the laser indication function is enabled, aim the laser line at spokes 1 and press the START key to confirm） 3.Digital tube shows "SPO.--2", pull out the ruler, make it close to the wheel spokes, put the ruler on the top of the rim, turn the wheel, make the ruler in the rear of the wheel spokes 2, keep the wheel position still, pull back the ruler, press the START key to confirm. （If the laser indication function is already enabled, aim the laser line at spokes 2 and press the START key to confirm.） 4. At this time, the unbalanced weight on the outside is divided into two unbalanced weights behind the wheel spokes. When you rotate the wheel, you can see the two weights positions displayed.

MAINTENANCE WARNING The manufacturer will not bear any responsibility in the event of claims resulting from the use of non-original spare parts or accessories. WARNING Unplug the machine from the socket and make sure that all moving parts have been locked before performing any adjustment or maintenance operation. WARNING Do not remove or modify any part of the machine (except for service interventions). CAUTION Keep the work area clean. Never use compressed air and/or jets of water to remove dirt or residues from the machine. Take all possible measures to prevent dust from building up or rising during cleaning operations. Keep the wheel balancer shaft, the securing ring nut, the centering cones and flange clean. These com- ponents can be cleaned using a brush previously dripped in environmentally friendly solvents. Handle cones and flanges carefully so as to avoid

would affect centering accuracy. After use, store cones and flanges in a place where they are suitably protected from dust and dirt. Perform the calibration procedure at least once every six months. LUBRICATION The only rotating parts of the wheel balancer are the motor and balance shaft. These parts must be periodically lubricated by the operators. If the machine is used very frequently, more than 2hours per day, we should annually check the bearing. And we will check once a year if the machine is used less than 2hours a day. When test, do not open up the bearing so you need insert a screwdriver to test the noise. Due to the function of the bearing is to clamp and support and not suitable to change or remove the grease. In addition, the speed of it is not too fast compared to the machine so no need to change the grease. If you note the run of the bearing abnormal or there is noise, change the bearing. If the customer confirms the bearing is not changed, you only need change the grease. Disassemble the bearing and open up the sealing ring and fill the XHP103 grease. These operations should be guided by the profession personnel and calibrate the machine after changing the grease. If the change of the grease not correctly, it will influence the accuracy of the machine. On this condition, you need to reinstall the sealing ring and assemble the machine and adjust again.
