In case of outward clamping (Fig. 08), enlarge the jaws outward, place the wheel on the turntable and depress pedal H to clamp. Pull back the swing arm and turn the handle of the screw (12) to put the hexagonal column in working position (Fig.09), and keep a distance of 1~2mm from the mount/demount head (Fig.10), and then lock the hexagonal column with locking handle. Note: Fig.05 The angle of the mount/demount head has been adjusted by manufacturer according to standard rim (15"). Re-adjustment may be necessary to prevent scratching the tyre when the rim is extremely large or small. Fig.06 Place the wheel on the turntable. For the asymmetric deep groove rim, keep the narrow rim upward. Depress pedal H (Fig.07) to the end to clamp the rimNote: Different types of clamping can be chosen in Fig.09accordance with different rims. Fig.10 Fig.07 Lift the tyre bead onto the mount/ demount head with tyre lever (Fig. 11). To make it easy, press the tyre opposite to the mount/demount head. After settling it down in the rim groove, depress Pedal J(Fig.12) lightly to turn the turntable clockwise until the rim is separated. To avoid damage to the tube when there is one, it is advisable to place the air inflating valve about 10cm (Fig.13) away from the mount/ demount head. Caution: In case the demounting is hindered, stop the machine immediately. Lift up the pedal J (Fig.12) to turn the Fig.08 turntable counter-clockwise to clear away the hindrance.

Clamp the rim tightly in the same way as demounting tyre. Use lubricant such as thick soap solution on the tyre and the rim. Put the bead on the rim with the left side upward, and pull back the mount/ demount head to the work position (Fig.15) Fig.12 Fig.15 Check the coordination of mount/demount head and rim. Readjust if necessary. Adjust relative position between the tyre and the mount/demount head to make the tyre bead cross the mount/demount head. At the end of the mount/demount head, the tyre bead should be Fig.13 placed on the mount/demount head (Fig.16A). At the beginning of the mount/demount head, the tyre bead should be placed under the ball protuberance of the mount/demount head (Fig.16B). Fig.14 If there is tube in the tyre, remove it. Lift the lower tyre bead after removing the tube from the tyre so that the rim at the relative side enters the Fig.16 groove(Fig.14). Depress pedal H (Fig.07) to loose Press down the central part of the tyre. Depress the the jaw and take the rim off to complete the pedal J (Fig.12) to turn the turntable clockwise, demounting 5

To install the upper tyre bead, place the tyre well and Loose the wheel on the turntable. readjust position of the tyre bead (same as mount of Connect the outlet of the gun to the air inflation the lower tyre bead in Fig.17. Press down the tyre valve. opposite to the mount/demount head to the rim Slowly press the switch on the inflating gun for groove (Fig.18)). several times during inflation to make sure that the reading on pressure gauge meets the manufacturer’s specifications. The pressure should not exceed 3.5 bar. If the pressure exceeds the limit, press the button on the gun inflator so that the pressure goes down to what is required. Caution: Danger of explosion! The safety procedures should be closely followed. Review and abide by the following instructions. Otherwise serious injury or death can be resulted. The manufacturer shall not be held responsible for Fig.17 any possible accident when the safety procedures are not followed. Carefully check the dimensions of rim and tyre to see if they match each other. Check and make sure that the tyre is not worn or damaged before inflation. When a high pressure is required, remove the tyre from the tyre changer and resume the inflation in a special protective hood. Be careful when inflating the tyre. Keep hands and the rest of human body away from tyre Fig.18 Depress the pedal J (Fig.12) to turn the turntable while keeping pressing on the tyre. When only 10~15cm is left, slow down to avoid damage of the tyre bead. Stop the motor if there is any indication for damage. Lift the pedal J and turn the turntable counter-clockwise. Try again when the tyre is back to the original shape. Note: . It is not necessary to move the handle of the screw every time if the size of rim matches the Fig.19 tyre. Just move the swing arm. In the process of operation, keep head and hands away from the area between the tyre and the swing arm to avoid injury.Inflating tyre Danger!! 6
