MAINTENANCE

ENSURE THAT ALL MACHINE POWER SOURCES ARE DISCONNECTED AND NO WHEELS ARE
CLAMPED BY THE SPINDLE BEFORE STARTING ANY WORK.
5.1

Every 40 working hours

• Check lubricator oil level 2 (Fig. 16): suction rod height should never be fully out. Top up with oil if necessary;
• Clean the machine. Remove all dirt and/or tire residues from the sliding guide jaws.
5.2

Every 100 working hours

• Remove the plug 6 and check gearbox lubricant level 2 (Fig. 17) through the frame hole 1. Top up if necessary.
5.3

Every 1,000 working hours

• Clean and/or replace silencers 1 (Fig. 18):
1. Undo the four retaining screws and remove the left side of the tire changer or undo the fastening screws to remove
the whole pedal support unit from machine front;
2. Undo the silencers 1 onto the pedal distributor controlling spindle and beader;
3. Blow compressed air to clean or replace in case of damages referring to spare parts catalogue;
4. Fit the filters onto their distributors;
5. Fit the tire changer pedal support or side and secure with the screws.
Check the transmission belt 3 (Fig. 17) for wear or proper tensioning.
•
1. Undo the four retaining screws and remove tire changer side panel;
2. Turn the screws 4 motor support 5 to tension up the belt 3;
3. Replace the belt 3 if worn out using genuine parts;
4. Fit the tire changer side panel before continuing with assembly and disassembly procedure;
NOTE: carry out the above checks each time the tire changer experiences a power failure.

Setting the tool for tyre fitting and removal

The tool is locked in position to an hexagon stand through 4 upper horizontal-axis dowels and a lower vertical-axis
screw. The adjusting clamps lock the tool in its working position. Adjusting clamps also set head distance from the
wheel rim. Head top is concave for smoother positioning.
For tool setting a 14" rim with good concentricity degree and standard profile, better if with flat upper edge
and proper right angle to its spin axis, is required.
5.4.1

Adjusting the clamps

Set the clamps before positioning the head. At this stage the head has not been set to its final
position yet but it is close to its final position being locked through the upper dowels.
• ADJUSTING CLAMP TRAVEL FOR "AUTOMATIC" TYRE CHANGER (FIG. 19)
Tyre changers equipped with collapsible stand and telescopic arm, i.e. "automatic" tire changers, have both
horizontal and vertical adjusting clamps for horizontal and vertical distance of the head from the rim, respectively.
Depressurize the air-operated cylinder (remove upper guard and tighten the nut A1 first so to keep the
adjusting clamp horizontally, that is it should be perpendicular to the hex. shaft) and then turn the nut A
to adjust.
• turn the nut A clockwise for shorter travel of the head,
• turn the nut A anti-clockwise for longer travel of the head.
Depressurize the air-operated cylinder (remove upper guard and tighten the nut B1 first to lock the cone with
respect to the roller – see figure 19), and then turn the nut B to adjust the vertical clamp.
turn the nut B clockwise for shorter travel of the head,
•
• turn the nut B anti-clockwise for longer travel of the head.
