INSPECT Check    
DANGER Risk of death  caused by vehicle slipping or toppling off of the lifting platform. Align vehicle between the columns of the hydraulic hoist and position the four support plates below the hoist support points specified by the vehicle manufacturer. AS00.00-Z-0010-01A
1 Check tires on all wheels IMPORTANT Check tread as well as outer and inner sidewalls on all tires for signs of damage such as cuts, punctures, cracks, breakouts, separation and ingressed foreign matter. If damage is present ↓

2 Check tire wear pattern on all wheels IMPORTANT Greater wear at the shoulder compared to the center of the tire is normal for the front wheel tires. Wear on the rear tires is uniformly distributed across the total tread, whereby wear on vehicles with rear-wheel drive in the middle of the tread is somewhat greater than at the shoulders. In the event of an unusual wear pattern the cause of the increased tire wear should be established and eliminated.

3 Measure the depth of tread of the tires on all the wheels and note the measurement in the table on the maintenance sheet. IMPORTANT Measure depth of tread at point of greatest wear. Perform measurement at outside, inside and center of tread.
Minimum depth of tread 1.6 mm.
IMPORTANT For safety reasons, tires should be replaced before the minimum depth of tread is reached:
  • Summer tires for approx. 2 to 3 mm depth of tread
  • Winter tires at approx. 4 mm depth of tread
 
IMPORTANT Information on measuring tire tread depth All models AH40.10-P-0006-01T 
    SPECIAL TOOL Brake pad gauge Fig 2
4.1 Change round wheels on front and rear axles If necessary, and only on vehicles without mixed tires
NOTES Retain running direction of wheels, as otherwise handling performances and comfort may be impaired and tire wear increased.
