Do's and Don't's Table 3.1 Sr.No. Do's and Dont's Photo Ensure air supply to air spring is disconnected while working on air spring or related components. Sudden release of high WARNING pressure air can lead to body injuries. While working on structural. components involving high torques, ensure that all personnel 2 are at safe distance and torque wrench grip is firm. WARNING Torque wrench slippage could cause fatal injury. Allow sufficient clearance around the air spring else, air spring would weaken if metal parts continuously 3 rub with it. CAUTION Weak air spring would fail soon. Use only THSL or TML supplied components/parts/ subassemblies/ fasteners for replacements. Substandard fasteners cannot retain torque for long and work loose. CAUTION Loose bolts make holes oblong and lead to consequential damages Use only THSL_or TML supplied components / parts 5 Spurious parts may fail instantly CAUTION during installation and lead to consequentialdamages Suspension should be greased regularly as per the recommended maintenance schedule. Stub axle cannot move freely CAUTION around king pin due to less or no grease and thus stabilizer can fail prematurely. Air springs and bushes should be protected from exposure to chemicals. They should be covered properly while other works are in progress Such exposure would reduce life CAUTION of airspring and bushes 4 --------------PAGE Number: 8.

CAUTION It leads to premature failure of main air spring due to over extension Don't altervehicle height by adding extra leaves/removing leaves from suspension or by any other means. CAUTION It leads to early failure of main air spring due to overextension. Don't tamper structural components by drilling holes or any structural alteration. 10 Alteration would weaken the CAUTION structural parts and can lead to premature failure Do not add spacer below axle seat. 11 Spacer addition would damage CAUTION Stabilizer and leads to premature failure Don't alter the pneumatic circuit or valves provided by OEM. 12 Such changes leads to CAUTION malfunctioning of lifting system and would damage the components. Don't alter the Electrical circuit of solenoid valve provided by OEM.Do not shift the solenoid valve into the driver's cabin for deploying the 13 system when needed. Lowering the axle while vehicle is CAUTION in motion would damage the components and can be dangerous at times. Axle should be lifted as soon as reverse gear is engaged. Vehicle should be driven in reverse 14 direction only after the axle is lifted completely. CAUTION Else stabilizer would fail prematurely. 5 --------------PAGE Number: 9.
