Safety Section

| Illustration 1 | g00104545 |
Attach a "Do Not Operate" warning tag or a similar warning tag to the start switch or to the controls before you service the equipment. These warning tags (Special Instruction, SEHS7332) are available from your AVSpare dealer.
Note: Drain the hydraulic fluid from the hydraulic tank before opening the hydraulic system. Remember to fill the hydraulic tank with hydraulic fluid once the installation is complete.
| NOTICE |
|---|
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before operating any compartment or disassembling any component containing fluids. After collecting all fluids in suitable containers, dispose of all fluids according to local regulations and mandates. |
 |
Check valves in the hydraulic system may allow pressure to exist in the hydraulic lines after the engine has been stopped. Pressure must be relieved prior to servicing the components of the hydraulic system. Failure to relieve pressure prior to servicing may result in personal injury. |
 |
|
Personal injury or death can result from improperly checking for a leak. Always use a board or cardboard when checking for a leak. Escaping air or fluid under pressure, even a pin-hole size leak, can penetrate body tissue causing serious injury, and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury. |
|
|
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin. |
