Before Starting
• Open service valve(s) to ensure pressure is relieved in receiver-separator system.
• Close valve(s) in order to build up full air pressure and ensure proper oil circulation.
• Check battery for proper connections and condition.
• Check engine coolant level.
WARNING
!
Do not remove pressure cap from a HOT radiator. Allow radiator to cool down
before removing pressure cap. Use extreme care when removing a pressure cap
from a liquid cooling system for the engine. The sudden release of pressure from
a heated cooling system can result in a loss of coolant and possible severe
personal injury.
• Check the engine oil level. Maintain per marks on dipstick.
• Check the fuel level. Add only CLEAN low or ultra low sulfur diesel fuel for maximum
service from the engine.
• Check the compressor lubricating fluid level between bottom and midway of the sight
glass on the separator tank.
WARNING
!
This machine produces loud noise with doors open. Extended exposure to loud
noise can cause hearing loss. Wear hearing protection when doors or valve (s)
are open.
• Close all doors to maintain a cooling air path and to avoid recirculation of hot air. This
will maximize the life of the engine and compressor and protect the hearing of
surrounding personnel.
• Be sure no one is IN or ON the compressor unit.
