A. C. MODULAR GENERATOR SYSTEM
Page 3 of 52
Never operate the system with leaks of any type. Clean up any hydraulic fluid that is 
spilled or has leaked out of the system. Hydraulic fluid is combustible, and ignition may 
occur. 
With the exception of oil filter periodic replacement, never modify or remove any of the 
components within the tray assembly. 
Never modify or remove any of the components within the pump or the controls mounted 
to the pump. This includes all fittings and tubing that are originally provided with the A.C. 
modular generator system. 
Never make any adjustments to the pump other than for flow control. If it appears the 
pump needs to be adjusted, contact Smart Power
®
Systems at (231) 832-5525 before
proceeding. Damage to the generator from improper pump adjustment will void the 
system’s warranty. 
Never attempt any adjustments or repairs to the A.C. modular generator system (other 
than pump flow control) while the vehicle engine is running and the PTO is engaged. 
 
Never operate the system with the hydraulic fluid exceeding 175
F. Above this
temperature, hydraulic fluid can rapidly oxidize and deteriorate causing generator 
performance problems. Operating the system while the hydraulic fluid is above 175
F will
void the system’s warranty.
Hydraulic fluid is combustible and toxic. In the event of human contact with hydraulic fluid, 
generously flush body part (eyes, skin, etc.) with running water. Avoid inhalation of any oil 
mist or vapor. Do not ingest hydraulic fluid. In case of fire, use foam, dry chemical or 
carbon dioxide to extinguish flame. 
Do not exceed the wattage rating of the generator. The generator may be permanently 
damaged and the generator and hydraulic components may reach temperatures that could 
cause severe burns upon human contact with the components. Operating the generator 
system at wattages above the system’s rating will void the system’s warranty. 
Disengage the system immediately if a hydraulic fluid leak is detected. Operation of the 
A.C. modular generator system with low fluid level will result in permanent damage to the 
hydraulic components in the system and will void the system’s warranty. 
Do not attempt to operate the generator with the tray assembly top lid open. Do not 
tamper with the top lid interlock switch or the hydraulic fluid level sensor. 
Never attempt to operate the system without hydraulic fluid. Always maintain a fluid level 
between ½ to ¾ full in the sight gage. When installing the system, fill the pump case with 
1 pint of hydraulic fluid (Dexron III) before engaging the system. Failing to do so will void 
the system’s warranty.
