Operation (Continued)
5. Check implement hydraulic system
Check hydraulic system and lines of the implement to be attached to the Hydraulic Power Pack. Small
leaks in hydraulic lines can be an indication of catastrophic failure in the near future. The life of
hydraulic hoses may be from a few months to a few years, depending on use and storage patterns.
WARNING: Pressurized Fluid Hazard
High fluid pressures and temperatures are developed in Hydraulic Power Packs.
NEVER check for leaks with your hand. Leaks can be located by holding a piece of cardboard or wood (at least
two feet long) with your hand at one end and passing the other end over the suspected area (wear eye
protection). Look for discoloration on the cardboard or wood.
STOP the engine, disconnect the spark plug, and move all control valve handles back and forth to relieve
pressure before changing or adjusting hydraulic system components such as hoses, tubing, fittings, or other
components.
NEVER adjust the pressure setting of the pump or valve
Hydraulic fluid escaping through a pin-sized opening can burn or puncture skin, resulting in wounds that could
cause blood poisoning, infection, disability, gangrene, amputation, or death.
If injured by escaping fluid, no matter how small the wound is, see a doctor at once. A typical injection injury
may be a small puncture wound that does not look serious. However, severe infection or reaction can result if
proper medical treatment is not administered immediately by a doctor who is familiar with injection injuries.
6. Fill engine gasoline tank (the upper tank)
• Check gasoline tank level.
• Fill tank with fresh unleaded gasoline from a UL approved portable container.
WARNING: Gasoline Vapor Hazard While Fueling
Gasoline is highly flammable and explosive. Heat, sparks, and flames can ignite gasoline vapors which spread
over a large area during fueling. A flash fire ignition and/or explosion will likely result in serious injury or death.
The following conditions could result in gasoline ignition/explosion:
Refueling and refueling spills
Gas vapor collection inside enclosures
Static electric sparks
Sparks from electric wiring, batteries, or running engines
Sources of heat (such as a hot engine exhaust)
Open flames, including pilot lights
7. Inspect fuel system for leaks (with engine off)
Inspect the entire fuel system. Look for signs of: leaks or deterioration; chafed or spongy fuel hose; loose
connections; loose or missing fuel hose clamps; damaged gasoline tank; or a defective gasoline shut-off
valve.
WARNING: Fuel Leak Hazard
A leaking fuel line or spilled fuel no matter how small can be the source of a fire or explosion when starting or
operating the engine.
If Hydraulic Power Pack is in an enclosed area and you smell gas, DO NOT start engine! DO NOT light a
match. DO NOT flip on an electrical switch.
Exit area immediately leaving doors open and call fire department.
