HG3555A/42306 Portable Power Unit
Maintenance
Skin Injection Hazard:
High pressure oil easily punctures skin
causing serious injury, gangrene or
death. If injured seek medical help
immediately to remove oil.
Do not use fingers or hands to
check for leaks.
Depressurize hydraulic system
before servicing.
Depressurizing Hydraulic System
Hydraulic system must be depressurized when per-
forming maintenance or repair on the power unit hydraulic
system. Depressurizing the hydraulic system will also
make tool hose connections/disconnections easier.
1. Stop power unit engine.
2. Move the two flow levers to the 5 GPM position.
System will be depressurized.
3. Before re-starting power unit engine, move the two
flow levers to the NEUTRAL position.

Stop engine before filling fuel tank.
Do not fill fuel tank when engine is hot.
Do not fill fuel tank near an open flame,
sparks, or when smoking. Fuel is
flammable and explosive and, if ignited,
will result in severe injury or death.
Do not run the power unit engine in a confined
area. Engine exhaust fumes are toxic. If inhaled,
exhaust fumes can cause injury or death.
Do not disconnect tool, hoses, or fittings while
the power unit is running or if the hydraulic fluid is
hot. Exposure to hot hydraulic fluid can cause
serious burns.
Inspect the hydraulic hoses and couplings every
operating day. Repair or replace if leakage,
cracking, wear, or damage is evident. Damaged
hoses or couplings can fail, resulting in injury or
property damage.
