Do not remove radiator cap when the
cooling water temperature is high
Engine-powered trucks
Immediately after the engine is shut down, the

Hydraulic oil is hot immediately after the
engine is shut down
Immediately after the engine is shut down, the
hydraulic oil is hot and in high pressure. Do not try
to drain the hydraulic oil or replace the filter. Hot oil
might spout out to cause burns.
Release oil pressure before working
The hydraulic circuit has residual pressure. Before
working on the system, release the pressure. To
check for oil leaks, wear safety glasses and gloves
and use a piece of cardboard or wood. High pressure
oil penetrates the skin. It can cause blindness.
Checking of accumulator and piping is
hazardous
Inspection of piping where an accumulator is
installed is hazardous. When it needs to be
inspected, ask your UniCarriers dealer.
Use caution when removing the
accumulator and its hydraulic lines
Before removing the accumulator or hydraulic lines
from the truck, make sure to shut off the engine and
pump the brake pedal at least 10 times to remove
the oil pressure from the accumulator and lines.
Incomplete removal of the accumulator oil pressure
might cause a burst line or a spurt of oil under high-
pressure.
Precautions to take when handling the
hood gas damper

•
pressure gas is sealed inside it).
Disposal of a used hood gas damper must be left
•

it in the trash.
Never throw a used hood gas damper into a fire.
•
When high pressure oil comes in contact
with your body, immediately get medical
attention
Do not try to jump start the truck. The
truck might jerk, causing an accident
