REPLACE RUBBER HOSES PERIODICALLY

Rubber hoses that contain flammable fluids such as
hydraulic oil or fuel under pressure may break due to
aging, fatigue, and abrasion. It is very difficult to gauge
the extent of deterioration due to aging, fatigue, and
abrasion of rubber hoses by visual inspection alone.
Periodically replace the rubber hoses.(Refer to the
Periodical Replacement Parts section in the operator's
manual.)
Failure to periodically replace rubber hoses may cause a
fire, fluid injection into skin, or the front attachment to fall
on a person nearby, which may result in severe burns,
gangrene, or otherwise serious injury or death.

AVOID HIGH-PRESSURE FLUIDS

Fluids such as diesel fuel or hydraulic oil under pressure
can penetrate the skin or eyes causing serious injury,
blindness or death.
Avoid this hazard by relieving pressure before
disconnecting hydraulic or other lines. Make sure that
all connectors are completely connected before
applying pressure.
Search for leaks with a piece of cardboard; take care
to protect hands and body from high-pressure fluids.
Wear a face shield or goggles for eye protection.
If an accident occurs, see a doctor familiar with this
type of injury immediately. Any fluid injected into the
skin must be surgically removed within a few hours or
gangrene may result.
