Safety Precautions
Springs
Compressed springs (Fig. 4 below) will expand with great force when released, and springs that are stretched will
contract rapidly when released. Know what direction a spring will move and how it might affect another
machine part when released, and stay out of its path.

Burn Points
Be aware of burn points: mufflers, manifolds and even gear cases under adverse climatic conditions. They may
not be severe enough to seriously maim, but they can startle the operator enough to cause him or her to "jump"
into more deadly danger.
Hydraulic Systems
Hydraulic systems contain fluid under extreme pressure. Before loosening, tightening, removing or otherwise
working with any fittings or parts, relieve this pressure. Jet streams from even pinhole leaks can penetrate flesh.
In addition, the liquid is often hot.
Before attempting any service on hydraulic systems, shut off the engine that powers the hydraulic pump. Lower
the implement to the ground and relieve the pressure. Follow instructions in the operator's manual because the
specific procedures for servicing the systems are very important to your safety.
