INTRODUCTION

Pay attention to rotating components and do not allow
to anyone to approach these areas to avoid becoming
entangled.

Hands, clothing or tools getting caught in the fan blades
or transmission belts, can cause amputations, violent
hemorrages and generate conditions of grave danger.
For this reason avoid touching or approaching all rotating
or moving parts.

A surging spray of the coolant from the radiator can cause
serious burns and scalds.

Before checking the coolant level, shut-off the engine
and allow machine to cool down the radiator and hoses.
Slowly unscrew the cap to release any residual pressure.

If it is necessary to remove the cap while engine is hot,
wear safety clothes and equipment, then loosen the cap
slowly to relieve the pressure gradually.

When checking the fuel, oil and coolant levels, use lights
and lamps explicitly designated as explosion proof. If
these types of lamps are not used, fires or explosions may
occur.

Hydraulic systems

Jets of fluids under pressure can penetrate the skin caus-
ing serious injuries.

Avoid this hazard by relieving pressure before disconnect-
ing hydraulic or other lines.

Relieve the residual pressure by moving the hydraulic
control levers several times.

Tighten all connections before applying pressure.

To protect the eyes wear a facial shield or safety goggles.

Protect your hands and body from possible jets of fluids
under pressure.

Swallowing hydraulic oil is a severe health hazard.
