GENERAL SAFETY PRACTICES
HYDRAULIC SAFETY
WARNING
Hot hydraulic oil can cause severe burns. DO NOT work on the hydraulic system if the oil system temperature exceeds 120 degrees F. (49 degrees C.)
A
Before ANYONE works on the hydraulic system:
1. Lower the boom to the horizontal position.
2.Support the boom to avoid unintentional lowering.
3.Shutdown the engine.
4.Remove the key from the ignition.
5.Clean the area around the oil reservoir cap (A).
FLUID UNDER PRESSURE
WARNING
Escaping fluid under pressure can penetrate the skin and can cause serious personal injury.
Use a piece of cardboard or paper to search for leaks.
DO NOT use hands! Before disconnecting hydraulic lines, be sure to relieve all line pressure. Before applying pressure to the system, be sure that all connections are tight. DO NOT apply pressure to a damaged line, hose or fitting.
If injured by escaping fluid, see a doctor at once. Proper medical treatment must be administered immediately. A serious infection or reaction can result without proper medical treatment.
WELDING PRECAUTIONS
WARNING
DO NOT weld on any structural member. Any unauthorized welding can cause structural failure or possible personal injury. All unauthorized welding or repair procedures will void the machine warranty.
Before performing any authorized welding, be sure to discon- nect the positive lead from the battery. Properly attach the ground cable of the welder to the frame member that is being welded. Failure to do so can cause electrical system damage.
