MAINTENANCE PROCEDURES
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.)
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.
