SAFETY INSTRUCTIONS (Cont’d) :
• Wear tight fitting clothing and any other required safety apparel when operating or servicing the excavator.
• Wear safety glasses when maintaining or servicing the excavator.
• Exhaust gases can kill, vent engine exhaust outdoors.
• Do not run the excavator where exhaust, arcs, sparks or hot components can contact flammable material, explosive dust
or gases.
• Check fuel and hydraulic tubes, hoses and fittings for damage and leakage. Never use open flame or bare skin to check
for leaks. Tighten or replace any parts that show leakage. Always clean fluid spills. Do not use gasoline or diesel fuel for
cleaning parts. Use commercial nonflammable solvents.
• Do not use ether or starting fluids on an engine that has glow plugs. These starting aids can explode and injure you.
• Clean the excavator before doing any welding. Remove both battery cables (negative (–) cable first). Cover rubber hoses,
battery and all other flammable parts. Keep a fire extinguisher near the excavator when welding.
• Have good ventilation when welding or grinding painted parts. Wear a dust mask when grinding painted parts. Toxic dust
or gas can be produced.
• Stop the engine and let it cool before adding fuel. NO SMOKING!
• Use the procedures in this manual for installing, connecting and jump starting batteries.
