TM 5-3805-280-10 Safety Respiratory damage prevention Dust coming out from the dust collector fan indi- cates that one or several filter elements are dam- aged. Change the damaged elements immediately. Always dismount all the filters elements to check the functioning of the automatic filter cleaning se- quence. Never disconnect a valve from the cylinder without supporting the controlled element (drill guide ...). Compressed air Compressed air can be dangerous. Burn prevention Never point an air hose at yourself or co–workers. At operating temperature, the hydraulic tank, cir- cuit and components are hot and can be under pres- sure. Any contact can cause severe burns.
Be sure all hoses and fittings are tightly se- cured. A loose hose not only leaks but can come com- pletely off and while whipping under pressure, can injure the operator and others in the area. Always release the pressure and wait for cool- ing before intervening on the hydraulic circuit. Never disconnect a pressurized air hose. Fire prevention EMERGENCY STOPS Fuel or hydraulic oil leaked or spilled onto hot sur- faces or electrical components can cause a fire. The CPA remote control assembly incorporates an emergency stops selector with allows to connect the CPA emergency stops to the machine circuit. Repair immediately any leaks.
Regularly clean the machine to remove all flam- mable materials such as fuel, oil and other debris. Always use approved safety solvent when clean- ing parts or the machine. Have all loose electrical wires connected and tight before operating the machine. When the CPA is installed, place the selec- tor on position A to have the CPA emergency stops active. Prior to any welding operation, make sure that the surfaces and their environment are free of flammable debris. Place the selector on position B to refind the normal excavator safety circuit when the CPA is not used. 1-25
