High Pressure Hydraulic Lines Can Store a Great Deal of Energy Exposed hydraulic hoses on the arm or boom could react with explosive force if struck by a falling rock, overhead obstacle or other job site hazard. Extra safety guards may be required. NEVER allow hoses to be hit, bent or interfered with during operation. Battery Electrolyte and Explosive Gases Can Be Lethal Flush eyes with water for 10 – 15 minutes if acid is splashed in the face. Anyone who swallows acid must have immediate medical aid. Call the Poison Control listing in the front cover of the telephone directory. The Operator’s Cab Should Be Kept Clean Clean grease and dirt from pedals and controls.
This contributes to safe operation. Explosive battery gas can be set off by sparks from incidental contact or static discharge. Turn off all switches and the engine when working on batteries. Keep battery terminals tight. Contact between a loose terminal and post can create an explosive spark. Cleaning also provides an opportunity to inspect equipment. Minor damage can be repaired or corrected before major problems result. Disconnect Batteries Before Electrical Service or Electrical Welding Remove cable to negative terminal first when disconnecting cable. Connect positive terminal cables first when installing a battery. Keep the cab floor and consoles free of tools and personal items.
Wear Eye Protection and Safety Clothing – Use Proper Tools Contain long hair, and avoid wearing loose clothes or jewelry that could get caught in controls. Use Low Heat Portable Lighting Hot surfaces on trouble lights or portable work lights can set off fuel or battery explosive gases. Full eye protection, a hard hat, safety shoes and gloves may be required at the job site. While working on the machine, never use inadequate tools. They could break or slip, causing injury, or they may not adequately perform intended functions. Breathing Masks, Ear Protection May Be Required Do not forget that some risks to your health may not be immediately apparent.
Exhaust gases and noise pollution may not be visible, but these hazards can cause disabling or permanent injuries. Maintenance Use Warning Tag During Service Alert others that service or maintenance is being performed and tag operator’s cab controls – and other machine areas if required – with a warning notice. NOTE The sound level in the closed operator’s cab is 75 dB(A). Additional information on the machine sound and vibration levels can be found in the Shop Manual. Warning tags for controls are available from Daewoo distributors; see Page 1-1 for more information.
Do Not Run the Engine if Repairs or Work Are Being Performed Alone You should always have at least two people working together if the engine must be run during service. One person needs to remain in the oper- ator’s seat, ready to work the controls or stop the machine and shut off the engine. Asbestos Fiber Hazard Materials containing asbestos fiber can be present on the job site. Breathing air that contains asbestos fiber can ultimately cause serious or fatal lung damage. To prevent lung damage from asbestos fiber, observe the following precautions. 1. Use a respirator that is approved for use in an asbestos-laden atmosphere. 2. Use water for cleaning and for keeping dust down. 3.
NEVER use compressed air for cleaning. Mega 300-III Shop Manual SAFETY 1-11
