7. PRECAUTIONS DURING OPERATION

7.4 BATTERY

BATTERY HAZARD PREVENTION
• Battery electrolyte contains sulphuric acid and can quickly burn the skin and eat holes in clothing. If you spill
acid on yourself, immediately flush the area with water.
• Battery acid could cause blindness if splashed into the eyes. If acid gets into the eyes, flush them immedi-
ately with large quantities of water and see a doctor at once.
• If you accidentally drink acid, drink a large quantity of water or milk, beaten egg or vegetable oil. Call a
doctor or poison prevention centre immediately.
• When working with batteries. ALWAYS wear safety glasses or goggles.
• Batteries generate hydrogen gas. Hydrogen gas is very EXPLOSIVE, and is easily ignited with a small
spark or flame.
• Before working with batteries, stop the engine and turn the starting switch to the OFF position.
• Avoid short-circuiting the battery terminals through accidental contact with metallic objects, such as tools,
across the terminals.
• When removing or installing, check which is the positive (+) terminal and negative (-) terminal.
• Tighten the battery cap securely.
• Tighten the battery terminals securely. Loosened terminals can generate sparks and lead to an explosion.
• When removing battery cap wear rubber groves to prevent electrolyte contact with skin.
STARTING WITH BOOSTER CABLES
• ALWAYS wear safety glasses or goggles when starting the machine with booster cables.
• When starting from another machine, do not allow the two machines to touch.
• Be sure to connect the positive (+) cable first when installing the booster cables. Disconnect the ground or
negative (-) cable first when removing them.
• If any tool touches between the positive (+) terminal and the chassis, it will cause sparks. This is dangerous,
so be sure to work carefully.
• Connect the batteries in parallel: positive to positive and negative to negative.
• When connecting the ground cable to the frame of the machine to be started, be sure to connect it as far as
possible from the battery.
