Check (Condition)
DANGER Batteries give off an explosive gas. Do not smoke when handling or working on the battery. Keep
the battery away from sparks and flames.
Battery electrolyte contains sulphuric acid. It can burn you if it touches your skin or eyes. Wear goggles.
Handle the battery carefully to prevent spillage. Keep metallic items (watches, rings, zips etc) away from
the battery terminals. Such items could short the terminals and burn you.
Set all switches to off before disconnecting and connecting the battery. When disconnecting the battery,
take off the earth (-) lead first.
Re-charge the battery away from the machine, in a well ventilated area. Switch the charging circuit off before
connecting or disconnecting the battery. When you have installed the battery in the machine, wait 5min
before connecting it up.
When reconnecting, attach the positive (+) lead first.
DANGER Batteries give off explosive gases. Keep flames and sparks away from the battery. Do not smoke
close to the battery. Make sure there is good ventilation in closed areas where batteries are being used
or charged. Do not check the battery charge by shorting the terminals with metal. Use a hydrometer or
voltmeter.
WARNING Battery electrolyte is toxic and corrosive. Do not breathe the gases given off by the battery. Keep
the electrolyte away from your clothes, skin, mouth and eyes. Wear safety glasses.
CAUTION Understand the electrical circuit before connecting or disconnecting an electrical component. A
wrong connection can cause injury and/or damage.
Examine the electrical circuits regularly for:
• Damaged connectors
• Loose connections
• Chafing on the wiring harnesses
• Corrosion
• Missing insulation
• Incorrect routing of the wiring harnesses.
Do not use the machine if one or more of these faults are found. You must make sure that the electrical circuit
is repaired immediately.
