3. Repair safety instructions
Safety instruction for work on electrical wiring
Disconnect the battery when carrying out any repair in the charging circuit to avoid incidental short-circuits. •
When dismantling, rst disconnect the cable from the negative pole (-), then from the positive one (+).
•
Do not disconnect batteries when the engine is running!
•
Connect the “minus“ pole of the battery to the chassis and the “plus“ pole to lead “B+“ from the alternator. In case of the reverse
•
connection the whole semiconductor device could get destroyed.
When starting with auxiliary external supply, do not disconnect such supply sooner than the battery of the machine is connected.
•
Watch out starting voltage of the auxiliary external supply (for 24 V).
Do not put the alternator into no-load run, i. e. with the wire disconnected from the “+“ terminal and connected “D+“ terminal.
•
Do not check the presence of voltage in the wire by sparking it on the chassis of the equipment.
•
Do not do anything that produces sparks.
•
When handling batteries, use protective rubber gloves and goggles.
•
Protect your skin and clothes from stains by electrolyte or lead particles.
•
When electrolyte gets into your eye, rinse it with a stream of water for a few minutes. Then see a doctor as soon as possible.
•
When electrolyte stains your skin or clothes, take o your clothes, wash the stained area with soap water or with a solution of
•
baking soda and water and see a doctor.
After taking electrolyte incidentally, drink as much milk or water as possible or a solution of magnesia and immediately see a
•
doctor.
Never pour distilled water into the cells unless the operation of the machine or charging outside the equipment follows. In such
•
case the battery would self discharge increasingly.
Never add sulfuric acid (H
•
2
SO
4
)!
Do not overturn the batteries because electrolyte could run out of the degassing holes of the battery.
•
If acid (electrolyte) is spilled, rinse the place with water and neutralize it with lime.
•
When the batteries are being charged, hydrogen is released and it makes mixed with air, an explosive, easily combustible mixture.
•
Do not use open ame and do not smoke.
Welding on the machine
Before starting arc welding, disconnect all parts with semiconductors from electrical wiring, inclusive of machine electronics: •
it is necessary to earth both the supply and the machine that is being repaired,
•
secure the supply against moisture,
•
place ground terminal close to the welded joint.
•
when parts are welded or when the machine is in the suspended position, it is necessary to insulate the point of current transfer to
•
avoid current entering the hoist, or to use a non-conducting rope.
Seals
Always use new packing. •
You will receive packing kits as spares.
