Warning notes
Danger of serious injury and damage due to explosion, fire and
chemical burns!
When charging vehicle batteries, a highly explosive electrolytic gas mixture
(hydrogen and oxygen) is released; it is easily flammable and may release
highly acidic battery acid.
Wear safety goggles whenever servicing a battery.
Follow safety instructions on the outside of the battery.
Do not smoke.
Avoid fire, open flame and sparks.
Avoid sparks when handling cables and electrical devices, and through
electrostatic discharge.
Do not connect the minus pole of the battery jumper cable near to the
discharged battery (generates sparks).
Always remove negative battery ground cables first and install them
last to avoid sparks.
The vehicles must not touch (sparks will occur on connecting the
positive poles).
Never short-circuit the battery.
Ventilate batteries thoroughly before any external start.
When connecting the connecting lead, do not bend over the battery.
Avoid skin and eye contact with any battery acid that escapes.
Keep unauthorized persons clear of the battery.
Ensure that the battery voltage matches.
Never disconnect the batteries while the engine is running.
Serious injury to persons and damage due to water hammer effect!
If water delivery via a pipe or hose is interrupted abruptly, a pressure impact
known as the water hammer effect occurs; this is noticeable as a harsh
noise (like a hammer hitting a pipe). This water hammer can cause severe
injury when handling fire-fighting equipment, as well as damage to lines,
hoses, pumps, valves or other pieces of equipment.
Perform adjustments of nozzles, hydrants, valves etc. slowly.
Before opening a discharge outlet, keep a tight hold on the tips and
nozzles.
Before uncoupling a hose, relieve the pressure.
In case of danger for persons (e.g. due to a burst hose) immediately
reduce the pump speed or close the affected discharge outlet. Switch
off the pump system if needed.
