Power Supply; Water Supply - Kärcher 725 M plus Manual

Safety instruction for high-pressure cleaners
Before using the machine please read the opera-
ting instructions for your unit and comply in parti-
cular with these safety instructions.
The warning and information signs attached to
the unit provide important information for safe
operation.
Apart from the information in the operating instruc-
tions comply with the general safety regulations
and regulations for the prevention of accidents.

Power supply

The voltage indicated on the rating plate must cor-
respond to the voltage of the power source.
Class I units may only be connected to properly
earthed power sources.
We recommend that this equipment is only con-
nected into a socket which is protected by a cir-
cuit-breaker that would be actuated by a 30 mA
residual current.
Only use or replace power supply cables for this
unit which correspond to the types indicated by
the manufacturer. See the operating instructions
for the order no. and types.
If the plug is damaged, pay attention to the follo-
wing: Plugs and sockets confirming to BS 4243 or
BS 196 should be used wherever practicable. Do-
mestic pattern plugs to BS 546 should not be
used. The wiring of the plug should leave more
slack in the earth continuity conductor than in the
other cores, so that it is not the first core to be
pulled out of its terminal should the cord grip fail.
Plugs which have good grips capable of maintai-
ning a firm hold on the cable sheath should be
selected. In general, additional means should be
provided to relieve stress on cable terminations in
the plug. For example, additional cable clamps
should be fitted or a substantial chain could be
used to tether the machine to a fixed point. Plugs
and sockets situated near the work site or out-
doors should be to class IP 55 of BS 5490 to pro-
vide adequate protection against ingress of wa-
ter, etc. and cable entries require effective
sealing. Rubber shrouds should be provided over
cable glands. Drip-proof (class IP X2 of BS 5490)
plugs and sockets to BS 4343 are suitable for use
indoors where the plug is away from the water
spray area where the appliance is in use.
Never touch the mains plug with wet hands.

Before start-up please read these instructions !
Do not run over, crush or pull the power supply
cable or extension lead, otherwise it may be da-
maged. Protect the cable from heat, oil and sharp
edges.
The extension lead must have a cross section in
accordance with the operating instructions and
be protected against splashed water. The con-
nection must not be in water.
When replacing couplings on the power supply
cable or extension lead the spray water guard and
mechanical stability must remain in tact.

Water supply

company.
All connecting hoses must have properly sealed
joints.
The high-pressure hose must not be damaged
