Preventive Maintenance And Service - Kärcher HDS 4.0/20-4 Ea Manual

ATTENTION: Risk of damage. Frost will destroy the
appliance if the water has not been completely drained.
Protect from freezing by storing in a heated area, by
draining the water on the machine or by flushing the system
with antifreeze (use an automotive engine antifreeze or
windshield washer solvent to antifreeze). To flush the
system with antifreeze:
• Unscrew side panel to gain access to motor-pump.
• Disconnect hose and water filter on the pump head.
• Connect a hose directly on the pump head water inlet.
• Place the other end of the hose into a container of
antifreeze.
• Start the machine (without the burner) and allow to run
until antifreeze flows from the end of the wand. Squeeze
and release the trigger of the spray gun several times to
antifreeze the unloader system.
• Also draw antifreeze through the detergent inlet line to
antifreeze the detergent system.
For added protection after anti-freezing, disconnect the
high pressure hose from the machine. After coil has been
drained, reconnect pressure hose.
If the pressure washer is not to be used for an extended
period of time, it is also recommended that the system is
flushed with antifreeze for rust protection.
During storage:
• Lock in the spray lance into the holder on the appliance
cover.
• Roll up the high pressure hose and electrical power cord
and hang them into the respective holders.
Note: Do not twist the high pressure hose nor the electrical
power cord.
