Maintenance And Cleaning - Hazet 9048 P-1 Instrucciones

Engine block: Connect the HAZET cooling
system cleaner to the upper radiator hose
and collect the water via the lower radiator
hose .

9. Check the radiator hoses, the thermo-
stats and the water pump and replace as
necessary.
Filling the system
10. Firmly tighten the drain valve
underside of the radiator. Ensure that all
hoses are correctly attached.
11. Fill the cooling system with the correct
coolant as recommended by the vehi-
cle manufacturer and ensure that you
bleed the cooling system correspon-
dingly in accordance with the vehicle
manufacturer's instructions. When the coo-
lant is drained from the cooling system it is
replaced with air. When the system is refilled,
air can become trapped in the cooling cir-
cuit. Air in the system must be avoided at all
costs. Air bubbles considerably reduce the
coolant circuit and can lead to overheating of
the engine. Furthermore, they accelerate the
corrosion process and reduce the service life
of the system. Some systems are equipped
with an air-bleed valve on the upper radiator
hose through which trapped air can escape
from the system. Other systems require the
expansion tank to be removed or to be lifted
upwards so that the trapped air can escape.
For this reason, HAZET recommends that the
vehicle maintenance instructions are checked
to ensure that the prescribed air-bleeding
procedure is used.
12. Check the radiator cap
expansion tank cap
replace where necessary.
13. Check the coolant level of the engine
at operating temperature, and top up as
required after the engine has cooled.
14. Carry out a final visual check to ensure
that there are no leaks. Bear in mind that
some leaks only become visible when the
engine is cold, and others only become visi-
ble when the engine is hot.
CAUTION
Take particular care when flushing
cooling systems that are in poor
condition.

4. Maintenance and cleaning

• We recommend that white spirit is used to
clean tools or components thereof.
• Never clean with solvents or acids, esters
(organic compounds comprising acids
and alcohol), acetone (ketone), chlorinated
hydrocarbons or oils containing nitro hydro-
carbons. Do not use any chemicals with a
low burning point.
• For customer service, please contact your
HAZET distributor.
5. Malfunctions
If malfunctions occur, check the following:
• Compression system and compressed air
supply line, air consumption l/min and hose
diameter according to the technical data of
the tool
• Check the compressed air for the occurrence
of dust, condensate and rust particles
• Excess lubrication of the air motor
