the local government, state or
federal regulations.
• Drain the compressor tank and remove the
condensate from the air lines. Carefully read
through the operating instructions for the
compressor.
IMPORTANT:
We recommend using air filters.
• Lubricate the tool; see the section on main­
tenance in these operating instructions.
• Remove the dust cap on the compressed air
inlet.
• Connect the tool to a hose of suitable
size. Table on page 15.

3. Commissioning
Draining of old coolant
1. Safety is paramount. Wait until the engine
has cooled down before working on compo-
nents of the cooling system.
2. Press down on the radiator cap
slowly anticlockwise until it hisses, wait until
the hissing stops and then remove the cap.
3. Place a large container beneath the drain
valve on the underside of the radiator.

vehicle.
4. Release the drain valve
lant drain completely. If the radiator has no
drain valve, disconnect the lower radiator
hose and allow the coolant to drain. If

the vehicle has a separate expansion tank
, disconnect all connecting hoses from

the cooling system and allow the coolant
to drain.
5. Think of the environment and dispose of the
old coolant properly.
Flushing the system
6. Before commencing work, read the
instructions for use thoroughly and fol-
low them carefully.
7. Prepare the vehicle for flushing.

the heater regulator valve
attempting to flush through the valve. If this
cannot be confirmed it must be removed.
8. Place the stepped pistol nozzle of the
HAZET cooling system cleaner in a hose
that is suitable for the flushing task and
flush the system until the outflow from
the radiator / engine block / heater core
is clear. While water flows through the
system, blow short, intermittent blasts of
air to increase effectiveness.
Radiator: Due to the larger chambers in
the radiator, flushing the radiator initially
allows kinetic waves to pass through the
water, wherein residue is removed more
effectively. Flood the lower part of the radi-
ator. With the radiator cap in place, firstly
flush from the bottom to the top. After one
or two minutes, flush the system from the
neck downwards. Heater core: Connect
the HAZET cooling system cleaner to the
inlet hose
process. Ensure that the heater regulator
valve is open or has been removed, as
