General rules
Range of application
Use machines for cleaning tasks with high-pressure water jet and detergents or with
high-pressure water jet without detergents only.
Inspections
The machine must be inspected according to the “Guidelines for Liquid Spray Devices”
at least once every 12 months by a qualified person, to ensure that continued safe ope-
ration is guaranteed. The results of the inspection are to be recorded in writing. This
may be done in any form. For inspection reports see pages 38-39.
High-pressure cleaners used for commercial purposes have to
be checked by a qualified person at least every 12 months!
Accident prevention
The machine is designed for accidents to be impossible if used correctly.The operator is
to be notified of the risk of injury from hot machine parts and the high pressure water jet.
The “Guidelines for Liquid Spray Devices” must be complied with. (see pages 8 and 9).
Oil change:
1. The first oil change should be carried out after approximately 50 operating hours.
After that no further oil change will be necessary for the life cycle of the high-pressure
cleaner. UPut the machine into a horizontal position, then open the oil discharge screw at
the bottom of the device over a collection reservoir. The oil is to be caught in the reser-
voir and disposed of in an approved manner.
New oil: 0.25 l - Motor oil W 15/40.
Oil leakage: If oil leaks contact your nearest after-sales
service (dealer) at once. (Ecological damage, damage to
the transmission)
In case of increased humidity or fluctuations in
temperature development of condensed water is possible;
if the oil turns grey, you must change it.

Safety precautions
Bear in mind that during cleaning tasks
with a high-pressure water jet a significant
recoil at the lance arises (see technical
data on page 4).
Apply the safety catch on the spray
gun after each use, in order to prevent
unintentional spraying!
Always aim the underbody lance! Bear in
mind when using a curved or angled
spraying lance that there is a significant
amount of torque in the recoil!
8
Safety precautions - This is prohibited!
Never direct the water jet at people
or animals!
Only use power cables which are in
perfect working order! Do not dama-
ge the power cable or repair it incor-
rectly!
Never pull the high pressure hose
if it has formed kinks or “nooses”!
Never pull the hose over sharp
edges!
9
Safety precautions - This is prohibited!
Never allow children to use the
high pressure cleaner!
Never direct the water jet at the
machine itself!
Never expose the machine to the
spray mist of the high-pressure water
jet!
Never direct the water jet at a
power socket!

Please note - important:
Lack of water
Lack of water occurs more often than you
probably believe. The more powerful a
high-cleaner is the greater is the danger
that a lack of water occurs. If there is only
an insufficient amount of water available,
cavitation (water-gas mixture) arises inside
the pump, which is normally noticed too late
or even not at all.
.
The pump will be destroyed!
Please check the available quantity of water
by filling a bucket with litre scale for one
minute
.
If the metered quantity of water is too small, you have to use a diffe-
rent water connection, guaranteeing the necessary output.
Lack of water leads to an accelerated wear of the joints (no guaran-
tee)
A minimum water quantity of 7 litres per minute must be available to guarantee a
trouble-free operation of the Kränzle 122 Silent.
Water supply
Please pay attention to the regulations of your waterworks company!
In accordance with DIN EN 61770, the machine may not be directly
connected to the public drinking water supply lines. A brief connection
however is permissible according to DVGW (German Association
for Gas and Water Affairs) if a non-return valve with tube ventilator
(Kränzle order no. 41.016 4) is built into the water supply
. Once the
water has passed through the non-return valve it is no longer con-
sidered as drinking water.
Also indirect connection to the public drinking water supply lines is permissible by way
of free emission in accordance with EN 61 770; e.g. by using a reservoir with a float
valve.
Direct connection to a non-drinking water supply line is permissible.
