Inspections

The guarantee period is 12 months according to VDMA.

The guarantee is void if changes are made to the safety devices or if the machine is used
at excess temperatures or speeds. The guarantee is also void if the machine is used
with a voltage below the required rating, with less than the required amount of water, with
dirty water and external damage to the pressure gauge, nozzle, high pressure hose and
spray device.
This guarantee is not applicable for spare parts.
Our operating instructions must be complied with.

Guarantee

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 page 14 and 15)

Check the oil level at the oil dip stick prior to each use.
(Ensure horizontal position!)

Oil change:

The oil of your high pressure pump should be changed after approx. 40 hours of operation, or
no later than when it takes an a grey o whitish colour. To change the oil, remove the two
combination screws on the base-plate at the bottom, take off the base-plate and pull out the oil
drainage hose. Put the hose over a container and take off the closure cap. Put the pump in
the horizontal position to drain off all the oil. The oil must be caught in a container and dis-

posed of in a responsible,
legal manner.

Accident prevention

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
operation is guarateed.
The results of the inspection are to be recorded in writing.
This may be done in any form.

The machine can only be operated when the safety trigger is squeezed.
The machine can only be operated when the safety trigger is squeezed. When the lever is

squeezed, the spray gun opens. The liquid is then pumped to the nozzle. The spray
pressure increases and quickly reaches the selected operating pressure.

When the trigger is released, the trigger gun closes and any further spraying of liquid
from the lance is stopped.

The increase in pressure when the trigger gun is closed causes the unloader valve­safety valve to open. The pump remains switched on and continues to pump liquid
through the pump at reduced pressure. When the trigger gun is opened, the unloader
valve - safety valve closes and the pump ressumes pressure spraying from the lance

The trigger gun is a safety device. Repairs should only be performed by qualified
persons. Should replacement parts be required, use only components authorized
by the manufacturer

Lance with trigger gun

The unloader valve - safety valve protects the machine from a build p of excess pressure,
and is designed not to permit an excess pressure to be selected for operation. The limit
nut on the handle is sealed with a spray coating

The operating pressure and spray rate can be steplessly adjusted by turning the handle.

Replacements, repairs, new adjustments and sealing should only be performed
by qualified persons.

Unloader valve - safety valve

Environmental, refuse disposal and water protection
regulations must be observed !

Water and Cleaning System

Water can be connected at mains pressure to the high pressure pump or it can
be sucked directly from a storage tank. The water is then forced under pressure
by the high pressure pump to the lance. The high pressure jet is formed by the
nozzle at the end of the lance.

Cleaning and caring agents can be mixed with the water by a high
pressure injector (not with K 3170 TST)

Excerpt from the Guidelines for Liquid Spray Equipment (ZH 1/46) by the Central Office of
the Professional Trade Association.
Inspection:
Liquid spray equipment should be inspected for safe operation by a qualified person
whenever necessary, but no less than every 12 months. The maker’s or supplier’s
instructions must be followed. The inspection intervals may be extended if the equipment
is not in active use.
In Germany, inspections compliant with the (German) Emission Controls Act may be
required for oil and gas-fired equipment, and the owner must arrange for these to be
carried out independently of the main inspection.
The results of inspections must be recorded in writing and presented to the respective
authorities on demand. There is no set form for these records.

The information in the operating instructions are a part of the inspection

With delayed motor cut-out

Frequent, work-necessitated switching on and off of motors on
machines of this size puts a heavy load on the power network
and causes increased wear on internal electrical parts. That’s
why the motor on the new KRÄNZLE switches itself off 30
seconds after the trigger is released, and switches itself back on again when the
trigger is pressed.

Safety cut-out

When running your high pressure cleaner with hot water of 80° C raised tem­peratures occur. Do not touch the machine without safety gloves!

CAUTION !

CAUTION !

Never use liquid containing solvents such as paint thinners, petrol, oil or similar
liquid matter. Pay attention to the instructions of the manufactur-
ers of the cleaning agents. The seals in the machine are not resistant to
solvents. The spray of solvents is inflammable, explosive and poisonous.

Setting up

Location

Neither set up and operate the machine in rooms where there is a risk of fire or
explosion nor put it into puddles. Do not use the machine under water.

If you forget to switch the machine off after use, or if the gun is not used for 20
minutes, the machine switches automatically to safety mode. It can be re-activated
by pressing the master switch.

Replacements and inspection work should only be performed by
qualified persons when the machine is disconnected from

the power supply, i.e. pull out the plug from the
electrical socket.

Electrical connection

The machine is supplied with an electrical power cord with plug.
The mains plug must be fitted to a standard grounded socket with a 30mA residual current

operated device.
The socket must be protected with a 16A delay action fuse on the mains side.

KRÄNZLE 2170 TST = 220 Volt / 60 Hz (phase-sequence

not significant

)

When using an extension cable, this must have an earthed lead which is properly
connected to the socket. The conductors in the extension cable must have a
minimum cross section of 2.5 mm². Plug connections must be of a spray-proof
design, and may not be located on a wet floor.
(with extension cables of more than 10 m - 4.0 mm2 )

CAUTION !

The use of extension cables which are too long may lead to malfunctions and
start p difficulty.

When using a cable drum, always keep the cable wound as far as possible.

Brief operating instructions

When operating your high pressure cleaner pay attention that
it is in a horizontal position.

1. Connect the high pressure hose with spray gun and machine.

2. Connect to suitable water supply.

3. Flush the air from the pump (open and close the spray gun several times)

4. Make the electrical connection - (220 Volt three-phase current).

5. Switch on the machine and commence cleaning.

6. Af ter completing the work, completely empty the pump (switch the motor on for

approximately 20 seconds without the suction and pressure hoses).
Only use clean water ! Protect from frost !

CAUTION !

Please pay attention to the regulations of your waterworks company. In accordance with
DIN 1988, 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 tube ventilator with check valve (Kränzle Order-No. 410 164) is
built into the water supply.

Also indirect connection to the public drinking water supply lines is permissible by way of
free emission in accordance with DIN 1988, part 4; e.g. by using a reservoir with a float
valve.

Direct connection to a non-drinking water supply line is permissible.

High pressure hose and spray device

The high pressure hose and spraying device supplied with the machine are made of high
grade material, they are also optimized for the machine and marked as required by the appro-

priate regulations.

If replacement parts are required, only such parts that are authorized by the
manufacturer and which bear the markings required by the appropriate regula­tions may be used. The high pressure hose and spray device must be con­nected in a pressure-tight manner. The high pressure hose may not be driven
over, pulled excessively, or twisted. The hose may under no circumstances be
pulled over sharp edges, since otherwise the guarantee is automatically void.
