Safety notes
User operating the high-pressure cleaner should wear the necessary protective clothing, i.e. waterproof clothing, rubber boots, safety goggles, ear protection headwear etc. It is prohibited to use the high-pressure cleaner in close vicinity to people lacking suitable protective clothing.
Use of high-pressure cleaners may result in aerosols being generated. An aerosol is a mixture of floating solid or liquid particles in a gas. Inhaling aerosol particles may cause damage to health. Employers are under obligation to carry out a hazards assessment in order to determine the necessary protective measures to prevent inhalation of aerosols as governed by the surface due to be cleaned in each case. Respiratory masks, Class FFP 2 or higher, are suitable for protection against aqueous aerosols.
Whenever the high-pressure cleaner is left unattended, the mains disconnect switch must always be switched off.
Do not spray against matter containing asbestos or other hazardous substances!
Never spray flammable liquids or liquids containing solvents such as paint thinners, petrol, oil or similar liquids! Explosion hazard due to spraying such materials!
Due to the high-pressure jet, damage may occur on the objects to be cleaned, e.g. car tires; therefore, a minimum distance of 30 cm is to be kept!
Prior to putting the high-pressure cleaners into operation, check its components
(High-pressure hose, power supply cables, safety trigger gun) for any damage.
Replace defect or damaged components!
Only use high-pressure hoses, couplings and fittings recommended by Kränzle.
Only these accessories ensure safety of the equipment.
If use is made of an extension cable, this must be suitable for outdoor use.
In addition care needs to be taken to ensure that the cable is kept dry and that it is situated above the ground. We recommend the use of a cable drum capable of keeping the socket at least 60 mm above the ground.

General rules
Intended use
This high-pressure cleaner is to be used solely for high-pressure water jet cleaning applications without detergents or low-pressure cleaning work with detergents
(e.g. with a foam injector or washing brush).
Environmental, refuse disposal and water protection regulations must be observed!
Inspections
The high-pressure cleaner 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 guaranteed. The results of the inspection are to be recorded in writing (see Inspection reports).
High-pressure cleaners used for commercial purposes have to be checked by a qualified person at least every 12 months!
Accident prevention
The high-pressure cleaner is designed for accidents to be impossible if used correctly. The user is to be notified of the risk of injury from hot machine parts and the high-pressure jet. The “Guidelines for Liquid Spray Devices” must be complied with.
General rules
Oil change
The first oil change should be carried out after approximately 50 operating hours , then every year or after 250 operating hours. If the oil turns grey or white, you must change the oil. In case of exchanging oil being required, the oil drain screw must be opened above a container and the high-pressure cleaner be emptied. The oil is to be caught in the reservoir and disposed of in an approved manner.
New oil: 0.25 l
Kränzle High Performance Gear Oil
(Ord. no.: 400932)

Functional details
Please note: Lack of water
Lack of water occurs more often than you probably believe. The more powerful a highpressure 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 high-pressure pump, which is normally noticed too late or even not at all. The highpressure pump will be destroyed.
Please check the available quantity of water by filling a bucket with liter scale for one minute.
Required minimum quantity of water (see technical data).
If the metered quantity of water is too small, you have to use a different water connection, guaranteeing the necessary output. Lack of water leads to an accelerated wear of the joints (no warranty).
Never let the high-pressure pump run dry for more than 60 seconds.
Water supply
Please pay attention to the regulations of your waterworks company!
In accordance with DIN EN 61770, the high-pressure cleaner 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 item no.: 410164) is built into the water supply. Once the water has passed through the non-return valve it is no longer considered 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.
14
Functional details
Insufficient quantity of electricity
If there are too many collectors in your proximity connected to the network at the same time, the available voltage and the current intensity may decline. Consequently the motor of the high-pressure cleaner does not start or even blows. The power supply may also be insufficient if the power supply cable is too long or too thin. If extension cables are too long, this may lead to a voltage drop causing malfunctions or start-up difficulties.
Check the line fusing and have the voltage and the available current intensity checked by an expert in case of uncertainty (see technical data).
Electrical connection
The high-pressure cleaner is supplied with a 5 meters long power supply cable.
The mains plug must be fitted to a standard grounded socket with a 30 mA residual current operated device. Connection up to the mains must be carried out by a properly trained electrician and must comply with the requirements of
IEC60364-1. The socket must be protected with a 16 A fuse on the mains side.
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 1.5 mm² . Plug connections must be of a spray-proof design, and may not be located on a wet floor. For extension cables of more than 10 m in length, the minimum cross-section must be 2.5 mm² ! When using a cable drum, the power supply cable always must be unwound all the way.
15
Functional details
Water and cleaning system
Water must be supplied to the high-pressure pump under pressure or directly sucked in out of a pressureless container. 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.
Environmental, refuse disposal and water protection regulations must be observed!
Safety jet pipe with safety trigger gun (HD 9/80, HD 12/130)
The high-pressure cleaner can only be operated when the trigger of the safety deactivation trigger gun's trigger is actuated. When the trigger is pulled, the safety deactivation trigger gun opens. The liquid is then transported to the nozzle.
The spray pressure increases and quickly reaches the operating pressure. When the trigger is released, the safety deactivation trigger gun closes and any further spraying of liquid from the safety jet pipe is prevented. The stainless steel pressure gauge must show 0 bar. The increase in pressure when the safety deactivation trigger gun is closed causes the pressure control valve-safety valve to open. The high-pressure pump remains switched on and continues to operate unpressurized via the bypass. When the trigger gun with safety catch is opened, the pressure control valve/safety valve closes, the motor is started and the high-pressure pump resumes pressure spraying from the safety jet pipe with the selected operating pressure.

Functional details
The safety 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.
Pressure control valve/safety valve
The pressure control valve/safety valve protects the high-pressure cleaner from a build up 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.
Motor protection switch
Motor is protected against overload by means of a motor protection switch.
In case of motor overload or blocking, the motor of the high-pressure cleaner switches off automatically. If motor tends to switch off repeatedly, make sure to detect appears. Make sure to detect and remedy the cause of the failure.
Replacements and inspection work should only be performed by qualified persons when the high-pressure cleaner is disconnected from the power supply , i.e. with plug pulled out from the electrical socket.
Totalstop-System
The HD 9/80 TS and the HD 12/130 TS features a totalstop system. If the main switch is switched on, the motor is started via a pressure switch when opening the safety trigger gun. When closing the safety trigger gun the motor is switched off immediately.

12. When using the dirt killer lance make sure that lance points downward when starting.
13. Adjust operating pressureinfinitely using the rotary handle. The maximum pressure is factory-set.
Direct suction
Direct water extraction
Due to the suction capacity of its high-pressure pump (up to 1 m suction height, max. hose length 3 m) this high-pressure cleaners can suck in water for cleaning purposes from separate containers or ponds.
Fig. without TS
1. Mount suction hose with suction filter
(Item no.: 150383).
2.
Put filled suction hose into the waterfilled container and start the cleaning job. Use clean water only! Never suck in water containing chlorine! Do not suction air!
Prior to starting the first suction the high-pressure pump and the suction hose has to be filled with water!
Note
Depending on the water quality it may occur after a prolonged standstill that the valves get sticky. Consequently the high-pressure cleaner cannot properly suck in water from a container. In this case connect a hose with pressurized water to the pump inlet. Having started the high-pressure cleaner the pressurized water opens the valves and the machine resumes sucking in water from the container. Now you can carry on with your cleaning task as usual.
23
Applying additives
Suction of additives
Suction of additives is only possible with mounted lance and control nozzle and/ or Vario-Jet lance requiring adjustment to low pressure.
1.
Place chemicals filter into container with additives. Switch on high-pressure cleaner with opened safety trigger gun.
Fig. without TS
2. HD 9/80, HD 9/80 TS:
To achieve low pressure, push vario nozzle forward and start sucking additive.
Pushing vario nozzle backward causes the high-pressure cleaner to switch to high- pressure. Allow additive to react prior to washing it down with high pressue.
3.
HD 12/130, HD 12/130 TS:
Adjust control nozzle to low pressure and suck in additive. Adjusting control nozzle to high-pressure will cause supply of chemicals to stop. Allow additives to react and wash down with high-pressure.
The additive must reveal a neutral pH value of 7-9. This machine has been designed for use of cleaning agents supplied or specifically recommended by the manufacturer. The use of other cleaning agents or chemicals may impair the safety of the machine. Observe and comply with relevant regulations, e.g. directives governing protective equipment, waste-water regulations, etc.
Attention solvents!
Never suck in liquids containing solvents like varnish solvents, petrol, oil or similar liquids! Seals inside the high-pressure cleaner are no resistant against solvents! The spray mist of solvents is highly inflammable, explosive and poisonous.
24
Taking out of operation
1. Switch off the high-pressure cleaner
2. Cut off the water supply
3. Open the safety trigger gun catch briefly until the pressure is released
4. Apply safety catch on the trigger gun
5. Remove high-pressure hose and safety trigger gun
6. Emptying high-pressure pump: Hold high-pressure hose and switch motor on until water jet stops escaping at the outlet.
7. Pull the plug from the socket
8. Clean high-pressure hose and wind up without loops
