General rules

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.

Oil change

Technical line drawing of a mechanical assembly with no visible text or symbols

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)

Oil leakage

If oil leaks contact your nearest after-sales service (dealer) at once. Failure to observe this instruction may cause damage to the environment and/or transmission gearbox.

In case of increased humidity or fluctuations in temperature development of condensed water is possible. If the oil turns grey or white, you must change it.

Please note: Lack of water

Line drawing of hands interacting with a bucket containing a sensor or sensor, no text or symbols present

Lack of water occurs more often than you probably believe. The more powerful a high-pressure 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 high-pressure 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 61770; e.g. by using a reservoir with a float valve. Direct connection to a non-drinking water supply line is permissible.

Insufficient quantity of electricity

226

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 mm ^2 . 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 mm ^2 ! When using a cable drum, the power supply cable always must be unwound all the way.

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 7/122, HD 10/122)

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.

Safety jet pipe with safety trigger gun (HD 7/122 TS, HD 10/122 TS)

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 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 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 trigger gun is closed causes the pressure control valve/safety valve to open. The motor is switched off by the pressure switch. When the safety trigger gun 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.

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 7/122 TS and the HD 10/122 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.

High-pressure hose and spray device

The high-pressure hose and spray device which are part of the HD 7/122, HD 7/122 TS, HD 10/122 and the HD 10/122 TS equipment, are made of high quality material and engineered to conform with the operating conditions of the high-pressure cleaner and are duly labeled.

If replacement parts are required, only such parts that are authorized by the manufacturer may be used. The warranty is automatically void if spare parts of third-party providers are used! The high-pressure hose and spray device must be connected in a pressure-light manner (without leakage).

The high-pressure hose may not be driven over, pulled excessively, or twisted. The high-pressure hose may under no circumstances be pulled over sharp edges. Defective high-pressure hoses must not be repaired (acc. to DIN 20022) but have to be replaced by new hoses approved by the manufacturer.

1. Carry the HD 7/122, HD 7/122 TS, HD 10/122 or the HD 10/122 TS to its their place of use and ensure secure footing of the high-pressure cleaner.

Do not place the HD 7/122, HD 7/122 TS, HD 10/122 and the HD 10/122 TS on rough surface because the high-pressure cleaner tends to vibrate during operation.

When carrying the HD 7/122, HD 7/122 TS, HD 10/122 and the HD 10/122 TS, make sure to bear in mind the weight of the high-pressure cleaner (see technical data).

It is imperative that safety instructions be observed during use of the high-pressure cleaner.

Neither set up or operate the HD 7/122, HD 7/122 TS, HD 10/122 and the HD 10/122 TS in rooms where there is a risk of fire or explosion nor put it into puddles. Do not use the high-pressure cleaner under water. If, none the less, the high-pressure cleaner is operated in a hazardous area, the applicable safety regulations are to be observed.

1. Unwind high-pressure hose straight and without nooses. The high-pressure hose may leave signs of abrasion on some floors. Alternatively, please also find non-marking high-pressure hoses in our range.

1. Plug screw high-pressure hose included in scope of delivery at pump outlet and tightly screw pressure-tight.

1. Mount the grey rotating screw connection of the high-pressure hose onto the trigger gun incorporating a safety catch. Afterwards screw together ensuring a snug and pressure-tight fit.

1. First pull back the retaining sleeve of the safety trigger gun, then insert lance into the plug coupling sconnection of the safety trigger gun.

1. After insertion of the lance, release retaining sleeve and make sure that the lance is in a secure position. Grease quick release nipple regularly using acid-free grease.

The plug coupling must not be actuated/handled during operation! Igh risk of injury!

Prior to insertion, check plug coupling connection of lance for cleanliness (sand, dirt ..) and use clear water to clean, if necessary. Impurities may damage the sealing in the plug coupling.

When using high-pressure hose extensions take care that the max. length of 20 m is not exceeded!

Accessories may only be connected to a Kränzle-approved trigger gun with safety catch.

7. Check water inlet filter for cleanliness prior to putting the high-pressure cleaner into operation.

Manually unscrew plug-in coupling. Take out the water inlet filter using needle nose pliers and thoroughly

rinse it with clear water and clean it with the other parts. If the sieve is dirty, water can not get through and pressure will not build up.

Check the water inlet sieve for damage. Do not operate the high-pressure cleaner without or with a damaged filter.

Mechanical assembly diagram showing a gear and shaft assembly with directional arrows (no text or symbols)

1. Connect water hose to water inlet (minimum requirements; 5 m hose length, cross-section 14 ", 10 bar). The high-pressure cleaner may be connected to a water mains (1-10 bar pre-pressure) with either cold or hot water (up to 60 °C). The HD 7/122 and the HD 7/122 TS provides the opportunity of sucking in water out of a container (see direct suction).

Be careful when using hot water!

When running your high-pressure cleaner with hot water of 60 °C raised temperatures occur. Do not touch the metal parts of the high-pressure cleaner without safety gloves!

9. Each time check oil level of the oil slight glass prior to putting the high-pressure cleaner into operation.

Oil level must be visible in the middle of the oil sight glass.

1. Connect to circuit (see technical data).

Do not touch the mains plug or any live parts with wet or moist hands.

1. Adjust operating pressure infinitely using the rotary handle. The maximum pressure is factory-set.

Direct water extraction with HD 7/122 and HD 7/122 TS

Due to the suction capacity of its high-pressure pump (up to 1 m suction height, max. hose length 3 m) this high-pressure cleaner can suck in water for cleaning purposes from separate containers or ponds.

Mechanical assembly diagram showing gear and shaft components (no text or labels)

1. Mount suction hose with suction filter (Ord. no.: 150383).

Line drawing of a container with a coiled tube and a handle, no text or symbols present

1. Put filled suction hose into the water-filled 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.

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
9. Clean and wind up the power supply cable
10. Clean the water inlet sieve
11. Store high-pressure cleaners in frost-free rooms in winter

Frost protection

For protecting the high-pressure cleaner against frost please empty it completely. Separate high-pressure cleaner from water supply and switch it on By opening the trigger gun the high-pressure pump presses water out of the high-pressure cleaner. However, do not allow the device to operate without water for more than one minute.

Problem

No water from nozzle although the high-pressure cleaner is running. The stainless steel pressure gauge shows full pressure.

Cause

Most likely the nozzle is blocked.

Illustration showing a person using a tool to measure a large pressure gauge with numerical markings and a worker observing it.

The stainless steel pressure gauge shows full pressure, but from the nozzle comes only little water or no water at all.

(Inside the stainless steel pressure gauge is no water but a filling with glycerin to damp the vibration of the pointer.)

Proceeding:

Switch off the high-pressure cleaner. Pull plug from the socket. Operate safety trigger gun catch several times to decrease the pressure.

Remove safety trigger gun and lance first, then rinse high-pressure hose to remove possible soiling.

Check water inlet filter for soiling.

If the problem still exists, take wire (paper clip) and push through nozzle opening. If this procedure is not successful, the nozzle has to be replaced.

Pull plug from socket prior to starting any repair work!

Problem

Irregular jet from nozzle.

The stainless steel pressure gauge shows low pressure.

Cause

Most likely the valves are soiled or sticky.

Illustration showing a worker using a water spray to clean a large pressure gauge, with a magnified view of the gauge indicating temperature and volume.

The stainless steel pressure gauge shows low pressure despite fully turned up pressure regulation. The water from the lance comes in squirts. The high-pressure hose vibrates.

(Inside the stainless steel pressure gauge is no water but a filling with glycerin to damp the vibration of the pointer.)

Proceeding:

Unscrew all 6 valves, one after the other (hexagonal brass screws, 3 in a row, vertically and horizontally)

Take out valve body and O-ring by means of needle nose pliers. Check O-ring for damage. In case of a damage the O-ring has to be replaced.

Take a wire (paper clip) and clean valves under running water.

Do not forget the O-ring during reassembly!

HD 7/122, HD 10/122

Problem

After closing the safety trigger gun, the pressure control valve-safety valve keeps switching. The stainless steel pressure gauge continuously displays full pressure.

Possible cause No. 1 Leckage.

Technical diagram showing three different mechanical or pressure gauges with labeled dimensions and a close-up of a tool with a water bottle.

Having closed the safety trigger gun, the pressure control valve/safety valve must switch and the stainless steel pressure gauge must show „0“ bar. Failing to switch and with the stainless steel pressure gauge continuously showing full pressure, this could be due to leakage at the high-pressure pump, at the pressure switch, at the high-pressure hose or at the safety trigger gun.

Proceeding:

Check connections from the high-pressure cleaner to the high-pressure hose and from the high-pressure hose to the safety trigger gun and also the connection between lance and safety trigger gun for tightness.

Switch off the cleaner. Shortly press the trigger of the trigger gun with safety catch to decrease the pressure. Remove high-pressure hose, trigger gun with safety catch and lance and check the O-rings. If the O-rings are damaged they have to be replaced.

Applied specifications and standards:

The warranty obligation of Josef Kränzle GmbH & Co. KG towards the dealer from whom you have purchased this Kränzle high-pressure cleaner (= product) applies to material faults only such as material and manufacturing defects.

Defects attributable to long and frequent use of the product, typically arising due to the age of the high-pressure cleaner and intensity of its use are defined as normal wear in respect of product components. Purchaser's rights to assert claims for such defects are ruled out. Parts subject to wear include in particular the pressure gauge, nozzle, valves, sleeves, high-pressure hose and spray equipment

The product is to be operated in conformity with this operating manual. The operating manual is deemed to be part of the warranty provisions.

Any changes made to the safety devices of the product or instances of maloperation – such as exceeding the temperature and speed limits, undervoltage, insufficient water supply and sewage water, or failure to use the product for the intended purpose – may result in damage occurring to the product. Such damage is not deemed to constitute any material defect.

Should the use of accessories or spares other than original Kränzle component parts and original Kränzle replacement parts be the cause of defects on our product, this may lead to all warranty claims becoming null and void. Only the use of original Kränzle replacement parts matching the relevant Kränzle high-pressure cleaner provides adequate assurance for safe and trouble-free operation of the Kränzle high-pressure cleaner.

With regard to legal warranty claims, the limitation periods of the respective countries shall apply.

Where warranty claims apply to any other defects, please contact your local dealer, presenting the accessories together with your purchase receipt, or the nearest authorised service centre. This can also be found on the internet under www.kraenzle.com.
