Handling

Faults

Legislation stipulates that users must be trained in the use of manually operated blasting

equipment.

The granule jet blasting device is state of the art. To ensure that the equipment operates safely, it

must be operated in a proper and safe manner.

In the interests of quality assurance, we reserve the unrestricted right to apply technical

modifications arising out of further developments in technology and product improvements

without prior notification.

Read the instruction manual carefully before using the device.

All handling necessary to ensure correct operation is described in the instruction manual.

No working method which is not expressly approved by the manufacturer may be used. If the

device malfunctions during use, only trained technical personnel are permitted to repair it.

WARNING

Use of this machine with

nut granulates will produce

allergenic dust.

Persons allergic to nuts

should not use this machine

without adequate respiratory

safety equipment.

Several sections of these operating instructions are marked with internationally recognised warning signs, danger notes and general

prohibition signs. Please comply with all notes and safety rules! The individual symbols are explained in the following.

Follow all instructions and safety rules.

The owner/operator of the machine must make the operating instructions available to the operator and ensure

that they have been read and understood. Only then may the operator start up the device.

1.1 Information regarding this manual

The granule jet blasting device complies with the machinery directive 2006/42 EC and is used to treat the surface

of metal by means of a jet of granules blasted onto the metal surface. Compressed air is used to propel the blast

medium.

The granule jet blasting device is used to remove carbonized material from the inlet channel and valves of internal

combustion engines.

The jet blasting device may only be operated in combination with the vacuum adapters that are approved for the

particular engine type and a vacuum cleaner with sufficient suction power.

Unauthorised modifications or changes to the device are not permitted for safety reasons.

The granule jet blasting device is safe if used for its correct purpose.

If it is used incorrectly and/or negligently by untrained personnel, serious injuries could be caused by the granules

emerging from the device.

The blasting probe must never be used without the suction adapter intended for it and a suction device of

sufficient power.

Never direct the blasting probe at persons or look into the opening of the blasting probe. Risk of injury!

2.3.1 2.3.2

2.2 Sources of danger

2.3 Safety devices

The device must only be operated using hoses which are approved for the purpose of use and the operating pressure of

the device.

The device may only be used by trained personnel.

• Never throw or drop the granule jet blasting device.

• The granule jet blasting device may only be used at ambient temperatures of between 5 °C and 45 °C.

• The granule jet blasting device must not be used in potentially explosive areas!

• The device must never be operated without suitable protective clothing, such as a safety mask and safety shoes. Risk

of injury!

The compressed air must be disconnected and the device depressurised before maintaining and cleaning or

filling the device with granules.

The granule jet blasting device may only be operated with compressed air.

The granule jet blasting device must always be set up on a level surface or the floor of the workshop. The device

must not be set up on tables, workbenches or other objects. (Tank is under pressure!)

Hoses and supply lines must be routed in such a way that they cannot be damaged or disconnected! The hoses must also

be routed in a way that prevents people from tripping over them.

2.3.1

2.3 Safety devices

Fig. 2.4.1

The surface where the device is installed must be level and of

suitable load carrying capacity for the weight of the device and

must be stable.

The device may only be operated in association with the suction

adapters designed for the particular engine type and a vacuum

cleaner of sufficient size and power.

Hoses and feed pipes must be laid so that they cannot be dam-

aged or disconnected! The hoses must also be routed in a way

that prevents people from tripping over them.

2.4 Safety measures at the setup location

If a control function fails, the device must be taken out of service immediately and repaired by a trained technical

personnel!

There is a pressure gauge on the granules tank. The operating pressure of the device must never exceed 8 bar. A

safety valve is installed on the granules tank that controls the maximum operating pressure of the device. The

valve opens at pressure of approx. 8.5 bar.

If the safety setup location malfunction, the device must be taken out of service immediately! The device should

undergo preventive maintenance at least once per annum by a specialist company!

Fig. 2.3.3

There is a 2-way ball valve on the handle of the blasting probe. This can be operated in the event of failure of a control

function. When the ball valve is closed, no air or blasting medium can emerge from the probe.
