Safety systems air compressor

WARNING! Danger of death due to non-functioning safety equipment!

Safety equipment ensure highest level of safety in operation. Even if work processes become a little more complicated due to safety equipment, they must never be decommissioned. The safety is guaranteed only with intact safety equipment.

Therefore:

 Before starting work, check if the safety

equipment is functioning properly and has been correctly installed.

 Use safety equipment at all times.  Do not obstruct access to safety systems such

as emergency stop buttons, pull cords etc.

General positioning of the air compressor

The air compressor complies with the national and international safety regulations and can therefore also be used in damp rooms and/or outdoors. Areas with clean and dry air should be preferred. Ensure that the device can freely suck in the air. This applies in particular if an installation is intended.

The air compressor should only be set up in such a way that no dangerous additives, such as solvents, vapours, dusts or other harmful substances can be sucked in. The device should be positioned only in rooms where the hazard of a potentially explosive atmosphere is not given.

Hot surface of the air compressor

General information

WARNING! Danger of injury due to hot surface!

During operation the compressor can reach a surface temperature of up to 100 °C. Therefore it has to be ensured that the device does not get into contact with bare body pars during use as well as for some time after use, in relation to the heating temperature.

Flowability / Flow characteristics

NOTE!

 The pump unit D6-3 can be used up to 30 bar operating pressure.  The pump unit D6-4 can be used up to 40 bar operating pressure.  The possible conveying distance depends mainly on the flowability of the material.  If 30 or 40 bar operating pressure are exceeded the mortar hose length has to be reduced.  In order to avoid machine faults and increased wear of the pump motor, pump shaft and the

pump itself, only original PFT spare parts such as

 PFT rotors  PFT stators  PFT agitators  PFT mortar hoses must be used.  These are compatible with each other and form a constructive unit with the machine.  Non-compliance does not only cause loss of guarantee, but also bad mortar quality is to be

expected.

2016-10-17

Mixing pump G 4 X Super / G 4 X XL Overview - Operation and service

Causes for this can be:

Highly worn mortar hoses, badly greased mortar hoses, residual water in mortar hose, clogging of the pressure flange, strong tapering at the couplings, kink in mortar hose, leaks at the couplings, badly pumpable and demixed materials.

Earlier damage to the mortar hose

Removal of blockages in the hose

NOTE!

If in the event of a machine fault by material clogging the pressure in the mortar hose exceeds 60 bar, even only temporarily, replacement of the mortar hose is recommended as there might be damage in the hose that is not externally visible.

40 Removal of blockages in the hose

DANGER! Danger from discharged material!

Never loosen the hose couplings as long as the pressure head is reduced! Material to be conveyed can be discharged under pressure and cause injuries particularly to the eyes.

Persons commissioned with the cleaning of clogged hoses have to wear personal protective equipment (protective goggles, gloves) for safety reasons, and to position themselves in such a way that they cannot be hit by discharged material. Other persons have to clear the area.
