Maintenance
Pneumatic tools require regular maintenance. You will find instructions on this, as well as technical details, in the relevant operating instructions.
Always bear in mind: insufficient lubrication of pneumatic tools leads to increased wear and tear, and the internal parts may corrode. This can result in your device failing completely.
Pneumatic tools must therefore be lubricated during operation. This can be done by a few (1 to 2) drops in the air connection or, better still, by continuous lubrication using a maintenance unit (e.g. 9070-2, 9070-4 or 9070N-1). The oil is necessary for the lubrication of the engine, but also as corrosion protection. Our tip: hold a cloth in front of the air outlet after manual oiling. Excess oil is expelled via the exhaust air.
The oil on a pin clutch mechanism must be reapplied every six months if it is used on a daily basis. Only use special oil for pneumatic tools, e.g HAZET 9400-100 (100 ml) / 9400-1000 (1000 ml) and oiler 2160
Please refer to the pictures for quantities and positioning.
Repairs
Whatever the cause of your pneumatic tool's failure, we offer a comprehensive repair service, which you can send in directly to our Service Centre or via your specialist dealer.
Despite good lubrication, some components in the pneumatic tool are subject to wear. You can also carry out repairs yourself. You can find the right spare parts in our Spare Parts Shop.
Pneumatic tools
The performance of an impact wrench operated on compressed air is influenced by various parameters. A key factor is the compressed-air system to which the impact wrench is connected. As compressed-air systems vary from user to user, it is not possible to specify reliable torque values that apply to all such systems.
For professional workshop use, you will need a large workshop compressor with a tank capacity of at least 200 litres
Smaller compressors are usually unable to supply the impact wrench with a sufficient supply of air over the long term. This means you have to keep taking breaks whilst working so that the compressor can refill the air tank.
The working pressure is always measured directly on the device whilst air is flowing through it. Why not have a look at our pressure loss calculator too?
The air connection nipples we supply usually have sealant applied to the thread; furthermore, most air connection nipples have tapered threads. It is therefore usually not possible to screw them all the way down to the bottom of the thread. If the thread alone does not provide a sufficient seal, you can help by using a little Teflon tape, for example.
Air quality is specified in ISO 8573-1. According to this standard, the air should be as dry as possible (no condensation), oiled (for corrosion protection and lubrication) and free from foreign particles. After the compressor, your system should therefore at least include a water separator, a fine filter and a lubricator.
Training offers
The maintenance and repair of pneumatic tools requires detailed expertise. We teach these skills in training courses that we offer at our modern "HAZET Welt" training centre or directly at our service centre in Remscheid. We can customise the content and scope of the training to suit your individual needs.
If required, simply ask us for the next dates.
