Operating instructions 

 
 

INTRODUCTION 

Blitz piston compressors are the result of many years 
of experience. Their high quality level and superior 
design are your guarantee for their reliability, long 
service life, and economical operation. In order to 
avoid any unnecessary damage or danger, please read 
these instructions carefully and always follow them 
at all times. 
 

PROPER USE 

This compressor has been designed and built in 
accordance with the latest state of the technical art 
and the acknowledged safety regulations. 
However, its use could cause potential danger to the 
life and limb of the user or a third party, and possibly 
damage to itself and other machinery, if: 

• 

it is used for anything other than its proper 
purpose 

• 

it has been tampered with or converted improp-
erly 

• 

the safety instructions are not observed. 

 
This machine is intended exclusively for generating 
compressed air for driving machinery. Its use for any 
other purpose counts as improper use, and the 
manufacturer cannot be held responsible for any 
resultant damage; this risk must be borne by the user 
alone. Proper use also includes adherence to the 
operating instructions and to the service and mainte-
nance instructions. 
 
We reserve the right to make modifications without 
prior announcement as part of our programme of 
continuous technical improvement. 
 

GUARANTEE 

The guarantee period is six months. 
You have no guarantee claim in the event of: 

• 

operating mistakes 

• 

inadequate maintenance 

• 

incorrect consumable material 

• 

installation of the wrong replacement parts 
(please only ever use original Blitz parts) 

• 

improper technical alterations to the machine 

• 

failure to adhere to the operating instructions.

SAFETY INSTRUCTIONS 

The following safety instructions and precautions 
should be observed in particular, and in addition to 
the safety regulations generally applicable to air 
compressors: 

• 

Keep the operating instructions somewhere near 
the compressor. They have to be readily available 
at all times. 

• 

Make sure the machine is in a safe operating 
condition at all times, and replace defective parts 
immediately if they could have any effect on its 
operating safety. 

• 

Never reach inside the suction or air outlet 
openings when the machine is running. Rotating 
wheels, drive belts, or hot surfaces could cause 
very serious injury. 

• 

Only ever use original Blitz replacement parts. 

• 

Technical modifications or alterations to the 
machine are totally prohibited. 

• 

The limit figures for pressures and temperatures 
must be labelled in a permanent manner and 
never exceeded. 

• 

The machine is only allowed to be operated when 
all the protective and safety devices are in place 
and working perfectly. 

• 

The warning and safety instructions for the 
machine must be observed, and must always be 
kept in a readily legible condition.
