Installation
Requirements to the air supply
The pneumatic sabre saw works optimally at an operating pressure of 6 bar, measured at the air inlet.
The distance from the air supply to the machine has to be adjusted to the application conditions on site.
We recommend installing an oiler or a maintenance unit upstream the machine for compressed air
preparation. Use acid and resin-free lubricating oil, like SAE 5W - SAE 10W, for proper functioning of the
pneumatic sabre saw. Attention! Do not use viscous oil.
Use an antifreeze lubricant, e.g.:
“Kilfrost”
or “Kompranol N74” in winter and if the compressed air is very moist.
The supplied compressed air has to be free of:
Foreign particles,
humidity.
Pay attention that all hoses:
Have a cross section being large enough,
do not have any restrictions or buckles,
are designed for a minimum operating pressure of 6 bar,
are replaced regularly at preventative maintenance,
have an oil resistant inner surface and an abrasion-resistant outer surface,
are proved and specified to be non-conductive when being used next to electric conductors.
When operating the machine in areas exposed to explosion hazards, always use antistatic hoses, lubricating
oil and antifreeze lubricants, which meet the local safety requirements.
Connecting the air supply to the pneumatic sabre saw
Remove the locking cap from the air connection 3 (see fig. 2). Connect the pneumatic hose (not contained in
the scope of delivery).

Secure machine against unintentional starting and let the machine cool down to the
ambient temperature.
Protection against tipping, tumbling or falling down when assembling/ disassembling the
machine/parts.
CAUTION –Skin exposure to hazardous dusts may cause severe dermatitis. Dust present
at the work place could be disturbed during the maintenance procedure and inhaled. Clean
machine and work place before maintenance work.
WARNING –Danger of explosion! Generation of sparks during maintenance work!
Observe local safety regulations. Avoid use of force when disassembling and assembling the
machine. Always do maintenance work outside areas which are not exposed to explosion
hazards.
PROHIBITION - Eating, drinking and smoking are forbidden during maintenance and repair
work.
NOTICE –Use only original SPITZNAS spare parts, in order to avoid damages.
Otherwise you risk a decrease in machine performance and an increase in maintenance
work. Check the adherence to the technical specifications according to the operation manual
after each maintenance work.
IMPORTANT –There is no warranty for damages and liability is disclaimed, if non-original
spare parts are used.
Maintenance Instruction
Generally, pneumatic machines need little maintenance. If the following rules are observed, the machine
will have the expected long life-time and high reliability. Service life and performance of the machines are
decisively determined by:
The air purity,
the lubrication conditions and maintenance,
the regular control of the compressed air filter, as well as the regular checking of the machine
with regards to external damages.
Disassembly and re-assembly of the machine have to be executed by qualified staff only. Incorrect assembly
can lead to danger of accident for the operator and to defects on the machine. Furthermore we recommend
giving the pneumatic sabre saw a general overhaul by the supplier once a year.
After completing maintenance and repair work and before restarting production make sure that…
all materials, tools and other equipment which are required for maintenance or repairs have been
removed from the work area of the machine,
any fluid leaks have been removed,
all safety devices on the machine have proper function,
the oil level was checked,
fixtures of screw connections are tight,
removed covers, screens or filters were reinstalled.
The employer ensures that all maintenance, inspection and assembly work is done by authorized and
qualified experts.
