Requirements to the air supply
The pneumatic hammer drill works optimally at an operating pressure of 6 bar, measured at the air inlet.
The distance from the air supply to the pneumatic hammer drill should not be longer than 5 m. 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 hammer
drill. Attention! Do not use viscous oil.
Use an antifreeze lubricant, e.g.:
•
"BP-Energol AX 10",
•
"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.
Always use hoses, lubricating oil and antifreeze lubricants, which meet the local safety requirements for use in
areas exposed to explosion hazards.
Connecting the air supply to the pneumatic hammer drill
Remove the locking cap from the air connection 3. Connect the pneumatic hose (not contained in the scope of
delivery). For underwater use, additionally connect an exhaust hose (not contained in the scope of delivery) to the
threaded nozzle 4. Optionally, you can screw in a sound absorber instead of a threaded nozzle.
Mounting the drill bit
Ensure the machine is not connected to the air supply, when mounting the drill bit.
Open the drill chuck 6 by turning, until the drill bit can be mounted. Insert the drill bit. Put the drill chuck key 7 (see
fig.3) into the corresponding holes of the drill chuck 6 and tighten the drill bit evenly.
