Before taking into use
Read and understand the contents of this manual before installing, operating, repairing, maintaining, changing accessories this tool.
Only qualified and trained operators should install, adjust or use the tool.
Please fill some droplets of resin and acid free oil into the air inlet and let the tool run free for a couple of seconds. (E.g. Red Rooster
air tool oil: Order no. Atlub)
Before connecting the hose to the tool please check, whether the hose and the quick coupler are clean. Do this by letting air run freely
through hose and quick coupler, It is absolutely necessary, that quick coupler and hose have a sufficient diameter. Please note, that
the hose is never too big, but mostly too small!
Air pressure at the inlet of the tool during running has to be at the maximum of 6.3 bar. When this pressure is exceeded, unnecessary
wear and/or damage will occur. At the pressure of below 5.5 bar power loss will occur and if the pressure is excessively low, also
additional wear/damage will occur.
The quality of the compressed air must be good, which means clean, dry and this is best assured by means of an air filter. We advise
the use of a complete FRL (filter, regulator, lubricator) unit. The oiler has to be adjusted to approx. 3 to 6 droplets per minute. The air
hose between oiler and tool should never exceed a length of 6 to 8 meters.
In those cases, where it is possible, use of a centralized oiler is recommended by us. This system will allow use of less oil and assure a
perfect lubrication. When using a centralized oiler, oil consumption can be reduced by up to 80%.
If you intend not to use the tool for a longer period of time, it has to be oiled. Please fill some droplets of resin and acid free oil into the
air inlet and let the tool run free for a couple of seconds.
Do not ignore safety precautions!
