Mannesmann Demag RRI-90 Betriebsanleitung Seite 11

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! For
type RRI-90 an internal diameter of the hose of 8 mm is recommended.
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.
