1 General
This operating manual applies to the PROFI 660 sweeper.
1.1 Intended use
The PROFI 660 sweeper is designed for fitting to wheel loaders and construction machinery.
Because of its robust construction and the various working widths, this sweeper is suited for
permanent use on roads and paths.
The attachment of the PROFI 660 sweeper occurs by means of the mechanical or
hydraulically activated quick hitch unit of the respective carrier vehicle, insertion of a palette
fork in the fork tooth pocket or coupling triangle or adding-on to a three-point linkage.
The PROFI 660 sweeper is suitable as a free-sweeping base machine and thus for cleaning
large fixed surfaces.
The various accessories such as the dirt collector with integrated third support wheel, the
water spray system for fixing dust, one or two side brushes for sweeping near borders, a
hydraulically adjustable side setting for easing the work load, strengthened castor wheels,
limiting lights and warning flags, allow for adaptation to various working environments.

Have the hydraulic hoses checked at least once a year by an expert for operational safety and
condition!
Replace hydraulic hoses with obvious defects, damage and ageing! Use only original hydraulic
hose lines!
The hydraulic hose lines’ period of use may not exceed six years including a possible storage time of,
at most, two years!
Hoses and hose connections are subject to natural ageing even with proper storage and
permissible loading; therefore, their storage time and period of use is limited. Deviating from this,
the period of use can be determined according to the experience values, especially when taking
the danger potential into account. The same guidelines apply for hoses and hydraulic
thermoplastic hose lines.
Never attempt to seal leaking hydraulic hose lines with hands or fingers!
Because of the high pressure, exiting fluids (hydraulic oil) can penetrate the skin into the body
and cause serious damage!
In the case of injury from hydraulic oil, contact a doctor immediately! Danger of infection!
Because of the possible serious danger of infection, never feel for leaks with your naked hand!
When searching for possible leaks, use suitable aids (cleaning spray, special leak-search spray)!
2.4.2 Sweeper
Only one person may operate the sweeper! Alert people present in the sweeper’s hazard zone!
The following is prohibited:
Climbing onto the upper container edge of the collector,
Climbing or holding onto the connecting container while the motor is running!
The presence inside the working area is prohibited!
There is a danger of objects being flung out of the exit opening.
Before operating the sweeper warn people to stay out of the sweeper’s working area!
Do not place objects on the collector!
