4.2 Mounting on the vehicle
The mounting on the carrier vehicle without any tools!
1.Secure the vacuum machine on a level ground on a Euro pallet against toppling over
2.Remove the four retaining bolts, the assembly frame from the holders and remove all moving
objects from the coupling zones
3.Move the Citytrac slowly up to 20cm in front of the rear fastening points
connect the suction hopper of the Citytrac to the leaf vacuum machine in this position
4.Move the Citytrac as precisely as possible for the remaining 20cm to the leaf vacuum machine
– switch off the engine, switch on the ignition again and activate the floating position
5.Align the lower linkage eyes with the holes of the assembly frame and connect with the
provided mounting bolts
6.Secure the mounting bolts
7.Connect the vehicle hydraulic system to the machine's hydraulic system (also see Section 5.1)
8.If the leaf vacuum machine is hanging with the front mounting bolts, the Citytrac can be started
and the hoist can be lifted slowly until the rear holes of the collector are in position over the
rear fastening points on the lower linkage of the Citytrac – fasten in this position with the
required bolts and secure
4.3 Adjusting the working height
The working height can be adjusted without tools!
•to adjust the working height, raise the device completely so that the chassis hangs above
the ground
•by distributing the spacers on the top or bottom, the desired/required working height can
be set
1. remove the cotter pin
2. remove the wheel fork by pulling it down
3. distribute the spacers as desired – in case of first time assembly, the rings must be
spread out equally above and below the frame
4. replace the cotter pin

6.1 Vehicle operation
The operating elements of the vehicle shown below are required for working with the leaf
vacuum machine.
Please read the operating handbook of the vehicle manufacturer for the exact functioning
of the operating elements.
6.2 Operation of the working device
•by pressing the red buttons on the middle console, the device can be lifted/lowered.
•by briefly pressing the “Lower” button a lowering pulse is initiated
•the device can be completely lowered by a longer press on the “Lower” button
6.2.1 Side brush/pick-up shaft
•the side brush can be set in the desired work setting by using the screws
•the required rotational speed for the side brush/pick-up shaft can be set with the throttle
valve
•the rotational speed of the brushes is the same as that of the pick-up shaft
•when setting the side brush, keep in mind that it must be positioned with a slight front and
right tilt so that leaves and litter are not simply tossed around in a circle
and are instead released after half a turn and picked up by the pick-up shaft
•in the travel direction, this vaguely represents one work cycle of the brush
on the ground, between 12 and 3 o'clock
•the brush starts simultaneously with the pick-up shaft
