The Nilsk Outdoor suction sweeper is eective
everywhere – on paths and pavements, verges, driveways,
outdoor and indoor parking areas, etc. Two optional side
brushes increase the suction sweeper’s clearing width to
2,100 mm .
Dust is cleaned away in two stages using the suction
sweeper. Two water-sprayers dampen dust before it is
sucked up. The well-known Nilsk Outdoor rotary lter
system binds even the nest of dust to the water inside
the hopper. A robust and quiet unit, the suction sweeper is
available with 2, 3 and 4 brushes.
Operator’s Manual - City Ranger 2250 - Suction sweeper
Emptying the collection tank is easy and done from the
comfort of the cab seat.
The suction sweeper can be attached or detached quickly
and easily, using the specially designed moveable frame.
The brushes and hopper can be attached to the frame. This
handy design feature means they can be smartly stored
away too!
Adjusting brush speeds
Brush speed can be controlled in dry conditions, slowing
the brushes to prevent dust spreading.

General information
1.1 Safety
Avoid roll-overs
Do not drive the machine in a place where it
!
can slide, tip or roll. Do not drive on slopes
with an incline of more than 10°. (Picture 1)
Tyre pressure
The tyre pressure must be checked and adjusted to 1.5 bar
(22 psi) when the suction sweeper is attached. Lower tyre
pressure increases the risk of roll-overs.
Emptying the hopper
Before emptying the hopper, make sure that:
A) The machine is rmly placed on a level surface and is not
“angled”
B) That there is sucient space for the open back cover.
Make sure the hopper is secured
Check the hopper is rmly attached to the

Attention
As it is articulated, the rear end of the machine swings out
when turning. Make sure that no one is near the machine
while it is in use as there is a danger of crushing.
machine. (Picture 2)
Prevent people from standing close to
the suction sweeper
Make sure there is no one close to the
machine when it is in use.

Attention
The suction sweeper must not be used if the water-sprayer
in the hopper is not working.
Stop the turbine immediately if there is imbalance/
vibration in the lter or in the turbine.
A low-level switch has been tted which automatically
stops the water pump if the water tank is empty.
A lamp lights up when there is water in the tank. The lamp

Do not drive the machine in a place where it can slide, tip
or roll. Do not drive on slopes with an incline of more than
10°. (Picture 1)

The transport lock prevents the attachment from lowering
during transport.
How to use the transport lock: Move the handle to the
uppermost position. Lift the A-frame by moving the
joystick up. As the A-frame lifts, the transport lock is
automatically activated. (Picture 2)

2.7 Emptying the hopper
The hopper can empty directly onto the ground or tip into
a container.
Tipping height 130 cm.
Attention
Before emptying the hopper, make sure that:
A) The machine is on a level surface, and that it is not
“angled”.
B) That there is sucient space for the opened back cover.
1. STOP the front and rear PTO. (Picture 1)
2. Drive to the nearest disposal area.

3. Begin emptying by using the lower joystick to tip the
hopper. (Picture 2)
4. Lower the joystick once the hopper is empty.
(the hopper will move back to its normal position)
Release the handle when the hopper is back in position.
The hopper is tted with a hose-break valve, which will
close if the hopper lowers too quickly. If this happens, raise
the hopper a little again and then lower it slowly.
(Pi cture 3)
Attention
The rear hatch must not be opened until suction has
ceased. Otherwise there is a risk of personal injury. The
suction continues to run for approx. 15 s after the turbine
has been switched o (PTO rear).
There is a risk of crushing while the hopper is being
emptied.
Make sure the hopper is completely lowered after
emptying!

The water in the hopper can be emptied by unscrewing
the drain plug. (Picture 1)
2.9 Protect the suction sweeper against ice during the winter
1. Pouring a solution of water and anti-freeze into the
water tank – the same solution as if protecting a sprinkler
system against ice.
2. Turning the turbine and water supply to the front
brushes on, the liquid runs through the whole system and
protects it against ice.
3. Alternative, completely empty the water in the tank and
the rest of the system.

2.10 Adjustment
1. Adjusting brushes
Adjust the brushes using the nose wheel. Adjust the
brushes so that they precisely brush the ground to give a
maximum clearing width, with half of the brush bristles
touching the ground at any given time. (Picture 1)
2. Adjusting the vacuum nozzle
Adjust the distance between the surface and vacuum
nozzle using the height-adjustment xture. (Picture 2)
With the nose wheel screwed all the way down, the
distance between the hydraulic motor and the ground
is 95 mm. (Picture 3) This adjustment also aects the
coupling between the front brushes and the machine.
Check that the vacuum hose is tightly connected to the
vacuum nozzle.

2.11 High-pressure cleaner (optional
equipment)
The high-pressure cleaner is stored in a hollow space
behind the hopper. To gain access to the high-pressure
cleaner, pump and lter, the hopper must be tipped as far
back as possible. (Picture 1 + 2)
The spray lance, hose and switch valve are located on the
back of the machine. (Picture 3)
The high-pressure cleaner runs on the same hydraulic
connector as the suc tion tank turbine. To switch between
turbine and high-pressure cleaner, activate the switch
valve on the back of the hopper.

To start the high-pressure cleaner
1. Turn the switch valve to the left
(to run the high-p ressure cleaner).
(Pic tur e 1)
2. Start the hydr aulic system ”manual operation”
(see sect ion 2.6).
The machine should run at about 2,000 rpm.
3. Remove the spray lance and hoses from the hose rac k. Clean as
required.
4. To stop the high-pressure cleaner, turn the switch valve to the
right. (Picture 1)
5. Release the pressure in the water hose by activating the spray
lance.
6. Roll the hose tightly in a cloc kwise direction and return the spray
lance to its holder. It is important that the hose is rolled tightly so
that it ts snugly into the hose holder.
1
Switch valve
NB
Excessive rpm will not cause any noticeable
increase in water pressure as the ow of oil to the
high-pressure pump is regulated.
The water pump is tted with a bypass function to ensure that
the pump does not overheat in ”neutral”, when the high-pressure
cleaner is not using water. We recommend that you do not run the
high-pressure cleaner in ”neutral” for more than 10 minutes at a
time
Important
The water pump must never run when the water
tank is empty. If the water pump runs for more
than 1 min. without water, the pump will be
damaged and will fail relatively quickly.
Warning
When you turn the switch valve back to ”run
turbine”, the suction system immediately restar ts.

3.1 Cleaning/replacing lter system and
turbine
Daily cleaning and maintenance will extend the lifetime of both the
machine and the attachment.
Clean the suc tion sweeper with water af ter use. Avoid high pressure
cleaning of the snap couplings.
Clean the snap couplings with a cloth. (Picture 1)
Cleaning/replacing lter system and turbine
Attention
In case of imbalance in the lter or turbine, the machine must be
stopped immediately to prevent vibration damage.
Checking the lter and turbine daily
Dirt can c ause imbalance in the rotar y lter and turbine. It must
be removed imme diately! Give special attention to the lter and
turbine while the machine is operating in dicult conditions.
Cleaning the rotary lter and turbine
1. To remove the turbine inspection hatc h, loosen the lever on the
hopper. Rinse the turbine clean with water, preferably using the
high-pressure cleaner. (Picture 2)
Service and maintenance

2. If the turbine is very soiled, remove the rotary lter and rotary
lter grill to give better acce ss for cleaning the turbine.
(Pic ture 3+ 4)
3. Check for dir t on the turbine and clean. (Picture 4)
4. Flush the turbine until it is clean. A high-pressure cleaner is
recommended for this purpose.
5. Attach the rot ary lter grill and rotar y lter. Bolt should be
tightened to 45 Nm of torque.
If the rotar y lter cannot be cleaned or is worn, it should be replaced.
New lters can be ordered f rom an authorised Nilsk Outdoor
dis trib utor.
