Product description
Holms SL is designed for smaller carriers, e.g. loaders
and tractors, front or rear-mounted. This sweeper roller is
powered by two direct-acting hydraulic motors; these are
designed for a flow of between 40 and 130 l/min.
The suspension of the sweeper roller ensures constant
and even pressure against the surface. This minimises
brush wear and ensures responsiveness to inclines and
uneven surfaces.
Standard model
The standard-design sweeper roller has a polythene
(plastic) splash guard.
Extra equipment
There is a range of extra equipment available for SL:
• Sprinkler system with 400 or 600-litre tank, complete
with pump, tank and spraying ramp.
Electrohydraulic angling allows turning of the roller
while on the move, and the machine only requires a
single hydraulic function.
• Lateral movement enables the roller to be moved to
the side hydraulically ±0.7 m.
• Lorry attachment with built-in lifting function for
VV-85, DIN plate or equivalent.
• Various types of brush, conventional or Dusk design,
steel or plastic.
• Universal electrical cabling.
• SL-City (Extra equipment).
SL-City, larger mud flap with rubber sheet for
improved splash protection. Can be set to three
different heights according to the amount of brush
wear. It is also possible to hook the rubber sheet in
place if it is not meant to stop splashes.
• SL-CitySalt (Optional accessory).
Brine spreading during the frost/winter season. Read
more under Operating instructions – SL-Citysalt.

Operating instructions
Connection to carrier using standard attachments
1. Connect the sweeper to the carrier's machine
attachment. See Instruction Manual for the carrier in
question.
2. Connect the power hoses' quick couplings to the third
function's hydraulic outlet or to the hydraulic motor
circuit on the carrier.
3. Connect the quick couplings on the angling cylinder
to the fourth function hydraulic outlet. (If the sweeper
roller is equipped with electrohydraulic angling,
connect the cabling to the carrier. For electrical
connection, see electrical diagram in spare parts
catalogue.)
4. Start the sweeper roller by moving the lever for the
third hydraulic function to its locked position, or
activate the hydraulic motor circuit.
5. Check that the sweeper roller is rotating in the right
direction. If the sweeper roller is rotating in the wrong
direction in the locked position, change the locked
position or change the quick couplings for the third
hydraulic function.
Connection to carrier without own lifting device
1. Connect both lifting cylinder hoses to a double-acting
hydraulic function, set connection pin in position, see
figure 6.
2. Lift up the attachment and run the vehicle forward
towards the machine. Attach the sweeper to the
carrier.
3. Lift the sweeper and remove the pin from the
connection device. Remove the supports.
4. Check the tilt angle (the correct tilt angle is when the
centre attachment on the sweeper roller is vertical.
(Check with a spirit level, if necessary). Adjust the tilt
Check that the machine is secured to the carrier.
Warning! Check that there is no one present within
the risk area (15 m radius around the machine) in
order to prevent injury from objects thrown up by
the roller.

angle by means of washers between gate and rear
attachment (see figure 7 or use adjusting screws if the
machine is equipped with a tilt device.
5. Connect the power hoses' quick couplings to a
double-acting hydraulic outlet or to the hydraulic
motor circuit on the carrier.
6. Connect the quick couplings on the angling cylinder
to a double-acting hydraulic outlet. (Or, if the
sweeper roller is equipped with electrohydraulic
angling, connect the cabling to the carrier).
7. Start the sweeper roller by activating the hydraulic
motor circuit.
8. Check that the sweeper roller is rotating in the right
direction. If the sweeper roller is rotating in the wrong
direction in the locked position, change the locked
position or change the quick couplings for the
hydraulic motor function.
Operator settings
The following operator settings must be selected:
• vertical position and tilt (see below)
• ground pressure, see “Setting the ground pressure” on
page 17.
Adjusting the height and tilt of the sweeper roller
1. Lift the sweeper roller. Raise and secure the supports
in the operating position (see figure 8).
2. Slowly lower the sweeper roller until the height
indicator’s yellow markings line up (see figure 9).
3. Tilt the sweeper roller until the tilt indicator’s yellow
markings line up (see figure 10).
4. Readjust the height where appropriate as per item 2.
5. Start the sweeper roller via the third hydraulic
function or via the hydraulic motor circuit.
When angling a sweeper roller using
electrohydraulic angling, the roller must be in
contact with the ground.

Setting the ground pressure
The ground pressure for the sweeper roller can be
adjusted to suit different conditions. This is done using
the adjustment lever (figure 11) when the machine is in
parking mode(figure 12).
1. Adjust the height and tilt of the sweeper roller.
2. Allow the sweeper roller to rotate for a while against
the ground.
3. Then measure the width of the strip that has been
swept clean. This should normally be approx. 10-20
cm.
4. Reduce the ground pressure by lowering the
adjustment lever.
5. Increase the ground pressure by raising the
adjustment lever (figure 11).
Do not use the carrier’s lifting or tilt function to
adjust the ground pressure.
Always turn the sweeper roller off properly before
making any adjustments.
Lower the attachment, to relieve pressure on the
springs, before making any adjustments.

Operation
Settings for sweeping will normally be as per section
“Adjusting the height and tilt of the sweeper roller” on
page 16. The yellow markings on the height indicator and
the tilt indicator must line up. In this position the loader
attachment is vertical to the ground. The sweeper roller
then applies even pressure along its entire width (see
figure 13).
If greater pressure is required on either side of the roller
or if the roller has become unevenly worn, this can be
adjusted by altering the tilt. Tilting the sweeper
backwards produces greater pressure on the side of the
sweeper roller angled towards the carrier (see figure 14).
Tilting the sweeper forwards produces greater pressure
on the side of the sweeper roller angled away from the
carrier (see figure 15).
When transported on the carrier, the sweeper roller must
be in the tilted up position.
Disconnection from carrier when using standard
attachments
1. Release the machine attachment's lock pins before
lowering the sweeper roller to the ground in order to
prevent damage to the counterbalancing system.
2. Lower and secure the supports in parking position.
3. Lower the sweeper roller to the ground.
4. Release the quick couplings for the third and fourth
function hydraulic outlet or the hydraulic motor
circuit and electrical cabling.
Disconnection from carrier without own lifting device
Do not use the carrier’s lifting function to adjust
the ground pressure. Use the adjustment lever
instead (see figure 11 on page 17).
The brush will become deformed if the sweeper
roller is not parked on the supports.
Before disconnection the roller must be in line
with the angling cylinder and any lateral
movement.

1. Position the supports in the parking position (see
figure 16). Set the connection device pin in the lifting
position.
2. Gently lower the sweeper roller to the ground, release
the sweeper roller from the carrier and back up
slightly.
3. Lower the sweeper roller gate to the lowest position
using the lifting cylinder.
4. Release the quick couplings and any electrical
cabling.
Sprinkler system (extra equipment)
The pump must not be run when dry, i.e. once the water
has been used up the pump must be switched off.
The machine is equipped with a water filter, located by
the pump, to prevent dirt from getting into the system.
The filter can be flushed clean and reused. It must be in
place when the tank is filled, otherwise there is a risk of
the pump and water system being damaged.
When there is a risk of freezing, empty the water from the
water tank, water pump and associated hoses. The easiest
thing is to empty the tank first and then run the pump dry
for 20-30 seconds. When emptying the tank, disconnect
the hose coupling from the tank.
SL-Citysalt (extra equipment)
To achieve 8 grams of 100% NaCl per square metre, the
equipment must be free of snow after the sweeper roller
and not exceed an operating speed of more than 10 kph.
Salt spreading with brine should be done at temperatures
above -7 degrees Celsius.
When transport to the work site takes place at
temperatures below -5 degrees Celsius, the sprinkler
function should be turned on every 3–5 minutes for a
short period.
If the jets and system freeze up, the best way to defrost
them is either with water or by storing the equipment
somewhere warmer than 0 degrees Celsius.
The brush will become deformed if the sweeper is
not parked on the supports.
Make sure that the system is depressurised before
releasing the quick couplings.
16.Supports in parking

SL

When a salt solution is used in the water tank, a
desalination process should be performed at regular
intervals; this means pouring in fresh water and running
it through the sprinkler system.
The sprinkler function should not be stored somewhere it
can freeze up.
When the salt spreading season has come to an end, the
system should be rinsed through with fresh water and
then drained. When using the dust control function, other
jets should be used (read more about this on the Service
and maintenance tab).
Remember to rinse off the sweeper roller with fresh water
at the end of shifts to reduce the amount of corrosion.
