Product Description
Holms SU is a front-mounted, pick-up sweeper for small
carriers, e.g. loaders and tractors. The roller is driven by
a direct-acting hydraulic motor, which is intended for a
flow of hydraulic oil of between 30-80 litres/min.
The suspension of the roller brush ensures a constant and
uniformly distributed contact pressure to the surface.
This minimises brush wear and contact with incline and
uneven surfaces.
In the standard version, Holms SU is fitted with a water
tank and an electric water pump. The machine’s
attachment hooks are secured with screws, whichenables
lateral displacement and also simplifies switching
between different carriers.

Operating instructions
Connection to carrier
1. Connect the sweeper to the carrier by tilting the ma-
chine attachment forwards, couple in the hook part,
and then lift and tilt back. The machine must then be
locked. See Instruction Manual for respective carrier.
2. Connect the quick-couplings on the drive hoses to the
third function hydraulic outlet, or to the hydraulic
motor circuit on the carrier.
3. Connect the electric cable on the water pump to the
carrier. The socket must be rated for at least
10 Ampere.
4. Start the roller brush 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, see figure 3 If the sweeper roller is rotating
in the wrong direction in the locked position, change
the locked position for the lever or change the quick-
couplings for the third hydraulic function.
Adjusting the height and tilting of the machine, sweeper
without support wheels
1. Lift up the sweeper.
2. Tilt the sweeper until the tilt indicator’s yellow
markings line up, see figure 4.
3. Slowly lower the sweeper until the container is 5-
10 cm above the ground, i.e. approximately when the
rubber lips reach the ground, see figure 5.
4. Readjust the tilt where appropriate as per item 2.
It is extremely important that the hydraulic
couplings are clean. Allowing dirt into the
hydraulic system would severely impair sweeper
functionality.
When running the machine on uneven surfaces it
may be necessary to temporarily lift it to avoid
contact between the ground and the refuse container.
When operating in sensitive environments, the
sweeper can temporarily be tilted forward slightly.
This reduces any forward spraying of stones.

Adjusting the height and tilt of the machine, sweeper with
support wheels
1. Lift the sweeper.
2. Tilt until the sweeper is horizontal.
3. Lower the sweeper slowly until the yellow markings
on the support wheel set, see figure 6, line up.
4. Readjust the tilt where appropriate as per item 2.
Adjusting the height and tilt of the machine,
sweeper with one support wheel
1. Lift the sweeper.
2. Tilt the sweeper until the tilt indicator’s yellow
markings line up, see figure 4 on page 12.
3. Lower the sweeper slowly until the support wheel
comes into contact with the ground, see figure 7.
4. Readjust the tilt if necessary.

with side brushes, see “Operation” on page 14.
Disconnection from carrier
1. Release the hydraulic quick-couplings and electric
cable.
2. Release the machine attachment lock pins, and
carefully lower the machine to the ground. This is
important, otherwise the sweeper may be damaged.
3. When the machine reaches the ground, tilt forward
and then back to release the hooks.
Sprinkler
The pump must not be run when dry, i.e. once the water
has been used up the pump must be switched off.
Themachine isequippedwithtwo waterfiltersto prevent
dirt getting into the system. One filter sits in the tank
Operate carefully in transport position on uneven
surfaces, to avoid exposing the sweeper to undue
strain.

fillinghole,whilst theother filterislocatedon thesuction
side of the pump. The filters can be flushed clean and
reused. NB The filters must be in position when the tank
is filled, otherwise there is a danger that the pump and
water system will be damaged.
Where there is a risk of freezing, empty the water from
the water tank, water pump and attendant hoses. The
easiest thing is to empty the tank first and then run the
pump dry for 20-30 seconds. When emptying the tank,
the hose on the tank can be disconnected using a quick-
coupling.
Side brush (accessory)
Holms SU can be fitted with a side brush for more
efficient sweeping up against kerbs, etc. It can be fitted
on the right or left side.
Operation
The side brush is lowered by removing pin A and lifting
the brush off its mounting B (figure 9). Refit pin A. It is
very important to refit pin A as it functions as a stop.
The side brush must always be in its upper, locked
position during all transportation and emptying.
This is because the side brush can be damaged if it
is not locked.

Maintenance
After operation
• Wash the sweeper. This will increase its service life
and make it easier to detect any leakage or other
faults.
• Inspect the machine and make sure that the hoses,
rubber housings and the machine body are not
damaged. Also check for any oil leakage.
• Fill up the 6 lubrication points.
Replacing the brush
Tools
• allen key
• socket wrench
• key ring
• screwdriver
• rubber mallet
Carefully lower down the container to the ground.
Removing the roller brush
1. Drain the water tank by disconnecting the quick
coupling at the tank, see figure 10. Then disconnect
the straps (A figure 11) and lift the water tank out.
2. Remove the lifting stops on both the right and left
side. See C figure 11.
3. Release the front attachments on the slewing brackets
on both sides. See D figure 11.
Note that only the screws are released from the
outside,andthat theslewingbrackets themselvesmay
be left in position in their clamp plates, see figure 12.
4. Carefully lift up the machine to allow the motor to be
pulled out from the side. See figure 12.
5. Lift up the machine and remove the roller.
If the machine is lifted up too high before the
motor unit has been pulled out, the roller can be
left hanging from the hydraulic hoses and there is
a risk of damaging them.

Replacing the brush
1. Release the three tension springs and remove the
roller brush’s end ring, see figure 13.
2. Pull off the brush and spacer rings. This is most easily
done by hanging up the roller vertically in an
overhead crane or suchlike.
3. Check the core for damage.
4. Lift up the brush core with the bearing shaft facing
downwards on a pair of wooden blocks or suchlike.
This is to prevent damaging the shaft and slewing
brackets.
5. Fit a brush with the brush ring “pins” in the space
between the three square sections.
6. Fit a spacer ring.
7. Fit alternating brush rings and spacer rings. Note that
the brush ring “carrier pins” should be placed at
approximately equal distances between the three
square sections. This is so that no single section will
be exposed to all the strain from the brushes.
8. To “cover” the entire core it may be necessary to use
double brushes without spacer ring on the end so that
the right length will be obtained.
9. Refit the end ring using the three tension springs. See
figure 12.

Fitting the roller brush
1. Lift the machine and roll in the brush. Lower the
machine. See figure 14.
2. Push in the motor unit and place the motor end
slewing brackets up in the container.
3. Carefully lower down the machine to the ground.
4. Fit the motor end slewing brackets to the chassis.
5. Put the singleslewing bracket in position (in opposite
side to the motor end) and fit it in the chassis.
6. Refit the slewing bracket stops, water tank, straps and
hose to the water tank.
Replacing the side brush
Unscrew the four nuts and lower the brush.Refit in the
reverse order, see figure 15.
Assembly
When removing the bearing pins they must be driven out
in the direction of the arrows, see figure 16.
This is because the holes for the pins are rifled to prevent
them rotating.
Make sure that the slewing brackets are not
jammed when the machine is put on the ground.
Always use locktite on the screws.

Other service
Lubrication points
Lubricate the machine's five lubrication points when
changing brush, see figure 17 and figure 18. Also
lubricate the lubrication points prior to long-term storage.
Fitting the hydraulic hoses
If the hydraulic hoses have been disconnected, it is
essential that they are refitted correctly.
• The hoses are fitted at an angle of 45° to the ground
• The hoses must then follow the inside of the chassis.
See figure 19.
Fitting the bearings
The machine’s bearings are made of maintenance-free
material. They must, however, be greased before being
refitted.
