Important safety aspects to take into consideration• Make sure that the tractor/loader can carry the equivalent tool type and weight.
• Make sure that for this sweeper the carrier has a suitable hydraulic oil flow.
• Make sure that no unauthorised persons are loitering in the machine’s working area when working with the machine or carrying out servicing.
• Always use the dust covers for the quick-couplings when the machine is disconnected, to prevent dirt getting into the hydraulic system.
SafetyThis instruction manual is intended to be used as a guide for the correct use and maintenance of the machine. Study the manual carefully before starting and operating the machine and before any preventive maintenance is carried out. A lot of time has been spent on designing and manufacturing the machine so that it will be as efficient and safe as possible, all of which will be of little use if you do not read, understand and follow the instructions. Familiarise yourself with the product and all the instructions, and keep the instruction manual safe so that it is always readily at hand when using the machine.

The carrier is suitable for use with the machine (hydraulic oil flow, stability, etc.).
Product descriptionHolms SP is an extremely robust sweeper roller designed for front-mounting on loaders. The area of application is sweeping of “heavy” rubbish such as waste: minerals, sawmill waste, etc. The sweeper roller is driven by two direct-acting hydraulic motors housed inside the brush core and requires an oil flow of 80-350 litres per minute.
Standard model
Holms SP consists of a roller brush suspended from a central section that can be angled. Splash guard comes as standard. The machine is supplied with screw-mounted attachment hooks. The suspension of the sweeper roller ensures a constant and uniformly distributed brush pressure to the ground.
Optional extras
• Sprinkler system consisting of water tank (240 litres), electric pump and spraying bar.
When loading and unloading, lift the machine using the marked lifting eyes. Please note that these differ depending on whether or not your machine is equipped with a sprinkler system. See figure 4 and figure 5.
Storage
Park on supports to avoid damage to the brush.
When storing, remember to drain the sprinkler system. Make sure that the machine is lubricated; there are five lubrication points. See figure 10 on page 16.
Use approved lifting devices only.
When transporting the machine, use the marked loops to secure the machine during transit.

Operating instructionsNB! TO PREVENT THE SWEEPER’S HYDRAULIC MOTORS BEING DAMAGED BY PRESSURE PEAKS, THE LOADER’S ENGINE REVS MUST BE REDUCED BEFORE THE SWEEPER IS TURNED OFF.
Connection to carrier
1. Connect the sweeper roller to the loader’s machine attachment. See the instruction manual for the loader in question.
2. Connect the drive hoses to the third hydraulic function outlet or to the hydraulic motor circuit on the loader.
Settings
Adjustment of the sweeper roller for height and tilt
1. Lift the machine up off the ground.
2. Lift and lock the supports in the operating position (see figure 6).
3. Slowly lower the sweeper roller so that the height indicator’s yellow markings line up (see figure 7).
4. Tilt until the machine’s yellow-marked tilt indicators are lined up (see figure 7). Readjust the height where appropriate.
Adjusting ground pressure
The ground pressure can be adjusted to suit different con-ditions. Adjustments are made by stretching or loosening the springs that hold the lower slewing brackets. The ground pressure on the left side of the sweeper roller (viewed from the carrier) is increased by turning the spring tensioner clockwise, and reduced by turning it an-ti-clockwise (see figure 8). On the right side of the sweep-er roller, the spring tensioner is turned anti-clockwise to increase the ground pressure and clockwise to reduce it.
NB! Tighten or loosen both sides equally when making an adjustment.
Check that the machine is secured to the carrier.
Check before connecting that the hydraulic couplings are properly clean, in order to avoid operating problems due to dirty oil.

8.Adjusting ground pressure (left side of sweeper roller viewed from carrier)
1. Lift the sweeper roller. Open up and secure the support in the operating position.
2. Lower the sweeper roller to ground level (or onto a trestle), so that the sweeper roller’s lower slewing brackets are in their top position and the springs are minimally loaded.
3. See figure 8 on page 13 – fit a ½" ratchet handle into the square hole in the centre of the spring tensioner.
4. Loosen the nut on the locking screw. Hold the ratchet handle in place while you remove the locking screw. Turn the ratchet handle clockwise or anti-clockwise, depending on the desired adjustment. Adjust the ground pressure no more than 165° (corresponds to a maximum of 3 holes in the outer tension plate and one step on the inner tension plate).
5. Refit the locking screw and locking nut. Check that the nut is securely tightened.
OperationNormally the height and tilt indicators must be lined up during operation. If you want to increase or reduce the pressure on one side with the roller in an angled position, this can be done by using the tilt function. This is useful when you are sweeping pavements, for example, and have two wheels on the pavement and two on the road, or when the roller brush is unevenly worn. Tilting the sweeper roller forwards increases the ground pressure on the side of the sweeper roller that is angled away from the carrier.
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.
Be careful. There is a risk of crushing when adjusting ground pressure!
In order to be able to angle the roller, the roller brush must be in contact with the ground.
Disconnection from carrier
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. Close down and lock the supports in the parking position (see figure 9).
3. Lower the sweeper roller to the ground.
4. Release the hydraulic hoses from the carrier, fit the plastic covers over the quick-couplings to protect against dirt, and disconnect the electrical connection to the water pump (if the sweeper roller is equipped with a sprinkler system). NB! The brush becomes deformed if the roller is not parked on the supports.
Sprinkler system (optional extra)
Sweeper rollers with a sprinkler system are equipped with two water filters to prevent dirt getting in. One filter sits in the tank filling hole, whilst the other filter is located on the pump connection. Check the filters at regular intervals and rinse clean as required. The filters must always be in place to avoid damage to the pump or blockages in the spray nozzles.
The pump must not be run for long periods when dry, i.e. once the water has been used up the pump must be switched off.
When there is a risk of freezing, the tank, pump and hoses must be emptied of water. When the tank is empty, run the pump for a further 30 seconds or so to ensure that the pump is also emptied. The easiest way to empty the tank is to release the hose connections to the tank.
Wash the sweeper roller. This prolongs its service life and makes it easier to detect any leakage or other faults.
Inspect the machine and check that the hoses, brush guards, springs and machine body are not damaged. Check also for any oil leakage.
Lubrication
When replacing the brush, lubricate all lubricating nipples. Clean the nipple and lubricate until grease appears. See figure 10.
Replacement of brush
It is easiest to replace the brush if the roller brush is attached to the carrier. Before starting to replace the brush, lower the roller brush to the ground (parking supports must be in operating position).
Removing the roller brush
1. Start by removing the moving parts of the height indicator.
2. Loosen the upper slewing bracket by pulling the pin out. The roller brush will now move forwards/downwards.
3. Remove the lower slewing bracket by loosening the two screws (see figure 11). NB! Requires considerable force.
4. Unfold the roller brush from the bar tube and remove the drive unit from the brush core.
5. Remove the entire roller brush from the carrier housing on the opposite side.
Replacement of brush
1. Loosen the screws on the clamping rings at both ends of the roller brush and remove them (see figure 12).
2. Insert shackles into both holes at one end of the brush core and secure a lifting loop in the shackles.
Risk of crushing! The lower slewing bracket is heavily spring-loaded and flies up unless you hold it down firmly.
