Handling and assembly
Noise Sweepers produced by GMR maskiner are extremely quiet. The noise
level depends on the type of tractor and is typically between 74 and
85 dB (A). The noise level is indicated in the tractor’s user manual.
Handling
Fig. 1
Hearing protectors If the tractor operator is disturbed by noise, we recommend the use of
hearing protectors or similar.
All sweepers are equipped with 2 support legs. When the support legs
are tted, the sweeper remains in a stable position when disconnected.
Use a crane to move, transport or carry out maintenance.
The crane must always lift in the centre of the main beam.
See Fig. 1.
CAUTION
Risk of damage to brushes/brush rolls
Make sure that the support legs are tted when the
machine is being lifted with the crane.
WARNING
Safety zone
When lifting the machine, everyone must keep a
distance of min. 3 metres from the machine as there
may be unintended movements.
If the machine is lifted by crane for maintenance, the sweeper must be
safely supported before work is carried out under the machine.

Mounting on the tractor
Before mounting The machine is delivered assembled and tested from the factory.
Before mounting the machine, proceed as follows:
• Ensure that the sweeper is standing on a rm and level surface.
• Remove the plastic protection. Remove the PTO shaft on
mechanical models.
• Check that the rpm and direction stated on the main frame is
correct for the tractor in question. If not, you must contact your
dealer!
• The machine is lled with oil at the factory. Check the oil level,
which must be in the middle of the gears. If the oil level is too low,
top up with 80W-90 gear oil.
To t the sweeper on the tractor, manoeuvre the tractor so that it is at
right angles to the machine.
NOTE: Remember to ensure that the sweeper uses the same coupling
system as your tractor.
A-frame system
Fig. 2
• Lower the male section of the tractor and drive it under the female
section. See Fig. 2.
• Lift the male section and click the locking system in place.
• Lift the machine slightly.
• Shut off the tractor engine.
• Remove the support legs or turn them so they are located over the
brush guard.
• Fit the PTO shaft. Both forks must click into place. Attach the safety
chains (mechanical machines only).
• Connect the hydraulic hoses, which drive the sweeper, to the trac-
tor using the snap couplings (hydraulic machines only). Check the
snap couplings for impurities. Clean if necessary.
• Connect the hydraulic hoses, which drive the sweeper’s swing
function, to the tractor using the snap couplings.
• Check the snap couplings for impurities. Clean if necessary.

Mounting on the tractor
3-point tractor hitch
• Lower the hitch arms.
• Drive at right angles up to the machine.
• Shut off the tractor engine.
• Connect the hitch arms to the machine.
• Connect the top bar to the sweeper.
• Connect the PTO to the tractor. Check that the locking pin in both
forks clicks into place.
• Fit the safety chains (mechanical machines only).
• Connect the hydraulic hoses, which drive the sweeper, to the
tractor using the snap couplings (hydraulic machines only).
CAUTION
Risk of engine explosion
Check that the hydraulic couplings are of the correct
type and that they are correctly engaged. Incorrect
connection can cause the engine to explode.
WARNING
Safety zone
Never manoeuvre the tractor hitch if there are people
in the vicinity.
• Connect the hydraulic hoses, which drive the sweeper’s swing
function, to the tractor using the snap couplings.

Mounting on the tractor
CAUTION
Damage to machinery or attachments
Follow the instructions in the PTO shaft user manual.
If you are in any doubt, contact the dealer.
CAUTION
Hydraulic hoses
Take care to connect the hydraulic hoses to the
tractor so that they cannot come into contact with
moving parts.
NOTE
Shortening the hoses
The hydraulic hoses are supplied in standard lengths.
If the hoses need to be shortened, this should be
done by the dealer.
Other hitch systems If the hitch system on your tractor is different to that described in the
user manual, follow the tractor user manual to mount the sweeper.
If the sweeper is not compatible with your tractor, please contact the
dealer.

Basic settings
Top bar position
Pos. 1
Pos. 2
In order to lift the machine properly, the top bar must be tted so that
the top bar eye on the tractor (pos.1) is mounted lower than the top bar
eye on the sweeper (pos. 2).
If this is not possible, you can order a special bracket to raise the top
point of the sweeper. The bracket can be ordered from your dealer.
NOTE
Risk of unnecessary wear
If the top bar is mounted differently than described,
the sweeper will tip forward when raised/lowered,
resulting in unnecessary wear on the PTO shaft.
Adjusting the top bar Adjust the top bar to achieve best sweeping results and minimum wear
on the brushes. The pivot joint between the mounting frame and main
beam must be positioned vertically in the working position. The pivot
joint moves when the sweeper is swung from one side to the other.

Controlling the swing
function
• Start the tractor.
• Swing the sweeper from side to side. If this is the rst time that the
sweeper has been tted, swing the machine 4-6 times to empty any
air pockets from the cylinder and hoses.
• Make sure that the machine swings freely and unhindered.
Adjusting the brush guard The brush guard is set at the factory to a distance of 30-60 mm
between the brush and guard.
If the brushes begin to wear, adjust the guard straps to maintain this
distance.

Adjusting brush pressure The brush pressure determines how much force the machine uses to
sweep.
In the following section, the term “brush line” is used. This is the line which
is visible when the brushes are rotating. The brush line is located 0-100
mm above the ground and can be seen across the entire brush width.
The brush line marks the point at which the brushes have contact with
the ground. The brushes bend backwards and then swing back into
place as they lose contact with the ground.
Front view of brush roll
Type: FF/LA, FF/LSA,
FF/MA, HF/MA, FF/PA, HF/
PA, FF/SP, FF/SPS and
HF/SP
Adjust brush pressure via the two bolts mounted on the right and left
side panel respectively (see Figure “Bolt used to adjust brush pressure“
on page 18).
Type: HF/LF and HF/MF To adjust brush pressure, adjust the spindle handles on the support
wheels.
Set the brush pressure so that the brushes almost lose contact with the
ground.
CAUTION
Damage to brushes, wheel and wheel fork
Never use the top bar to adjust brush pressure.
If you do, the turning point will no longer be vertical,
causing damage to the brushes, wheel and wheel
fork due to incorrect loading.

• Lower the brush line (see “Indstilling af børstetryk”, page 17).
• Check that the brush line is the same across the machine width. If
this is not the case, the two bolts (Point 1) are not aligned.
Repeat points 1 to 4.
Adjusting brush pressure
(Point 4):
The tractor operator swings the sweeper to one side. Check the brush
line again. If it is not the same across the entire machine width, the
pivot joint is not vertical. The top bar should be adjusted.
Repeat points 1-5.
The closer the brush line is to the ground, the lower the brush pressure.
Adjusting brush pressure
(Point 5):
CAUTION
Damage to brush and machine parts
Brush pressure must not be set so hard that the brush
line is more than 100 mm above the ground.
WARNING
Safety zone
When releasing brush pressure once the machine
is operating, always maintain a safe distance of
min. 5 m from the machine.
