1. Scope of Application
(The digits in text correspond to the item numbers on spare part list.)
- This machine is approved for use as a foliage and
garden waste vacuum (by converting the machine into a foliage blower) as described in these
operating instructions.
- The machine must not be used for any other purpose. The manufacturer shall not be liable for
damage resulting from improper use of the equipment. In such cases the user shall bear sole responsibility.
- Proper use includes observation of the operating,
maintenance and repair instructions given by the
manufacturer.
- Only personnel who are familiar with the machine
and possible dangers should be allowed to operate or repair the machine.

2. Description
The machine comes pre-assembled except for the
foliage bag (8) and the suction nozzle (25/32). The
suction nozzle and bag should be fitted as shown in
Fig. 1.
The vacuum body has 4 wheels (9/36/46a+b/47);
hard rubber steering wheels at the front (9/47) to
resist damage by thorns, cushion tyred wheels at
the rear (36/46).
The drive consists of a 2.6 or 3.75 kW Honda petrol
engine. Model LS 3500 does not have a wheel
drive, model LS 5000 features a wheel drive. The
working width is 80 cm. A hand lever (27) is provided on the steering handle to adjust the suction
height of the nozzle (3).
The machine can be converted into a foliage blower
(see 4. Operation for further details).
For further technical data please refer to the table in
Section 7.
3. Safety Instructions
1. Always check machine for roadworthiness and
operating safety prior to use.
2. Observe all valid safety and accident prevention regulations in addition to these operating
instructions.
3. Read and understand these operating and
maintenance instructions and make sure that
you are familiar with the control elements and
their proper use.
4. Do not allow personnel to use the machine until
they have read these instructions. Save
instructions for future reference and ordering of
spare parts.
5. Make yourself familiar with all features and
control elements and with their functions prior
to operating the machine.
6. Persons below the age of 14 should not use the
machine.
7. Keep persons, especially children and pets,
away from the working area of the machine.
8. To operate this machine the manufacturer
recommends wearing the following:
- safety glasses or other suitable eye protection;
- sturdy shoes;
- no loose fitting clothing that might get caught
in the machine.
9. Protect the machine against rolling away and
use by unauthorized personnel.
10. Prior to starting the machine make sure that
there is enough fuel in the tank. Never refill fuel
in enclosed buildings when the engine is running or hot. Wipe off all spilt fuel before starting,
or wait until spilt fuel vapours have vanished.
11. Except when filling petrol, the petrol cap should
always be firmly fitted on the tank. When handling fuel, avoid naked flames, smoking and
sparks. Store fuel in appropriate containers
only.
12. Prior to carrying out cleaning, repairs or inspections make sure that all moving parts have

instructions

completely stopped. The engine ignition lever
should be set to »0« position so that the engine
cannot be started accidentally. In addition, the
gas lever must be in »Stop« position.
13. Never leave the machine unattended while the
engine is running.
14. Never run the engine in closed rooms: Danger of
intoxication!
15. Do not place hands or feet under the suction
nozzle or near rotating parts.
16. The area to be vacuumed should be clear of stones, wires etc. which could be picked up by the
rotor and flung in any direction, causing injury to
the operator or bystanders.
17. Do not vacuum materials that could clog the
rotor.
18. Always switch off the engine and wait until the
rotor has stopped completely before doing the
following:
1. Removing the foliage bag or clearing a blockage in the infeed channel, or
2. Removing the suction nozzle or clearing a
blockage in the suction nozzle
3. Repairs, adjustments or removal of foreign
items.
19. When using the foliage vacuum as a foliage blower, the protective cover at the rotor inlet has to
be properly fitted. The blower should not be pointed at persons.
20. The foliage bag should be cleaned at regular
intervals to guarantee proper filter performance.
21. Never empty the foliage bag when the engine is
running.
22. Never replace the suction nozzle or suction tube
while the engine is running.
23. Use only manufacturer’s approved accessories
and original spare parts.
24. Only qualified personnel should be allowed to
carry out repairs and maintenance.
4. Operation
As mentioned in section 2 the machine is pre-assem-
bled in the works with the exception of the foliage bag
and suction nozzle.
Fit the suction nozzle (3) and foliage bag (8) as shown
in Fig. 1, paying particular attention to the adjustment
of the Bowden cable (25/32) for the switch bar (31) to
prevent slipping of the engine clutch.
The engine is started by means of a recoil starter,
after first having set the ignition lever to »1« and the
gas lever to »start«. For further information, please
refer to the attached instructions of Honda.
The suction power of the rotor (51) is largely depen-
dent upon the height of the suction nozzle, (3) i.e. the
heavier the material to be picked up, the lower it
should be (right down for moist foliage and higher for
dry foliage).
The front and sides of the foliage bag (8) are fitted
with air-permeable filter material. The upper and rear
surface is less permeable out of consideration for the
operator. When large volumes of air are sucked in, i.e.
with a high position of the suction nozzle, additional filter surfaces can be created by opening the zips on
the right and left.
The foliage bag is full when the machine tends to tip
backwards, lifting the suction nozzle (3) at the front. In
this case the foliage bag (8) should be emptied by
opening the circumferential zip on the back and emptying it by means of the handle provided on the front
side. The opened part of the bag can be folded up out
of the way by means of a Velcro fastener.
Model LS 3500 has to be pushed over the surfaces to
be cleaned. Model LS 5000/LS 5000 H has a self-propelled drive which is started by means of the switch
bar (31) on the steering handle. Model LS 5000/LS
5000 H features free-wheeling ball bearings for curve
negotiating ability (38).
How to convert the foliage vaccum (3) into a foliage
blower: Unscrew the suction nozzle and the outlet
connecting piece (7). To cover the two openings, fit
the guard (59) supplied as an accessory. Then pull
back the locking plate (24) at the back to release the
lock and turn the rotor body (51) by approx. 90 deg.
(in counter-clockwise direction seen from the front of
the machine).
Caution:
rotation in the wrong direction might
damage cable to contact switch (5).
5. Maintenance Instructions
Strong vibrations arise when vac is on. It is therefore necessary to check screw tightness after a
few working hours.
Always set the ignition lever of the engine to »0« prior
to carrying out maintenance or repairs. To clean the
foliage bag (8), release the bag from the outlet (7)
connecting piece and undo the retaining straps. The
filter material of the foliage bag will eventually become
clogged. In this case, turn the bag inside out and
shake it out completely, or wash foliage bag in a water
bath or by rinsing with water; industrial cleaning is
also possible.
From time to time the suction nozzle (3) at the front of
the machine should be dismantled and the blower
rotor (14) inspected for damage caused by foreign
items.
Check the air pressure of the rear wheels (36/46a+b)
occasionally according to the technical data.
The drive engine should be serviced as described in
Page 4
the attached instructions of Honda.
All bearing points of the foliage vacuum have self-
lubricating ball bearings and do not have to be lubricated.
Model LS 5000/LS 5000 H: check drive after a longer
period of working time (depending on the type of
ground the vac is used on). Loosen the four screws
holding the bottom plate to uncover the complete
driving mechanism (45/66). Wear may have loosened the wheel driving chain (41/74). To adjust
distance again, loosen shaft bearings (42) and turn
bearings (42) in slot. Tighten screws carefully.
The air filter of the drive engine should be cleaned or washed out frequently because handling
foliage always involves a lot of dust.
