d d on th st ring handl to adjust th suction
h ight of th nozzl (3).
Th machin can b conv rt d into a foliag blow r
(s 4. Op ration for furth r d tails).

compl t ly stopp d. Th ngin ignition l v r
should b s t to »0« position so that th ngin
cannot b start d accid ntally. In addition, th
gas l v r must b in »Stop« position.
13. N v r l av th machin unatt nd d whil th
ngin is running.
14. N v r run th ngin in clos d rooms: Dang r of
intoxication!
15. Do not plac hands or f t und r th suction
nozzl or n ar rotating parts.
16. Th ar a to b vacuum d should b cl ar of sto-
n s, wir s tc. which could b pick d up by th
rotor and flung in any dir ction, causing injury to
th op rator or bystand rs.
17. Do not vacuum mat rials that could clog th
rotor.
18. Always switch off th ngin and wait until th
rotor has stopp d compl t ly b for doing th
following:
1. R moving th foliag bag or cl aring a block-
ag in th inf d chann l, or
2. R moving th suction nozzl or cl aring a
blockag in th suction nozzl
3. R pairs, adjustm nts or r moval of for ign
it ms.
19. Wh n using th foliag vacuum as a foliag blo-
w r, th prot ctiv cov r at th rotor inl t has to
b prop rly fitt d. Th blow r should not b poin-
t d at p rsons.
20. Th foliag bag should b cl an d at r gular
int rvals to guarant prop r filt r p rformanc .
21. N v r mpty th foliag bag wh n th ngin is
running.
22. N v r r plac th suction nozzl or suction tub
whil th ngin is running.
23. Us only manufactur r’s approv d acc ssori s
and original spar parts.
24. Only qualifi d p rsonn l should b allow d to
carry out r pairs and maint nanc .
4. Operation
As m ntion d in s ction 2 th machin is pr -ass m-
bl d in th works with th xc ption of th foliag bag
and suction nozzl .
Fit th suction nozzl (3) and foliag bag (8) as shown
in Fig. 1, paying particular att ntion to th adjustm nt
of th Bowd n cabl (25/32) for th switch bar (31) to
pr v nt slipping of th ngin clutch.
Th ngin is start d by m ans of a r coil start r,
aft r first having s t th ignition l v r to »1« and th
gas l v r to »start«. For furth r information, pl as
r f r to th attach d instructions of Honda.
Th suction pow r of th rotor (51) is larg ly d p n-
d nt upon th h ight of th suction nozzl , (3) i. . th
h avi r th mat rial to b pick d up, th low r it
should b (right down for moist foliag and high r for
dry foliag ).
Th front and sid s of th foliag bag (8) ar fitt d
with air-p rm abl filt r mat rial. Th upp r and r ar
surfac is l ss p rm abl out of consid ration for th
op rator. Wh n larg volum s of air ar suck d in, i. .
with a high position of th suction nozzl , additional fil-
t r surfac s can b cr at d by op ning th zips on
th right and l ft.
Th foliag bag is full wh n th machin t nds to tip
backwards, lifting th suction nozzl (3) at th front. In
this cas th foliag bag (8) should b mpti d by
op ning th circumf r ntial zip on th back and mp-
tying it by m ans of th handl provid d on th front
sid . Th op n d part of th bag can b fold d up out
of th way by m ans of a V lcro fast n r.
Mod l LS 3500 has to b push d ov r th surfac s to
b cl an d. Mod l LS 5000/LS 5000 H has a s lf-pro-
p ll d driv which is start d by m ans of th switch
bar (31) on th st ring handl . Mod l LS 5000/LS
5000 H f atur s fr -wh ling ball b arings for curv
n gotiating ability (38).
How to conv rt th foliag vaccum (3) into a foliag
blow r: Unscr w th suction nozzl and th outl t
conn cting pi c (7). To cov r th two op nings, fit
th guard (59) suppli d as an acc ssory. Th n pull
back th locking plat (24) at th back to r l as th
lock and turn th rotor body (51) by approx. 90 d g.
(in count r-clockwis dir ction s n from th front of
th machin ).
Caution: rotation in the wrong direction ight
da age cable to contact switch (5).
5. Maintenance Instructions
Strong vibrations arise when vac is on. It is there-
fore necessary to check screw tightness after a
few working hours.
Always s t th ignition l v r of th ngin to »0« prior
to carrying out maint nanc or r pairs. To cl an th
foliag bag (8), r l as th bag from th outl t (7)
conn cting pi c and undo th r taining straps. Th
filt r mat rial of th foliag bag will v ntually b com
clogg d. In this cas , turn th bag insid out and
shak it out compl t ly, or wash foliag bag in a wat r
bath or by rinsing with wat r; industrial cl aning is
also possibl .
From tim to tim th suction nozzl (3) at th front of
th machin should b dismantl d and th blow r
rotor (14) insp ct d for damag caus d by for ign
it ms.
Ch ck th air pr ssur of th r ar wh ls (36/46a+b)
occasionally according to th t chnical data.
Th driv ngin should b s rvic d as d scrib d in

th attach d instructions of Honda.
All b aring points of th foliag vacuum hav s lf-
lubricating ball b arings and do not hav to b lubri-
cat d.
Mod l LS 5000/LS 5000 H: ch ck driv aft r a long r
p riod of working tim (d p nding on th typ of
ground th vac is us d on). Loos n th four scr ws
holding th bottom plat to uncov r th compl t
driving m chanism (45/66). W ar may hav loos -
n d th wh l driving chain (41/74). To adjust
distanc again, loos n shaft b arings (42) and turn
b arings (42) in slot. Tight n scr ws car fully.
The air filter of the drive engine should be clea-
ned or washed out frequently because handling
foliage always involves a lot of dust.
6. Spare parts
A spar parts drawing and spar parts list is atta-
ch d. Pl as id ntify th r quir d spar parts
according to th drawing and stat th articl num-
b rs giv n in th spar parts list on all ord rs.
