2 Foreword.
Dear customer and user!
Thank you for trusting our products. You ha e become owner of machine from a wide
range of machines and attachments made by ,a.s. as a system of gardening,
farming, small agricultural and communal machinery.
The mulcher Hurricane F-530 (from the year of manufacture of 2006) is a follow-up to the
pre ious generation of the machine, ery popular on the market thanks to its ery easy operation,
silent, high performing and fuel-sa ing engine HONDA. This new model of the mulcher retains all
these features and at the same time impro es the quality and performance of cutting as well as the
lifetime. The main change is a modified shape of the blade co er. It ensures better crushing of the
stand and its impro ed discharge from the blade co er space, together with new, impro ed shape of
the blade. The slide shoe was replaced by a simple leading wheel. Thanks to the leading wheel it is
easier to control the machine. The gearbox with reduced tra el speed, together with the abo e-
mentioned changes, ensure better passability through the stand and better utilization of the engine
power.

are dry and the cutting blades are capable of crushing them into small pieces which need not
be remo ed from the surface. The maximum recommended height of swards emerged in the
same period when cut is up to 40 cm. This maximum height may decrease according to sward
density, moisture content and type.
The machine control is easier thanks to the leading wheel. The height adjustment (in
two positions) is made with a spacing tube, put on the pin of the wheel hinge.
Working width must be at all times accommodated to the density of the mown
sward.

.2 Putting into operation.
The machine may be delivered without engine fillings (in dependence on different
national regulations)!
 irst thoroughly read the instruction for engine use! You can prevent a possible
damage to the engine.
1. Check oil olume in the engine and/or fill the engine with the prescribed oil grade and
olume. Fill the tank with the prescribed amount and type of petrol.
2. Mo e the accelerator le er into the front position („CHOKE“). Start the engine by
pulling on the manual starter (instructions for starting see guidelines for engine use).
3. Let the new or cold engine running on choke for about 30 seconds (accelerator le er in the
„CHOKE“ position), and then mo e the accelerator le er into the position „MAX“. In
this position let the engine running for about 30 seconds.
Do not leave the machine alone when doing this!
.3 Starting the cutting blade.
When starting the engine, the two levers on the handlebars must be in the off
position.
1. Start the engine while adhering to instructions presented in the operating manual for
engine use.
2. Set-up maximum engine re olutions by using the accelerator le er in the right part of the
handlebars crossbar. (Should the engine be cold, let it warm up at maximum re olutions
for about 1 minute).
3. Grasp the left handlebar grip with your left hand. Then slowly press the cutting blade
dri e clutch le er on the right handlebar grip with your right hand.
Press the lever slowly up to about two thirds of the stroke so that the cutting blade
can start rotating and the engine does not stall.

Starting of the cutting blade is accompanied with a partial V-belt slippage and with the
accompanying phenomena such as whistling, rattling, etc. The phenomenon usually
disappears after the belt has started properly mo ing.
4. After the cutting blade starts turning, press the le er completely to the handrail and hold it
firm.
If the blade dri e is switched on during cutting again, engine stalling may occur due to
resistance of grass biomass in the space of blade co er. This space must be – if possible – always
properly emptied when starting the blade dri e (see Chapter 6.6.4).
Note: In a new or cold engine, a few of the blade dri e starts may result in engine stalling.
The phenomenon will disappear after the engine warms up. If the blade dri e cannot be started
e en after the engine has got warm, follow the table presented in Chapter 7.6 for diagnostics.
.4 Machine travel.
Machine tra el is controlled by the le er on the left grip of the handlebars. Press the
le er completely down to the grip and the machine will start mo ing forward. Start walking
simultaneously with the le er pressing and machine start, adapting your walk pace to the
speed of the machine.
 Be prepared when the machine starts moving with a little jerk.
Note: All four main positions of the accelerator le er are arrested by means of a simple
system (dent/rib) in the le er body.

. Machine stop.
If you wish to stop the machine tra el, release the le er on the left handlebar grip. The
machine will stop mo ing but the blade will still turn. The cutting blade dri e will be
switched off after release of the le er on the right handlebar grip. The safety brake will stop
the blade.
Prior to carrying out any activities in the near vicinity of the machine, switch off the
engine and wait until the cutting blade stops! Always switch the engine off before
leaving the machine!
Never let the engine running at maximum speed or idling with the cutting blade
drive clutch released and with the released clutch of travel wheels drive for a long
time! Machine drive components (V-belt, belt pulley, clutch pulley, etc.) might
suffer damage!
If you wish to switch the engine off, do it by shifting the le er to the „STOP" position.
In the case of any critical situation, release your hold on the handlebars without any
delay. The levers will return to their zero position, the machine and the cutting
blade will stop (while the engine is still running at set-up revolutions; this is why it is
to be switched off by shifting the lever to the „STOP“ position as soon as possible!)
.6 Working with the machine.
5.6.1 Working width of the machine.
Before using the machine, the stand to be cut must be cleared of solid bodies (such

might damage the machine. If these cannot be removed, avoid working in such
places.
Working width has to be at all times accommodated to stand density!
If possible, do not use the machine on wet grass. Remember that the terrain you are
moving on must always be safe. Walk (never run) at work. Be careful especially
when changing the machine direction on slopes. Do not cut on steep slopes. When
accidentally falling, immediately release your hold on the machine.
5.6.2 Adjustment of cutting height of the machine with leading wheel
The slide shoe was replaced by a simple leading wheel on the machines of this new
generation. The machine became more controllable thanks to the leading wheel. The height adjustment
in two positions was preser ed from the pre ious generation and it is now made with a spacing tube
put on the pin of the wheel hinge (see the positions on the picture below). The wheel can be locked
against side mo ement with an auxiliary safety pin when mowing on a slope (mo ement along the
contour lines is recommended). If you use the machine on flat areas or gentle slopes, store the pin with
the safety stirrup or put it on a place on the machine protected from the cut stand.
Upper position- height of the blade above the
ground approx. cm
Lower position - height of the blade above the
ground approx. 6 cm
5.6.3 Adjustment of cutting height of the machine with slide shoe
The slide shoe may be purchased as accessory equipment under the ord. number 4205.
The cutting height is initially set in the position for higher stubble (approx. 8 cm). This
position is intended for dense, tall stands and une en terrains. If you are going to cut lower
stands (up to 15 cm) and on the areas without terrain une enness, it is possible to set the slide

shoe position for lower height of the stubble, approx. 5 cm. Always work with an assistant
when changing the slide shoe position.
1. secure the machine against self-motion (by wedging) on a solid surface or a pad
2. lift the front part of the machine, so that the inner space of the blade co er is
accessible
3. secure the machine against sudden tilt back onto the pad
4. clean the inner space of the co er on the sides, where the slide shoe is mounted (4
places)
5. dismount the slide shoe fixing (4 bolts and nuts with washers)
6. mo e the slide shoe to the other position
7. screw the slide shoe back with all the bolts and nuts
8. tilt the machine back onto the pad
5.6.4 Sward cutting.
Set the engine on the maximum speed, let the cutting blade rotate at the maximum
speed (see Chapter 6.3) and then get the machine into motion (see Chapter 6.4), facing the to-
be-cut sward.
At cutting, you should proceed only in such a way that the to-be-cut sward is on the left
side of the machine. When cutting on slopes, it is ad ised to dri e the machine along the slope
contours. Watch a maximum permissible long-term machine inclination of 20° (30° o er a
short-term)!
If the cut stand is ery dense, grown through, rotten from below or lodged, the machine
working width must be accordingly reduced, so that the cutting blade rotations are not
excessi ely slowed-down, which would result in the impaired cutting quality. Always set the
slide shoe in the position for maximum stubble height for such swards.
5.6.5 Problems at cutting.
Choking of the space under the cutting blade co er with the grass biomass shows in:
a) Engine markedly losing speed but not stalling: machine tra el to be switched off
immediately (le er on the left handrail grip), mo e the machine slightly back while the
machine front is slightly lifted by pushing down on handrails. The space under the
cutting blade co er will do itself a partial clearance from excessi e grass. Then dri e
the machine against the sward again (see Chapter 6.4).

Be very careful while lifting the machine and driving back!
b) Engine losing rotations and stalling: release both le ers on the handlebars, lift the
machine front by pushing down on handrails and mo e the machine slightly back.
Clean the space under the cutting blade space and spread the cut grass across the
ground surface. Start the engine, switch on the cutting blade dri e (see Chapter 6.3)
and dri e the machine against the sward again (see Chapter 6.4).
The engine must always be switched off when cleaning he space under the blade
cover!
Tilt the machine always only backwards onto the handlebars. Be very careful while
moving under the lifted machine! Secure the machine against its spontaneous
motion and tilt!
Be very careful while cleaning the space under the cutting blade cover. Cutting
edges of the blades are sharp. You should wear protective gloves or use a suitable
piece of branch etc.
6 Maintenance care and storage.
To ensure a long-term satisfaction with our product, it must be gi en proper care and
maintenance. Regular maintenance of the machine will pre ent its early wear pro iding at the
same time for a correct functioning of all its parts.
Prior to any machine use, check all bolts and nuts for their correct tightening. Make sure
that all safeguards are in good order. Check the blades, fixing bolts and indi idual elements
of cutting mechanism for a possible wear or damage. In order to keep a good balance of the
machine, worn-out or damaged blades and fixing bolts should be replaced with original spare
parts. All worn-out or damaged components should be replaced also for the reason of
machine safety. Oil le el in 4-stroke engines must range within limits described in the
“Instructions for engine operation and maintenance“.
Follow all instructions concerning the inter als of machine maintenance and adjustments.
It is ad ised that you keep records on the number of machine working hours and on the
conditions in which the machine was working (for ser ice purposes). The after-season
maintenance of the machine should be entrusted to one of our authorized ser ice workshops,
the current maintenance as well if you do not trust your own technical skills.
Regarding the machine weight, all maintenance and adjustment procedures are to be
done by two persons.
6.1 Machine lubrication.
6.1.1 Gear oil change and replenishment.
When replacing oils, follow the basic hygienic principles, regulations and laws on
environment protection.
The gearing works in an oil bath. Oil olume should be checked once a month (oil plugs see Fig.
5).
Minimum grade of gear oil should be GL-4, GL-5 according to API, 90 or 80W – 90 according to
SAE.
Oil replacement in a new machine is to be made after the first 5 hours of operation and then after
100 working hours or after the end of the season. This will ensure that the gears will not suffer

Hurricane F-530
with leading wheel
16
excessi e wear. The exchange inter al can be extended up to 130 hours with oils of higher grades
(API GL – 5, SAE 80W – 90). The running-up period of 5 hours must be obser ed.
Czech oils fully meeting the requirements are „MOGUL TRANS 90“ or „MOGUL TRANS
80W-90“.
Oil replacement should be made when the box is warm and oil is easy to drain.
1. Clean around the oil plugs. Underlay the machine and secure it so that a space is created under
the machine for a essel to collect oil.
2. Loosen the pour-in plug on the rear wall of the box and the drain plug in the bottom of the
gearbox (spanner No. 19).
3. After the oil has been drained, screw back the drain plug in the bottom of the box. Fill the
gearbox with the new oil (it is ad ised to use a funnel with flexible tubing). Oil le el should
reach to the lower edge of the hole. Then screw the pour-in plug back. If the seals under the
plugs are damaged, replace them with new ones.
6.1.2 Engine oil replacement.
Information is to be found in the Instructions for engine operation. To drain oil, the
machine should be either tilted to the side with the pour-in neck with oil gauge, or the
engine should be dismounted from the machine (see Chapter 7.4, items a),b),d) ).
Recommended engine oil a ailable on the Czech market and specially designed for air-
cooled engines of gardening machines is HEKRA DYNAMIC Mineral 15W-40 (API
SJ/C ).

6.2 Tightening of bolted connections.
Regularly check the tightening of the bolted connections. Always check the tightening of
bolts fastening the blade to the blade holder and blade
holder to the shaft prior to any machine use.
Tightening torque of the M10x1x25 central bolt is 38 N.m.
Tightening torque of the M10x25 side bolts is 44 N.m.
Replacing bolts, use only original spare parts
supplied by the manufacturer!

Check the bolt tightening prior to each new use as
well as during mowing, especially after a possible
impact on a solid obstacle!
6.3 Working blade replacement and sharpening.
The machine must be standing on a firm support plate and must be secured so that
the blade is easily accessible and an unexpected spontaneous machine motion
cannot occur.
Be very careful when dismounting the blade. Its cutting edges are sharp. Protect
your hands with working gloves.
The engine must be switched off and the cable end connector to the spark plug
disconnected!
Working blade replacement procedure is as follows (always work with a helper):
a) Release and unscrew outer M10x25 bolts. Then release and unscrew central
M10x1x25 bolt and remo e the blade and the blade holder from the blade shaft.
b) Plane the blade and sharpen the cutting edges. Inclination of the sharpened cutting
edge should be 25° with respect to the lower plane of the blade. The blade must be
well balanced after the sharpening; the material loss at sharpening the two cutting
edges should be therefore identical.
c) Mount the blade and the blade holder back onto the blade shaft in a re erse order of
operations.

Central M10x1x25 bolt has a fine thread and therefore it must not be confused with
outer bolts whose threads are normal!
d) Tighten the bolts at a prescribed tightening moment (see Chapter 7.2).
Should there be excessive vibrations on the machine handlebars after the
installation, the blade must be unconditionally balanced once again!
Note: Manufacturer does not answer for any damages caused by the machine due to unskilled repair or treatment
of blades without the use of the original spare parts.
6.4 V-belt replacement and adjustment of tightening pulley.
V-belt should be replaced according to its wear (cracked sides, torn belt, sides worn out down
to belt carrier fibres, belt “pulled“ out of shape) or after about 200 hours of operation at the
maximum. In this machine, the belt pulled out to maximum is considered a belt in which
distance between inner belt surfaces (at the pressed le er of mowing disk dri e clutch) is less
than 7 mm. The replacement procedure is as follows:
a) Drain petrol from the engine tank. Remo e the red
ball from the accelerator le er. Dismount the
accelerator le er (2x spanner No. 8) from the
handlebars. Bowden cable should in no case be
dismounted from the control mechanism on the
engine!
b) Unscrew three safety nuts (spanner No. 13) on the
engine flange and pull the engine out from the
machine frame upwards. Ne er use force to pull
the engine out from the frame!
Never put the engine on the side. Oil might get into the exhaust or into the air
cleaner. Best engine placing is with the lower flange dwelling on two scantlings
which are at least 7 cm high.
c) Dismount the V-belt co er (spanner No. 10). Dismount the front guide of the V-belt
and the bolt on the pulley arm (spanner No. 10). It is sufficient to unscrew the bolt for
about 15 mm, and then it is possible to take the V-belt out of the tightening pulley.

d) Take the old V-belt off and replace it with a new one. Original V-belt marking is
OPTIBELT X13x1335 Ld 6T6K, ord. No. 184 608. It is also possible to use an
equi alent V-belt made by other manufacturers at a size of A13x1300 Li (Li=internal
length) or A53“ (53“ is the external length La). Howe er, the belt must be made
without rubber on sides! Only such a belt model will guarantee that the V-belt is not
extended and the blade dri e start is smooth at engaging the clutch.
Should another than the original recommended type and size of the belt be used, the
machine manufacturer does not answer for correct and full functioning of the drive!
e) After you put the new V-belt on the pulley, insert the V-belt into the groo e in the
tightening pulley and fully tighten the bolt on the pulley arm.
f) Put the engine back in place. Pins in the dri ing belt pulley must fall into holes in the
rubber element on the dri en part of the clutch, installed on the gearbox. Bolt the
engine with three M8 nuts with flat washers. Screw the accelerator le er back onto the
handlebars and put the red ball back on the accelerator le er.
g) Put the V-belt into the groo e in the belt pulley on the engine.
h) Check the operation of the tightening pulley and adjustment of guide lamination. With
the le er on the right handlebar grip fully pressed down, the pulley must ensure
sufficient belt tension (spring on the cable being extended by about 10 mm as
compared with loose condition). Possible corrections are to be made by means of
adjustment bolt No. 1 (see Fig. 10). With the le er switched off, the pulley must be
tilted away from the longitudinal machine axis at an angle of max. 0 - 5° = with the
belt con ex side being approx. 1,5 – 2,0 cm from the bottom of the tightening pulley
(see Fig. 9). The wire in the Bowden cable of the tightening pulley must exhibit no
slackness. In the case that the adjustment bolt is completely screwed out and it is
necessary to tighten the V-belt, the spring on the cable can be hooked into the front
hole on the arm of the tightening pulley (see Fig. 9 bottom, note: this connection can
be used already from the manufacturer) and belt tension can be adjusted once again.
Guide lamination on the right side of the machine must be parallel to the belt and at a
maximum distance of 1 – 2 mm from the belt con ex side.
i) Mount the front belt guide back to its original position and mount back the plastic belt
co er.
If the gearbox disassembly from the machine frame occurs, the reverse assembly
must be made with a proper axial alignment of the gearbox and engine shafts. This
is why the operation should be made by an authorized service workshop which has
to have available an original and by manufacturer approved centring fixture.

6. Adjusting the wires of pulley, brake and wheel drive clutch.
In order to guarantee low operating forces on le ers which control the dri e switching, it
is ad isable to lubricate the wires in Bowden cables at least 2x during the season with some
of oils a ailable in atomiser (e.g. SILKAL, MD Spray, WD40). Correct functioning of the
machine also requires correct adjustment of dri e controls.
The wire in the Bowden cable must always exhibit a slight slackness of approx. 1 mm
(with the le er of the cutting disk dri e clutch and brake released) so that the brake
performance is sufficient. In order to achie e clearance of the brake wire in the Bowden
cable, adjustment bolts ha e to be screwed into the chassis or handlebars crossbeam at the
adjustment.
The wires in the Bowden cable of pulley and in the Bowden cable of wheel dri e clutch
must be without slackness, slightly tense. In order to make the wires tense, adjustment bolts
ha e to be screwed out of the chassis or handlebars crossbeam at the adjustment.
Safety nuts in all adjustment bolts should be tightened by using two flat wrenches No.
10 or 9 (in accordance with the size of the M6 nut used). If there is no more step to be used in
the adjustment bolt, it is possible to displace the hook on the wire into another hole in the
sheet-metal le er on the handlebars (or on the wheel dri e clutch le er on the gearbox and on
the arm of the tightening pulley – see Figs. 9 and 10) so that the initial tension of the wires
can be again regulated by the adjustment bolt.
