We recommend that you handle the removed vegetation such that the uncut vegetation remains to the left of the
machine. The vegetation is processed more efficiently. The opposite procedure is also fine.
Thick and high vegetation raises the machine; do not try to keep the front spur always on the ground. You may instead
aid the machine by lifting and cutting only the upper part of the vegetation while turning the wheel drive off. Afterwards
return to this area and cut it with the spur on the ground.
2.4.3.4 Problems during cutting
Be especially careful when tilting the machine up or when moving backward with the machine!
The machine must only be tilted to the rear on the handlebars. Always exercise increased caution when you are
moving in the area of a raised machine! Ensure that it cannot be set in motion when unattended!
The engine must always be turned off when cleaning the deck operating space!
Use increased caution when cleaning the area below the upper cover. The blades are sharp. Use work gloves to
protect your hands during cleaning or use an appropriate object, e.g. piece of branch.
Always wait for the work tool to stop before performing any activity on the machine or its vicinity.
1) The engine loses rpm, but does not stall.
Immediately turn off the machine wheel drive and gently lift the front of the machine (by pressing downwards on the
handlebars) while slightly moving backwards. The operating space shall clean itself of excessive debris. Afterwards,
drive over the vegetation once more.
2) The work tool has stopped, the motor has stalled.
Release both control levers on the handlebars and lift the front end of the machine. Move the machine slightly
backwards. Clean out the space below the upper cover and scatter the grass debris around the immediate area. Start
the engine, engage the work tool drive and drive again against the brush.
3) The removed vegetation sticks to the side of the deck cover (probably due to thick and grown in vegetation).
Try to change the direction of cutting or lift the front end to remove the top part of the vegetation. Drive afterwards
again towards the vegetation.
2.5 Maintenance, care, and storage
Due to the mass of the machine, maintenance and adjustment should be performed with the assistance of
another person.
Long-term satisfaction requires due diligent care when cleaning and maintaining the product. Regular maintenance will reduce wear and
ensure proper function of all of its parts.
Follow all directions relating to maintenance intervals and machine adjustments. We recommend that you administer a record of the
number of machine operating hours and the conditions in which it operated (for servicing needs). We recommend that you bring your
machine to one of our authorized service centres for after-season maintenance and for common maintenance if you feel uncertain about
your technical abilities.
A good aid for monitoring the number of engine hours is the
VARI PowerMeter
. Ask your retailer for information!
Before every use, check that the screws that fasten the work tool and the protection elements, covers, and
engine are properly tightened!
Replace lost screw connections with original parts that were specifically designed for the given location. The use
of low-quality aftermarket parts may lead to injury or may damage the machine!
2.5.1 Drive wheels
2.5.1.1 Tyre pressure
To assure proper function and to provide long life of drive wheels, especially tyre-casings, the pressure in the tyres must be checked.
Perform the inspection before using the machine. If the machine will not be used for an extended period of time, fill the tyres to the
MAX
(see below) tyre pressure. The tyre pressure should be the same in both tyres – the machine is better able to maintain a straight path.
Do not exceed the maximum tyre pressure – the tyre may explode!
If the tyre pressure is low, the tube valve may be cut.
MAX
imal (recommended) tyre pressure:
23 PSI
(
160 kPa
or
1.6 bar
or
1.57 atm
or
0.16 Mpa
)
