Sabo 54-pro k vario plus, Operator'S Manual

10

–  Transport the unit upright on all 4 wheels to avoid fuel loss, damage to the

equipment and personal injury.

–  Remove the collecting bag and secure it separately during transport
–  Secure the equipment with approved load-securing devices (e.g. tie-down straps

with clamping elements) on or inside the vehicle. Tie-down straps are belt bands

made of synthetic fibres. Every tie-down strap is marked with a label. The label
contains important details for application. The information on this label must be
heeded when using the tie-down strap.

–  For loaded goods that can roll, we recommend using direct strapping with four

lashing straps. For this purpose, the belts are fastened directly on the fastening

points on the equipment (see Figure

N4

) and in the tie-down strapping points on

the loading surface and slightly pre-tensioned.

NOTE

Do not tighten the belts too firmly. Fixing the equipment too firmly can cause
damage.

CAUTION

When moving the bar for transport and storage purposes, the bar may fold over

unintentionally during loosening of the hexagon nuts (5)  C1  (only loosen them
to such an extent that the bar can move freely) and the attachment screws (1)

 C1  between the base of the bar and the bar connection point. In addition,
beware of potential squashing spots between the base of the bar and the bar

connection point/housing. This may result in risk of injury!

Maintenance of the blade

A sharp blade guarantees optimum cutting performance. Before you start mowing,

always check the condition and firm attachment of the cutting blade. The blade

attachment screw must always be tightened by an authorised workshop. If the blade
screw is too tight or too loose, the blade coupling and cutter bar can become damaged

or loose which can lead to serious injuries. A worn or damaged blade must always be
replaced.

Sharpening and balancing the blade (Illustration  Q )

WARNING

The sharpening and balancing of the blade should be carried out only by an

authorized specialist workshop. An improperly sharpened or unbalanced blade
can cause severe vibrations, and damage the lawnmower.

The cutting edges of the blade must only be ground down to the mark (1) (see

illustration

Q

 ) on the blade (ring). Warning! Keep to a grinding angle of 30°.

Your professional workshop can check this value - (grinding limit) for you!

WARNING

A blade by which the wear limit (marking) has been exceeded can break off and

spin away; this can cause severe injuries.

Replacing the blade

WARNING

The cutting blade bar must always be replaced by an authorised workshop. A

wrongly assembled cutting blade coupling or a blade screw that is tightened too
tightly or too loosely can allow the cutting blade bar to become loose and cause

severe injuries.

–  Only use genuine cutter bars for replacement. Non-equivalent spare parts can

damage the machine and are a safety hazard.

–  Replacement cutting tool must be marked permanently with the name and/or

company logo of the manufacturer or supplier and the part number.

Servicing the front wheels

The wheels are equipped with maintenance-free bearings. Maintenance is not required.

Servicing the rear wheel drive (Illustration  R )

Lubricate the wheel bearings every 50 operating hours.
–  Pull the drive wheels off after loosening the nuts and removing the dust cap from

the wheel axle.

–  Remove the wheel cover, pay attention to the thrust washer.
–  Remove any soiling from the wheel cover, the free-wheeling pinion on the gear

shaft and the gear rim on the inside of the wheel.

NOTE

Do not remove the free wheel pinion from the gear shaft!

–  Lubricate the wheel axle using the roller bearing grease "KAJO-Longlife grease

LZR 2". Do not lubricate the free-wheeling pinion and gear rim in the wheel!

–  Set the wheel cover in place and push the start-up disc onto the wheel axle. When

putting the drive wheel in place make sure the pinion and gear rim interlock, turn
the wheel on the axle slightly to achieve this if necessary.

–  Set the dust cap in place, fix using the hexagon nut and tighten to such an extent

that the wheels can just about turn easily but without play.

Servicing the drive

–  It is absolutely essential that the Bowden cable runs easily for switching on and off,

so that the control drive works perfectly.

Changing the drive V-belt

The drive V-belt must be replaced by a specialist workshop.

Changing the brake clutch

The brake clutch must be replaced by a specialist workshop.

Adjustment of the blade brake Bowden cable

The blade-brake throttle cable must be adjusted at least once per mowing season by an

authorised workshop.
Correct adjustment of the throttle cable guarantees the most important safety functions

of the control bar. As soon as the control bar is released, the cutter bar must come to a
standstill within three seconds.

20 SERVICING THE ENGINE

Safety instruction!

See table for explanation of symbols

page 2

WARNING

Avoid injury!  Engine exhaust fumes contain carbon monoxide and can cause
serious illness or death.

Do not run an engine in an enclosed area, such as a garage, even with doors and
windows open.

Move the machine to an outside area before starting the engine.

IMPORTANT
For cleaning and maintenance work, always close the petrol tap and ventilation

valve (1)  A , tilt the mower forwards  O  (spark plug facing upwards). If it should
become necessary to place the mower on its side, then place it on the exhaust

side, never on the carburetors side, as otherwise start-up problems could occur.
When tilting the mower forwards make sure the ejection flap does not get

damaged. Secure the mower in its raised position!

ATTENTION

When tilting or placing the mower on its side, ensure that no oil or fuel comes out
of the machine. Fire hazard!

The regular implementation of the prescribed maintenance and care work are the

prerequisite for a permanent and fault-free functionality of the motor and also the basic
requirement for any guarantee claims.

The motor should be kept clean, particularly on the outside, and the silencer and
cylinder area must always be kept free from foreign bodies (e.g. grass residue). The

exhaust and motor reach very high temperatures when in use. Flammable foreign
bodies such as foliage, grass etc. may catch fire.

Perfect cooling can also only ensured when cylinder ribs are always clean.

IMPORTANT

Never use a pressure cleaner or ordinary water jet to clean the motor. Damages
or expensive repairs can be the consequence of such action.

Oil change

NOTE

For environmental reasons, we recommend that the oil change is performed by
an authorised workshop.

The first oil change in a new engine is required after approx. 20 operating hours. Later,

it should be done every 50 operating hours or at least once per mowing season.
–  Before the engine or the equipment is tilted to drain oil, empty the petrol tank and

let the engine to run until it stops due to lack of fuel.

–  Stop the engine and remove the spark plug connector.
–  Renew the oil so long as the engine is warm.
–  To replace the oil, remove the dipstick from the oil filler neck and set the mower on

its side so that the used oil can drain into a container.

Do not drain used oil into the sewage system or soil; dispose of it according
to the local regulations.

–  Position the mower straight and fill brand-name oil into the spout (for quantity and

quality, see technical data). Insert the dipstick but do not screw it tight, check the
