Maintenance Of The Blade Shaft; Changing The Ribbed V-Belt; Servicing The Wheels; Servicing The Engine - Sabo 38-BV Betriebsanleitung

– For loaded goods that can roll, we recommend using direct strapping with four
lashing straps. Secure the wheels of the equipment in such a way that it does not
move during transportation.
NOTE
Do not tighten the belts too firmly. Fixing the equipment too firmly can cause
damage

Maintenance of the blade shaft

Before using the machine, always check the condition and firm seating of the blades.
Worn or damaged blades should be replaced immediately.
WARNING
Always have replacement of the blade shaft carried out by an authorised
workshop. An incorrectly assembled blade shaft can cause parts to become
detached, possibly leading to serious injury.
Only use genuine scarifying cutter blades for replacement. Non-equivalent spare parts
can damage the machine and are a safety hazard.
Replacement scarifying cutter blades must be marked permanently with the name
and/or company logo of the manufacturer or supplier and the part number.

Changing the ribbed V-belt

For replacement, use only original drive belts.
Let the ribbed V-belt to be replaced only in authorized professional workshop.

Servicing the wheels

Lubricate the wheel bearings once a year or every 15-20 operating hours.
– To do this, remove the wheel caps, screw the wheel axles out and take the wheels
off.
– After the bearings have been lubricated with roller bearing grease "KAJO-
Langzeitfett LZR 2", push the wheels back in place and tighten the wheel axles to
such an extent that the wheels can just about turn easily but without play.

18 SERVICING THE ENGINE

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
To clean the scarifier and for maintenance work tip it forwards. When tipping the
scarifier forwards, make sure that the ejection flap is not damaged. Secure the
scarifier in the raised position!
ATTENTION
When tilting the machine upwards, 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 (Illustration Y1 + Y2 + Y )

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. 5 operating hours. Later, it
should be done every 50 operating hours or at least once per season.
Check the oil level regularly. Check the oil level every 8 hours or prior to starting the
engine.
– 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 (1) Y .
– Close the fuel tap (2) Y2 .
– Renew the oil as long as the engine is warm.
– To change the oil, undo the oil drain screw (4) Y1 .
– Tilt the scarifier 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 scarifier straight and insert the oil drain screw (4) again and tighten
Y1 .
– Fill with fresh motor oil (see the chapter Check the oil level and fill with oil,
Figure Y1 ).

Cleaning and replacing the air filter (Illustration W )

IMPORTANT
Never let the engine start or run whilst the air filter is removed.
– Loosen the nut (1) on the air filter cover (2) and remove the cover.
– Remove the fastening nut (3) and remove the filter (4). Remove the pre-filter (5)
from the paper filter element.
– Clean the paper filter element every 25 operating hours.
If slightly dirty, knock the dirt off; if very dirty or damaged, replace it. Do not blast
out the paper filter using compressed air. Do not grease it.
– Clean the pre-filter every 25 operational hours.
Wash the pre-filter in hot water with liquid detergent, rinse it out, press out excess
water and allow it to dry thoroughly in air. Do not lubricate the pre-filter with oil.
– Insert the dry pre-filter on the paper filter element and fit both on the stud bolt (6)
and air filter plate (7). Pay attention to ensure that the filter engages safely with the
filter plate. Fasten the filter with the nut (3).
– Put the cover (2) on the air filter and fasten it with the nut (1) on the air filter plate
(7).
In the case of unfavorable operation conditions (severe formation of dust), cleaning is
required after every scarifying procedure. Replace the paper filter element and pre-filter
annually.
Safety instruction! (Please see original spare parts and accessories for Order No. of filter element and pre-
See table for explanation filter)

Checking the spark plug (Illustration Y )

To check for wear, remove the spark plug connector (1) and unscrew the spark plug (2).
If the electrode is badly worn the spark plug must be replaced as a matter of course.
(Order no. see original spare parts list and accessories).
Otherwise it is sufficient to clean the spark plug and set the electrode gap to 0.76 mm.
Screw the spark plug (pay attention to sealing ring) into the engine by hand and tighten
using the socket wrench. Press on spark plug connector. Replace the spark plug
annually.
Correct winter storage of the engine (or when not used for a long period
of time)
– 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 (1) Y .
– Close the fuel tap (2) Y2 .
– Drain the oil and fill with fresh motor oil as long as the engine is still warm (see the
chapter Oil change ).
– Remove grass and mowing deposits from the cylinder and cylinder ribs, under the
engine hood and around the silencer.
– Always keep the equipment in a clean state in a closed, dry room and inaccessible
to children.
