Switching Off The Engine (Illustration F + Y2 ); Emergency Stopping; Adjusting The Scarifying Depth; Setting (Illustration T2 + V2 + Z2 ) - Sabo 38-BV Betriebsanleitung

11 SWITCHING OFF THE ENGINE (ILLUSTRATION F + Y2 )

– Release the safety control bar (1) F . The engine switches off and the cutting tool
comes to standstill. Attention! The cutting tool runs for a while!
– Close the fuel cock (2) Y2 .

12 EMERGENCY STOPPING

Release the safety grip.
– The cutters will stop. Attention! The cutting tool runs for a while!
– The engine will stop.
NOTE
Before every scarifying job, make sure that the safety control bar is working
perfectly.
– When the control bar is released, the engine must switch off and the cutting
tool must come to a standstill (Note! The cutting tool runs on for a while!).
If this is not the case, please consult your nearest authorised workshop.

13 ADJUSTING THE SCARIFYING DEPTH

The scarifying depth must only be adjusted with the motor switched off!
To work with the scarifier, the scarifier lever is pushed forward into the "scarify" position
T2 . This lowers the cutter shaft and the blades penetrate the turf.
The working depth depends on the blade wear, and must also be set taking into
account the relevant grass and ground conditions.
Always check and adjust the scarifying depth on a level area of lawn.
With the blade shaft lowered, the blades should just be in contact with the turf. A
working depth of up to 3-5 mm is recommended. In the case of a well-tended lawn with
soft ground, the working depth can be set slightly deeper. In case of a very mossy lawn
surface, the initial working depth should be slightly less.

Setting (Illustration T2 + V2 + Z2 )

On a new machine, the cutter shaft is in the uppermost position. The scarifying depth is
adjusted as follows:
– Tip the scarifier lever forwards in order to lower the cutter shaft T2 .
– Turn the rotary knob (1) to the left until the cutter shaft is just scratching the
surface of the lawn V2 .
– Align the pointer (2) with the arrow on the housing (zero adjustment) V2 .
– Now turn the rotary knob to the left so that the cutter shaft cuts into the ground.
The pointer is automatically turned as well V2 .
– A complete revolution (360°) to the left will lower the cutter shaft by 1.5 mm.
– The scarifying depth should initially be approx. 3–5 mm, in other words, 2–3
revolutions of the rotary knob to the left.
– The lever is set vertically to raise the cutter shaft from the set working position. The
adjusted scarifying depth is not altered by this V2 !
After a few operating hours, the cutter shaft may need to be re-adjusted because of
wear. The more intensive the use, the greater the wear to the blades. Hard or very dry
ground will increase the wear to the blades.
Then carry out the working depth adjustment as described above.

14 GRASS COLLECTOR

Operation with grass collector (accessory)

The scarifier can also be operated with a grass collector (Order no. – see Original
replacement parts and accessories).
WARNING
When operating the equipment with a collecting bag, the bag must be completely
assembled and in technically perfect condition.
Safety instruction!

See table for explanation of symbols page 3

Attaching the grass collector to the scarifier (Illustration L2 + S1 )

– Open the ejection flap of the scarifier upwards.
CAUTION
The exhaust gets very hot. If touched it can cause serious burns.
Always hold the ejection flap on the right when opening L2 !
– Pick up the collecting sack by the carrying strap and hang it in the scarifier casing
with its two side hooks upwards S1 .
– Attach ejection flap to collector.
When using the machine, ensure that the collector is emptied in good time. The grass
collector will only collect grass properly if air can pass through it freely. If the cutter is
set too low the grass collection is impaired.
IMPORTANT
Do not clean the grass collector with hot water!

Emptying the grass collector

– Switch of the motor and wait until the cutters come to a stop.
– Lift the ejection flap.
CAUTION
The exhaust gets very hot. If touched it can cause serious burns.
Always hold the ejection flap on the right when opening L2 !
– Remove the full grass bag from the scarifier by the carrying strap – the ejection
flap closes automatically.
– Shake out of the grass bag thoroughly, holding it by the carrying strap and the
moulded handle on the bottom.

Operation without grass collector

WARNING
When scarifying without grass collector the ejection flap on the scarifier housing
must always be closed (flap down).

15 SCARIFIER OPERATION

NOTE
To protect the cutter, avoid tight curves and raise the cutter before turning.

Using the machine on slopes

NOTE
The device can be used on banks and slopes with a gradient of up to 46% (25°
angle). Any steeper slopes can lead to engine damage.
For safety reasons, however, we urgently recommend you do not exploit this
theoretical performance potential. Always make sure you have a firm stance.
Manually guided scarifiers should never be used for slopes with a gradient in
excess of 26% (15° angle of slope). Stability may be lost!

Checking the oil level

Check the oil level before scarifying (see the chapter Check the oil level and fill with
oil). Never let the engine to run with too little or too much oil. Irreparable damages
could occur.

Checking operating safety

The scarifier is equipped with a motor stop device.
Before every scarifying job, make sure that the motor stop safety control bar is working
perfectly. When the control bar is released, the engine and the cutting tool must come
to a standstill (Note! The cutting tool runs on for a while!). If this is not the case, please
consult your nearest authorised workshop.
After release, the bar must always return to the position shown in the "component
description" diagram.
If this is not the case, it must be checked immediately by an authorised workshop.
Machine safety and protective devices must not be manipulated or disabled.
Make sure that all protective devices have been attached properly and are not
damaged.
To avoid danger, check the condition and tight fit of the cutter blades before every
scarifying job (refer to the chapter "Cutter blade shaft care" for more details). Always
have work on the cutter blade shaft done by a specialist workshop. If the cutter blade
shaft is assembled incorrectly parts can become loose, which can lead to serious
injuries.
