Solo 550 Manuel D'utilisation page 22

To install the grass catcher, lift up the discharge chute
deflector (item 7) with one hand - with the other hand,
hold the grass catcher bag (item 6) on the frame bar and
hook at an angle from above into the chassis fitting.
Please note: The discharge chute deflector
(item 7) is designed for your personal safety.
The deflector must be permanently closed when using the
lawnmower without grass catcher (item 6).
Adjusting the cutting height
Your lawnmower is equipped with a variable wheel
adjuster ranging from 30 – 80 mm. The wheel adjuster
acts on all wheels via a central adjusting mechanism (item
13). Rotating the adjuster clockwise reduces the cutting
height, turning anti-clockwise increases the cutting
height. The cutting height can be checked on the scale
adjacent to the central wheel adjuster (Fig. 16).
Engine
Before starting the engine for the first time,
thoroughly read the engine operating
instructions supplied and the following
instructions. Only by observing these operating
instructions can the long service life of the engine and
your warranty be assured.
Self-drive with variable speed selection
(type 550-RS/550-HR)
Your SOLO lawnmower 550-RS/550-HR is equipped with a
variable speed self-drive mechanism. The drive is provided
by belt via a gearbox with variable speed driving the rear
wheels.
The variable driving speed can be selected as required
using the control lever (item 4).
Position 1 = approx. 2.6 km/h
Position 3 = approx. 4.8 km/h
Note: Only change the driving speed via the
control lever (item 4) with the engine running.
In use, the driving speed can be changed at random with
the drive engaged (item 4).
Starting
For mowers with self-drive, disengage the self-drive
before starting.
For starting, position yourself to the side or
behind the mower. Always maintain the
safety distance provided by the handle
length (Fig. 8). The engine is controlled via the
throttle control (item 3). Caution: The cutting blade rotates
as soon as the engine starts. Never position hands or feet
under the cutting deck.
Note: To disengage the engine brake during
starting, press the brake bar A against the
handle (Fig. 7).
Cold start Move the throttle control to the choke symbol.
Note: For models 550 and 550R, the choke position
is automatically adjusted through a bimetal sensor
subject to engine temperature (Ready-Start®). These
models require no manual adjustment for a cold start.
Starting a warm engine
Move the throttle control to max (Fig. 6).
- pull out the starter cord until resistance is felt
- then pull through in one firm movement (Fig. 8).
Note: If the brake bar is not pressed against the handle
during starting, the electronic ignition will be short
circuited, and the engine brake will continue to be
engaged. In this situation (Fig. 3), the engine cannot be
started either with the manual or the electric starter.
Electric starter (550 RS)
Insert the ignition key into the ignition (item 16) on the
throttle control, and turn the key 1/4 turn clockwise.
After the engine has started, move the throttle control
(item 3) to the required position (max- eco- min) (Fig. 6).
Self-drive
On lawnmowers with self-drive, control lever (B) is
positioned in front of the handle. Only engage the drive
mechanism with the engine running. To engage the
self-drive mechanism, pull the control bar (B) towards
the handle. Release the control bar to disengage the self-
drive. With the control bar released, there is no drive and
the lawnmower can be pushed forwards or backwards as
required (Fig. 7).
