1.6 Lighting devices on single-axle tractors
Here one must differentiate whether the one axled tractor
•is guided by a pedestrian on the shafts,
•is driven from a seat cart (single-track trailer) or
•driven from a trailer.
One axled tractors, which are guided by a pedestrian on the shafts, require during darkness - or
when the weather requires – at least one simple lamp with white light, which should be attached
to the left side or carried along manually, so that the light is well visible to oncoming and pass-
ing traffic (§ 50 Para. 2 of the Road traffic act and § 17 Para. 5 of the Road traffic act).
One axled tractors which are driven from a seat cart or a trailer
•must be equipped up to a width of 1000 mm with one headlight,
•beyond a width of 1000 mm with two headlights
, which when pulling a one axled trailer can be fastened to this (§ 50 Para. 2 of the Road traffic
act).
If the one axled tractor is driven from a single-track seat cart, then a triangular reflector and a
taillight must be attached (§ 53 Para. 6 of the Road traffic act), blinking lights (travel direction
indicator) are not required for a seat cart. (§ 54 Para. 5 No. 5 of the Road traffic act).
For one axled tensile or work machines, which are operated by a walk-behind person, no operat-
ing permit or driver's license is required.
During transport of a one axled tractor with trailer on public streets, which is used for lof pur-
poses, the operating permit is sufficient up to a design-related maximum speed of 20 km/h. It

1.10 Safety measures at the work site
•When starting the engine, the traction drive and gear box must be decoupled.
•Travel, steering, braking as tilt behavior are influenced by tool attachments. There-
fore ensure sufficient steering and braking capability and adapt the work speed to the
environmental conditions!
•When driving on hills, in valleys or across slopes, avoid sudden curves.
•Driving downhill in neutral gear is prohibited! The machine can roll away due to its
own weight!
•When the engine is running, wearers of pace makers may not touch the current-
carrying parts of the ignition system.
•Before starting to drive, check brakes and brake effectiveness.
•Remove larger objects from the work area (e. g. boards, cables, rocks, etc.).
•Keep hands and feet away from moving parts during operation.
•Ensure sufficient lighting in the work area.
•Work cross-wise along the slope, never up or down it!
•Be particularly careful when changing the travel direction on the slope.
•Never decouple and switch gears on inclines.
•Never leave the operator position during the work.
•Never make changes or repairs to load-carrying and safety-related parts (frames, ax-
les, etc.)
•In case of damages, stop the machine immediately. Pull out spark plug connectors on
the main engine and have damages repaired!
•Should the machine be used for cutting fruits, which are considered food, such places
which come into contact with the food may not be lubricated with machine oil or
grease or protected against rust.

1.11 Protective devices
The -2-wheel tractor is equipped with a safety stop lever on the steering shaft (left)
which shuts off the ignition system when released i.e. the engine is stopped - Stop setting, see
figure 3.
Warning!
The engine overtravels due to centrifugal mass!
•During operation of the -2-wheel tractor the safety stop lever must be pressed
down - operating position.
•The safety stop lever must be pressed when the machine is started, the clutch pulled and
blocked with the interlock - starting up, see figure 2.
•It is prohibited by the company to leave the safety stop lever in the starting position
(safety stop lever pressed + clutch pulled + interlock latched) if the machine should be
cleaned, have maintenance performed on it or be abandoned - e.g. cleaning the snow blow-
er - the device must be brought to a stop with the safety stop lever before the tool is
cleaned.
•In the case of machines with a cone clutch (505/506) stop the engine after ending the work
and set the clutch to the start position (see figure 2) so that the clutch cannot stick - due to
humidity.
Deactivating the safety stop lever by binding or taping down is prohibited.
The protective devices
Are installed to protect the operators and may not be changed or removed under any circum-
stances and may not be bypassed by making changes to the -2-wheel tractor.
The safety stop lever serves as an EMERGENCY-OFF SWITCH which should be released in
the case of hazardous situations which require quick deactivation. This then pivots automatically
to the position "STOP".

3.6 Shifting – forward/ reverse gear on the shaft
Warning!
A shifting procedure should only occur when the engine is running.
For all shifting procedures, the clutch must be fully pulled!
In the case of the -2-wheel tractor without differential locking forward and reverse shifting
with a switching handle on the lower right of the shaft is possible.
Design Gear box with or without differential locking on the right side of the shaft using the
deflection lever
Forward gear
Shift the forward gear as displaced in figure 9. Leave switching handle Ain the lower position
Reverse gear
For travel in the reverse gear, the switching handle Ashould be pulled completely down and
latched (see figure 9, right).
Setting of the forward and reverse gears
Depending on the stretching of the rope, an adjustment of the Bowden cable can be necessary af-
ter a few hours. In case the reverse gear can no longer be shifted, the setting screw must be
slightly loosened. Subsequently secure with counter nut.
3.7 Clutch
Caution!
Please observe that when shifting the gears (for forward and reverse travel and the switching on
and off of the implements) the clutch must always be pulled.
The clutch is activated with the clutch handle. Pulling the handle causes decoupling, i.e. the en-
gine no longer drives the machine - see figure 10.
In order to prevent the clutch from slipping during the work, a clearance is set at the factory on
the clutch handle. After the first hour of operation, the clutch clearance must be checked and
possibly reset. Adjustable by means of a setting screw on the clutch handle - see figure11.
Cone clutch: approx. 10 mm (must be screwed in so that a clearance exists)
Multi-disk clutch: approx. 10 mm (to allow for complete decoupling, the clutch must be
readjusted, so that not too much clearance is present.)
