10. Safety measures at the place of work
• When starting the engine, the traction and attached device drives must be disengaged (i.e.
the safety stop lever is not depressed; see fig. 2, page 12).
• The driving speed must be always adapted to the environmental conditions. Avoid sudden
turns when driving up, down or across a slope. Never disengage the clutch and/or shift gear
on slopes.
• Couple trailers and attached devices according to the regulations. The driving, steering,
braking capability and tipping behaviour will be affected by attached devices. Therefore
make sure that steering and braking capabilities are sufficient and adapt your working
speed to the respective environmental conditions!
• Persons fitted with a cardiac pacemaker must not touch electrically conducting parts of the
ignition system when the engine is running.
• Before starting to drive, check the brakes and their function.
• Remove larger objects from the work area (e.g. planks, cables, stones etc.).
• Keep hands and feet away from moving parts during operation.
• Ensure that the work area is sufficiently well illuminated.
• Drive at a right angle to the slope, never up or down the slope!
• Be particularly careful when changing direction on the slope.
• Never leave the operator position during work.
• Do not alter or repair supporting and safety-relevant parts (frame, axles etc.).
• In the case of damage to the appliance, switch it off immediately. Remove the spark plug
cap and have the damage repaired!
• If the appliance is to be used for mowing crops that are classified as foodstuffs, parts which
come into contact with the foodstuffs must not be lubricated with machine oil or grease or
protected against rust.
• If there is a danger of slipping on a sloping terrain, an accompanying person must hold the
2-wheel tractor with a rod or a rope. The accompanying person must remain above
the vehicle at a safe distance from the working tool.

11. General safety instructions
• Watch out for fuel and oil leaks and eliminate them if necessary.
• Check screws, nuts and bolts regularly for tightness and tighten them if necessary – after
the first time of use and if circumstances demand.
• Lubricate all sliding or moving parts (e.g. shift rod joints, Bowden cables etc.) with a little
grease or lubricating oil, especially after cleaning with a high pressure cleaner.
12. Protective devices
The 2-wheel tractor is equipped with a clutch/safety stop lever on the steering shaft (left),
which disengages the drive via the clutch when released – the engine continues to run. The drive
and the clutch are switched off (see fig. 2 - page 12).
The clutch/safety stop lever serves as an emergency stop switch in dangerous situations where
fast switch-off is required. It swivels automatically into the ‘STOP’ position when released.
It is locked there and can only be actuated when the catch is pressed. Stop the 2-wheel trac-
tor immediately if there are any malfunctions with the clutch/safety stop lever. Have the
malfunction rectified immediately!
Caution!
The engine runs on due to the centrifugal mass!
• The clutch/safety stop lever must be depressed (operating position) during operation.
• It is forbidden by to leave the clutch/safety stop lever in the start position (cou-
pling/safety stop lever is not depressed) when the machine is to be cleaned – e.g. in order to
clean the snow hoe. Bring the machine to a standstill only by switching off the engine, and
only then clean the tool.
It is forbidden
to tie the clutch/safety stop lever down or to bind it with adhesive tape!

Operation
Operation
In order to avoid damage to the machine and life-threatening injuries when putting the
machine into operation, it is essential to pay attention to the following points:
You must have read and understood
• the chapter ‘General safety instructions’
• the engine manufacturer’s operating manual
• the operating manual for each attached device
You may not operate the 2-wheel tractor before having done so.
1. Commissioning
Warning!
Exhaust gases contain carbon monoxide!
They are highly toxic if inhaled and can lead to death.
Important!
During the first 20 hours of operation (the running-in period) the engine should not be op-
erated up to its performance limit.
After about 10 hours of operation, check that all screws, bolts and controls on the basic
machine and attached devices are tight.
The following items must be checked before putting into operation for the first time:
• Check the engine oil (refer to the engine manufacturer’s operating manual).
• Check the gearbox and hydraulic oil.
• Check all safety devices.
• Check the fuel level in the fuel tank.
• Check that all screws, bolts and controls on the basic unit and attached devices are tight.
• Remove all tools and foreign parts from the machine.
• Adjust the steering shaft to the operator’s body size and in accordance with the purpose of
use.
2. Starting
Warning!
If the traction and device drive is engaged, you could be run over, causing serious injuries.
The traction and device drive must be disengaged when starting the engine.
Do not stand with your feet near the attached working device.
Please observe the following instructions when starting the tractor:
Turn the engine switch to the ON position and start the engine without depressing the
clutch/safety stop lever (see fig. 2, page 12). The twist-grip must always be in the 0 position.
In the case of Easy-Drive the green LED on the rocker switch must light up when the en-
gine is running.
Follow the respective engine manufacturer’s operating manual when starting the engine –
start it according to the engine manufacturer’s operating manual. Once the engine is running,
bring the throttle lever to the middle position and allow the engine to warm up for a short time.
At temperatures under + 5° C you must allow the hydraulic drive to warm up for approx. 3 min-
utes at a low engine speed so that the oil can reach operating temperature and the drive can func-
tion without problems. The twist-grip must thereby be in the 0 position and the clutch/safety stop
lever must be depressed, otherwise the oil pump will not run and the oil cannot warm up. Push

gerous situations can develop.
Switching the engine off: first release the clutch/safety stop lever
and then switch the engine off.
Important!
Please note that the clutch must always be disengaged in order to switch the power take-off
(switching working devices on and off). The same also applies if you are working with the
hoe and want to drive in reverse. First release the clutch/safety stop lever, turn the twist-
grip to the 0 position and switch off the power take-off! The latch must on no account be
disabled. The safety stop lever must be replaced immediately in the event of a defect.
The clutch is actuated via the clutch/safety stop lever.
If the clutch/safety stop lever (see fig. 12, left) is not depressed, the engine does not propel the
machine any longer and the hydraulic drives as well as the power take-off are interrupted.
In order to drive, you must depress the clutch/safety stop lever (fig 12, right).
If the clutch/safety stop lever is released, the machine stops moving. The engine continues to
run.
