OPERATION
2.3 OFF-ROAD DRIVING
Safe o-road driving largely depends on the operator’s experience and judgement. Familiarise yourself with the machine and practise
driving your Alstor on easy terrain and rm ground. The machine should normally be operated with the dierential lock disengaged =
notactivated. NOTE: When engaging/disengaging the dierential lock, the machine should be stopped. Wait 4 seconds after operating
the dierential lock and then move the steering wheel alittle before you continue driving.
WARNING! On steep hills and slippery surfaces, the dierential lock should always be engaged as aprecautionary measure.
■
Take the necessary precautions when driving up or down steep slopes. Drive straight up and straight down in 1st gear.
■
When driving downhill with engine braking, please see the section “Braking”. Always select asafe route.
■
Never drive uphill or downhill on slippery or lose ground.
■
Never engage the dierential lock on machines with steel crawler tracks regardless of the surface.
■
When driving on frozen lakes/waterways, always remove the door and open the window.
■
Avoid driving across steep hills. There is arisk that the machine could overturn.
■
Never turn on steep uphill or downhill slopes. There is arisk that the machine could overturn.
■
When driving, always try to position obstacles (stumps, stones, etc.) under the wheels.
■
Navigate past obstacles at low speed.
■
If wheel pairs start slipping in rough terrain: Stop the machine, press the button to engage the dierential locks, wait 4 seconds and
then move the steering wheel alittle before driving o again. Once you have cleared the obstacles/dicult terrain, stop the machine,
press the button to disengage the dierential locks, wait 4 seconds and move the steering wheel alittle before you continue driving.
WARNING! If you feel the machine is about to overturn, jump o on the uphill side – never on the downhill side. Switch o the
ignition key and the main power switch. If possible, secure the machine and call for assistance. Never walk on the downhill side
ofthe machine as this is associated with mortal danger.
■
If only the rear section of the machine overturns, it is possible to tip the rear section back to its normal position.
Check to see whether anything is damaged, and remedy any faults immediately. If no damage is detected, continue with your
work/route.
■
If the front section of the machine overturns, pay special attention and check for any leaking uids (fuel, oil, etc.).
WARNING! Fuel leakage can cause are.
■
If the front section has overturned, request an inspection from an authorised workshop before using the machine again.
■
Alstor machines can navigate through water up to adepth of 37 cm. Carefully check that the water is not too deep or is owing
toorapidly. This is associated with danger. Always take great care.
■
Watch out for hidden obstacles and slippery stones in the water.
■
Keep in mind that when driving through water, the variator can slip and the brake function can be impaired. Apply the brake several
times until the brakes have dried and operate normally.
