If there is congestion in the path uphill, the vehicle tends to move down or backwards. Avoid tread clutch pedal 1 / 2 to maintain the vehicle so it will not move backwards. This will speed up Wear and tear canvas clutch. If this is not the possibility of clutch slip and the vehicle will not be running (strike).
How safe is pull the hand brake lever when the vehicle stops the vehicle so restrained. When will move forward / run, in the same time running a freelance gas pedal and clutch pedal while slowly release the hand brake lever. This allows the vehicle go slowly on the uphill path.
