  • Page 108: Topping Up Hydraulic Oil

    Maintenance Topping up hydraulic oil Pay attention to utmost cleanliness when servicing the hydraulic system. This service may only be carried out after the hydraulic oil has cooled down.  All hydraulic cylinders have to be extended half way (see figure), the boom has to be in line with the excavator, the dozer blade has to be lowered to the ground and the ex- tendable track width has to be set to standard track width.

  • Page 109: Working With The Battery

    Maintenance Working with the battery Battery acid is very caustic. Avoid contact with battery acid under all circumstances. If clothing, skin or eyes have come in contact with battery acid, rinse the affected parts immediately with water. If the eyes are affected, immediately seek medical attention! Neutralise spilled battery acid immediately.

  • Page 110: Charging The Battery

    Maintenance Charging the battery Charge batteries only in sufficiently ventilated rooms. Smoking, uncovered lights or fire are not allowed in these rooms. Explosive gas is created when charging batteries. Open flames can cause an explosion. Remove the fill caps when charging batteries that are virtually empty. Leave the fill caps inside (not empty) batteries that are only charged for maintenance purposes, the fill caps can stay in the batteries.
