Hydraulic pump drive

Loosen four nuts of the fixing bolts holding the pump on the frame
uniformly approximately by 0,5 turn to let the pump slide in the intended
direction by means of the stretching bolt. Having reached the recommended
belt slack value, retighten the fixing bolts on the frame and the lock nut on the
stretching bolt. To make all the bolts accessible first it is necessary to remove
the belt guards over the belt pulley of the chipping wheel shaft.
Having finished the belt tension adjustment, replace the belts
guards.
Hydraulic oil filter change
The oil filter is installed in the hydraulic circuit and accessible left under the
loading chute.
We recommend changing the oil filter element always together with the hydraulic
oil change. This oil filter element is in fact a replaceable cartridge fixed on the
central bolt of the filter body. For its exchange it is necessary first to loosen it by
means of a special wrench.
Before filling new oil first screw up a new filter element.
Fill the hydraulic oil tank up to 17 litres only (up to the MAX mark on the oil
tank).
It is strictly forbidden to put this chipper into operation without
any oil filter or with its filter element clogged or damaged.
Replace the filter element only at stillstand of the machine.
Hydraulic oil temperature should be lower than 45
