Manure spreader MKL

Condensate shall be removed from the reservoir by pressing the drainage valve. Once a year, before
the winter season, the drainage valve must be screwed out and cleaned.
7.2.2 Adjustment of the elements of the pneumatic brake system
During the use of the manure spreader, it is necessary to check the efficiency of the brakes and
periodically lubricate the marked points.
The adjustment of the brakes shall be performed when:
•
the brake blocks are worn-out. The space between the brake blocks and drum increases, causing
the impairment of braking efficiency;
•
the wheels are braked not simultaneously and not uniformly.
When the brakes are adjusted correctly, the braking force (the sum of braking forces acting upon the
wheels being braked) should account for min 27 % of the permissible total mass of the manure spreader
when braking with the working brake, and the braking force (the sum of braking forces acting upon the
wheels being braked) should account for min 16 % of the permissible total mass of the manure spreader
when braking with the hand-brake. Both wheels of one axle should brake uniformly. The difference of the
braking forces between the left and right sides of the manure spreader should not exceed 30 %.
The adjustment of the brakes shall be performed only after the adjustment of the bearings of the
wheel hub, by changing the brake shaft's brake lever torque or angle of the brake lever in respect of the
shaft. For this purpose, it is necessary:
•
place protection wedges (blocks) under the wheel opposite to the one being adjusted;
•
insert a jack under the axle, at the marked place, and lift the wheel;
•
while rotating the wheel, also turn the adjustment bolt 4 (Fig. 7.15) until the braking blocks touch
the drum.
The moving distance (motion) of pneumatic brake chamber connector should be 60 - 65 mm, and the
difference between the force of the chamber connectors of all the wheel chambers should be not more
than 5 mm.

When changing the position of the handles of the braking force regulator, under the full load of the
manure spreader, it is necessary to ensure complete air supply to the pneumatic brake chambers.
After adjusting the working brake of the manure spreader, it is necessary to adjust the hand-brake. For
this purpose, the length of the cable 7 (Fig. 7.15) connecting the brake lever with the tension mechanism is
changed.
ATTENTION!
Constantly check the operation of the braking mechanism. When necessary, adjust or repair it. The
brake blocks must be checked once a year and be replaced worn-out brake blocks with new ones. After
the motion parts work in, re-adjust them.
