The articulation also allows the grader an action of self recovery in different
conditions.
3. Further applications of the grader can be realized by installing the following
equipment:
a) Back scarifier;
b) Front bulldozing plate ;
c) Towing attachment, rear;
d) Extra balance weights, front and rear.
4. An important factor for the optimal efficiency of the grader is the choice of
correct turning and cutting angle of blade. We recommend a relatively large turning
angle is used and thus a high cutting pressure is got in working length of pre cm.
Small cutting angle decreases the cutting resistance in cutting operation. Large cutting
angle is increases the leveling and mixing effect.
5. The front wheel should be leaned towards the side from which the material is
running off. When working on slopes, the front wheel can be set vertically to give
better traction with the aid of the wheel lean.
6. By acting the blade side-shift the blade can be moved out during grading
without the changing the operating height.
7. The grader should not be used underground or in badly ventilated area because
the engine is of the direct injection type and special filtering of the engine exhaust is
not enough.
8. Care and maintenance
8.1 Safety rules
Notes:
1. Set the grader on the level and hard ground.
2. Set the operating devices (including blade, bulldozing plate, etc) on ground.
3. Engage the hand brake tightly.
4. Insert the safety lever and fix the articulated steering mechanism of
grader(Fig.28).
