Operation Instruction
⑴
Hydraulic motor displacement setting
This Mulcher attachment uses inclined shaft axial piston motor, the displacement of
motor is manually adjustable. Displacement limit adjustment range is 15.8-54.8ml/r, and the
limiting speed of the motor can be reached 5000r/min, but too high speed will reduce
attachment working life, so this mulcher requires motor maximum output speed not to exceed
3000 r/min
，
mulcher motor’s displacement adjustment range is adjusted to 30-54.8 ml/r in
Factory.
The best flow range of host machine to provide to mulcher is 80— 150L/MIN
，
if less
than 80L/MIN
；
mulcher work efficiency will be reduced
，
if more than 150 L/MIN
，
mulcher
vibration will be intensified, then mulcher work life will be reduced
。
If host machine flow is
more than 150 L/MIN
，
it should be considered to use the other larger displacement of
hydraulic motor
。
The ideal rotational speed of cutting drum (see product structure
instructions) is 1700-2000 r/min, in this speed range, the actual output.

Description of Equipment Capability
：
This mulcher model is used to clear high weeds, dense shrubs and trees with a diameter
no more than 200mm. The host machine pressure not more than 35MPa.
②
If mulcher uses on skid steer loader, please use high-flow tubing connection
。
Please note: Cutting drum rotational direction is unidirectional
，
If mulcher tubes connect
correctly
，
but cutting drum does not work, the engine of host machine needs to be idled until
the cutting drum is operated, otherwise it need to replace tubing connectors location
。（
Turn
off the host engine when replacing tubing connectors
）
③
After opening the hydraulic motor, gradually increase flow to improve required speed to
work, and ensure cutting drum speed is moderately during flow adjustment process.
④
Operate host machine to control mulcher both sides wearing plates touch with ground,
then operator control mulcher toward destination and working, so this can achieve the best
working results.
⑤
During operation, do not lift mulcher too high, so that the protection chain to lose the
protective effect on the operator, because cutting pieces are easy to hurt the operator.
⑥
Do not forward host machine too fast, because fast speed not only makes the hydraulic
system pressure of host machine too high, but also will make high fever.
⑦
If mulcher encounter obstacles in the work to be greater cutting force, but cutting drum
does not rotate, the operator should remove the mulcher from cutting things, and then restore
the cutting drum speed, adopt small cutting method for cutting the obstacles, and slow down
host machine speed .
⑧
For cutting thicker trunks, when cutting drum cuts off 3/4 of trunks, use front compressive
bar on the mulcher to touch with trunks, and then forward host machine to control front
compressive bar to force the trunks break, it can protect operator will not be hit by broken
trunk.
