OPERATION INSTRUCTIONS
The trencher can dig a trench with 900mm depth and 200mm width. Attach the
trencher to the toolbar or quick attach mechanism of your skid steer loader.
RAISING OR LOWERING THE TRENCHER
raise or lower the trencher by raising or lowering the skid steer loader arms
through their appropriate skid steer controls.
TILTING THE TRENCHER
Tilt the trencher up or down by tilting the toolbar or attachment plate back or
forward through its skid steer controls. We recommend a 60 degrees angle for
general trenching as measured from the ground level(the horizon).
STARTING AND STOPPING THE TRENCHER
Power to the trencher is supplied by oil from the skid steer auxiliary hydraulic
system, which passes through the hydraulic hoses and into the trencher's
hydraulic motor. The trencher itself has no one on or off control, but is
operated by the skid steer auxiliary hydraulic control mechanism. To start the
trencher, engage the auxiliary hydraulics. To stop the trencher, disengage the
auxiliary hydraulics.
TRENCHER SPEED CONTROL
The power of the trencher is supplied by the skid steer's auxiliary hydraulics.
Trencher speed and power are determined by the flow of oil coming out of the
auxiliary system, which in turn is dependent upon skid steer engine speed. To
increase trencher speed, increase skid steer engine speed, on the contrary, to
decrease trencher speed, decrease skid steer loader speed.
When first starting a trench throttle down the skid steer engine to half throttle.
This will reduce the shock to the skid steer and trencher when the digging
teeth first contact the ground. Once the trench is started, set the engine back to
the full throttle. For the general use, operate the trencher with skid steer engine
at full throttle to provide maximum power to the auxiliary hydraulics.

OPERATION INSTRUCTIONS
AUGER HEIGHT
The auger is fixed to the trencher mainframe and has no separate adjustment.
To raise the auger, raise the trencher as previously described. This will raise
the auger to leave the dirt or spoil closer to the trench.
CHAIN TENSION ADJUSTMENT
When trenching, the digging chain tension should be adjusted to let the chain
is as loose as possible, without jumping off the sprocket or Idler wheel. In the
left of the trencher arm end, should have an adjustment bolt with a jam nut, to
tighten the chain, need rotate the adjustment bolt to the proper position, and
turn the standard nut to the adjustment bolt, will push the boom out and thus
tighten the chain. To loosen the chain, just use the opposite method.
NOTE 1:
It is common for your trencher to need its digging chain tightened after the first
10 to 20 minutes of operation as the chain and sprocket seat themselves.
NOTE 2:
Don't trench stones or hard soils, to prevent damage to the digging teeth of the
trencher. If the digging teeth wear severely, should replace them timely, to
ensure the normal work.
