TRENCHER OPERATING INSTRUCTIONS
Drive the Loader to the attachment and couple the Attachment
Plate onto the attachment. Raise the Trencher slightly and engage
the locking pins fully. Turn the engine off and push the AUX
Control Lever forwards and backwards to release any hydraulic
line pressure. Clean the hydraulic fittings (QRCs) and then
connect them to connections A & C (see “Hydraulic Attachment
Connection” section).
Removal procedure is the reverse order of the above. Remember
to always reconnect the attachment hoses into one another to
stop dirt entering the hydraulic system, or fit the dust
caps supplied.
Ensure that the Trencher is securely attached to the Kanga
Loader. Check that the couplings are engaged and check all joints
for leaks. Tighten/repair as required. Inspect the cutting teeth,
ensuring that they are in good condition and firmly attached.
Chain Tensioning:
The Trencher chain requires 35-45mm of “lift” to have the correct
tension and should be adjust as required. This is achieved by
loosening the 16mm bolt, adjusting the adjustment wedge, and
retightening the bolt.
CAUTION: Read all safety rules before operating.
See safety chapter in this manual.
CAUTION: Prior to commencing any digging operations, check with the Local
Authorities and the land owner that there are no buried services (Power, phone, water,
gas, sewage etc) in the vicinity.
Australia ONLY: Phone 1100 “DIAL BEFORE YOU DIG”
Read the Safety instructions in this Manual.
Keep clear of the Trencher at all times (4m minimum).

PRE-OPERATION CHECK
OPERATING INSTRUCTION
SETTING TRENCHING VALVE
Position the Trencher, and activate the AUX lever so that the chain
runs along the top of the boom and returns back towards you on
the underside. Engage the TILT lever so that the boom and chain
arcs down to dig a trench. When the desired depth is achieved,
slowly drive the Kanga Loader backwards along the trench line.
(LH side of the Loader). This is a load-sensing valve, which can be
set to automatically regulate the speed of travel when trenching.
Use the black knob to shut off the valve (turn clockwise). With the
trencher cutting to the required depth start moving backwards
using the drive levers, open the valve (½ a turn) and this will
regulate the travel speed. Further adjustment of this valve will
vary the cutting speed to suit the conditions and the
operator’s experience.
NOTE: Minor adjustments are required to maintain a straight
line as the Loader will tend to “drift” to the left.
