ROTARY HOE OPERATING INSTRUCTIONS
FITTING THE BACKHOE
CAUTION: Prior to commencing work, read the
Safety Rules of this Kanga Loader Manual.
1. Connect the attachment plate of the loader to the rotary hoe
frame. Check to confirm that the quick hitch attachment
locking pins are engaged. Turn the engine off and push the
AUX lever forward and backward to release any hydraulic
line pressure. Clean the hydraulic fittings (QRCs) and
connect rotary hoe hoses to connections A and C. (See
“Hydraulic Attachment Connections.”) Connect the hose
bracket to the machine and secure the R-clip.
2. To remove, reverse the order given above. To prohibit dirt
from entering the hydraulic system, always reconnect the
attachment hoses into one another or fit with supplied dust
caps.
1. Complete a pre-operation check. Confirm that the rotary
hoe is securely attached to the loader and the couplings are
engaged. Check all joints for leaks. Tighten and repair as
required. Check that the rotary hoe and cutting blades are in
good condition.
2. Place the AUX lever in neutral. Start the engine and adjust
engine RPM lever to suit the operation power required.
Position the rotary hoe flat on the ground. Engage the AUX
lever, pulling towards the operator. The hoe blades will begin
rotating.
NOTE: The rotary hoe should only be pulled with the
loader drive system. Do not push the rotary hoe.
OPERATING INSTRUCTIONS
CAUTION: Establish and maintain a minimum 4m exclusion zone around the working
area. No person other than the operator should enter the work zone while the machine’s
engine is running. Observe all underground utility markings carefully. Maintain a no-
work zone six feet from any utility marking. Do not place hands, feet, or other body part
or object near or under the rotary hoe for any reason. Never carry out maintenance of
any type on the rotary hoe while it is attached to the loader or other power source.
SET TRENCHING VALVE
FOR ROTARY HOE USE
The trenching valve is located on the left hand side of the loader.
This is a load-sensing valve and can be set to automatically
regulate the speed of travel when using a rotary hoe. Use the
black knob to shut off the valve, turning clockwise. With the rotary
hoe at the required depth, travel in reverse using the drive levers,
and open the valve (black knob) counter clockwise to regulate the
travel speed. Further adjustment of this valve will vary, depending
on cutting speed, conditions, and operator’s experience.
Adjust the travel speed of the loader to achieve the required
condition of the soil. For example, slower travel speed will turn the
soil over more, resulting in softer soil, and faster speed will turn
the soil over less, resulting in a chunkier soil texture.
