SECTION 1: ASSEMBLY AND SET-UP Tractor Requirements The purpose of this manual is to assist in setting up, operating, and maintaining your backhoe. Read it carefully. It furnishes information and instructions that will help you achieve years of dependable performance.

Page 8: Mounting Instructions
CAUTION The tractor/backhoe must only be operated with all safety equipment properly installed. Tire Pressure Tractor tires should be maintained at maximum recommended inflation to maintain normal tire profile with added weight of backhoe/material. Unequal rear tire inflation can result in bucket not level to the ground. Backhoe mounting The following instructions will help you mount the backhoe to the tractor 3-point hitch. -
Page 9: Seat Adjustment
WARNING Until the backhoe is securely mounted onto the tractor, keep all people clear of your work area and make sure that no portion of the operator's body is beneath any part of the backhoe. 11. Raise the backhoe using the stabilizer and boom control levers until the swing is approximately 20 cm above ground level. Make sure the backhoe is vertical (perpendicular to the ground). -
Page 10: Section 2: Operating Instructions
models of tractors have standard category hitches and backhoes have standard category attaching points, it is possible to mount tractor/backhoe combinations that are not compatible. Dealers and/or owners must determine that compatibility between the tractor and backhoe exists. Compatibility includes but is not limited to items such as operator clearance, hitch component strength, tractor case strength and hydraulics. - Page 11 Starting operation When operating the backhoe, smoothness of technique should be strived for at all times. Smoothness will come with experience and practice at feathering the controls. Establish a flowing digging cycle to increase operator efficiency and save unnecessary wear on the machine.
- Page 12 swing the unit back to the excavation, positioning the bucket and dipperstick for the next cut in the process. The whole digging process should be one smooth cycle that is repeated unt 仆 the excavation is completed. When the excavation has been dug to within 15 cm of the finished bottom, clear and touch up the sides of the excavation.

Page 13: Special Applications
When digging a pipe leak, always dig along the line of pipe and never across it. Excavate around the leak to give ample room for the repair to be made. When trenching on a slope, always start at the top and work down. When working across a slope make full use of the stabilizers on the backhoe to level the machine. -
Page 14: Detaching Backhoe
under stabilizers could collapse. Make all movements slowly and gradually when practicing operation. Operate from backhoe operators' seat only. Pay attention; be ready to stop immediately in case of an emergency. To help prevent roll-over, adjust the rear wheels to their widest setting to maximize stability.

grease nipple is missing replace it immediately. Clean all joints before using grease gun. Avoid excessive greasing. Dirt collects on exposed grease and greatly increases wear. After greasing, wipe off excessive grease from fittings. When servicing your backhoe, remember to use only manufacturer replacement parts. Substitute parts may not meet the standards required for safe, dependable operation. -
Page 16: Lubrication
Do not perform service or maintenance operations with backhoe raised off the ground. For additional access to tractor components; remove backhoe.
