Set Up

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

RISK OF ACCIDENTAL STARTING RESULTING IN SERIOUS PERSONAL INJURY.

Turn the Power Switch of the equipment to its “OFF” position, wait for the engine to cool, and unplug the spark plug wire(s) before assembling or making any adjustments to the equipment.

The emission control system for this product’s Engine is warranted for standards set by the U.S. Environmental Protection Agency and by the California Air Resources Board (also known as CARB). For warranty information, refer to the last pages of this manual.

At high altitudes, the engine’s carburetor, governor (if so equipped), and any other parts that control the fuel-air ratio will need to be adjusted by a qualified mechanic to allow efficient high-altitude use and to prevent damage to the engine and any other devices used with this product.

Assembly

1. This equipment has a spark arresting muffler.

A spark arresting muffler is required by law in

California, on some US Forest Service land, and possibly in other areas or situations.

2. Due to the size of the Trencher and its components, assistance may be required during the entire assembly process.

3. Use jacks (not included) to evenly raise the Frame Assembly (90) & support with jack stands (not included).

4. Mount both Axles (50) near the boom end of the Frame and secure with Lock Pins (82).

5. Place a Tire (52) over the four studs on each

Hub. Secure the Tires to the Hubs, using four Lug Nuts (53) per Tire. The Lug Nuts must be snug. Inflate the Tires to 65 PSI.

6. Slightly raise the jacks, remove the jack stands, then lower the jacks. Block the Tires and tighten the Lug Nuts to at least 90 Ft-Lbs.

7. Attach Seat (73) to the Seat Bottom

Plate (10) and secure both Seat and Plate to the post on top of Hydraulic Oil Tank.

8. Attach the Control Support (3) to the Frame

Assembly (90) using four Hex Bolts (81).

NOTE: The Hydraulics of this unit are tested before shipment. There may be hydraulic fluid present in components. Assemble the unit in an area that will not be damaged by leaking hydraulic fluid. It is recommended that you wrap rags securely over the Hydraulic Connectors on all the Cylinders during assembly. Wear splashresistant ANSI approved safety goggles and other protective gear to prevent injury from leaking fluid.

9. Attach the Main Boom (36) to the Boom Pivot

(38) using the Pin (42) through the bottom hole and Clevis Pin No. 1 (29) through the upper hole.

Secure both pins with Hair Pin Clip (31); Pin (42) requires one Cotter pin on each end. See Figure A.

Assembly (90) under the Engine (74) using

Hex Bolts (75) and Hex HD. Bolt (72).

12. Connect, tighten, and check all hydraulic hose fittings to the proper connections, as shown in the Hose Connection Diagram. Hoses and fittings are numbered. Tighten all fittings.

13. Open the Hydraulic Fluid Fill Plug (11). Top off the Hydraulic Fluid Reservoir with high quality hydraulic fluid. Check that the fluid level is between the lines on the attached Dipstick.

Attaching the Leg Assembly

1. To use the Trencher, the Leg Assemblies must be installed next to the Boom (36), and the

Wheels and Axles (50) moved to the rear.

2. Move the Trencher to the work area (See

Starting the Engine on page 10).

3. Start the engine and use the Boom Controls to curl the Bucket toward the Boom without touching the ground. Moving the Bucket As sembly (32) down to the ground will raise the Frame Assembly (90).

Lift the Tires just off the ground and stop.

4. Ensure the controls will not be touched or bumped, and that the Trencher will remain motionless. Never place any part of your body under the Trencher.

Purging the Cylinder

1. Remove all Safety Locking Pins (15), disengage the Safety Latch (41) and loosen Hydraulic Tank Fill Plug (11).

2. Press forward on the Boom Swing Lever

(located on Control Panel (9) until the Boom stops moving, then pull back on it until it moves in the other direction. Center the Boom.

3. Press forward on the Main Boom Lever until the Main Boom is fully raised. Then, press Forward on the Boom Extension

Lever until the Boom is fully extended.

5. With the Tires (52) off the ground, remove the

Wheel and Axle (50) to the operator’s left and replace with the left side Extension Leg (19) and

Leg Assembly (24). Direct the Extension Leg so it turns toward the Bucket end of the Trencher.

Secure with Lock Pin No. 2 (82). Repeat procedure for the right side. Raise Bucket As sembly again to lower onto Leg Assembly, and turn Engine off.

6. Using a jack and jack stands (not included), raise up the engine end of the Trencher and disconnect from the Towing Hitch. Slide the Wheels and

Axles (50) into the engine end of the Frame (90).

Secure each Axle with Lock Pin No. 2 (82).

4. Press forward on the Bucket Lever until the Bucket is fully extended. Pull back on the Lever to retract it fully.

5. Pull back on the Boom Extension Lever until the Boom is pulled back all the way.

Pull back on the Main Boom Lever until the Main Boom is lowered completely.

6. Adjust the Boom back to its rest position and replace all locking devices.

7. Shut off the Engine, check the Hydraulic

Fluid level and refill as necessary.

Note: The Fill Plug is vented. When tightening the

Fill Plug, tighten it securely then back it off slightly.
