DANGER WARNING POTENTIAL HAZARD • Contact with moving teeth and auger may cause injury. POTENTIAL HAZARD • When the engine is off, attachments in the raised position can gradually lower. WHAT CAN HAPPEN • Moving teeth and auger can cut hands, feet or other body parts. WHAT CAN HAPPEN • Someone nearby may be pinned or injured by the attachment as it lowers. HOW TO AVOID THE HAZARD • Keep away from the moving teeth and auger while operating the trencher.
Stability Ratings WARNING To determine the degree of slope you can traverse with the trencher installed on a traction unit, find the stability rating for the hill position you want to travel in the table below, then find the degree of slope for the same rating and hill position in the Stability Data section of the traction unit operator’s manual. Orientation POTENTIAL HAZARD • Exceeding the maximum slope can cause the traction unit to tip.

On the end of the adjustor with the flush adjustment nut (Fig. 5), make a mark across the face of the nut and adjustor. This will enable you to determine the exact position the nut should be in when you install it later. 5. Raise the loader arms while tilting back the mount plate at the same time.
• 4” chain configuration 12. Secure the clevis pin with the supplied cotter pin. 13. Loop the digging chain over the auger drive shaft and onto the chain drive sprocket, ensuring that the digging teeth will point forward on the upper span. Using the hole closest to the auger blade in the end of the auger with two holes, connect the auger to the inner hole on the shaft. • 6” chain configuration 14.
Connecting the Hydraulic Hoses Removing the Trencher from the Traction Unit 1. Start the engine and lower the trencher to the ground or onto a trailer. WARNING 2. Stop the engine. POTENTIAL HAZARD • Hydraulic fluid escaping under pressure can penetrate skin and cause injury. 3. Disengage the quick attach pins by turning them to the outside. WHAT CAN HAPPEN 4. Slide the collars back on the hydraulic couplers and disconnect them.
• When trenching, the spoils auger should just clear the original ground surface to obtain maximum soil removal. Tips for Trenching • Clean the area of trash, branches and rocks before trenching to prevent equipment damage. • Trench at a 45 to 60 degree angle for best results. • Always begin trenching with the slowest ground speed possible. Increase speed if conditions permit. • You will be able to dig a trench faster by controlling the depth with periodic adjustments of the loader arms.
Greasing and Lubrication Adjusting Digging Chain Tension Service Interval/Specification Adjust the digging chain every 25 operating hours. With the trencher parallel to the ground, ensure that there are 3 inches between the bottom of the boom and the top of the bottom chain span. If there is more than 3 inches, adjust the chain using the following procedure: Check the gear lubrication oil level in the planetary gear case before the first use,and then every 25 operating hours.
Reconfiguring the Digging Chain There are two types of teeth, cupped and triangular rock teeth. Cupped teeth are designed to cut through and remove soil. Triangular rock teeth cut rock and other hard ground. The teeth are cupped or angled differently depending on which side of the chain they are intended to be fastened (i.e., either left or right). The chain can be set up in different configurations, depending on the width of the trench desired and the soil conditions at the work site.
