Safety Warning Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death. The loader arms may lower when in the raised position after stopping the engine, crushing anyone under them.
Safety Decals # 99-9952 1. Cutting hazard, chain and auger—stay away from moving parts and keep bystanders away. 2. Warning—stop the engine and remove the key before preforming and maintenance or repairs. 3. Explosion and/or electric shock hazard—do not dig in areas with buried gas or power lines.
Installation Refer to your traction unit Operator’s Manual for complete instructions on installing attachments onto the traction unit and connecting hydraulic hoses. Loose Parts Note: A digging chain must be purchased separately and is required for this trencher. DESCRIPTION QTY. Trencher head 1 36 in. (91.4 cm) trencher boom (purchased separately—purchase a 36 in. (91.4 cm) boom for digging trenches more than 24 in. (60.9 cm) deep) 1 24 in. (60.
8. If the chain is not connected, connect the links by pressing or hammering the clevis pin supplied with the chain through the links. 2 4 Important To avoid bending the chain links, place blocks under and between the links when hammering the clevis pin through. 1 9. Secure the clevis pin with the cotter pin supplied with the chain. 3 10. Loop the digging chain over the auger drive shaft and onto the drive sprocket, ensuring that the digging teeth point forward on the upper span. m–5289 11.
• 6 in. (15 cm) chain configuration 2. Remove the plug from the bearing case fill hole (Fig. 7). Using the hole farthest from the auger blade in the end of the auger with two holes, connect the auger to the inner hole on the shaft. 3. Look in the hole, the level should be up to the bottom of the hole; if not add gear lube until it comes out of the hole. • 8 in. (20 cm) chain configuration 4. Replace the plug and torque it to 67 to 83 ft.-lb. (91 to 112 N⋅m).
10. Move the hoses from the hose guide on top of the trencher to the hose guide on the left side (Fig. 5). Warning Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result. Tips for Trenching • Clean the area of trash, branches and rocks before trenching to prevent equipment damage.
Maintenance Recommended Maintenance Schedule Maintenance Service Interval Maintenance Procedure 8 hours • Grease all fittings. • Check the teeth and replace any that are worn or damaged. • Tighten the bolt and nut securing the spoils auger. 25 hours • Adjust the digging chain tension. • Check the condition of the bearing case lube 200 hours • Change the bearing case lube. Storage Service • Grease all fittings. • Adjust the digging chain tension.
Servicing the Bearing Case Lube 2. Remove the plug from the bearing case fill hole (Fig. 7). 3. Lift the trencher until the boom is vertical, draining the lube through the fill hole and into a pan. Check the bearing case lube every 25 operating hours for dirt or other contaminants. Change the gear case lube every 200 operating hours 4. Return the trencher to the ground. 5. Fill the bearing case with gear lube until it comes out of the fill hole.
Replacing the Digging Teeth 8. Remove the six bolts securing the drive sprocket (Fig. 8). Due to the high amount of wear placed on the digging teeth, you will need to replace them periodically. 9. Remove and discard the drive sprocket (Fig. 8). 10. Clean the sprocket mounting surface on the trencher. To replace a single tooth, remove the bolts securing the tooth to remove it, then install a new tooth in the same position. Torque the bolts securing the teeth to 27 to 33 ft.-lb. (37 to 45 N⋅m). 11.
Storage boom you purchased, you will either have a chain with 24 links (24 in. (60.9 cm) boom) or 32 links (36 in. (91.4 cm) boom). Each link can have digging teeth fastened to it and is referred to as a tooth position. At each tooth position, the teeth are fastened in various configurations with spacers and tubes to vary the width of cut. The tooth configurations are placed along the chain in an order that maximizes digging efficiency. 1. Before long term storage, brush the dirt from the attachment. 2.
2. Lower the loader arms, stop the engine, and remove the key. 3. Remove the unneeded teeth and other hardware from the links on the top span of the chain. Note: When removing teeth, keep the components of each tooth set together so you can assemble them later. 4. Install each tooth set across the top span from front to back, in the order listed in the appropriate chain configuration table.
