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. • Check the boom for wear. 200 hours • Change the bearing case lube. • Grease all fittings. • Adjust the digging chain tension. • Paint any chipped surfaces.
Adjusting the Digging Chain Tension Checking the Bearing Case Lube 1. Clean the area around the gear case fill hole plug (Fig. 3). Adjust the digging chain every 25 operating hours. With the trencher parallel to the ground, ensure that there are 1-1/2 to 2-1/2 inches (4 to 6 cm) between the bottom of the boom and the top of the bottom chain span. If not, adjust the chain using the following procedure: 1 Important Do not overtighten the chain. Excess chain tension may damage drive components. 1.
13. Thread the adjustment bolt into the boom and turn it in until there is 1-1/2 to 2-1/2 inches (4 to 6 cm) of slack in the chain on the bottom span. 2. Loosen the 2 bolts and nuts securing the boom to the trencher arm (Fig. 4). 3. Loosen the jam nut securing the adjustment bolt (Fig. 4). 14. Thread the jam nut down the adjusting bolt and tighten it securely against the boom. 4. Turn the adjustment bolt in or out as needed to achieve the desired tension. 15.
15. Set the upper span of the chain into place on the trencher boom, then wrap the chain around the roller at the end of the boom. 16. Thread the adjustment bolt into the boom and turn it in until there is 1-1/2 to 2-1/2 inches (4 to 6 cm) of slack in the chain on the bottom span. 17. Thread the jam nut down the adjusting bolt and tighten it securely against the boom. 2 18. Torque the 2 bolts and nuts securing the boom to 135 to 165 ft-lb. (183 to 223 N⋅m). 1 19.
