7 Operation Continued
How to Grind Stumps
Align the cutter wheel with the left side of the stump (viewed from the machine control area) and position the machine so that it will cut about 4-6 inches off the top of the stump and 8-12 inches from the left side of the stump. See FIGURE A.
The torsion mechanism prevents overloading of the carbide tipped cutting wheel, ensuring that grinding never stops. The rate of cut will depend on the type of tree, condition of the wood, and the condition of the cutters. Too light a feed will produce sawdust. The ideal feeding rate produces heavy wood chips, some of which may be about 1/16” thick by approximately 6-8 inches long, as well as chunks of wood. After completing the first cut through the stump, move the machine to the right (again as viewed from the control area) so the wheel can cut another 8-12 inches. Proceed with anther cut. Additional passes, when the tree stump is very large, are made in the same manner as described above. Repeat the procedure until the stump is cut to ground level.
Before cutting below the ground level, make certain that all rock or stone is removed from the immediate area of the cutting wheel. When you are cutting below the ground level, the feed rate should be reduced and the operator should be alert to the possibility of cutting hidden rock. Extra care used in this part of the operation can avoid costly damage to the cutting wheel and teeth.
The wheel is designed so that it can “saw” or cut its way into solid wood by dropping straight down on it. This operation works well for cutting off large roots.
NOTE: DO NOT operate the Stump Grinder with safety guards removed.
8 Maintenance
NOTE Cutting Wheel Disconnect the hydraulic connection Be certain to check carbide cutting teeth for wear. Standard between the attachment and the prime teeth can be rotated 180° for a fresh cutting edge. Sharpen mover before performing any type of or replace teeth as necessary. maintenance on the Stump Grinder. Hoses Check hoses occasionally for abrasion damage. This may save you from downtime. If in doubt, replace with genuine Blue Diamond Attachment parts.
Pivot Pins Pivot pins may be lubed with moly-type grease, same as what is used on your machine. Please check the cotter pins that retain all pivot/anchor pins after each use. If missing, replace! Severe damage could be caused by losing a pin.
Direct Drive System Check the direct drive system occasionally for seal damage and oil leaks. In the event of seal damage, replace the seal and the oil. To replace the oil, use 5 oz. of 90W gear oil. The oil can be added with just one plug out, but taking the second plug out allows it to vent and fill faster. Alternately, you can pour it in from the back with the motor off.
Storage Lubrication of pivot pins is recommended if unit is stored outside. Be certain hydraulic quick couplers are cleaned and joined together to keep dirt out. A light coating of oil film or diesel fluid is recommended to prevent corrosion. Touch-up paint should be used on all scratches to prevent further rust.
