MAINTENANCE POWERTEK ENGINE Follow the instructions in the Engine Operators Manual for all maintenance of the engine such as checking the oil, cleaning air filters, etc. FUEL Use standard unleaded gasoline in the stump grinder engine. BELTS Check the condition and tension of the drive belts before each operation. When properly tensioned, the belts should give a 3/8" deflection at the center span under approx. 5 lbs. of pressure.
MAINTENANCE POWERTEK SHARPENING CUTTERS The cutters should be sharpened frequently for higher performance and a longer life. It is also easier to grind them if they are ground often. *You will need a carbide-grinding wheel (green wheel) to sharpen them. Use a coarse grinding wheel to grind the steel shank. Be sure to maintain the back grind of 15 degrees (approximately). The cutters must be replaced when the tooth has been sharpened so that 1/4" (approximately) of the carbide is left. (Fig.
MAINTENANCE POWERTEK REPLACING CUTTERS (Fig. 9) Remember before you replace any cutters you must turn the engine off, wait for moving parts to stop, remove the key from the ignition and remove wires from spark plugs. 1. Put the handle in the transport position and tilt the Stump Grinder all the way back until it rests firmly on the ground. 2. To make cutter replacement easier, you can slide tensioner wrench handle through the hole in the cutter guard and cutter wheel.
