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. 15 lbs. of pressure.

CUTTER BELT REPLACEMENT

If the belts are excessively warm or can no longer be properly tensioned, they must be replaced. Use a 2A94 size
belt when replacing the belt. To remove cutter belt, lightly loosen the tensioner bolt and the pivot bolt on the
backside of the belt cover in front of the engine. Place tensioner wrench between the two tension bolts. Push the
wrench handle away from the cutter wheel. Remove belt. Replace with new belt. Pull wrench handle toward cutter
wheel until proper tension of 3/8" at 15 lbs. is attained. Hold wrench as you tighten the tensioner bolt and pivot bolt.
Replace belt cover. See fig. 6 & 7.

HYDROSTATIC DRIVE BELT REPLACEMENT

To remove hydrostatic drive belt, remove cutter belt as described above. Loosen the clutch bracket and remove.
Loosen idler pulley and slide forward. Remove belt. Replace with a new AX-35 belt. Replace belt over clutch
pulley, hydro pulley, and idler pulley. Slide idler pulley until belt is tensioned to 3/8" at 15lbs. Tighten idler pulley.
Replace clutch bracket and re-tighten. Replace cutter drive belt as above. Replace belt cover. See fig. 7.

HOUR METER

The meter is fully automatic with a display that may be read at all times, whether the engine is on or off. During
running times, engine RPM is shown; after shut down, Accumulated Running Time is shown.
After 25 hour of running time, the meter will automatically blink as a signal for oil change. It will continue to blink
for a (2) hour period of accumulated running time (ie., 25 to 27 hours). The next alert will automatically appear in
25 hours. No re-set is required.
