Follow the instructions in the Engine Operators Manual for all maintenance of the engine such as
checking the oil, cleaning air filters, etc.

Use standard unleaded gasoline in the stump grinder engine.
BELTS
Check the condition and tension of the drive belts before each operation. When properly

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 toward from the cutter wheel.
Remove belt. Replace with new belt. Pull wrench handle away cutter wheel until proper tension
of 3/8" at 5 lbs. is attained. Hold wrench as you tighten the tensioner bolt and pivot bolt.
