Daily Checklist for the DR STUMP GRINDER
To help maintain your DR STUMP GRINDER for optimum performance, we recommend you follow this checklist each time
you use your Stump Grinder.
[ ] Check the engine oil and Gas Tank level.
[ ] Check that Engine is clean of debris.
[ ] Check the general condition of the Stump Grinder, e.g.; nuts, bolts, welds, etc.
[ ] Check Belt for wear and/or stretching.
[ ] Check Tire Pressure and wear.
[ ] Check the Teeth for wear and damage.
[ ] Check the Frame for wear and damage.
[ ] check the Debris Guard for wear and damage.
[ ] Remove any debris wrapped around the Cutter Head for Bearing protection.
End of Season and Storage
 Change the engine oil.

Clean or replace the Air Filter.

Check the teeth for wear and damage.

Remove any debris wrapped around the Cutter Head

If your DR STUMP GRINDER will be idle for more than 30 days, we recommend using a gas stabilizer. This will prevent
sediment from gumming up the Carburetor. If there is dirt or moisture in the gas or tank, remove it by draining the tank.
Completely fill the tank with fresh, unleaded gas and add the appropriate amount of stabilizer or gasoline additive. Run the
Engine for a short time to allow the additive to circulate.

Clean the exterior of the unit to remove all dirt, grease, and any other foreign material. To prevent rust, touch up painted
surfaces that have been scratched or chipped.
 Be sure all nuts, bolts, and screws are securely fastened.

Inspect moving parts and the Drive Belt for damage and wear; replace if necessary.

Remove the Spark Plug(s) and pour about 1 ounce of motor oil into the Cylinder hole. Replace the Plug(s) and crank the
Engine over a couple of times using the Pull Cord, or the Electric Starter (for Electric Start Machines). This will coat the
piston and seat the valves to prevent moisture buildup.

If possible, store the Stump Grinder in a dry, protected place. If it is necessary to store the Stump Grinder outside, cover it
with a protective material (especially the Engine). For Electric Start Model, store the machine in a dry environment with
temperatures between +40(degree symbol)F (5C) and +95F (+35C). Make sure the storage temperatures will never be
outside of these limits. The lower the storage temperature is within the specified temperature, the better as the battery will
discharge more slowly at low temperatures. If it is necessary to store the Stump Grinder outside make sure to disconnect
the battery and store it in an environment as listed above. Make sure the disconnected battery terminals are not resting on
any surface that may be prone to collecting water, snow or any other liquid as this may cause damage to the terminals and
to the battery when reconnected.
Before performing any maintenance procedure or inspection, stop the engine, wait five (5) minutes to allow all parts to cool.
Disconnect the spark plug wire, keeping it away from the spark plug.
