Daily Checklist for the DR 6.25 TOW-BEHIND TRIMMER/MOWER 

To help maintain your DR 6.25 TOW-BEHIND TRIMMER/MOWER for optimum performance, we recommend you follow this checklist each 
time you use your machine. 

[  ]  OIL:  With the machine on a level surface, check the Engine oil level with the Dipstick and add more if necessary (only add oil to the level 

indicated on the Dipstick - do not overfill). Use SAE 30 high detergent motor oil. 

[  ]  GAS:  Fill the Fuel Tank with clean, fresh, unleaded gasoline. 
[  ]  ENGINE AIR COOLING SYSTEM:  It is very important to keep the Engine clean of debris.  Remove grass and other built-up materials 

from the Air Intake Screen before, during, and after you mow.  Regularly remove debris from the Blower Housing and Cooling Fins.  A 
dirty Engine retains heat and can cause damage to the internal Engine parts. 

[  ]  CUTTING CORDS:  Replace broken, frayed or missing Cords. 
[  ]  GENERAL CONDITION:  Check the general condition of the machine, e.g.; nuts, bolts, welds etc. 
[  ]  MOW-BALL® and Line Plates:  Check the Mow-Ball® and Line Plates for wear or damage and replace as needed. 
[  ]  TIRE AIR PRESSURE:  Check the air pressure in the Tires and adjust as needed. 

End of Season and Storage 

 

Change the Engine oil.  This will help to eliminate sludge and acids in the Engine. 

 

Lubricate Swivel Frame and Tracking Wheel Grease Fittings. 

 

Check the Drive Belt for wear. Replace as needed. 

 

Release Drive Belt from Tensioner to relieve Belt stress. 

 

Check the general condition of the machine, e.g.; nuts, bolts, welds, etc. Replace parts or tighten Hardware as needed. 

 

Store in a dry covered area to protect from moisture. 

 

Remove any wrapped weeds from the Trimmer Head and Wheel Assemblies.  Clean grass and debris from the top and underneath the 
Trimmer Frame. 

 

Remove the Spark Plug and pour about 1 ounce of motor oil into the cylinder hole.  Reinstall the Plug and pull the Recoil Starter Rope 
until you feel strong resistance.  This will coat the piston and seat the valves to prevent moisture buildup. 

 

Clean or replace the Engine Air Filter. 

 

Clean any dirt and debris from the cylinder head cooling fins, carburetor linkage, blower housing, debris screen, and muffler area of the 
Engine. 

 

If your DR TRIMMER/MOWER 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. 

Shut off the Tow Vehicle, set the parking brake and remove the Key.  Shut off the Trimmer Engine and after all moving parts to 
come to a complete stop, wait five minutes for the machine to cool and disconnect the spark plug wire, keeping it away from the 
spark plug before performing any maintenance procedure or inspection on the Trimmer.
