Gearcase Maintenance
(Straight Shaft Model Only)
The gearcase should be checked for lubrication after each
30 hours of use (Fig. 28)
Remove the cutting attachment and the boss adapter.
Clean any dirt and debris from the area between the boss
adapter and the gearcase. Remove the grease plug from
the side of the gearcase. While rotating the attaching
shaft, inject lithium-base bearing lube through the plug
hole until the gearcase is full. Reinstall the gearcase plug
and boss adapter.

General Cleaning and
Tightening
POTENTIAL HAZARD
• When engine is running, cutting head is
rotating and other parts are moving.
WHAT CAN HAPPEN
• Contact with rotating cutting head or other
moving parts could cause serious personal
injury or death.
HOW TO AVOID THE HAZARD
• Always turn off your Trimmer before you clean
or perform any maintenance on it.
The Toro String Trimmer will provide maximum
performance for many, many hours if it is maintained
properly. Good maintenance includes regular checking of
all fasteners for correct tightness, and cleaning the entire
machine.
Storage
For long-term storage of the String Trimmer:
1. Empty the fuel tank into a suitable fuel storage
container.
2. Pump the primer bulb on the carburetor until all fuel is
discharged through the clear fuel return hose.
3. Run the engine to remove any fuel that may remain in
the carburetor.
4. Perform all regular maintenance procedures and any
needed repairs.
5. Remove the spark plug and squirt a very small amount
of oil into the cylinder (Fig. 29).
POTENTIAL HAZARD
• Oil may squirt out of the spark plug opening
when you pull the starter handle.
WHAT CAN HAPPEN
• Oil can cause eye injuries.
HOW TO AVOID THE HAZARD
• Protect your eyes and keep your face away
from the spark plug opening.
6. Pull the starter handle once.
