Cleaning

Servicing the Spark Arrester
Muffler
Service Interval: Every 200 hours
Every 200 hours operation, clear the muffler of carbon
buildup.
1. Remove the pipe plug from the cleanout port at the
lower side of the muffler.
CAUTION
The muffler may be hot and could cause
injury.
Be careful while working around the muffler.
2. Start the engine. Plug the normal muffler exit with a
block of wood or metal plate so that the exhaust flow
will be forced out of the cleanout port.
Note: Continue to block the exit until carbon deposits
cease coming out of the port.
CAUTION
Do not stand in line with the cleanout port.
Always wear safety glasses.
3. Stop the engine and replace the pipe plug.

Storage

Preparing the Traction Unit

1. Thoroughly clean the traction unit, the cutting units,
and the engine.
2. Check the tire pressure; refer to Checking the Tire
Pressure.
3. Check all fasteners for looseness; tighten as necessary.
4. Grease or oil all grease fittings and pivot points. Wipe
up any excess lubricant.
5. Lightly sand and use touch-up paint on painted areas
that are scratched, chipped, or rusted. Repair any dents
in the metal body.
6. Service the battery and cables as follows:
A. Remove the battery terminals from the battery
posts.
B. Clean the battery, terminals, and posts with a wire
brush and baking soda solution.
C. Coat the cable terminals and battery posts with
Grafo 112X skin-over grease (Toro part 505-47)
or petroleum jelly to prevent corrosion.
D. Slowly charge the battery every 60 days for 24
hours to prevent lead sulfation of the battery.

only).

Preparing the Engine

1. Drain the engine oil from the oil pan and install the
drain plug.
2. Remove and discard the oil filter. Install a new oil filter.

9. Seal the air-cleaner inlet and the exhaust outlet with
weatherproof tape.
10. Check the antifreeze protection and add a 50/50
solution of water and ethylene glycol antifreeze as
needed for the expected minimum temperature in your
area.

Cutting Deck

If the cutting deck is separated from the traction unit for any
length of time, install a spindle plug in the top of the spindle
to protect the spindle from dust and water.
