Storage; Storing The Battery; Preparing The Machine For Seasonal Storage - Toro 03910 Operator's Manual

Storage

Storing the Battery

If the machine will be stored more than 30 days, remove
the battery and charge it fully. Store the battery in a cool
atmosphere to avoid quick deterioration of the charge in the
battery. To prevent the battery from freezing, make sure
that it is fully charged. The specific gravity of a fully charged
battery is 1.265–1.299.
Preparing the Machine for
Seasonal Storage
Follow these procedures anytime you will be storing the
machine for more than 30 days.
Preparing the Traction Unit
1. Thoroughly clean the traction unit, the cutting units,
and the engine.
2. Check the tire pressure. Inflate all tires to 83 kPa (12
psi).
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. Remove the battery.
C. Slowly recharge the battery before storage and
every 60 days thereafter for 24 hours to prevent
lead sulfation of the battery.
To prevent the battery from freezing, make sure
it is fully charged. The specific gravity of a fully
charged battery is 1.265–1.299.
D. Clean the battery, terminals, and posts with a wire
brush and baking soda solution.
E. Coat the cable terminals and battery posts with
Grafo 112X skin-over grease (Toro Part 505-47)
or petroleum jelly to prevent corrosion.
F. Either store it on the shelf or on the machine in
a cool area. Leave the cables disconnected if it is
stored on the machine.
Preparing the Engine
1. Drain the engine oil from the oil pan and replace the
drain plug.
2. Remove and discard the oil filter. Install a new oil filter.
3. Refill the oil pan with approximately 3.8 liters (4 US qt)
of SAE 15W-40 motor oil.
4. Start the engine and run it at idle speed for
approximately 2 minutes.
5. Stop the engine.
6. Thoroughly drain all fuel from the fuel tank, fuel lines,
fuel filter, and water separator assembly.
7. Flush the fuel tank with fresh, clean diesel fuel.
8. Secure all fuel system fittings.
9. Thoroughly clean and service the air-cleaner assembly.
10. Seal the air-cleaner inlet and the exhaust outlet with
weatherproof tape.
11. Check the anti-freeze protection and add
antifreeze/coolant as needed for the expected
minimum temperature in your area.
