2. Drain the fuel tank and let the engine run until all fuel is
out of the carburetor.
Note: If using a fuel stabilizer, there is no need to drain the
fuel tank. See Storage - Fuel System.
3. Use a brush or compressed air to remove loose debris,
then use a damp cloth to wipe down the unit.
4. Tilt the mower up on its rear wheels and inspect the
underside of the deck. (Do not tilt the mower with the
spark plug or carburetor down.) Scrape away stubborn
accumulation of grass with a putty knife and/or wire
brush.
5. Lubricate all exposed metal with a light coating of oil to
prevent corrosion.
6. Carefully fold the handles, flexing the control cables to
prevent cable damage.
7. Store the mower in a shed or other dry area, protected
from weather.
NOTICE Do not stand unit on end.
Storage - Fuel System
Fuel can become stale when kept in a storage container
for more than 30 days. Each time you fill the container
with fuel, add fuel stabilizer to the fuel as specified by the
manufacturer's instructions. This keeps fuel fresh and
decreases fuel-related problems or contamination in the fuel
system.
It is not necessary to drain fuel from the engine when fuel
stabilizer is added as instructed. Before storage, turn the
engine ON for 2 minutes to move the fuel and stabilizer
through the fuel system.
Service
WARNING
Amputation Hazard
• DO NOT attempt any maintenance, adjustments or
service with engine and blade running.
• STOP engine and blade.
• Disconnect spark plug wire and secure away from spark
plug.
Burn Hazard
• Engine and components are HOT.
• Avoid serious burns, allow sufficient time for all
components to cool.
Laceration Hazard
• Wear heavy leather gloves when handling or working
around cutting blades.
• Blades are extremely sharp and can cause severe
injury.
Check Grease Level in Transmission
1. Remove the transmission fill plug (A, Figure 16). Roll the
machine forward or backward while looking down into the
plug hole.
2. If liquid grease is not visible on the input gear (the small
gear below the plug hole), add an amount, to cover the
gear, of Snapper "00" grease.
Note: Snapper "00" grease (Part No. 7029443) is available at
your dealer.
Note: Do not spill grease or oil onto the surface of the drive
disc (A, Figure 17).
3. Reinstall the transmission plug.
4. Check the grease level after each 25 hours of operation.
Check Mower Blade
1. Disconnect the spark plug wire and secure the end away
from the plug.
2. Tilt the mower up on its rear wheels for access to the
blade cap screw (A, Figure 18). Do not tilt the mower with
the spark plug or carburetor down.
NOTICE
Drain the fuel tank before tipping the mower. DO NOT tip
the machine with the carburetor or spark plug down. Oil
from the crankcase will saturate the air filter and cause the
engine to be hard to start or not start at all. If contamination
does occur, the air filter will have to be replaced.
3. Check the torque of the blade cap screw. Recommended
torque: 40 lb-ft (54 Nm).
4. Check the blade for sharpness, wear and damage. See
Blade Wear Limits .
Check Engine Drive Belt
• Visually check the engine drive belt for cracking, fraying,
severed or exposed belt strands. If worn or damaged,
replace the belt before operating the mower.
Check Transmission Drive Belt
• Visually check the poly-v belt for cracking, fraying,
severed or exposed belt strands. If worn or damaged,
replace the belt before operating the mower.
