Check Grease Level in Transmission
1. Remove the transmission fill plug (A, Figure 15).
Roll the machine forward or backward while look-
ing 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.

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 17). Do not tilt the
mower with the spark plug or carburetor down.
IMPORTANT: 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 should be 40 lb-ft (54 N.m).
4. Check the blade for sharpness, wear and damage.
Refer to the Section entitled “Blade Wear Limits”.
