Section 3 - MAINTENANCE
3.1 INTRODUCTION
To retain the quality of the mower, use genuine
SNAPPER replacement parts only. Contact a local
SNAPPER dealer for parts and service assistance.
For the correct part or information for a particular
mower, always mention model and serial number.
3.2 SERVICE - AFTER FIRST 5 HOURS
3.2.1. CHANGE ENGINE OIL
WARNING
Before attempting any adjustments or repairs, STOP
the engine, remove the spark plug wire from the
spark plug and secure wire away from plug. Wear
heavy leather gloves when handling or working
around cutting blades. Blades are extremely sharp
and can cause severe injury. Engine oil is extremely
hot and can cause severe burns. Allow engine oil to
cool before draining to prevent injury.
1. Disconnect spark plug wire and secure end away
from plug. The items needed to perform oil change
are: cloth rags, (1) 3/8” drive ratchet with a short
extension and (1) shallow pan.
2. Tilt mower up on its rear wheels for access to
the oil drain plug located underneath the mower
deck. Do not tilt mower with spark plug or
carburetor down. See Figure 3.1.
FIGURE 3.1
3. Place shallow pan underneath the approximate
center of the oil drain plug.
4. Loosen with ratchet and short extension, but do
not remove oil drain plug. Loosen plug until you can
turn it with your fingers.
5. Lower the mower down and place the piece of
wood under left rear wheel. Reach under mower
and remove drain plug and allow oil to drain out
completely in pan. Some oil may spill onto hands,
immediately wipe hands clean with cloth rags.
6. Tilt mower back up and replace drain plug.
Tighten securely but do not over tighten.
7. Fill engine with oil as specified in Engine
Owner’s Manual. Thereafter, change oil after each
25 hours of use.
IMPORTANT: DO NOT tip machine with carburetor or
spark plug down, oil from crank case will saturate the air
filter and cause the engine to hard start or not start at all.
If contamination does occur the air filter will have to be
replaced.

from plug.
