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.
WARNING
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. Engine and components are
HOT. Avoid serious burns, allow sufficient time for
all components to cool. Wear heavy leather gloves
when handling or working around cutting blades.

injury.
3.2 SERVICE - AFTER FIRST 5 HOURS
3.2.1. CHANGE ENGINE OIL
IMPORTANT: Drain fuel tank before tipping machine.
DO NOT tip machine with carburetor or spark plug down.
Oil from 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.
1. Refer to Engine Manual for proper oil
specifications, procedures and proper service
intervals.
For simplest/cleanest oil change, simply turn mower on its
side to drain oil, as shown in Figure 3.1. Drain oil through
dipstick tube into a container. Allow sufficient time for all oil
to drain.
