2. Transaxle
Check the level of fluid in both of the fluid
reservoirs. Wipe away all dirt and debris from
around reservoir cap before removing. Oil
must remain absolutely clean! Check with
machine on a level surface with engine

level up to 1-1/2 inches below the top of the
filler neck. Use clean, fresh premium
hydraulic oil having a viscosity equivalent to
SAE 20W20, SAE 30 or SAE40. The fluid
should be chemically stable, incorporating rust
and oxidation inhibitors. Make sure funnels,
pouring spouts and oil can are completely
clean. Reinstall reservoir cap. See Figure 3.6.
IMPORTANT: DO NOT remove or service
the transaxle fluid filters. This service should
be made periodically by an authorized
SNAPPER dealer. See the service schedule
to determine the recommended change
interval.
3. Power Transfer Shaft

Dirt can also be introduced
into an engine In dirty fuel
from a contaminated
container. Always use clean
fresh fuel from a clean
container to guard against
dirt, sludge and water
contamination.
Be aware that fuel breaks
down In storage and forms
will block carburetor pass-
ages. Never use fuel more
than 3 months old. Drain
tank then run the engine out
of fuel before storing during
the off-season.
An engine must also have proper lubrication.
All engines use some oil On 4-cycle engines,
CHECK OIL LEVEL BEFORE EACH START-UP.
Wipe area clean around the oll check plug or
dipstick opening to keep dirt from falling Into
the engine when checking the oil Always
check with the machine on a level surface.
On engines with dipstick, keep the level up to,
but not over, the FULL mark. When adding oil,
allow time for all of the oll to flow down the fill
tube to prevent afalse full reading when the
level could actually be low and result In engine
damage.
