Engine Oil & Oil Filter
Refer to Figure 5-12:
See “Engine Specifications & Capacities” on page 51
and “Engine Operator’s Manual” for oil type, capacity
and maintenance schedule. Check oil daily and after ever
4 hours of operation. Mower must be sitting level when
checking oil. Change engine oil and oil filter after the first
54 hours of operation and per engine manufacture’s
recommendations thereafter. Change oil more frequently
if mower is operated in extremely dirty conditions.
Check Engine Oil
Refer to Figure 5-12:
1. Park on a level surface, shut engine off and allow
time for oil to cool and drain into the sump.
2. Clean area around oil fill cap/dipstick (#1) of dirt and
debris before removing it. Unscrew oil fill cap and
wipe dipstick clean.
3. Check oil level on dipstick by insert dipstick fully in
without screwing it in and removing again to check
oil level.
4. If oil level on the dipstick is near or below lower limit
mark on dipstick, add recommended oil until it
reaches the full mark. Do not overfill.
5. Reinstall oil filler cap/dipstick by screwing it in firmly.
IMPORTANT: Make certain engine is level and you
are inserting the dipstick correctly when checking
oil. Incorrect oil levels can cause engine problems.
Change Engine Oil
