Oil
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF,
SG, SH, SJ or higher. DO NOT use special additives.
Outdoor temperatures determine the proper oil
viscosity for the engine. Use the chart to select the best
viscosity for the outdoor temperature range expected.
* Below 4° C (40° F) the use of SAE 30 will result in hard
starting.
** Above 27° C (80° F) the use of 10W30 may cause
increased oil consumption. Check oil level more frequently.
Figure
Checking Oil Level
Oil level should be checked prior to each use or
at least every 8 hours of operation. Keep oil level
maintained.
1. Make sure water pump is on a level surface.
2. Clean area around oil fill, remove oil cap/dipstick
and wipe dipstick with clean cloth. Replace dipstick.
Remove and check oil level.
3. Verify oil is at FULL mark (A) on dipstick.
4. Replace and tighten oil fill cap/dipstick.

Changing Engine Oil
If you are using your water pump under extremely
dirty or dusty conditions, or in extremely hot weather,
change the oil more often.
CAUTION Avoid prolonged or repeated skin contact
with used motor oil.
• Used motor oil has been shown to cause skin cancer in
certain laboratory animals.
• Thoroughly wash exposed areas with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.
Change the oil while the engine is still warm from
running, as follows:
1. Make sure water pump is on a level surface.
2. Disconnect the spark plug wire from the spark plug and
place the wire where it cannot contact spark plug.
3. Clean area around oil drain plug . The oil drain plug is
located at base of engine, opposite carburetor.
4. Remove oil drain plug and drain oil completely into a
suitable container.
5. Reinstall oil drain plug and tighten securely. Remove oil
cap/dipstick.
6. Slowly pour oil (about 0.6 l (20 oz)) into oil fill opening.
Pause to permit oil to settle. Fill to FULL mark (A) on
dipstick.
7. Reinstall oil cap/dipstick. Tighten cap securely.
8. Wipe up any spilled oil.
9. Reconnect spark plug wire to spark plug.

Service Air Cleaner
Clean or replace the air cleaner elements as
recommended in the Maintenance Chart or more
often if operating under dirty or dusty conditions. Your
engine will not run properly and may be damaged if
you run it with a dirty air cleaner.
To service the air cleaner, follow these steps:
1. Remove the fastener (A) and the cover (B).
2. Remove the fastener (C) and the filter (D).
3. Remove the pre-cleaner (E), if equipped, from the filter.
To loosen debris, gently tap the filter on a hard surface.
If the filter is excessively dirty, replace with a new filter.
4. Wash the pre-cleaner in liquid detergent and water. Then
allow it to thoroughly air dry. Do not oil the pre-cleaner.
5. Assemble the dry pre-cleaner to the filter.
6. Install the filter and pre-cleaner into the base(F) and
onto stud(G). Make sure filter fits securely into the base.
Secure the filter with the fastener(C).
7. Install the cover and secure with the fastener(A).Make
sure the fastener is tight.
Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other damage.
Remove the spark arrester, if equipped, and inspect
