Engine Maintenance
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. Engines on
most outdoor power equipment operate well with 5W30
Synthetic oil. For equipment operated in hot temperatures,
Vanguard ® 15W50 Synthetic oil provides the best
protection.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°F) the use of 10W30 may cause increased oil
consumption. Check oil level more frequently.
Add Engine Oil
1. Place pressure washer on level surface.
2. Clean area around oil fill and remove yellow oil fill cap/
dipstick.
3. Slowly pour oil into oil fill opening. Checking oil level
frequently, fill to full mark (top hole) on dipstick.
NOTICE Pause to permit oil to settle. Wipe dipstick clean
each time oil level is checked. Do not overfill.
4. Replace and tighten dipstick.
5. Wipe up any remaining oil.
NOTICE Do not attempt to start engine before it has been
properly serviced with oil. This could result in engine failure.
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. DO NOT
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.
