6.4.1 — Clean Debris
Daily or before use, clean accumulated debris from water
pump. Keep linkage, spring and controls clean. Keep
area around and behind muffler free from any combusti-
ble debris. Inspect cooling air slots and openings on the
water pump. These openings must be kept clean and
unobstructed.
Water pump parts should be kept clean to reduce the risk
of overheating and ignition of accumulated debris.
• Use a damp cloth to wipe exterior surfaces clean.
NOTE: Improper treatment of water pump can dam-
age it and shorten its life.
• DO NOT insert any objects through cooling slots.
• Use a soft bristle brush to loosen caked on dirt, oil, etc.
• Use a vacuum cleaner to pick up loose dirt and debris.

We recommend the use of high-quality detergent oils
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.
5W-30 5W-30
* Below 50 °F (10 °C) the use of SAE 30 will result in hard
starting.
** Above 80 °F (27 °C) the use of 10W30 may cause increased
oil consumption. Check oil level more frequently.
NOTE: The ST20K engine is equipped with an "Oil
Alert System". This system will automatically stop
the engine before the oil level falls below a safe limit.
To avoid the inconvenience of an unexpected shut-
down, always check the engine oil level before
startup.
6.8.1 — Check 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 flat, level surface.
2. Clean area around oil fill and wipe dipstick clean
remove oil fill cap (Figure 6-1).
3. Verify oil is at the proper level on the dipstick.
4. Replace and tighten oil fill cap.
