Check the Engine Oil
Service Interval: Before each use or daily
Every 400 hours/Yearly (whichever
comes first)
The engine is shipped with oil in the crankcase; however,
the level of oil must be checked before you first start the
engine and after you have run it.
1. Position the machine on a level surface.

2. Remove the dipstick and wipe it with a clean rag
(Figure 50). Insert the dipstick into the tube and
make sure it is seated fully. Remove the dipstick and
check the oil level.

3. If the oil level is low, remove the filler cap from
the valve cover (Figure 50) and pour oil into the
opening until the oil level is up to the Full mark on
the dipstick. Add the oil slowly and check the level
often during this process. Do not overfill.
4. Install the dipstick firmly in place.
Changing the Engine Oil
Service Interval: After the first 50 hours—Change the
engine oil.
Every 100 hours—Change the engine
oil, including synthetic oil (more
often when operating under heavy
load or in high temperature).
1. Start the engine and let it run for five minutes. This
warms the oil so it drains better.
2. Set the parking brake, stop the pump, stop the
engine, and remove the ignition key.
3. Release the latch on the back of the seat and lift the
seat forward.
Components under the seat will be hot if the
sprayer has been running. If you touch hot
components you may be burned.
Allow the sprayer to cool before performing
maintenance or touching components under
the hood.
4. Place a pan below the oil drain.
5. Remove the drain plug (Figure 51).
