STEP 1:
Check engine oil level. Oil level should be level with the bottom
of the oil fi ller neck. Be sure the machine is level when checking the oil
level. (Refer to the engine's operating manual included with machine.)
We recommend that the oil be changed after the fi rst 5 hours of use, then
once every 50 hours.
Note:
Improper oil levels will cause low oil sensor
to shut off engine.
IMPORTANT! Do not run engine with high or low
oil levels as this will cause engine damage.
STEP 2:
Remove shipping cap and
install oil dipstick. Check pump oil
level by using dipstick or observe
oil level in oil window (if equipped).
Use 40 wt. non detergent oil.
STEP 4:
Connect garden hose
to the cold water source and turn
water on completely. Never use
hot water.
STEP 6:

When the engine is not in use, leave the fuel valve in
the "OFF" position.
STEP 5:
Trigger the spray gun to
eliminate trapped air then wait for
