6. Check the fuel level.
7. Check the engine oil level. Running the engine without enough oil can
damage the engine.
8. Look around and underneath the engine for signs of oil or gasoline leaks.
a. Do not start the engine until any spilled fuel has evaporated.
9. Remove any excessive dirt or debris, especially around the muffler and
recoil starter (F).
10. Look for signs of damage.
11. Check the equipment powered by this engine.
AIR FILTER
Dismantle the air filter cover and check its element to make sure it is clean and
in good operation. Clean or replace as necessary.
CAUTION! Never run the engine without an air filter or severe engine wear
may result.
FUEL RECOMMENDATION
1. Remove the fuel tank cap and check the fuel level.
2. If the level is too low, refuel the tank (see Care & Maintenance – How to
Add Fuel)
HEAD RANGE FOR PUMP
Head is defined as the amount of water the pump will discharge through the
hose at a vertical height. The amount of water (flow) decreases as the discharge
height is increased. The length, type and size of the suction and discharge
hoses can also significantly affect pump output.
Suction head or Suction Lift is the vertical distance between the center of the
pump and the end of the suction hose. The maximum lift is 26 feet due to water
pressure (a jet pump is required for additional depth).
The dynamic head is a combination of the Head and Suction Head when the
pump is set up. The maximum height difference cannot exceed 82 feet. If the
suction lift is 12 feet, the maximum head is 70 feet.
The suction lift hose should be as short as possible to increase pump efficiency and
reduce priming time. The suction set up should not exceed the discharge set up.
