Check Engine Oil

Check oil before each use. Stop engine and wait several minutes before

checking oil level. With engine on level ground, the oil must be to FULL mark

on dipstick.

Refer to the Assembly section of this manual for instructions on checking the

oil.

Change Engine Oil

•

Refer to the viscosity chart (Figure 24) for oil recommendations. Do not over-

fill. Use a 4-stroke, or an equivalent high detergent, premium quality motor

oil certified to meet or exceed U.S. automobile manufacturer's requirements

for service classification of a minimum level SF or SG (higher letter ratings

are acceptable such as SJ, SL and SM grades). Motor oil will display this

designation on the container.

NOTE: Do not use non-detergent oil or 2-stroke engine oil. It could shorten

the engine's service life.

•

Change engine oil after the first five to eight hours of operation, and every

fifty hours or every season thereafter. Change oil every twenty five hours

when operating engine under heavy load or in high temperatures.

Draining the Oil

Before tipping engine or equipment to drain oil, drain fuel from tank by

running engine until fuel tank is empty.

Used motor oil may cause skin cancer if repeatedly left in contact with the

skin for prolonged periods. Although this is unlikely unless you handle

used oil on a daily basis, it is still advisable to thoroughly wash your hands

with soap and water as soon as possible after handling used oil.

Drain the fuel from the tank by running the engine until the fuel tank is

empty. Be sure fuel fill cap is secure.

With engine OFF but still warm, disconnect spark plug wire and keep it away

from spark plug.
