Check Engine Oil
1.
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.
2.
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 manufac-
turer'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.
To Drain Oil
WARNING
Used oil is a hazardous waste product. Dispose of used oil properly
Do not discard with household waste. Check with your local authori-
ties or Sears Service Center for safe disposal/recycling facilities.
WARNING
Before tipping engine or equipment to drain oil, drain fuel from tank by
running engine until fuel tank is empty.
WARNING
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.
SERVICE AND MAINTENANCE
Figure 24
1.
Drain the fuel from the tank by running the engine until the fuel
tank is empty. Be sure fuel fill cap is secure.
2.
With engine OFF but still warm, disconnect spark plug wire and
keep it away from spark plug.
3.
Remove oil drain end cap located at the base of the engine, and
drain oil into an appropriate receptacle. See Figure 25.
4.
Replace and tighten the oil drain end cap.
5.
When engine is drained of all oil, place engine level. Refill with
approximately 20 oz. of fresh oil. Fill to FULL line on dipstick.
Do not overfill. Refer to Check Engine Oil in this SERVICE &
MAINTENANCE section.
6.
Replace spark plug wire before starting.
LUBRICATION
After every 10 operating hours, oil or grease the lubrication points. Use
clean lubricating oil (#30 weight motor oil is suitable) and clean general
purpose grease (grease containing a metal lubricant is preferred, if
available).
•
Remove the tines and clean the tine shaft. Use a file or sandpa-
per to gently remove any rust, burrs or rough spots (especially
around the holes in the shaft). Apply grease to the ends of the
shaft before installing the tines.
•
Remove the belt cover and lubricate all the pivot points and
linkages with a light coat of oil. Keep the belts free of lubrication.
•
The chain case is pre-lubricated and sealed at the factory and
requires no maintenance.
HARDWARE
Check for loose or missing hardware after every 10 operating hours
and tighten or replace — as needed — before reusing the tiller. Be
sure to check the screws underneath the tiller hood that secure the
transmission cover and the Depth Regulator Lever to the transmission.
