Oil And Fuel Information - Ryobi 990r Operator's Manual

THIS ENGINE IS CERTIFIED TO OPERATE ON UNLEADED GAS ONLY.
NOTE: BE SURE TO READ THESE
INSTRUCTIONS CAREFULLY BEFORE
ATTEMPTING TO START OR OPERATE
THIS UNIT. Using old or improper oil or
fuel can cause engine damage. This type
of damage will void the engine warranty.
RECOMMENDED OIL TYPE
Using the proper type and weight of oil in the crankcase is
extremely important. Check the oil before each use and
change the oil regularly. Failure to use the correct oil, or
using dirty oil, can cause premature engine wear and fail-
ure.
Use high-quality SAE 30 weight oil of API (American
Petroleum Institute) service class SG, SF.

Your unit is supplied with one bottle of oil, which contains
100 ml (3.4 fluid oz) of SAE 30 SF, SG oil (Fig. 14).

CHECKING THE OIL
The importance of checking and maintaining the proper oil
level in the crankcase cannot be overemphasized. Check
the oil BEFORE EACH USE as follows:
1. Make sure the engine is stopped, level (Fig. 16) and is
cool so the oil has had time to drain into the
crankcase.
2. To keep dirt, grass clippings, etc. out of the engine,
clean the area around the oil fill plug / dipstick before
removing it.
3. Remove the oil fill plug / dipstick; wipe the oil off.
Reinsert it into the crankcase. Thread the oil fill plug /
dipstick into the crankcase.
4. Remove the oil fill plug / dipstick and check the oil
level. The oil level should be up to the top of the dip-
stick (Fig. 17).
5. If the level is low, add the oil to the top of the dipstick
(Fig. 17). Always check the level with the dipstick
before adding more oil.
