Operating The Trimmer; Starting And Stopping; To Check Engine Lubricant Level - Ryobi RY34425, RY34445 Operator's Manual

ADDING/CHECKING ENGINE LUBRICANT
See Figure 7.
Engine lubricant has a major influence on engine perfor-
mance and service life. This unit is shipped with Ryobi
4-cycle 20W50 engine lubricant. For best operating perfor-
mance, continued use of this lubricant is recommended.
NOTE: Always use a 4-stroke engine lubricant that meets
or exceeds the requirements for API service classification
SJ. SAE 30, 10W30, or 10W40 are all acceptable lubricants
to use in this product. Non-detergent or 2-stroke engine
lubricants will damage the engine and should not be used.
Check lubricant level before each use.
To add engine lubricant:
 Remove the cap and seal from lubricant bottle provided.
 Unscrew the oil cap/dipstick and remove.
 Using funnel provided, add entire bottle of engine lubricant
through oil fill hole.
 Reinstall the oil cap/dipstick and secure.

To check engine lubricant level:

 Separate the attachment from the power head.
 Set power head on a flat level surface with shaft parallel
to surface.
 Unscrew the oil cap/dipstick and remove.
 Wipe dipstick clean; re-seat in hole and rethread.
 Remove dipstick again and check lubricant level. Lubricant
level should fall within the hatched area on the dipstick.
 If level is low, add engine lubricant until the fluid level rises
to the upper portion of the hatched area on the dipstick.
 Replace and secure the oil cap/dipstick.
NOTICE:
Do not overfill. Overfilling the crankcase may cause
excessive smoke, oil loss, and engine damage.

OPERATING THE TRIMMER

See Figure 11.
WARNING:
Engine housing may become hot during trimmer opera-
tion. Do not rest or place your arm, hand, or any body
part against the engine housing during trimmer operation.
Only hold the trimmer as shown in figure 11 with all body
parts clear of engine housing. Extended contact with the
engine housing could result in burns or other injuries.
WARNING:
Always position the unit on the operator's right side. The
use of the unit on the operator's left side will expose the
user to hot surfaces and can result in possible burn injury.
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the trimmer with your right hand on the rear handle
and your left hand on the front handle. Keep a firm grip with
both hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Cut tall grass from the top down. This will prevent grass from
wrapping around the shaft housing and string head which
could cause damage from overheating. If grass becomes
wrapped around the string head, STOP THE ENGINE, dis-
connect the spark plug wire, and remove the grass.
