WARNING:
Always shut off engine before fueling. Never add fuel to a
machine with a running or hot engine. Move at least 30 ft.

ADDING/CHECKING ENGINE LUBRICANT
See Figure 4.
NOTICE:
Attempting to start the engine before it has been properly
filled with lubricant will result in equipment failure.
Engine lubricant has a major influence on engine perfor-
mance and service life. This unit is shipped with a 20W50
engine lubricant to assist in the break-in period. For best
operating performance, continuing to use 20W50 engine
lubricant is recommended, however, SAE 30, 10W30, or
10W40 are all acceptable lubricants to use in this product.
Always use a 4-stroke engine lubricant that meets or exceeds
the requirements for API service classification SJ. Check
lubricant level before each use.
NOTE: Non-detergent or 2-stroke engine lubricants will
damage the engine and should not be used.
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:

Set unit on a flat surface.
 Wipe dipstick clean and re-seat in hole; do not 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 POWER HEAD
See Figure 5.
WARNING:
Engine housing can become hot during operation. Do not
rest or place your arm, hand, or any body part against
the engine housing during operation. Only hold the unit
as shown in Figure 5 during trimmer operation with all
body parts clear of engine housing (or as shown in the
applicable attachment Operator’s Manual). Extended
contact with the engine housing can 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 power head 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. Power head should be held at
a comfortable position with the rear handle about hip height.
Always operate power head at full throttle. If debris becomes
wrapped around the attachment, STOP THE ENGINE,
disconnect the spark plug wire, and remove the debris.
Prolonged cutting at partial throttle will result in lubricant
dripping from the muffler.
WARNING:
Always hold the power head away from the body keeping
clearance between the body and the product. Any
contact with the attachment cutting head can result in
burns and/or other serious personal injury.
WARNING:
Extreme care must be taken when using a blade attachment
to ensure safe operation. Read the safety information for safe
operation when using a blade attachment and refer to the
safety rules and instructions in your attachment manual.
Improper operation of a blade or any attachment could
result in serious injury.
