ADDING/CHECKING ENGINE LUBRICANT
See Figure 4.
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 motor lubricant that meets or exceeds
the requirements for API service classification SJ. Check
lubricant level before each use.
NOTE: Non-detergent or 2-cycle engine lubricants will dam-
age the engine and should not be used.
To add engine lubricant:
NOTICE:
Attempting to start the engine before it has been properly
filled with lubricant will result in equipment failure.
 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.
OXyGENATED FUELS
NOTICE:
Do not use E15 or E85 fuel (or fuel containing greater
than 10% ethanol) in this product. It is a violation of
federal law and will damage the unit and void your
warranty.
Fuel system damage or performance problems resulting
from the use of an oxygenated fuel containing more than
the percentage of oxygenates stated below are not covered
under warranty.
Ethanol. Gasoline containing up to 10% ethanol by volume
(commonly referred to as E10) is acceptable. E15 and E85
are not.
OPERATION
FILLING THE TANK
WARNING:
Gasoline and its vapors are highly flammable and ex-
plosive. To prevent serious personal injury and property
damage, handle it with care. Keep away from ignition
sources and open flames, handle outdoors only, do not
smoke, and wipe up spills immediately.
 Clean the surface around the fuel cap to prevent con-
tamination.
 Loosen the fuel cap slowly by turning counterclock-
wise.
 Pour the fuel carefully into the tank.
 Clean and inspect the fuel cap gasket before replacing
the fuel cap.
 Replace the fuel cap and tighten it by turning it clock-
wise.
 Wipe spilled fuel from the product.
 Move at least 30 ft. away from refueling area before
starting the product.
NOTE: It is normal for smoke to be emitted from a new
engine during first use.
WARNING:
Always shut off engine before fueling. Never add fuel to a
machine with a running or hot engine. Move at least 30 ft.
from refueling site before starting engine. Do not smoke
and stay away from open flames and sparks. Failure to
safely handle fuel could result in serious personal injury.
STARTING AND STOPPING
See Figures 5 - 6.
Blower should be on a flat, bare surface for starting.
 Slowly press the primer bulb 10 times.
NOTE: After the 7th press, fuel should be visible in the
primer bulb. If it is not, continue to press the primer until
you see fuel in the bulb.
 Set the choke lever to the FULL CHOKE position.
 Do not squeeze the throttle trigger. Start the unit with the
cruise control lever in the IDLE position. Pull the starter
grip and rope sharply until engine attempts to run (no
more than 4 pulls).
 Set the choke lever to the HALF CHOKE position.
 Pull the starter grip and rope until the engine runs. Do not
pull the starter grip and rope more than six (6) times.
NOTE: If the engine does not start, return to the FULL
CHOKE position and repeat the steps that follow.
 Allow the engine to run for 15 seconds, then set the choke
lever to the RUN position.
