Sears 247.79964 - Manual (Page 11)

Check the fuel level periodically to avoid running out
of gasoline while operating the chipper-vacuum. If the
unit runs out of gas as it is chipping, it may be neces­
sary to unclog the unit before it can be restarted.
Refer to “Removing the Flail Screen” in SERVICE
AND ADJUSTMENT section.
WARNING: EXPERIENCE INDICATES THAT ALCO­
HOL BLENDED FUELS (CALLED GASOHOL OR
USING ETHANOL OR METHANOL) CAN ATTRACT
MOISTURE WHICH LEADS TO SEPARATION AND
FORMATION
OF ACIDS DURING STORAGE.
ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM
OF AN ENGINE WHILE IN STORAGE. TO AVOID
ENGINE PROBLEMS, THE FUEL SYSTEM
SHOULD BE EMPTIED OR TREATED WITH FUEL
STABILIZER BEFORE STORAGE FOR 30 DAYS
OR LONGER. USE FRESH FUEL NEXT SEASON.
SEE
“STORAGE” SECTION FOR ADDITIONAL
INFORMATION.
NEVER USE ENGINE OR CARBURETOR CLEAN­
ER PRODUCTS IN THE FUEL TANK OR PERMA­
NENT DAMAGE MAY OCCUR.
TO START ENGINE
IMPORTANT: IF UNIT SHOWS ANY SIGN OF
MOTION WITH THE CLUTCH HANDLE DISEN­
GAGED,
SHUT ENGINE OFF IMMEDIATELY.
READJUST AS INSTRUCTED IN THE “FINAL
ADJUSTMENTS” SECTION OF THE ASSEMBLY
INSTRUCTIONS.
A
WARNING: BE SURE NO ONE OTHER
THAN THE OPERATOR IS STANDING
NEAR THE CHIPPER-VACUUM WHILE
STARTING OR OPERATING. DO NOT
OPERATE THIS CHIPPER-VACUUM
UNLESS THE NOZZLE, DISCHARGE
CHUTE AND BAG HAVE BEEN PROPER­
LY INSTALLED.
Attach spark plug wire and rubber boot to spark
plug if necessary. See figure 9.
Place the throttle control lever in FAST position.
Move choke lever to CHOKE position (See figure
14).
Place one foot on the left rear wheel to prevent the
unit from skidding while starting.
Grasp starter handle and pull rope out slowly until
engine reaches start of compression cycle (rope
will pull slightly harder at this point). Let the rope
rewind slowly.
NOTE: A noise will be heard when finding the start of
the compression cycle. This noise is caused by the
flails and fingers which are part of the shredding mech­
anism failing into place, and should be expected. In
addition, the flails and fingers will be noisy after the
engine is started, until the impeller reaches full speed.
• Pull rope with a rapid, continuous, full arm stroke.
Keep a firm grip on start handle. Let rope rewind
slowly. Do not let starter handle snap back against
starter.
• Repeat preceding two instructions until engine
fires. When engine starts, move choke lever on
engine haifway between CHOKE and OFF.
NOTE: if engine does not fire after three attempts,
move choke lever halfway between CHOKE and OFF
position and try again.
® Move throttle control to IDLE position for a few min­
utes warm-up. Move choke lever to OFF position
as engine warms up.
NOTE: In order to idle smoothly, a new engine may
require 3 to 5 minutes running above slow idle speed.
Idle speed has been adjusted to be correct after this
break-in period.
