Craftsman 247.799640 - Manual (Page 10)

if necessary, use the tamper plug provided to push
material into the chipper chute. See figure 8. NEVER
PLACE HANDS INSIDE CHIPPER CHUTE. Place
tamper plug inside chipper chute when not in use to
deaden the sound.
FIGURE 11.
IMPORTANT: There is a flail screen located inside
the housing in the discharge area, tf the fiail screen
becomes clogged, remove and clean as instructed in
the Service and Adjustment section on page 14.
For best performance, it is important to keep the
chipper blades sharp. If the composition of the
material being discharged changes (becomes stringy,
etc.) or if the rate at which the material is discharged
slows down considerably, it is likely that the chipper
blades are dull and need to be sharpened or
replaced. Refer to Service and Adjustments sections.
TO EMPTY BAG
Open the large zipper on the bag to empty the bag.
See figure 12. Be certain the zipper is closed when
operating the unit.
GAS AND OIL FILL-UP
OIL
Only use high quality detergent oil rated with API
service classification SF, SG or SH. Select the oil’s
viscosity grade according to your expected operating
temperature.
Colder 32°F Warmer
5W30 SAE 30
NOTE: Although multi-viscosity oils (5W30, 10W30,
etc.) improve starting in cold weather, these multi­
viscosity oils will result in increased oil consumption
when used above 32“F. Check your oil level more
frequently to avoid possible engine damage from
running low on oil.
• Use engine oil provided. Remove oil fill dipstick.
See figure 13. With chipper-vacuum level, use a
funnel to fill engine with oil to FULL mark on dipstick.
Capacity is approximately 26 ounces. Be careful not
to overfill. Oil bottle provided contains 27 oz. of oil.
Tilt chipper-vacuum toward the left (from behind the
hopper), then re-level. Check oil level. Refill to FULL
mark on dipstick if necessary. Replace dipstick and
tighten.
FIGURE 12.
GAS
• Remove fuel cap and fill fuel tank with approxi­
mately 1 gallon of clean, fresh, lead-free grade
automotive gasoline. DO NOT use Ethyl or high
octane gasoline. Be certain container is clean and
free from rust or foreign particles. Never use gaso­
line that may be stale from long periods of storage
in the container. Replace fuel cap.
A WARNING: DO NOT FILL CLOSER THAN
1/2 INCH OF TOP OF FUEL TANK TO
PREVENT SPILLS AND TO ALLOW FOR
FUEL EXPANSION. IF GASOLINE IS
ACCIDENTLY SPILLED, MOVE CHIPPER-
VACUUM AWAY FROM AREA OF SPILL.
AVOID CREATING ANY SOURCE OF
IGNITION UNTIL GASOLINE VAPORS
HAVE DISAPPEARED.
