OPERATION

KNOW YOUR CHIPPER-SHREDDER

READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR CHIPPER-SHREDDER,

Compare the illustrations with your chipper-shredder to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference.

MEETS ANSI SAFETY STANDARDS

Sears chipper-shredders conform to the safety standards of the American National Standards Institute,

OPERATING CONTROLS (See figure 6)

RELEASE BAR—Used to release the hopper when

raising or lowering .

CHOKE LEVER—Used to enrich the fuel mixture in

the carburetor when starting a cold engine.

BEFORE USING YOUR CHIPPER-SHREDDER, AGAIN REFER TO THE “SAFETY RULES” AS SHOWN ON PAGE 2 OF THIS MANUAL. ALWAYS BE CAREFUL.

The operation of any chipper-shredder can result in foreign objects being thrown into the eyes, which can result in severe eye damage. Always wear the safety glasses pro vided with the chipper-shredder or eye shields before chipping or shredding, or while performing any adjustments or repairs. We recommend Wide Vision Safety Mask for over spectacles or standard glasses available at Sears Retail or Catalog Stores.

stops the engine.

BEFORE STARTING

GAS AND OIL FILL-UP

NOTE: ENGINE IS SHIPPED WITHOUT OIL FILL

CRANKCASE WITH OIL BEFORE STARTING. BE VERY CAREFUL NOT TO ALLOW DIRT TO ENTER THE ENGINE WHEN CHECKING OR ADDING OIL OR FUEL

Recommended SAE Viscosity Grades

30or10W30 ^

C 5W30

-20° 0° 32° 60° 80° 100°

TEMPERATURE RANGE EXPECTED BEFORE NEXT OIL CHANGE. ALL OILS MUST BE A P I. SERVICE CLASSIFICATION SD, SE OR SF

® Fill engine with oil as follows. Remove oil fill dip

stick. See figure 7 With chipper-shredder level, use a funnel to fill engine with oil to FULL mark on dipstick. Capacity is approximately 1-1/4 pints Be careful not to overfill. Tilt chipper-shredder 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.

Caution: Experience indicates that alcohol 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 empty before storage for 30 days or longer. Refer to "Storage” section of this manual for details. Use fresh fuel each season, Never use engine or carburetor cleaner products in the fuel lank or permanent damage may result

NOTE: USE CLEAN OIL AND FUEL. STORE IN

APPROVED, CLEAN, COVERED CONTAINERS.

USE CLEAN FILL FUNNELS,

® Remove fuel cap and fill fuel tank, See figure 8,

Use fresh, clean, unleaded automotive gasoline. Capacity is 3 quarts. Replace fuel cap.

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 CHIP

PER-SHREDDER AWAY FROM AREA

OF SPILL. AVOID CREATING ANY SOURCE OF IGNITION UNTIL GASO

LINE VAPORS HAVE DISAPPEARED.

Check the fuel level periodically to avoid running out of gasoline while operating the chipper-shredder. If the unit runs out of gas as it is shredding or chipping, it may be necessary to unciog the unit before it can be restarted. Refer to "Removing the Flail Screen" on page 13.

TO START ENGINE

WARNING: BE SURE NO ONE OTHER THAN THE OPERATOR IS STANDING

® Attach spark plug wire and rubber boot to spark

plug if necessary See figure 8

® Place the throttle control lever in FAST position.

See figure 9,

® Move choke lever to CHOKE position, ® Grasp starter handle (see figure 9) and pull rope

out slowly until engine reaches start of compres sion 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 falling 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.

NEAR THE CHIPPER-SHREDDER WHILE STARTING OR OPERATING. DO

NOT OPERATE THIS CHIPPER-SHRED DER UNLESS THE CHUTE DEFLECTOR HAS BEEN PROPERLY INSTALLED

AND IS SECURED WITH THE HAND

KNOBS.
