Sears 247.79964 - Manual (Page 9)

MEETS ANSI SAFETY STANDARDS
Sears chipper-vacuums conform to the safety standards of the American National Standards Institute.
OPERATING CONTROLS (See figure 9)
SHIFT LEVER —The shift lever determines ground
speed. It may be placed in one of eight positions.
Forward —one of six speeds. Position number one (1)
is the slowest. Position number six (6) is the fastest.
Reverse —two reverse (R) speeds. “R” (all the way to
the right) is the faster of the two.
DRIVE CLUTCH HANDLE (BAIL)— Squeezing the
drive clutch handle against the upper handle engages
the wheel drive. Release the drive clutch handle to
stop the forward drive.
CHOKE LEVER —Used to enrich the fuel mixture in
the carburetor when starting a cold engine.
STARTER HANDLE —Used to manually start the
engine.
THROTTLE CONTROL —Controls engine speed and
stops the engine.
BEFORE USING YOUR CHIPPER-VACUUM, AGAIN REFER TO THE “SAFETY RULES” AS SHOWN ON
PAGE 2 OF THIS MANUAL. ALWAYS BE CAREFUL
The operation of any chipper-vacuum can result in foreign objects being thrown into the eyes, which
can result in severe eye damage. Always wear the safety glasses provided with the chipper-vacuum or
eye shields before chipping, 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.
TO STOP ENGINE
• Move throttle control lever to STOP position. See
figure 9.
• Disconnect spark plug wire and move away from
spark plug to prevent accidental starting while
equipment is unattended.
HOW TO USE YOUR CHIPPER-VACUUM
A WARNING: YOUR CHIPPER-VACUUM IS
EQUIPPED WITH A SAFETY SWITCH ON
THE FRONT OF THE HOUSING. NOZZLE
OR HOSE ATTACHMENT MUST BE IN
PLACE
ON THE CHIPPER-VACUUM
BEFORE THE ENGINE CAN BE STARTED.
TO ENGAGE DRIVE
IMPORTANT: Always release the drive clutch
handle before moving the shift lever.
• With the engine running near top speed, move shift
lever into one of the six FORWARD positions or
two REVERSE positions. Select a speed appropri­
ate for the conditions that exist. Use the slower
speeds until you are familiar with the operation of
the chipper-vacuum.
• To engage the wheel drive, hold the drive clutch
handle against the chipper-vacuum handle.
Releasing the drive clutch handle stops the wheels
from driving. Release the drive clutch handle to
slow down when negotiating an obstacle, making a
turn or stopping. Engage slowly to prevent front
wheels from lifting up.
NOZZLE HEIGHT ADJUSTMENT
The height adjustment knob is located on the right
hand side of the chipper-vacuum. See figure 10. Turn
the knob clockwise to raise the nozzle. Turn the knob
counterclockwise to lower. (Be careful not to turn
knob too far—rod could come out of ferrule.)
The best height for the nozzle will vary according to
the conditions. Adjust the height of the nozzle to find
the setting which gives the best performance for the
operating conditions. In general, raise the nozzle to
vacuum a thick layer of leaves: lower the nozzle for
smooth surfaces.
