Operating Safety
Using The Chipper

When using the chipper, you can feed branches (up to 2" thick) into the
chipper chute for processing by the chipper blade.

Be sure that the collection bag is empty and in place before chipping.

Wear safety goggles, gloves, and hearing protection when chipping.

Start the engine on level ground. Leave the GEAR SHIFT LEVER in N
(Neutral).

To feed materials into the chipper tube, stand a foot or two away from either
side of the chipper chute. Do not stand near the hot engine exhaust or
muffler (Figure 23).
 Use common sense when using the chipper. Learn to recognize the change
in sound when the engine is overloading. Pull back on whatever you are
chipping if overloading should occur.

Green or dry branches chip easily and soft wood will chip easier than hard
wood. Branches are fed into the chipper chute for chipping. . . one at a time
if they are thicker then 1"; several smaller diameter twigs can go together.
Since the throat opening is 4 inches wide, some side shoots or side branches
may have to be trimmed from the main stalk before chipping. Short stubs of
branches may be pushed through the chipper section with the next branch.
NEVER ALLOW YOUR HANDS TO ENTER THE CHIPPER TUBE. If
necessary, push the material further down with a long stick or branch. Be
safe, keep your hands away from the chipping blade.
 When chipping branches occasionally a “tail” will be left at the end of the branch (usually green wood), which increases in
length as you chip and eventually wraps around the shaft. To avoid this, slowly turn the branch as you feed it into the chipper
tube. This will also improve the chipping performance.
 When chipping, frequently empty the bag because of the weight of the accumulative chips.
Using The Vacuum
 Before leaves drop, mow your lawn to the shortest recommended height. Your LLV will vacuum better on short grass.

A vacuum is designed to be used frequently during periods when leaves are dropping. Do not let leaves get 4” or more deep.
The drier the leaves the better.

The thicker the leaf layer the slower you should proceed. If leaves are wet or matted down use 1 st gear, it may be necessary to
fluff up leaves before using the vac. If snout clogs try a slower speed.

Snout height is critical. The snout should ride above the leaf layer to allow proper vacuuming… closer is not always better. The
snout flap should scrape the top of the grass.

You should avoid vacuuming twigs and branches into the snout. This will cause clogging. Process them through the chipper
tube.

The operation of any LEAF and LAWN 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 LEAF and LAWN VACUUM or eye shields before
chipping or while performing any adjustments or repairs.

Only operate your LEAF and LAWN VACUUM from the rear or from the chipper side. If it is necessary for any reason to
inspect or repair any part of the machine where a moving part can come in contact with your body or clothing, stop the
engine, allow it to cool, disconnect the spark plug wire from the spark plug and move it away from the spark plug before
attempting any inspection or repairs.
