MTD Shredder 642D thru 648D - Manual (Page 7)

1. Place the throttle control lever in FAST position.
See figure 5.
2. Engines with choke lever: Move choke lever to
CHOKE position (a warm engine may not require
choking).
Engines with primer: Prime engine as instructed
in separate engine manual.
3. Grasp starter handle (see figure 5) 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.
4. Pull rope with a rapid, continuous, full arm stroke.
Keep a firm grip on starter handle. Let rope
rewind slowly. Do not let starter handle snap back
against starter.
5. Repeat preceding instructions 3 and 4 until
engine fires. When engine starts, move choke
lever (if so equipped) on engine halfway between
CHOKE and RUN.
6. Move throttle control to IDLE position for a few
minutes warm-up. Move choke lever (If so
equipped) to RUN position as engine warms up.
NOTE: In order to idle smoothly, a new engine may
require 3 to 5 minutes running above siow idle speed.
Idle speed has been adjusted to be correct after this
break-in period.
TO STOP ENGINE
1. Move throttle control lever to STOP position.
2. Disconnect spark plug wire and move away from
spark plug to prevent accidental starting while
equipment is unattended.
3. Close fuel shut-off valve (if so equipped) when
unit is not in use to prevent fuel leakage.
HOW TO USE YOUR SHREDDER
Do not attempt to shred or chip any material other
than vegetation found in a normal yard (i.e., branches,
leaves, twigs, etc.).
A WARNING: The shredder discharges
material with considerable velocity. Keep
away from the area around the chute
deflector. Always stop the engine and dis­
connect the spark plug wire when remov­
ing or attaching the bag, when changing
containers or when removing the shred­
ded material, wear safety glasses and
gloves whenever using your shredder.
The shredder is designed for three different methods
of operation.
1. Leaves and small branches up to 1/2" diameter
can be fed into the hopper when it is in the raised
position. See figure 6. If it becomes necessary to
push material into the shredder, use a small
diameter stick—NOT YOUR HANDS. The stick
cannot exceed 1/2" in diameter so it will be
ground up if it gets into the impeller assembly.
A
WARNING: Do not put material larger than
1/2" in diameter into the hopper. Material
up to a maximum of 3" in diameter materi­
al may be fed into the chipper chute. Do
not attempt to shred or chip any material
larger than 3" in diameter. Personal injury
or damage to the machine could result.
No Larger Than
1/2" Diameter

2. Leaves and small twigs can be raked into the
shredder when the hopper assembly is lowered to
the ground. See figure 7.
To lower the hopper assembly to the ground, use
one hand to grasp the top of the hopper assem­
bly. Push down on the release handle, and pivot
the hopper assembly to the right. See figure 8.
