MTD Yard-Man 203b - Manual (Page 5)

BEFORE USING YOUR CHiPPER-SHREDDER-VACUUM, REFER TO THE “SAFETY RULES” ON PAGES 2 AND
3 OF THIS MANUAL. ALWAYS BE CAREFUL
The operation of any chipper-shredder-vacuum can result in foreign objects being thrown into the eyes, which
can damage your eyes severely. Always wear the safety glasses provided with this unit or eye shields
before chipping, or while performing any adjustments or repairs. We recommend Wide Vision Safety Mask
for over spectacles or standard glasses.
OPERATION
IMPORTANT: Care should be taken not to shut off
the engine or to run out of gasoline while operat­
ing the chipper-shredder-vacuum. Check the fuel
level periodically to avoid running out of gasoline.
Do not turn the engine off until all chipping is com­
pleted to avoid jamming. If the unit runs out of gas
or is turned off while it is chipping or shredding it
may be necessary to unclog the unit before it can
be restarted. Refer to “Removing the flail screen”
in the Maintenance section.
CONTROLS
ORIVE CLUTCH CONTROL (Model 203B only)
Squeezing the drive clutch control engages the drive
mechanism to the rear wheels. Releasing the clutch
control stops the rear wheels from driving. Release the
drive clutch control to slow down when negotiating an
obstacle, making a turn or stopping. See figure 4.

iMPORTANT: If unit shows any sign of motion with the
drive clutch control disengaged, shut engine off imme­
diately. Readjust as instructed in the “Drive Clutch
Cable Adjustment” in the Adjustment Instructions.
A WARNING: Be sure no one other than the
operator is standing near the chipper-
shredder-vacuum whiie starting or operat­
ing. Do not operate this chipper-shredder-
vacuum

2. Make certain drive clutch control is in the disen­
gaged (released) position.
Engines with choke lever:
3. Move choke lever on engine to CHOKE position.
(A warm engine may not require choking.)
Engines with primer:
4. Prime engine as instructed in separate engine
manual.
5. Move throttle control lever on engine to FAST
position.
6. Place one foot on the left rear wheel to prevent the
unit from skidding while starting.
7. Grasp starter handle and pull rope out slowly until
engine reaches start of compression cycle (rope
will pull slightly harder at this point). Let the rope
rewind slowly.
NOTE: You may hear a noise when reaching the start
of the compression cycle. This noise is caused by the
flails and fingers, which are part of the shredding
mechanism, 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.
8. 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.

When engine starts, move choke control (if so
equipped) gradually to RUN position.
