B: Special Control Bar Test
1. With the engine off, wheel mower onto a paved
surface in a non-windy area.
2. Put all four wheels in "3" height–of–cut position
(Fig. 13).
3. Put ground speed selector in "N" (neutral)
position.
4. Take a half sheet of newspaper and crumple it
into a ball small enough to go under the deck
(approx. three inches in diameter) (Fig. 14).
5. Place ball of newspaper five inches in front of
mower (Fig. 14).
6. Start the engine.
7. Push control bar down to lowest position
(Fig. 17, position B).
8. Bring the control bar up into the mid position
(about 5 inches below the handle cross bar)
(Fig. 18, position C).
Note: This intermediate position (C) is not
the "natural" operating position of the
control bar. However, it has proven to
be useful in early detection of BBC
sticking which could create an unsafe
condition later in the life of the mower.
9. Release control bar (Fig. 18, position B).
Note: If a loud bang is heard, the control bar
has been raised too high. Repeat steps
7, 8 and 9, but do not raise the control
bar as high as in step 8.
10. Immediately push the mower over the newspaper
ball.
11. Turn off the engine.
12. Walk around the mower to check for the
newspaper ball. If the ball did not go under the
deck, repeat steps 5–11.
EN–11
13. Pull mower away from newspaper. If the
newspaper ball unravels or is shredded, it
indicates the system could be experiencing
wear/deterioration which could result in an
unsafe operating condition. Use care in operating
the mower and BBC system and contact an
Authorized Toro Service Dealer for an inspection
of your mower at your earliest convenience.
They will ensure that appropriate corrective
measures are performed and your mower is
restored to proper operating condition.
POTENTIAL HAZARD
If the Blade Brake Clutch system is
inoperative, blade will continue to rotate
when control bar is released. Contact with
blade could occur.
WHAT CAN HAPPEN
Blade contact can cause serious personal
injury or death.
HOW TO AVOID THE HAZARD
Never use a BBC equipped power mower
with an inoperative safety system.
Return your lawn mower to your dealer for
repair if a safety system fails to operate
properly.
SPECIAL NOTE: Whenever performing operations
such as cleaning the mower, first stop the engine and
disconnect the spark plug wire. Remove key from
switch on electric start model. As with any lawn
mower, regardless of the safety features and blade
stopping devices used, operators should keep all body
parts away from the cutting blade area whenever the
mower's engine is running, and keep bystanders away
as well.
