Fuel Shut-Off Valve
Product Overview
The fuel shut-off valve is the lower lever located on the
rear left hand side of the engine below the choke. The fuel
shut-off valve shuts off the flow of fuel when the machine will
not be used for a few days, when parking inside a building,
and during transport to and from the job.
Move the lever to the left to shut off fuel. Move the lever
to the right to turn on fuel.
Wheel Clutch Levers
Located below the right hand and left hand handles.
The wheel clutch levers allow the drive to momentarily
disengage to one or both wheels with the traction drive lever
still engaged. This allows easier turning and maneuvering
the machine (Figure 5).
G021739
Squeezing both wheel clutch levers simultaneously disengages
the drive to both wheels (free-wheeling). This enables you to
manually move the machine backward without stopping to
shift it into a reverse gear. It also allows you to maneuver
and transport the machine more easily when the engine is
not running.

4. To stop the broom, release the right hand lever.
• Do not operate the machine if the broom drive
lever is not functioning properly. Contact your
authorized Toro dealer.
Checking the Sweeping Path
A broom sweeps with the tips of its bristles. When too much
down pressure is applied, the broom is no longer using its
tips; the broom is now working with the sides of the bristles.
This limits the flicking action of the bristles, sweeping
effectiveness, and can decrease broom life.
WARNING
The rotating broom can throw stones and other
foreign objects, causing serious personal injury to
the operator or to bystanders.
1. Drive to a flat dusty area and stop the machine.
2. With the engine running move the throttle midway
between Slow and Fast. Engage the broom and allow
the broom to sweep for approximately 30 seconds.
• Keep the working area clear and free of all
objects that the broom could pick up and throw.
3. Disengage the broom and stop the engine.
• Keep all children and pets away from the area
of operation.
4. Wait for all moving parts to stop before leaving the
operating position.
5. Turn the engine On/Off switch to the Off position.
6. Make sure the area swept equals the length of the
broom and a maximum width of 51-102 mm (2-4
inches).
CAUTION
When the broom is engaged, it may drive the unit
in the reverse direction. If the broom height is
adjusted too low, the machine may move more
forcefully in the reverse direction, causing injury
and/or property damage.
Carefully check the broom height and adjust it
properly or contact your authorized Toro dealer.
