Original Instructions (EN)

It is a violation of California Public Resource Code Section 4442 to use or operate the engine on any forest-covered, brush-covered, or grass-covered land without a spark arrester muffler maintained in working order, or the engine constricted, equipped, and maintained for the prevention of fire. Other states or federal areas may have similar laws.

Because in some areas there are local, state, or federal regulations requiring that a spark arrester be used on the engine of this machine, a spark arrester is available as an option. If you require a spark arrester, contact your Authorized Service Dealer. Genuine Toro spark arresters are approved by the USDA Forestry Service.

The enclosed engine owner's manual is supplied for information regarding the US Environmental Protection Agency (EPA) and the California Emission

Control Regulation of emission systems, maintenance, and warranty. Replacements may be ordered through the engine manufacturer.

Controls

Choke Lever

Before starting a cold engine, move the choke lever (Figure 5) to the left. After the engine starts, regulate the choke to keep the engine running smoothly. As soon as possible, move the choke lever all the way to the right.

Note: A warm engine requires little or no choking.

Throttle Lever

The throttle lever (Figure 5) is located on the engine and controls the engine speed. Moving the throttle lever rearward increases the engine speed, and moving the throttle lever forward decreases the engine speed.

Engine On/Off Switch

The engine on/off switch (Figure 5) is located on the front right-hand side of the engine. Rotate the switch clockwise to the ON position before starting the engine. Rotate the switch counterclockwise to the OFF position to shut off the engine.

9

Fuel-Shutoff Valve

The fuel-shutoff valve (Figure 5) is located on the engine and is used to shut off the fuel when the machine will not be used for a few days, during transport to and from the jobsite, and when parked inside a building.

Rotate it down to open it or up to close it.

Self-Propel Drive Bail

The self-propel drive bail (Figure 6), located under the handle, controls the forward and reverse motion of the machine.

When you squeeze the self-propel drive bail is against the handle, the ground speed of the machine changes based on the distance between the bail and the handle. When you release the bail, the machine stops moving.

Blade-Control Lock

The blade-control lock (Figure 6) is located on the left side of the handle, next to the blade-control bail.

Moving the blade-control lock into the full forward position allows the blade-control bail to be squeezed against the handle.

Squeezing the blade-control bail against the handle engages the blade. Releasing the blade-control bail automatically disengages the blade. The blade-control lock resets to lock the blade-control bail.

Seeder-Control Lever

The seeder-control lever (Figure 6) is located on the right handle bar.

Push the lever forward to start the seed flow, and pull it rearward to stop the seed flow.

Parking Brake

Set the parking brake whenever you leave the machine unattended and when performing maintenance. To engage the parking brake, pull the brake rod out and down, locking it in the out position. To disengage the brake, pull the brake up until it snaps back into the machine.

Blade-Control Bail

The blade-control bail (Figure 6), located in front of the handle, engages or disengages the blade.

If the engine is running, the blades engage when you squeeze the blade-control bail toward the handle.

When you release the blade-control bail, the blades stop.

Hydrostatic-Drive Bypass Lever

The hydrostatic-drive bypass lever (Figure 8) releases the hydrostatic-drive system so you can move the machine by hand, without the engine running.

For normal operating position, pull up on the handle and push the handle in until all 3 notches are inside the frame.

Note: The last notch on the handle does not latch on the slot.

To release the drive wheels, pull up on the handle and pull it out until the last notch engages in the slot. Then push the handle down.
