Page 7

WARNING: Read, understand, and follow all instructions and warnings on the machine and in this manual before operating.

Forward Tine Engagement Handle

The forward tine engagement handle is located beneath the tiller handle. Squeezing the handle up against the tiller handle engages the tines. Release the handle to stop the tines. See Figure 5.

Reverse Tine Engagement Lever

The reverse tine engagement lever is located on top of the handle panel. Pull the lever to the rear to move the tines in reverse. Release the lever to stop the reverse tine drive. See Figure 5.

NOTE: Never engage both the forward and reverse tine controls at the same time. Engaging both forward and reverse tine drives at the same time could damage the belt drives and cause the engine to stall.

Depth Stake

The depth stake is located in the rear of the tiller and it controls the tilling depth. See the Operating Your Tiller section for more details.

Tines And End Caps

The tilling tines and end caps are used to cultivate,

furrow, and prepare your garden for seeding. The end caps are used to avoid tilled soil from overflowing onto unwanted areas.

Handle Knob

The handle knob is attached to the handle brace and it is used to adjust the height of the handle to three different settings.

Throttle Control

The throttle control lever is located on the engine. It controls the engine’s speed and stops the engine.

With the throttle control pushed completely forward, the carburetor is in START or FAST position. Use maximum engine speed for deep tilling.

Pull the throttle control back to reduce engine speed to IDLE. Throttle control should be at IDLE for transporting the tiller.

Pull the throttle completely back to stop the engine.

Choke Lever

The choke lever is located near the throttle control. It is used to enrich the fuel mixture when starting a cold engine.

Engine Controls

See the separate engine manual for the location and function of other controls on the engine.

SECTION 4: OPERATING YOUR TILLER

WARNING: Read, understand, and follow all instructions and warnings on the machine and in this manual before operating.

Before Starting

Gas And Oil Fill-Up

Service the engine with gasoline and oil as instructed in the separate engine manual packed with your tiller. Read instructions carefully.

WARNING: Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel machine indoors or while the engine is hot or running.

Starting Engine

WARNING: Be sure no one is standing in front of the tiller while the engine is running or being started.

Attach spark plug wire to spark plug. Make sure the metal cap on the end of the spark plug is fastened securely over the metal tip on the spark plug.

Make certain the tine engagement controls are in the neutral position.

Place the throttle control in the FAST position.

Move choke lever to CHOKE position. A warm engine requires little or no choke.

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.

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. Repeat until engine starts.

When engine starts, move choke lever on engine halfway between CHOKE and RUN. As the engine warms up, move the lever to RUN position.

Stopping Engine

Move throttle control lever to STOP or OFF position.
