How to start the Tornado 7121 HWSY tractor?

Sit down, put the transmission in neutral, disengage the cutting units, engage the parking brake, set the throttle to maximum, insert the starter if engine is cold, turn the key to start position. Release the key after starting and disengage the starter.

How to adjust the cutting height?

Use the adjustment lever (position A for raised, B for lowered) and the rotary knob to choose a height between 2 and 10 cm. For models with single lever, 7 positions from 3 to 9 cm are available.

What to do if the engine does not start?

Check that the key is in the ON position, the battery is charged, the parking brake is engaged, the cutting units are disengaged, and the transmission is in neutral. Consult chapter 14 of the manual for other causes (fuse, battery, etc.).

How to empty the grass bag?

Disengage the cutting units, reduce engine speed, stop the machine, engage the parking brake. For manual control, pull out the lever and tilt the bag. For electric control, hold down the tilt button. Close the bag until the hook clicks.

What types of accessories are available for this tractor?

Mulching kit, battery charger, towing kit, protective cover, rear weight kit, rear discharge protection, snow chains, mud/snow wheels, trailer, spreader, lawn roller, snow plow, front sweeper, shredder, front rake, lift interface, and power take-off.

How to use the cruise control?

When moving forward, pull the fist grip control to activate cruise control. Speed is maintained without pressing the pedal. To deactivate, press the brake or accelerator pedal. Do not deactivate by pushing the control.

How to maintain the battery?

Fully charge the battery before first use, before a period of inactivity longer than 30 days, and after a long idle period. Use a suitable charger. Check connections and for corrosion.

How to store the machine for winter?

Empty the fuel tank, disconnect the battery, carefully clean the machine, lower the cutting units, engage the parking brake, remove the key. Store in a dry place protected from the weather, preferably under a cover.

How to change the cutting blades?

This operation must be performed by an authorized center. The manual recommends replacing the blades every 100 hours or as they wear. Only use original parts.

What to do if a red light comes on on the dashboard?

Consult the manual to identify the light. For example, a flashing oil indicator indicates a lubricating defect: stop the engine immediately, check the oil level. A battery indicator on while engine is running indicates a charging defect. Contact an authorized center if the problem persists.
