Steps

  1. Pull over well off the road and switch on your hazard lights. Choose flat, firm ground, not soft dirt or a slope, and apply the handbrake.

  2. Loosen the wheel nuts about half a turn with the rattle gun or wheel brace while the tyre is still on the ground.

  3. Connect the Ezi-Jak power cables to your vehicle battery or 12V socket as the kit instructs, then check the jack and compressor power on.

  4. Place wheel chocks in front of and behind a wheel on the opposite side. Never put any part of your body under the car until it is supported.

  5. Slide the electric hydraulic jack under the vehicle's jacking point shown in your manual. Line up the saddle so it sits flat and square on the point.

  6. Press the jack switch to raise the vehicle until the flat tyre clears the ground by a few centimetres. Keep clear of the car as it lifts.

  7. Remove the wheel nuts with the rattle gun and pull the flat tyre straight off the hub. Set it aside.

  8. Lift the spare onto the hub, line up the bolt holes and push it on. Hand-tighten the nuts, then snug them with the rattle gun.

  9. Lower the jack until the tyre touches the ground, then tighten the wheel nuts firmly in a star pattern. Check them again after 50 km.

  10. Use the built-in air compressor to inflate the spare to the pressure on the tyre placard or in your manual. Pack the kit away.

Tips and common mistakes

Never jack up a car on grass, gravel or a slope, and always use chocks on the opposite wheel.

Loosen the wheel nuts before lifting the car, or the wheel will spin.

Check the spare's pressure before a long trip, since spares slowly lose air.

Re-torque the wheel nuts after about 50 km of driving.

Questions

Can I use the Ezi-Jak on a caravan or trailer?

Yes, the kit is sold for cars, 4WDs, caravans, camper trailers and trailers. Check the jack's rated capacity against your loaded weight before lifting.

Do I need to loosen the wheel nuts before jacking?

Yes. Break the nuts loose about half a turn while the tyre is still on the ground, then lift the car.

How do I power the Ezi-Jak?

It runs from your vehicle's 12V power through the supplied cables. Connect it as the kit instructions show before switching on the jack or compressor.
