Frequently Asked Questions - 51157 WilTec

How do I assemble the WilTec 51157 jack?

Position the jack on a flat surface. Expand the steel rod and secure it with three screws. Install the handle by tightening it. Remove the locking peg and place the crankshaft upwards. It is recommended to grease the shaft before first use.

What is the maximum weight capacity of model 51157?

The maximum capacity is 250 kg (550 lbs). Do not exceed this limit to avoid damage or injury.

How should I position the lawn mower on the jack?

Place the lawn mower above the jack with its base parallel to the lateral reinforcement bar opposite the crank handle. For ride-on mowers, the back wheels should be placed on the jack. Ensure the wheel is stable against the lateral bar before lifting.

What safety precautions should I take when using this jack?

Only use on flat, hard ground. Never leave the jack unattended with a load. Keep children and bystanders away. Always visually inspect before use. Ensure the driver has left the seat before lifting a ride-on mower. Do not lift higher than necessary.

How do I lower the jack after use?

Rotate the crank handle counter-clockwise to lower the mower. Once lowered, remove the locking bracket, fold the crankshaft downward, and secure it with the bracket for storage.

How often should I lubricate the jack?

Grease the shaft approximately every three months. Also lubricate after any sign of stiffness or if the jack has been exposed to moisture.

Can this jack be used for vehicles other than lawn mowers?

No, this jack is specifically designed for lawn mowers. Using it for other vehicles may cause instability and injury.

What is the maximum lift height?

The manual does not specify a maximum lift height, but it advises to lift only as much as necessary for the task to prevent the mower from falling over.

How should I store the jack when not in use?

Store in a dry, clean place to prevent rust. Fold the crankshaft down and secure it with the bracket. Periodically check for rust and wipe with an oiled cloth if needed.

Returns Department

Thank you for purchasing this quality product. To minimise the risk of injury we urge that our clients take some basic safety precautions when using this device. Please read the operation instructions carefully and make sure you have understood its content.

Keep these operation instructions safe.

Attention! Before lifting an object, make sure you are fully aware on how the jack works. The inadequate use can cause serious injury. All other uses than the ones outlined here can damage the device and can be dangerous.

Safety requirements

• Only use the lawn mower jack for lifting.
• Do not allow children to use or play with the device.
  • At no time leave the mower jack unattended and keep children and by-standers away.
• Never overcharge the mower jack. Overcharging may damage the mower jack and/or cause a defect, resulting in serious injury.
• The mower lift is designed for a flat and hard ground. Using it on a soft surface can cause instability, making the whole construct fall over.
• Always secure the load on the lateral reinforcement located on the side opposite the hand crank. The load should always be placed horizontally on the mower jack to avoid damage and sliding or falling of the load.
  • Always visually check the jack before use, without any objects on it.
  • Before lifting a ride-on mower, make sure that the driver has left the seat.

Use

Assembly before use

1. Position the jack on a flat and stable surface.
2. Expand the steel rod and secure it with three screws.
3. Install the handle and tighten it by screwing it on.
4. Remove the locking peg.
5. Place the crankshaft upwards.
6. For a better use we recommend to grease the shaft before use. This should be repeated when required to ensure the smooth functioning of the parts.

Assembly during use

1. Remove the locking bracket (1) to be able to lift the crankshaft into an upright position (2).
2. Then place the locking bracket back into place, allowing the crankshaft to be sturdily positioned upright (3).
3. Then turn the hand crank clockwise enabling for the lawn mower to be lifted (4).

Lifting a lawn mower

1. Place the jack on a flat and hard surface.

2. Position the lawn mower above the jack. The base of the lawn mower needs to be parallel to the lateral reinforcement bar opposite of the crank handle (5).

3. Caution: When lifting a ride-on mower, the back wheels need to be placed on the jack.

4. The wheel of the lawn mower needs to be positioned stably against the lateral reinforcement bar (5).

5. The crank handle needs to be rotated clockwise to lift the mower 2–3 cm.

6. Then ensure that the mower is positioned securely before lifting it even higher.

- In case the mower was placed wrongly, rotate the crank handle counter-clockwise, to place the mower onto the ground again. Reposition the mower and try lifting it up cautiously again.

- Caution: Do not lift the lawn mower too high up, it might fall over. Only lift it as much as necessary and to be able to carry out the required work.

Maintenance

If the jack is not in use, the crank shaft should be folded downward and secured with the bracket. Approximately every three months, the shaft needs to be greased, during this process the jack should be checked for any damage. If rust has collected anywhere, the area needs to be wiped off with an oiled cloth to ensure the jack is still in an adequate condition for use. Storing the jack in a dry and clean place is recommended to prevent rust from collecting or other damages to occur.
