Maintain correct balance and footing, DO NOT over reach. Ensure the floor is not slippery and wear non-slip shoes.
Before lifting check that there are no overhead obstructions.
When platform has been raised to the working height ensure the locking pin is engaged to prevent accidental lowering.
Keep children and unauthorised persons away from the work area.
The lowering speed will vary according to the weight of the load and the setting of the release valve.
To avoid injury, be fully aware of your own and other persons locations in relation to the lifting, and lowering, of the load.

OPERATION

WARNING! Ensure that you read, understand and apply the safety instructions before use.
WARNING! DO NOT overload the lift.
5.1. BLEEDING
IMPORTANT! Before first use, check for proper hydraulic fluid level in the ram. Thoroughly test the jack for proper operation prior to use. If the jack appears not to be working properly, it may be necessary to bleed it’s hydraulic system of excess air.
5.1.1. Remove the bottle jack from the ATV/Mover lift.
5.1.2. Locate the oil fill plug on the side of the bottle jack and remove it. Drain the old oil from the hydraulic system.
5.1.3. Top up the hydraulic system using hydraulic oil and replace the oil fill plug after.
5.1.4. Test the jack several times for proper operation before attempting to lift a load. If the jack still does not appear to be working properly after bleeding, DO NOT USE the jack until it has been repaired by a qualified service technician.
5.1.5. LIFTING
WARNING! Set jack and vehicle on a flat, level, hard, ground surface safely away from oncoming traffic. Turn off vehicles engine. Also place the vehicle’s transmission in ‘Park’ (if automatic) or in it’s lowest gear (if manual). Set the vehicles emergency brake. Then, chock the wheels that are not being lifted.
5.1.6. Determine the wheel width of the ATV/mower, and adjust the wheel bracket supports to match that width. Lock them in place using the width pins. WARNING! Adjust them so they are equally spaced from the center of the jack. Failing that the jack will be unstable and might tip.
5.1.7. Examine the bottom of each ATV/mower wheel that is touching the floor. Adjust the depth of both wheel brackets to be slightly larger than that distance of the wheels.
5.1.8. Turn the release valve counter-clockwise to lower the jack. Once the jack is fully lowered, turn the release valve clockwise completely.
5.1.9. Use the ATV/mower’s steering to straighten it’s wheels. Use wheel chocks (sold separately) to block the wheels on the opposite end of the mower/ATV.
5.1.10. Press the front of the wheel brackets straight against the front of the ATV/mower’s wheels. Push the wheel brackets under the wheels until both wheels rest in the center of the wheel bracket.
5.1.11. Place the two safety lock levers, refer to (34) in the closed, locked position to enable the locking mechanism. (See fig.2).
5.1.12. Pump the handle, use smooth, full strokes for best results.
5.1.13. Raise the vehicle to the desired height. As the load is lifted the locking mechanism will automatically engage to lock the lift arm in one of three positions.
5.1.14. Make sure the lift arm is locked in one of the three available positions before working on the ATV/mower.
5.2. LOWERING
5.2.1. Remove all tools, parts, etc. From under the vehicle.
5.2.2. Pump the handle slightly to remove weight from the locking mechanism.
5.2.3. Keep clear and slowly turn the hydraulic release valve counter- clockwise to lower the ATV/mower lift.
5.2.4. Once the jack is completely lowered, remove it from under the ATV/mower lift.
5.2.5. When not in use, store jack in a safe, dry location out of reach of children.
5.3. TRANSPORTATION, HANDLING OF THE MACHINE
