Table of contents
Product Overview
The Sealey 1050CXHV is a 2-tonne short chassis trolley jack designed for hobbyist use or as an emergency mobile jack. It features a robust steel chassis with welded castor supports and a one-piece hydraulic unit. The unit is equipped with an overload valve, a carry handle, and a finger cover for enhanced safety during operation. The jack is designed for lifting vehicles only and must not be used to support a load for extended periods.
Safety Precautions
Safety is paramount when operating hydraulic lifting equipment. Always ensure the jack is in good working order before use. Operate the jack on level, solid ground, preferably concrete, to prevent sinking. Before lifting, ensure the vehicle handbrake is engaged, the engine is off, and the transmission is in gear or in park. Always use axle stands to support the vehicle once it has been lifted to the desired height. Never exceed the rated capacity of 2 tonnes. Keep the working area clean and ensure no passengers are inside the vehicle during the lifting process.
Operation and Assembly
To assemble, insert the handle into the jacking socket and engage the external pin. Before the first use, it is essential to purge the hydraulic system to remove any trapped air. This is done by opening the release valve, placing the handle in the jacking socket, and pumping for 30 to 40 seconds. To lift a vehicle, close the release valve by turning it clockwise, position the saddle under the manufacturer-recommended lifting point, and pump the handle until the desired height is reached. To lower the vehicle, slowly turn the release valve anti-clockwise. The speed of descent is controlled by how far the valve is turned; avoid sudden movements to prevent shock loading the hydraulic system.

Maintenance and Care
Regular maintenance is required to ensure the longevity of the jack. Keep the unit clean and lubricate all moving parts periodically. Before each use, inspect the jack for any signs of damage, such as cracks, bent parts, or loose fasteners. If any damage is found, remove the jack from service immediately. Check the hydraulic oil level annually and top up if necessary using only high-quality hydraulic jack oil. Never use brake fluid, as this will damage the internal seals and invalidate the warranty. When not in use, store the jack in a fully lowered position in a dry, childproof area.

Common problems
Check for overload, low oil level, or air in the system. Ensure the release valve is fully closed.
This usually indicates air in the system. Open the release valve and pump the handle several times to purge air.
The release valve may be partially open or there may be dirt on the valve seats. Clean or check the valve.
Check for lack of lubrication on moving parts or a bent piston rod. Ensure the release valve is fully open.
Before use
- Ensure the jack is on level, solid ground.
- Check that the vehicle handbrake is engaged.
- Verify the jack is in good working order with no visible damage.
- Ensure the lifting point is correctly identified.
- Have axle stands ready for support.
- Purge the hydraulic system of air before first use.
- Ensure no passengers are in the vehicle.
