4.3.2.
Turn release valve anticlockwise one full turn to open.
4.3.3.
Pump handle eight full strokes.
4.3.4.
Turn release valve clockwise to close valve.
4.3.5.
Pump handle until the ram reaches maximum height and continue to pump several times to remove trapped air in the ram.

Carefully and slowly move top of oil filler plug aside to release trapped air.
4.3.7.
Turn release valve anticlockwise one full turn and lower ram to its lowest position. Use force if necessary.
4.3.8.
Turn release valve clockwise to closed position and check for proper pump action. It may be necessary to perform the above more
than once to ensure the air is totally evacuated.
4.4.
LIFTING THE LOAD
4.4.1. Ensure the jack and vehicle are on a hard level surface.
4.4.2. Apply vehicle parking brake and chock the wheels.
4.4.3. Consult the vehicle owners manual to ascertain the location of jacking points and position jack beneath prescribed lifting point.
4.4.4. Turn the release valve clockwise to the closed position.
DO NOT
overtighten.
4.4.5. To raise the vehicle to the desired height, set the screw extension to the lifting point, place the handle into the socket and pump
up and down.
4.4.6. Place axle stands beneath the vehicle at locations recommended by the vehicle manufacturer.
DO NOT
get under the vehicle without
it being supported by axle stands. Jacks are NOT designed to maintain heavy loads for long periods of time.
DO NOT
attempt to put
axle stands simultaneously under both ends of the vehicle or under one side of the vehicle.
4.4.7. Turn release valve SLOWLY anticlockwise to lower the load onto jack stands.

5. MAINTENANCE
IMPORTANT! REPAIR AND MAINTENANCE OF THE JACK TO BE CARRIED OUT BY FULLY QUALIFIED PERSONNEL ONLY
WARNING! DO NOT
use brake fluid, or any fluid other than Sealey hydraulic jack fluid. Use of non preferred jack oil may cause
damage and invalidate the warranty.
5.1.
INSPECTION
5.1.1.
The product must be maintained in accordance with these instructions. No alterations must be made to the product.
5.1.2.
Before use a visual inspection should be made for abnormal conditions such as cracked welds, damage, bent, worn loose or
missing parts or hydraulic leaks.
5.1.3.
Inspection shall be performed in accordance with this manual.
5.1.4.
The product shall be inspected immediately if the jack is believed to have been subject to abnormal load or shock.
5.1.5.
It is recommended that inspection should carried out by properly qualified personnel.
5.2.
MAINTENANCE
5.2.1.
Monthly maintenance is recommended. Lubrication is critical to jacks as they support heavy loads. Any restriction due to dirt,
rust, etc. can cause either slow movement or cause extremely rapid jerks, damaging the internal components. The following steps
are designed to keep the jack well lubricated.
5.2.1.1. Lubricate the ram, linkages, saddle and pump mechanism with light oil.
5.2.1.2. Visually inspect for cracked welds, bent, loose or missing parts or hydraulic oil leaks.
5.2.1.3. If jack is subjected to abnormal loads or shock, remove from service and have it examined by an authorised repair specialist.
5.2.1.4. Check all surfaces and maintain all labels and warnings.
5.2.1.5. Check and maintain the ram oil level.
5.2.1.6. Check ram every 3 months for any sign of rust or corrosion. Clean as needed and wipe with an oily cloth. When not in use always
leave with the ram fully retracted. This will help protect critical areas from excessive corrosion.
8
DO NOT
use brake or transmission fluids or regular motor oil as they will damage the seals. Always use Sealey hydraulic jack fluid.
Use of non preferred jack oil may cause damage and invalidate the warranty.
5.3.
CHECK OIL LEVEL
5.3.1.
Turn release valve counterclockwise to allow ram to fully retract. It may be necessary to apply force to the saddle to lower it.
5.3.2.
With the jack in a level position, remove the oil filler plug. Stand the jack in a vertical position with the handle socket down. The oil
should be level with the bottom of the filler hole. If not top it up.
DO NOT
overfill. Always fill with new, clean hydraulic oil.
5.3.3.
Replace the oil filler plug.
5.3.4.
Check jack operation.
5.3.5.
Purge air from the system as required, refer to section 4.3.
