1. SAFETY PRECAUTIONS
2. INTRODUCTION / SPECIFICATION
3. ASSEMBLY
Ensure the jack is in sound condition and good working order.
Take action for immediate repair or replacement of damaged
parts. Use genuine parts only. The use of improper parts may be
dangerous and will invalidate the warranty.
Locate the jack in a suitable, well lit working area.
Keep working area clean and tidy and free from unrelated
materials.
Use jack on level and solid ground, preferably concrete.
Avoid tarmacadam as jack may sink in.
Chock wheels of vehicle.
Ensure the vehicle handbrake is engaged, engine is switched off
and transmission is in gear (or “PARK” if automatic).
Ensure minimum distance of 0.5m between vehicle and static
objects such as doors, walls, etc., to allow for vehicle tilting.
Ensure all non-essential persons keep a safe distance whilst the
jack is in use.
Ensure there are no passengers in the vehicle.
Place jack under only those lifting points recommended by
vehicle manufacturer (see vehicle handbook).
Check that the lifting point is stable and centred on the jack
saddle.
 Ensure the jack wheels are free to move and that there are no
obstructions.
 DANGER: Use the jack for lifting only, NOT for supporting the
lifted load.
 Ensure there are no persons or obstructions beneath the vehicle
before lowering.
Use suitable axle stands under the vehicle before proceeding with
any task.
Use a qualified person to lubricate and maintain the jack.
 Ensure that only hydraulic jack oil is used in the jack.
 DO NOT operate the jack if damaged.
 DO NOT allow untrained persons to operate the jack.
 DO NOT exceed the rated capacity of the jack.
 DO NOT allow the vehicle to move during lifting or lowering, or
use the jack to move the vehicle.
 DO NOT jack vehicle if there is a risk of spillage of fuel, battery
acid, or other dangerous substances.
 DO NOT work under the vehicle until appropriately rated axle
stands have been correctly positioned.
 DO NOT use the jack for purposes other than that for which it is
intended.
 DO NOT top up hydraulic system with brake fluid. Use hydraulic
jack oil only. (Sealey Part No: HJO500MLS or HJO5LS)

mechanism allows safer, more controlled lowering of the jack.
Profiled lifting arm gives low clearance height of just 95mm x 390mm
deep making this unit suitable for sports and custom cars. Heavy-duty
chassis with strengthening flanges along the top edge for extra
torsional rigidity under load. Fitted with heavy-duty one-piece
hydraulic unit with pump-through action preventing handle locking at
maximum ram extension. Large sized saddle aids positioning under
vehicle and safety valve prevents overloading. Supplied with foam
jacking sleeve to prevent damage to vehicles bodywork and integral
saddle pad.

IMPORTANT: Only fully qualified personnel should attempt
maintenance or repair.
6.1 Monthly Maintenance
Lubrication is critical to jacks, since they support heavy
loads. Any restriction due to dirt or rust can cause either
slow jack movement, or extremely rapid jerks, causing
damage to the internal components. To keep the jack well
lubricated, carry out the following steps.
6.1.1 Lubricate the ram, the linkages and the saddle and pump
mechanism with light oil.
6.1.2 Grease the wheel bearing and axles.
6.1.3 Keep all jack surfaces and warning labels clean.
6.1.4 Check and maintain the ram oil level (Section 6.3).
6.2 Three Monthly Maintenance
6.2.1 At three monthly intervals, check the ram for any signs of
rust or corrosion. Clean the ram as required and wipe with
an oil cloth.
6.3 Checking the Oil Level
6.3.1 Fully retract the ram by turning the release valve
counter-clockwise.
6.3.2 Undo the four top plate retaining screws and remove the top
plate.
6.3.3 With the jack in the level position, remove the oil filler plug.
6.3.4 The oil should be level with the bottom of the oil filler hole.
If it is not top up with clean hydraulic jack oil. (Sealey Part
No: HJO500MLS or HJO5LS)
6.3.5 Replace the oil filler plug (C) and check the jack operation.
6.3.6 Purge air from the hydraulic unit as required. Refer to
Section 4.
6.3.7 Replace the top plate and secure with the four screws.
NOTE: Always store the jack in the fully lowered position. This
will protect critical areas from excessive corrosion.
