IMPORTANT: READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS AND CAUTIONS. 

USE THIS JACK CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE 

OR PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. RETAIN THESE INSTRUCTIONS FOR FUTURE USE.

  1.   SAFETY PRECAUTIONS

  

2.   SPECIFICATION

3.1.  Before first use.

3.1.1. Assemble the handle by lining up the holes in the two-piece  

 

handle and fasten with the assembly screw. 

3.1.2. Loosen location bolt at the back of the handle base. Insert the  

 

jack handle and tighten the bolt.

3.1.3. Before using jack, purge the hydraulic unit in order to eliminate  

 

any air in the system. Open the valve by turning the handle  

 anti-clockwise 

(fig.1)

, and pumping 8 or 9 times. When  

 

complete, close the release valve by turning the handle fully  

 clockwise 

(fig.1).

3.1.4. Place a few drops of hydraulic jack oil onto the pump piston  

 

and pump the handle several times to distribute the oil.  

 

Thoroughly lubricate all moving parts.

3.2.  General jacking. 

p

 

WARNING!

 Before lifting ensure Section 1 safety instructions  

 

are read and understood. 

3.2.1. Prepare the vehicle as mentioned in the safety instructions  

 

ensuring the ground on which the jack is to stand is level and  

 

solid (not tarmacadam) and use chocks under wheels of  

 vehicle.

3.2.2. Position the jack saddle under the vehicle manufacturer’s  

 

recommended lifting point. 

3.3.  Jacking the vehicle.

3.3.1. Turn the handle clockwise to close the release valve 

(fig.1)

  

 

and commence pumping handle up and down until the jack  

 

saddle reaches the vehicle jacking point. Check the jacking  

 

point is centrally located on the saddle and continue to pump  

 

the handle to raise the vehicle.

3.3.2. Should the jack become overloaded, a safety excess pressure  

 

valve will open and stop the jack from lifting.

p

 

WARNING!

 The jack is a lifting device only and must not be  

 

used to support the load. Use correctly rated axle stands to  

 

support the load.

3.4.  Lowering the vehicle.

p

  

WARNING! 

Ensure there are no persons or obstacles beneath  

 

the vehicle, or in the path of it's descent.

 

3.4.1. Raise the jack high enough for the axle stands to be easily  

 

removed. Then turn the handle slowly anti-clockwise to open the  

 

release valve 

(fig.1)

.

3.4.2. The lowering speed is controlled by the amount the release  

 

valve is opened. Lower carefully, avoiding any sudden  

 

changes in descent rate which could shock load the hydraulic  

 system. 

  3.  OPERATING INSTRUCTIONS

3

  

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 unapproved parts  

 

may be dangerous and will invalidate the warranty.

3

 

Locate the jack in a suitable, well lit working area.

3

 

Keep working area clean and tidy and free from unrelated  

 materials.

3

 

Use jack on level and solid ground, preferably concrete. Avoid  

 

tarmacadam as jack may sink in.

3

 

Place chocks under wheels of vehicle (but ensure wheels of  

 

jack can move freely).

3

 

Ensure the vehicle's handbrake is engaged, the engine is  

 

switched off and transmission is in gear (or “PARK” if automatic).

3

 

Ensure minimum distance of 0.5m between vehicle and static  

 

objects such as doors, walls, etc., to allow for vehicle tilting.

3

 

Ensure there are no passengers in the vehicle.

3

 

Ensure all non-essential persons keep a safe distance whilst  

 

the jack is in use.

3

 

Only place jack under vehicle manufacturer’s recommended  

 

lifting points 

(see vehicle handbook).

3

 

Check the lifting point is stable and centred on the jack saddle.

3

 

Ensure the jack wheels are free to move and that there are no  

 obstructions.

3

 

Use correctly rated axle stands under the vehicle before  

 

proceeding with any task.

3

 

Ensure there are no persons or obstructions beneath the  

 

vehicle before lowering.

3

 

Use a qualified person to maintain or repair the jack hydraulic  

 system.

 

IMPORTANT!

 During the jacking operation, ensure that the  

 

vehicle-to-jack saddle contact point are always visible.
