NOTES : The numbers in brackets refer to diagram on page 4

When this jack leaves the factory the oil chamber contains the correct amount of oil. Before using for the ﬁrst time,

remove the oil reservoir plug (6) and check the oil level. The oil level should be within 3mm of the bottom of the ﬁller

hole.

USE ISO GRADE 10 TO 15 HYDRAULIC JACK OIL

Sometimes during shipment or when changing the oil, air may get trapped in the hydraulic system causing poor

performance. To purge any air from the system and with the jack in an upright position, open the oil reservoir plug (6),

place a cloth over the ﬁller hole and pump the handle 7 to 10 times in quick succession. This will purge any air from

the system.

WARNING

THE JACK SHOULD BE USED ON LEVEL FIRM GROUND

WHEREVER POSSIBLE. DO NOT GET UNDER A VEHICLE

THAT IS SUPPORTED BY A JACK. USE VEHICLE SUPPORT STANDS.

WARNING: INCORRECT USE MAY RESULT IN POSSIBLE

LOSS OF LOAD, DAMAGE AND PERSONAL INJURY.

SAFE USAGE INSTRUCTIONS

IT IS RECOMMENDED THAT:

1. Before lifting the vehicle consult the vehicle owner manual for the correct lifting and support points

2. The jack should be used for lifting and lowering only. The raised vehicle should be supported on properly

rated vehicle support stands

3. Ensure the load to be lifted does not exceed the capacity of the jack

4. The jack should be used on level ﬁrm ground wherever possible

5. The gear shift must be in 'Park' for automatic transmission and 1st gear for manual

6. The hand brake is fully applied

7. The un-lifted wheels are chocked

8. Position the Head Cap centrally under the load or lifting point, ensuring the load is applied through the centre

of the Head Cap

9. No person should remain in the vehicle that is to be jacked

Page 3

1. TO RAISE THE LOAD

a. With the jack in the lowered position turn the release valve (04), with the end of the jack handle (34) in a

clockwise direction until it is ﬁrmly closed.

b. To maximize the lifting height, unscrew the extension screw /head cap (24) to the required height.

c. Insert the handle into the handle sleeve (17) and raise the ram (25) by operating the handle up and down until

contact is made with the lifting point.

d. Position the Head Cap centrally under the load or lifting point and ensure the load is applied through the centre

of the head cap. NB. Off-centre loads and loads lifted while jack is not sitting level may result in damage and/or

injury.

e. Pump the handle up and down to raise the load to the required height.

f. Place support stands in the correct position under the load.

g. Slowly turn the release valve counter clockwise, just sufﬁciently to allow a gradual decent of the load onto the

support stands.

2. TO LOWER THE LOAD

a. Close the release valve (04). Operate the jack to raise the ram to the correct position under the vehicle. Raise

the load until the support stands are free. Remove the stands clear of the load.

b. Slowly turn the release valve counter clockwise using the end of the handle, just sufﬁciently to allow a gradual

decent of the load. If the ram is still partially raised after the load has fully descended, slowly open the release

valve one full turn and push the ram down to its lowest position.

BEFORE USE : Visually inspect the jack for any abnormal conditions and refer to the preceding.

WARNINGS, SAFE USAGE STATEMENTS and NOTES.

A. OPERATING INSTRUCTIONS

B. GENERAL CARE OF YOUR JACK

1. When jack is not in use, lifting Ram (25), Handle Sleeve (i 7) and the extension screw (24) should be in the fully

lowered position. This will protect precision machined surfaces from corrosion

2. Keep your jack clean and lubricate the pumping collar and extension screw.

3. Service kits: These are available and comprise the necessary washers and seals which would be required for a

general overhaul of the hydraulic unit.

4. To add oil; with the ram fully lowered set the jack in an upright position. Wipe away any oil or foreign matter from

around the oil reservoir plug (33) then remove it. The oil level should be 3mm below the ﬁller hole. Use only ISO

Grade 1O to 15 Hydraulic Jack oil.

5. Oil Change; For best performance and longest life replace the complete oil supply at least once per year. Lay the

jack on its side and allow the oil to run out into a suitable drain pan. The oil will run slowly as air must enter as

the oil drains out. Be careful not to let dirt or foreign matter to get into the system.

PURGING AIR FROM HYDRAULIC SYSTEM

Occasionally, air bubbles become trapped inside the jack, reducing its efﬁciency.

Bleed air out of the jack’s hydraulic system as follows:

1. Open release valve, remove oil plug.

2. Operate pump rapidly several times to force air out.

3. Close release valve, replace oil plug.

Jack should now operate normally. If not, repeat purging procedure as needed.

Page 4

1. IF JACK WILL NOT RAISE OR LIFT LOAD

a. Before attempting to locate the speciﬁc trouble, inspect oil level in the following manner. Place jack vertically on a level

surface. Open release valve (04). Fully lower the lifting Ram (25). Wipe away any oil or other contaminants from the Oil

Reservoir Flag (33) and remove. Correct oil level should be 3mm below the oil ﬁller hole. If lacking oil, ﬁll to the correct level

using ISO Grade 10 to 15 Hydraulic Jack Oil. Replace oil reservoir plug. Close release valve and pump the lifting ram up to it's

full height. Then open release valve and, with pressure on the Head Cap (24), force it to lower as rapidly as possible. Repeat

this operation three or four times. This procedure will thoroughly ﬂush the valves and ensure complete distribution of oil. In

most cases it will restore the jack to proper working order. Close release valve tightly and try jack under load.

b. The jack may have air trapped in the system. With the jack in the upright position ﬁrstly wipe away any oil or foreign matter

from around the oil reservoir plug then remove it. Purge any air from the system placing a cloth over the ﬁller hole and pump

the handle 7 to 10 times in quick succession. This will force the air out.

c. The plunger seal may be worn. Disconnect pivot pin (18) and remove pump assembly (8 to 16), and replace seal (09). Re-

assemble and try jack under load.

2. IF JACK WILL NOT LIFT FULL CAPACITY

a. The unit may have air trapped in the system. See instruction C. 1 (b).

b. The plunger seal may be worn. Ref. C I (c)

c. The discharge valve may have dirt under it or may need re-seating.

3. IF JACK LOWERS UNDER LOAD

a. The discharge valve may be held open by dirt on ball seat. When a dirty discharge valve or ball seat exists, the jack may lower

quickly, causing handle to ﬂy up with force. This is caused by the oil rushing back into the pump chamber through the open

ball seat. When this happens, it is advisable to repeat procedures i .a & 1.b before going through the partial disassembly of the

hydraulic unit. The discharge valve is located at the bottom of the ram cylinder.

b. Procedure to disassemble hydraulic unit: Fully open release valve (04). Remove oil reservoir plug (33) and empty oil into a

clean vessel. Remove top nut (31) and reservoir (22). Withdraw ram assembly (24 to 28). It is now possible to remove the

cylinder (06) using multi-grips. The discharge valve is located in the base, under the sealing washer. Remove the seal (05) and

the 5mm ball and then clean and check the valve seat. Wipe the ball and replace to re-seat the ball on its seat, place a 5mm

dia. X 75mm punch on top of ball and lightly tap it with a small hammer. Re-install the components, replace seal (05) and

screw in ram cylinder tightly. Replace top and bottom seals (21,30), install the ram assembly carefully and then screw in and

tighten the top nut.

c. Cup seal for the ram may be worn: This is likely only in jacks that have given very heavy service. Follow above procedure 2-(a)

until access to ram assembly is made. Remove worn seal (28) by pulling away or cutting with a small knife. Take caution not to

damage the new ram seal when installing.

d. Dirt in the release valve will cause jack to lower under load.

Remove release valve (02 to 04), clean valve seat and components and re-install.

4. IF THE JACK WILL NOT LOWER COMPLETELY

a. RAM: Hydraulic unit may contain too much oil. Remove oil reservoir plug (33) and check oil level. Oil should be 3mm below the

ﬁller hole when the ram is completely lowered.

b. EXTENSION SCREW: Screw thread may require cleaning, be damaged or bent.
