4. PreParation
4.1.
connect air supply
4.1.1.
An in-line filter is recommended, drain daily. Drain compressor tank daily.
4.1.2.
Before connecting air supply hose ensure trigger is not pressed down.
4.1.3.
Ensure constant air pressure is maintained during operation: 7-10 kg/cm² and a minimum air flow of 28ltr/min.
4.2.
bleed system
4.2.1.
Prior to using the jack, eliminate any air that may have accumulated in the system.
4.2.2.
Position the lever in the release valve and turn once in an anti-clockwise direction.
4.2.3.
Place the lever into the lever support and pump the jack several times to ensure internal lubrication and the elimination of accumulated
air. Alternatively, press trigger A of the valve briefly.
4.2.4.
Place the lever in release valve again and close it in a clockwise direction.
4.2.5.
Jack is now ready for operation.
5. oPeration
iMPortant! Prior to lifting the load ensure that all of the above safety instructions are followed.
5.1.
the feed screw of the jack, compliments its stroke,
do not
fully extend it.
5.2.
liFtinG
5.2.1.
close the release valve fully and press trigger of the air hose. lifting may also be performed by fully moving the lever downwards to
obtain greater speed by using the full stroke range of the piston.
5.3.
loWerinG
5.3.1.
slowly turn the release valve in an anticlockwise direction using the lever. ensure that there are no persons or obstacles under the
vehicle to be lowered.
5.3.2.
the lowering speed is controlled by the amount of the valve is opened.
5.3.3.
during lowering air is eliminated through a small hole in connector c, this is normal.
5.4.
Should the jack be overloaded, it is fitted with an overload valve which will prevent the
vehicle from being lifted.
5.5.
never move the jack with the lever in the release valve as this will cause damage.
5.6.
do not
attempt to move the jack by pulling on the plastic air supply tube.
6. Maintenance
iMPortant!
Both the maintenance and repair of the jack may only be performed by
qualified persons, who have sufficient knowledge of the hydraulic systems used in these
devices as a result of their training and experience.
6.1.
Keep the jack clean and lubricate all moving parts at regular intervals, which must be clean and protected from aggressive conditions
at all times.
6.2.
only original spare parts should be used.
6.3.
Prior to each use, check for bent, broken, cracked or loose parts and solve the problem. if it is suspected that the jack has been
subjected to abnormal loads or has suffered any knocks, withdraw it from service until the problem has been rectified.
6.4.
If the oil level needs to be checked or refilled, with the piston fully retracted, remove the filler plug and drain its contents into a
container.
6.5.
Refill with oil. Use a good quality oil such as Sealey hydraulic jack oil.
do not
use brake fluid. Bleed system as in section
4.2. Replace oil filler plug. Ensure no dirt enters the hydraulic system when draining, filling removing or replacing components.
Annual oil replacement is recommended for jacks in daily use.
iMPortant
too much oil may render the jack inoperative.
6.6.
