Thank you for purchasing a National Machinery product. This product is produced and manufactured to a high standard of dependability and
will, if used according to these instructions and properly maintained, give you years of trouble free performance.
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.
pWARNING! 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.
pWARNING! 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.
pWARNING! 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
3Ensure 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.
3Locate the jack in a suitable, well lit working area.
3Keep working area clean and tidy and free from unrelated
materials.
3Use jack on level and solid ground, preferably concrete. Avoid
tarmacadam as jack may sink in.
3Place chocks under wheels of vehicle (but ensure wheels of
jack can move freely).
3Ensure the vehicle's handbrake is engaged, the engine is
switched off and transmission is in gear (or “PARK” if automatic).
3Ensure minimum distance of 0.5m between vehicle and static
objects such as doors, walls, etc., to allow for vehicle tilting.
3Ensure there are no passengers in the vehicle.
3Ensure all non-essential persons keep a safe distance whilst
the jack is in use.
3Only place jack under vehicle manufacturer’s recommended
lifting points (see vehicle handbook).
3Check the lifting point is stable and centred on the jack saddle.
3Ensure the jack wheels are free to move and that there are no
obstructions.
3Use correctly rated axle stands under the vehicle before
proceeding with any task.
3Ensure there are no persons or obstructions beneath the
vehicle before lowering.
3Use 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.
pDANGER: Use the jack for lifting only, NOT for supporting the
lifted load.
7DO NOT operate the jack if damaged.
7DO NOT allow untrained persons to operate the jack.
7DO NOT exceed the rated capacity (3Tonne) of the jack.
7DO NOT allow the vehicle to move while supported by the
jack, or use the jack to move the vehicle.
7DO NOT jack vehicle if there is a risk of spillage of fuel, battery
acid, or other dangerous substances.
7DO NOT work under the vehicle until suitably rated axle stands
have been correctly positioned.
7DO NOT use the jack for purposes other than which it is intended.
7DO NOT top up hydraulic system with brake fluid. Use
hydraulic jack oil only.
7DO NOT adjust the safety overload valve.
3When not in use, store jack, fully lowered, in a safe, dry,
childproof area. fig.1

INSTRUCTIONS FOR:
TROLLEY JACK 3 TONNE
STANDARD CHASSIS
MODEL No: NA3010

Original Language Version
4.1. When the jack is not in use, the ram and the handle socket
should be in their lowest positions to minimise corrosion.
Remove the handle to deactivate the jack.
4.2. Keep the jack clean and lubricate all moving parts on a
regular basis, pump grease into the grease nipple (fig.2).
4.3. Before each use, check for broken, cracked, bent, or loose
parts, or any visible damage to ram, pump, saddle, lifting
arm, frame and all parts including nuts, bolts, pins and other
fasteners. If any suspect item is found remove jack from
service and take necessary action to remedy the problem.
DO NOT use the jack if believed to have been subjected to
abnormal load or shock load.
4.4. Periodically check the pump piston and piston rod for signs
of corrosion. Clean exposed areas with a clean oiled cloth.
4.5. After one year the oil should be replaced in order to extend
the life of the jack. Use hydraulic jack oil only.
3IMPORTANT: Only fully qualified personnel should attempt
hydraulic maintenance or repair.
4.6. To check the hydraulic oil level, fully lower the jack and the
handle and remove the oil filler plug (fig.2). The correct oil
level should be approximately 5mm below the filler opening.
If oil level is low, fill as required. Make sure that dirt is not
allowed to enter the hydraulic system. Carefully pump unloaded
jack 5 or 6 times to expel any air and then refit oil filler plug.
NOTE: Only use a good quality hydraulic jack oil.
pWARNING: DO NOT use brake fluid, or any fluid other than
hydraulic jack oil, as this may cause serious damage to the
jack and will invalidate the warranty!
