Important information:

WARNING

This jack is a lifting device designed ONLY for lifting part of the total

vehicle(i.e. one wheel). Do not move or dolly the vehicle while it is on the jack.

Positon this jack to ONLY lift on the areas of the vehicle as specified by the

vehicle manufacturer.

After lifting the vehicle, ALWAYS support the load with appropriately rated

vehicle support stands BEFORE working on the vehicle.

Do not overload this jack beyond its rated capacity. Overloading can cause

damage to or failure of the jack.

This jack is designed ONLY for use on hard level surfaces capable of

sustaining the load. Use on other than hard level surfaces can result in jack

instability and possible loss of load.

Center load on jack saddle BEFORE lifting vehicle. Off-center loads and

loads lifted when the jack is not level can cause loss of load or damage to the

jack.

Study, understand and follow all instruction in this manual BEFORE

operating the jack.

Failure to heed these warnings may result in collapse of load or damage to

the jack and/or jack failure resulting in personal injury or property damage.

No alterations may be made to the product.

Any discrepancies in regards to machine maintenance and repair work are to

be carried out according to the instructions outlined below and exclusively by

skilled personnel.

Never use speedy lift device to raise load.

When lifting vehicles the wheels still in contact with the hard standing should

always be “choked”. Do not rely on the hand brake to stop the vehicle from

rolling.

Operating principles

With release valve CLOSED

An upward stroke of the jack handle draws oil from the reservoir tank into the

plunger cavity. Hydraulic pressure holds the valve closed, which keep the oil in

the plunger cavity.

A downward stroke of the jack handles release oil into the cylinder, which forces

the ram out. This raises the saddle (NOTE: Raises if the load exceeds the rated

capacity oil is automatically released back into the reservoir through the safety

overload valve).

When the ram reaches maximum extension, oil is bypassed back into the reservoir

to prevent an overextended ram stroke and possible damage to the jack.

Opening the release valve allows oil to flow back into the reservoir. This releases

hydraulic pressure on the ram, which results in lowering the saddle.

Operating instructions:

1. Assemble handle, front section to larger section using pin provided.

2. When this jack leaves the factory for shipment, the vent plug on top of the oil

chamber is closed to prevent the oil from being spilled. Also the oil chamber

contains the ring amount of oil before shipment. If oil spill is evident, or if vent

plug was found open, it is necessary to check oil level before pumping.

3. Open the release valve and pump the handle 6 full stokes to assure complete

distribution of oil.

4. Close the release valve by turning the handle clockwise, and the jack is ready to

use.

5. Block the vehicle’s wheels for lifting stability.

6. Refer to the vehicle manufacturer owner’s manual to locate approved lifting

points on the vehicle. Position jack so that the saddle is centered under the load at

an appropriate lift point.

7. Pump jack handle to speedy lift level until saddle NEARS contact with the vehicle.

Check to see that the saddle is centered and will contact the load lifting point

firmly.

Always center the load on saddle of jack, Off-center loads and loads lifted while

jack is not sitting level may damage the jack.

8. Continue to pump the jack handle to lift the vehicle to the desired height. After

lifting, support the load with appropriately rated vehicle support stands BEFORE

working on the vehicle.

9. No person should remain in a vehicle that is being jacked.

Figure 1

Care and maintenance:

1. when the floor jack is not in use or in storage the lifting arm and pump lever must

be in the fully lowered position. This will protect the precision machined surface

of the ram piston from corrosion and damage.

2. keep your jack clean and lubricate, as well as the outside parts see figure 1.

3. If spare parts are required these can be obtained from you local service centre.

Ensure to quote the correct serial No. and part No.

4. Be carefully not to spill any oil. If oil is spilled, take care to clean up immediately.

5. As needed, fill the container with specifically blended hydraulic jack oil.

Important note: When adding or replacing oil, ALWAYS use good grade

hydraulic jack oil. Do NOT use hydraulic brake fluid, Alcohol, Glycerin,

Detergent motor oil or dirty oil. Use of an improper fluid can cause serious

internal damage to your jack.

Safe transport of the jack

If you have to move the jack from one place to another, you may use the 2 carrying

handles A og B, see figure 2.

Be aware of correct lifting technique.

Trouble shooting

I. If the jack will not raise, or lift the load.

1) The release valve may not tightly closed. To close or tighten, turn the release

valve clockwise.

2) May air is in hydraulic system. To release air from system.

3) May oil level is low or over-filled in jack. Check the oil lever of the floor jack in

the following manner:

Place jack on level position, open release valve. Correct oil level is bottom of

thread inside oil chamber when lifting arm is at full down position. If tacking oil,

remove vent plug located under cover plate. Fill with oil to correct level and

tighten plug. Close the release valve and pull lifting arm up to its full height. Then

open the release valve and, by stepping on saddle, force it to lower as rapidly as

possible. Repeat this operation three to four times. This procedure will thoroughly

flush the valves and assure-complete distribution of oil. In most cases it will

restore the jack to proper working order. Close release valve tightly. Try jack

under load. The jack may have air trapped in system. Open release valve. Pump

handle 6 full strokes. Close release valve and try jack again.

4) Cup seal for pump may be worn. This will happen only after months of service. A

new cup seal or a complete new piston can be purchased and easily installed.

5) Release valve may be held by dirt on seat.. Flush by pulling lifting arm up and

down several times while release valve is open. If necessary, the release valve

may be removed for cleaning the valve and the valve seat.

6) Power unit is malfunctioning. To replace the power unit.

II. If the jack will lift the load, but will not hold.

1) Oil level may be low in jack, to add oil as required.

2) Power unit is malfunctioning. To replace the power unit.

III.If the jack will not lowered completely, when raised.

1) Return spring for lifting arm may be broken or unhooked. Replace return spring.

2) It probably needs lubrication.

3) Clean and oil all moving in the lifting arm mechanism.

4) Hydraulic unit may contain too much oil and vent valve may be closed.

5) Check level of oil.

IV. If poor jack lifting, pump feels spongy.

1) May air is in hydraulic system. To release air from system.

2) Oil level may be low in jack, to add oil as required.

3) Power unit is malfunctioning. To replace the power unit.

V. If the jack will not lift to full height.

1) May air is in hydraulic system. To release air from system.

2) Oil level may be low in jack, to add oil as required.

VI. If the handle raises by itself when the jack is under load.

1) May air is in hydraulic system. To release air from system.

VII.If jack will not lift full 3ton capacity.

1) The cup seal for piston pump may be worn.

2) The unit may have air trapped in the system.

3) The overload valve is factory adjusted for the pack to lift 3tons load and should

not be altered. Examine jack for binding, causing loss of load.

Should the fault still exist contact your local service centre.

Vigtige oplysninger:

ADVARSEL

Denne donkraft er UDELUKKENDE beregnet til at løfte en del af bilen (f.eks.

et hjul). Bilen må ikke bevæges eller flyttes med transportruller, mens den står

på donkraften.

Donkraften må KUN løfte de områder af bilen, der er angivet af

bilfabrikanten.

Når bilen er hævet, skal den ALTID understøttes af korrekt udstyr, FØR der

udføres arbejde på den.

Donkraften må ikke belastes ud over sin angivne kapacitet. Overbelastning kan

føre til, at donkraften bliver beskadiget eller svigter.

Donkraften er UDELUKKENDE beregnet til brug på en fast og jævn overflade,

der kan modstå belastningen. Brug af donkraften på en overflade, der ikke er

fast og jævn, kan medføre, at donkraften bliver ustabil og evt. taber lasten.

Lasten skal placeres midt på donkraftsadlen, FØR bilen løftes. En last, der

ikke er placeret i midten, eller løftes, mens donkraften ikke står på en jævn

overflade, kan medføre, at lasten tabes, eller at donkraften beskadiges.

Læs, forstå og følg alle instruktionerne i denne manual, FØR donkraften tages

ibrug.

Manglende overholdelse af disse advarsler kan medføre, at lasten bryder

sammen, eller at donkraften beskadiges og/eller svigter med personskade eller

skade på ejendom til følge.

Der må ikke foretages ændringer på produktet.

Fejl, der medfører vedligeholdelses- og reparationsarbejde, skal udbedres i

henhold til nedenstående instruktioner og udelukkende af uddannet personale.

Anvend aldrig en hurtig løfteanordning til at løfte lasten.

Når der løftes køretøjer, skal de hjul, der stadig er i kontakt med gulvet,

altid ”blokkes”. Det er ikke nok at stole på, at håndbremsen kan forhindre, at

køretøjet ruller.

Driftsprincipper

Med LUKKET udløserventil

Et opadgående pumpeslag med donkraftgrebet fører olie fra beholderen ind i

plungerstemplets hulrum. Hydraulisk tryk holder ventilen lukket, så olien bliver i

plungerstemplets hulrum.

Et nedadgående pumpeslag med donkraftgrebet fører olie ind i cylinderen, så

stemplet tvinges ud. På den måde hæves sadlen (Bemærk: Hæves, hvis belastningen

overstiger den angivne kapacitet, hvorved olie automatisk føres tilbage til

beholderen gennem sikkerhedsventilen for overbelastning).

Når stemplet er ført ud til maksimal stilling, føres olie via et omløb tilbage til

beholderen for at forhindre, at stemplet bliver ført for langt ud, og at donkraften

bliver beskadiget.

Når udløserventilen åbnes, kan olie løbe tilbage til beholderen. Dette udløser det

hydrauliske tryk på stemplet, så sadlen sænkes.

Betjeningsvejledning

1. Greb og frontsektion samles med den store sektion ved hjælp af den medfølgende

stift/bolt med gevind. Det samlede donkraftgreb monteres i donkraftens

grebsokkel ved at presse grebet i bund og efterspænde med låsebolten som er

monteret på siden af grebsoklen.

2. Når donkraften forlader fabrikken for at blive sendt, er ventilationsproppen oven

på oliekammeret lukket, så der ikke spildes olie. Oliekammeret indeholder også

den korrekte mængde olie før afsendelse. Hvis der er spildt olie, eller hvis

ventilationsproppen er åben, skal oliestanden kontrolleres, før der pumpes.

3. Udluftning af det hydrauliske system: Åbn udløserventilen og foretag 6 fulde

pumpeslag med grebet for at sikre, at olien fordeles helt.

4. Luk udløserventilen ved at dreje grebet med uret, hvorefter donkraften er klar til

brug.

5. Blokér bilens hjul for at gøre løftet stabilt.

6. Se brugermanulen fra bilfabrikanten for at finde de godkendte løftepunkter på

bilen. Placér donkraften, så sadlen er centreret under lasten ved et korrekt

løftepunkt.

7. Pump donkraftgrebet hurtigt til løfteniveau, indtil sadlen er TÆT PÅ at være i

kontakt med bilen. Kontrollér, at sadlen er centreret og i god kontakt med lastens

løftepunkt.

Centrér også lasten på donkraftsadlen. Manglende centrering og en last, der løftes

med en donkraft, der ikke er plan, kan medføre beskadigelse af donkraften.

8. Fortsæt med at pumpe med donkraftgrebet for at løfte bilen til den ønskede højde.

Når bilen er hævet, skal den understøttes af korrekt udstyr, FØR der udføres

arbejde på den.

9. Ingen personer må opholde sig i bilen, mens den løftes med donkraften.
