a load that is being jacked or is supported only by
a jack.
9.
Only original accessories and spare parts shall be
used.
10.
No alterations shall be made to this jack.
11.
Failure to follow these warnings may result in per-

Assembly
Mount plastic handle on tube lever with inner projec-
tion to fit into slot. Push tube lever into handle until
screw and nut can be mounted (use a rubber hammer
to adjust handle position).
Then place lever in tipping gear, and secure it with tip-
ping gear screw fitting into slot in tube lever.
Use
Lifting:
Activate lever tube up and down using full
strokes.
Lowering:
Pull lever tube up, then slowly turn counter
clockwise.
Maintenance
Maintenance and repair must always be carried out by
qualified personnel.
Daily:
Inspect jack for damages.
Monthly:
Lubricate all mechanical parts with a few
drops of oil.
Oil refill:
Pump with cylinder is a closed system and
refilling of oil is normally not necessary. In order to refill
oil it is necessary to demount the hydraulic unit:
GB
1.
Unfasten screw (23) through hole in base frame.
2.
Release and lower the jack completely.
3.
Keep lever vertically and block piston rod (34) in the
inmost position by means of a screw or nail through
hole in release bracket (42). Mind the inner spring!
4.
Remove lever tube and tipping gear as well as the
two screws (6) on top of lifting frame.
5.
Now the hydraulic unit is loose and can be removed
up front from the lifting frame.
6.
Assembly takes place in reverse order. Pump the
jack half-way up in order to ease mounting of the
last screw (23).
Correct oil level is up to lower edge of filling hole (27)
with the cylinder vertical and the piston rod pushed
completely in. Too much oil causes poor pumping.
Quantity of oil:
DK20, DK20Q and DK13HLQ:
0,3 l.
DK20HLQ:
0,5 l.
Any good hydraulic oil of viscosity ISO VG 15 can be
used.
Never use brake fluid!
Safety Inspection
According to national legislation - minimum once a
year though - the jack must be inspected by a profes-
sional: damages, wear and tear, adjustment of the
safety valve, hydraulic unit for leakages.
Possible faults and how to overcome them
1.
The load is dropping occasionally: Verify the play
between release bracket (42) and lever tube. Adjust
the two nuts (10) until the play is 1-2 mm, irrespec-
tive of the lever tube position (vertical or horizontal).
2.
The jack does not lift to maximum position: refill
with oil.
3.
The load is dropping: leaking pump valves or worn
seals. Inspect the valve seats + balls under plug
(30) and change seals in lifting cylinder.
4.
The hydraulic unit is leaking: exchange worn seals
with repair kit 0906000.
Spare parts
Replace worn or broken parts with genuine jack manu-
facturer supplied parts only. All major parts may not be
provided after discontinuation of a model.
Destruction
Oil must be drained off and legally disposed of.
