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.
Refilling of oil: Pump and cylinder form a closed sy-
stem and refilling of oil is only necessary in exceptional
cases. To check the oil level it is necessary to take out
the pump, complete:
1. pump the jack half-way up. 2. keep the handle
vertically and block the piston rod (39) in the inmost
position by a screw or the like through the hole in the
re-lease bracket. (47). Mind the inner spring. 3. Re-
move handle and tipping gear as well as two screws
(8) on the top of the lifting frame. 4. Unfasten screw
(30) and disconnect the piston rod and the base
frame by lifting the lifting frame. 5. Lift the loose com-
plete pump up and out of the lifting frame. Correct
oil level is up to lower edge of filling hole (28) kee-
ping the complete pump vertically and the piston rod
pushed in. Too much oil might cause imperfect pump
function.
Oil quantity:
YAK 60/Q: 0.8 l
YAK 50, YAK 60/Q, YAK 100/Q: 1.3 l
Any good hydraulic oil of viscosity of ISO VG15 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 (47) and lever tube. Adjust the
two nuts (11) 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
(31) and change seals in lifting cylinder.
4. The hydraulic unit is leaking: exchange worn seals
with repair kit.
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.
