WARNING -

safe usage instructions

  1.

 The use of this jack is limited to the removal,  

   installation, and transportation in the lowest posi- 

   tion, of transmissions and differentials.  It may  

   be used - WITHIN THE WEIGHT LIMITATIONS  

   SPECIFIED - with appropriate adaptors manufac- 

   tured especially for the jack to handle other com 

   ponents, such as rear axle units and transfer ca- 

   ses.

  2.

 Be sure that the vehicle is appropriately supported  

   and chocked before starting repairs.

  3.

 Avoid decentral placement of the gravity of the  

   load.  Decentral placement of the load might cause  

   overturning of or damage to the transmission jack.

  4.

 All transportation must take place in the lowest  

   position.

  5.

 Do not overload. Overloading may cause damage  

   to or failure of the jack.

  6.

 This jack is designed for use only on hard level  

   surfaces capable of sustaining the load.  Use on  

   other than hard level surfaces may result in jack  

   instability and possible loss of load.

  7.

 The safety valve being adjusted and sealed by the  

   manufacturer shall not be additionally adjusted.

  8.

 Failure to heed these warnings may result in loss  

   of load, damage to jack, and/or failure resulting in  

   personal or property damage.

Assembling:

1.

  Tighten the legs loosely by means of the 4 bolts 

(49) and the 2 long through-going bolts (55).

2.

  Tighten wheels to legs by means of bolts (47).

3.

  Place jack on level surface to make pump rest on  

the 2 through-going bolts. Tighten the 4 bolts (49)  

before the 2 through-going bolts are tightened.

4.

  Non-observance of this procedure might make the  

jack ”3-legged”.

5.

  Oil pedal, and grease end of pump piston.

Use of Transmission Jack:

Lifting:

   Operate the pedal (14). When the trans- 

mission jack is loaded with more than 120  

kg, the pump will automatically change  

over to high pressure. This will cause trans 

mission jack to rise a little less per stroke.

Lowering: 

Turn release handle (19) slowly to the left.

Maintenance:

Daily: 

Inspect the transmission jack for damage.

Yearly:

 Oil wheel and spike for pedal (17) as well as 

grease end of pump piston (12). The hydraulic system 

is a closed system and demands normally no mainte-

nance.

Oil: 

Correct  oil  level  is  just  below  filler  plug  (53)  with 

transmission jack in its lowest position. 

Quantity of oil:

 3.6 l.

Any good hydraulic oil of viscosity of ISO VG15 can be 

used.

NEVER USE BRAKE FLUID!

Troubleshooting:

1. 

The jack does not lift to maximum height:  Check  

oil   level. - See “Maintenance”

2. 

The jack does not stay in position:  The release  

handle is not properly closed - inspect distortion  

of   spring (20). Tighten loosely release handle  

(19) and dismount it. Place hole on release hand- 

le for screw (48) opposite to hole in valve spindle  

(21); push back release handle with spring enga- 

ged with both cylinder nut (23) and release handle,  

tighten spring max. ½  turn counter-clockwise and  

put on the screw.

Destruction:

When the transmission jack after several years is worn 

out and must be destructed, oil must be drained off and 

legally disposed of.
