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.
