TROLLEY JACK 2T

MAINTENANCE

• When the vehicle jack is not in use, the lifting arm must be in the lowest position and the handle in

a vertical position so as not to interfere.

• The jack must be stored in a horizontal position and in a dry place. Make sure that the jack remains

in its original condition. Do not make any modiﬁ cations to the appliance.

• Only use special quality hydraulic oil for the pump. Properly dispose of any old or spilled oil.

• Do not use a high-pressure cleaner to clean the jack. All external moving parts, e.g. bearings (5),

lift arm ﬁ xing bolts (6), lift arm cylinder ﬁ xing bolts (7) and pump arm ﬁ xing bolts (8) must be

lubricated regularly every 3 months.

IMPORTANT: Never lubricate or grease the rods of the pump (9) and the lift cylinder (10).

• All maintenance and repair work must be carried out by suitably qualiﬁ ed personnel in accordance

with the manufacturer's instructions.

• Caution: Do not use the jack if any parts are missing, loose or broken (risk of accident!).

NOTE: The instructions below should not be carried out when the jack is in use.

NOTE: The vehicle jack is equipped with a safety valve (15). It has been conﬁ gured to allow the jack

to lift loads up to 2 tons. The safety valve must not be altered or adjusted in any way!

Problem 1: The lifting arm does not lift when pumping under load

- Check that the drain valve is completely closed. Close it by turning the handle clockwise.

- Check the oil level by placing the vehicle jack in the horizontal position.

- There is not enough oil. Top up the hydraulic oil and bleed the hydraulic system.

Problem 2: The lift arm sinks under the load

- Follow the instructions provided for "Problem 1". If this does not eliminate the fault, the vehicle

jack must be repaired by an authorised repairer.

Problem 3: The lift arm cannot be lowered

- The lift arm tension spring has come loose or broken. Unhook the spring or replace the broken

spring with a new equivalent spring.

- The vehicle jack probably needs to be lubricated. All moving parts should be cleaned and

lubricated or greased. IMPORTANT: The rods of the pumping and lifting cylinder must never be

lubricated or greased.

- Too much oil in the hydraulic system. Unscrew the drain valve and drain oﬀ the excess oil.
