WARNING -

Safe usage instructions

1. Study, understand and follow all instructions before

operating this crane.

2. Do not exceed rated capacity.

3. Only use slings and chains with a capacity greater

than the load.

4. Ensure that the load cannot slide or swing during

transport.

5. It is forbidden to stay under a suspended load

6. Legs and extension jib must always be secured

with studs and safety pins.

7. Use only on hard level surface.

8. Lower load to lowest position before transporting.

9. No alterations shall be made to this crane.

10. Failure to follow these warnings may result in per

-sonal injury and/or property damage.

Assembly:

1. Mount fixed wheel (19) with axles and circlips, and

then revolving wheels (21) with screws, washers

and nuts.

2. Raise and mount the mast (3) with screws (22),

washers (12) and two nuts (23).

3. Mount main jib (2) on mast using axle (9) and

circlips (16).

4. Mount the hydraulic unit (6) with axle (5) og circlips

(14).

5. Secure the hydraulic unit with screw (20).

Use:

Lifting:

Activate pump handle using full strokes.

Lowering: Slowly turn the release handle counter

clockwise. The spring in the release handle

causes it to close automatically.

The extension jib can be adjusted to different positions

when removing the spike (7). Remember to secure the

jib again with spike and safety pin.

Maintenance:

Maintenance and repair must always be carried out by

qualified personnel.

Daily: Inspect crane for damage.

Monthly: Grease pump piston thrust pad, and oil

handle axle and main jib axle. Also inspect the crane

for unusual wear and tear.

Oil refill: Refill through the filling hole in the cylinder

using an oil can. Correct oil level is up to lower edge

of filling hole (28) with the jib fully down. Too much oil

causes poor pumping.

Quantity of oil WN11, WN15: 0.8 l.

Quantity of oil WN20, WN25: 2 l.

Any good hydraulic oil of viscosity ISO VG 15 can be used.

NEVER USE BRAKE FLUID!

Safety Inspection:

In accordance with national legislation – minimum

once a year though – the crane must be inspected by

a professional: damages, wear and tear, safety catch

on the hook, adjustment of the safety valve, hydraulic

unit for leakages. Furthermore that all safety labels are

legible.

Trouble shooting:

1. The crane does not lift to maximum position but the

pump retains pressure: refill with oil.

2. Poor pumping (half strokes): vacuum in the reser

voir. Loosen the filling plug (28) and verify oil level.

3. The load is dropping: verify release handle is

closed and release spring (dead man's control) is

properly adjusted. Pre-tension of spring (40/38) is

max. half a turn. If this is not the cause, then the

pump needs repair (worn seals or valves).

Spare parts:

Replace worn or broken parts with original spare parts

only. All major parts may not be available after disconti-

nuation of a model.

Destruction:

Oil must be drained off and legally disposed of.
