First Green Industries MiniZ400 Instructions D'utilisation Et D'entretien page 13

$ While the boom is raised and not secured, any maintenance of the hydraulic system and any maintenance works
under it are prohibited. During maintenance and repairs, it is necessary to secure the raised boom in its position
with the safety strut that forms part of it.
$ Any interventions during maintenance of the hydraulic transmission may only be carried out with the engine stopped, when
there is zero pressure in pipes and hoses.
$ After an attachment has been mounted, its operation needs to be checked without a load.
$ It is not allowed to use any lubricants other than those specified in this maintenance manual. Mixing individual lubricants
is prohibited.
$ Contact an authorized service centre to have more complex repairs carried out by them.
Danger
When working on a slope, there is a risk of the loader tipping over.
6.10 SECURITY RULES FOR TRAVELLING ON PUBLIC ROADS
$ Moving on public roads is prohibited.
$ When driving, the boom must be fully lowered to the lowest position, with the bucket tilted towards the boom to the
maximum extent possible, and with the cutting edge of the bucket covered with a protective cap.
6.11 LOADING, CLAMPING WHEN LOADING
For moving the loader with a crane, use a lifting device with a load capacity of at least 1.5 tons. A steel rope or a textile belt
with a load capacity of at least 1.5 tons can be used for binding. The attachment points are located at the front on the boom
arms and at the rear on the inside of the cross-member of the frame, and are marked with the "HOOK" symbol.

Caution
When loading, the boom must be locked in the lower position!
6.12 IT IS PROHIBITED:
$ to use the loader without training and without following the operating manual;
$ to leave the loader with the engine running or the boom raised; when parking, the boom must be lowered all the
way down and the bucket be resting on the ground;
$ to exceed the loader's carrying capacity;
$ to let persons into the loader's work zone and to transport persons with the loader;
$ to use the loader for any work other than specified in the operating manual;
$ to otherwise modify attachments and use any equipment other than specified by the manufacturer for the approved
version of the loader;
$ to turn with and drive the loader with the boom raised and the bucket filled.
Danger
Before putting the machine into operation, the operating personnel must receive the respective instruction!
Untrained operating personnel may cause injury or death.
There is a risk of falling when working on high parts of the loader.
7. TECHNICAL DESCRIPTION
The MiniZ 400 universal front loader is suitable for loading, sweeping and moving rocks in Classes 1 to 4 using the basic
shovel, and for pulling rocks, digging narrow grooves and drilling pits in rocks in Classes 1 and 2 according to ČSN 733050,
using specifically designated attachments. An extract from the ČSN 733050 standard can be found on page 73 of this
operating manual.
The loader is driven by electrical units. The transmission mechanism consists of two separate gearboxes and two crawler
undercarriages.
The loader control and control of the work device is channelled into two control levers, which control all the operating
functions.
The turning of the loader is facilitated by the different revolution speeds of the individual tracks. The basic shovel is
toothless. In addition to the basic shovel, other attachments can be mounted on the machine as well using quick clamps.
The following sections of this operating and maintenance manual provide instructions for controlling, using and maintaining
the loader. You must familiarize yourself with the content of these instructions before starting any work.
In the basic version, the loader can work in the WT climate zone according to ČSN 038900, with the range of working
temperatures adjusted to -15 to + 35 °C according to ČSN ISO 7131 (Earth-moving machines – Loaders). For working in other
climate zones, the loader must be modified in a manner that is subject to arrangement with the manufacturer.
7.1 LAYOUT OF AGGREGATES
The frame (1) of the loader carries the aggregates, which are concentrated in larger assembly units. The batteries (2) are
stored in a section of the frame. Hydraulic tank (3) and hydraulic distributor (5). Electric motors with a gearbox (7) for travel
are located in the rear part of the frame. Tilting platform to stand on (12).
The work device (9) on which the work tool (10) is mounted is attached to the rear part of the frame. The track chassis (8)
is attached to the bottom part of the frame. In the front part of the frame there is an electric motor with a gear pump (4).
The hydraulic oil is filtered through a filter (6). In the rear upper part of the frame there is a space for storing the remote
control (11).

7.2 ELECTRIC MOTOR
The loader is driven by two three-phase electric motors with a total output of 2 x 2.7 kW.

7.3 HYDRAULIC SYSTEM
The loader's hydraulic system is used to control the work device. The system consists of an electric motor, hydraulic pump
and distributor.
The entire hydraulic system is protected by relief valves. Pressure adjustment on the relief valves during the warranty
period may only be performed by a service technician, and after the warranty period by a trained worker. For attachments,
connections with quick couplings are routed via the boom to its front part.
7.4 BRAKE SYSTEM
The service and parking brakes are activated via controls (by setting these to the neutral position).
7.5 WORK DEVICE
The work device consists of a boom, clamp and hydraulic cylinders.
It is pivotally attached via pins to the rear of the frame. The basic work tool is mounted on the front part of the boom using
the clamp. The boom is raised and lowered by a pair of hydraulic cylinders.
Another pair of hydraulic cylinders ensures the picking up and dumping of soil from the work tool (bucket).
7.6 CLAMPING ON ATTACHMENT
7.6.1 THE "MINIZ" QUICK CLAMP
1. Before clamping, the clamping surfaces on the attachment and on the quick clamp must be cleaned of any dirt.
2. The attachment to be clamped on must be placed with the bottom and the cutting edge on the ground so that the
cutting edge faces away from the machine.
3. By flipping the lever (position 1 in Figure 6: Released quick clamp) into a vertical position, insert the quick clamp by
its pins (2).
4. By handling the loader and the quick clamp, fit the clamping pins (3) of the quick coupler into the beds on the
attachment.
5. Adjust the attachment by tilting the quick clamp so that the holes on the work tool are opposite the pins (2) on the
quick clamp.
6. Secure the attachment by sliding the pins (2) out and into the hole on the work tool, and flip the levers (1) back to their
original (horizontal) position (Figure 7: Quick clamp in secured position).
