1. SAFETY INSTRUCTIONS
1.1 SAFETY INSTRUCTIONS
— PPE (Personal Protective Equipment) must be worn (please refer to the "PPE table").
— Only control the loader from the control station. Keep controlling until movements stop.
— Do not leave the control station without stopping all control movements (control lever locked).
— Never leave the tractor with the loader lifted. After using the loader, park the tractor with the loader lowered to the ground.
— All persons must be kept away from the area in which the loader is moving while it is in operation. If any lifting operations
require the presence of a person near the load, the MX loader must be tted with a safety device (see the "SAFETY
WHILE LIFTING AND DUMPING" chapter).
— Before use, the operator should be sure that the loader-tractor unit and the implement-loader unit are compatible.
They should refer to the MX price list in force with their dealer.
— The operator must use an implement designed and recommended by MX for the work to be carried out.
— Carrying or lifting persons using the loader is forbidden.
— Ensure tractor stability by using a suitable counterweight (see the "COUNTERWEIGHT" chapter).
— Restrict all movements with the load lifted as he tractor may become unbalanced.
— The maximum front axle loading specied by the tractor manufacturer must not be exceeded.
— In order to limit stresses on the front axle and steering ram, and to limit tyre wear, move forwards or backwards
when steering.
— The maximum loading on the front tyres specied by the tyre manufacturer must not be exceeded.
— Check tyre pressures regularly.
— Check periodically to ensure that safety pins and bolts are in place. Do not replace them with any other items such as:
nails, wire, etc.
— For full use of the MX loader, the tractor must be tted with a falling object protective structure, or at the least
a roll-over protective structure with four uprights. If this is not the case, limit the use of the MX loader
(see the "LOADER USE LIMITS" chapter). Caution: the protective tting must be in active position while working.
— Watch out for overhead electricity and telephone lines, guttering, framework, etc. when moving with the loader
in raised position.
— In compliance with the EN 12525 + A2 2010 standard, the controls for operating the loader and implements must
be "sustained action" type except for the oating position which can be held in place by a notching system.
— Any fault diagnosis and/or removal of parts must be carried out by a professional who shall start by guaranteeing
that the work will be carried out safely for him and his environment, notably in the case of work on a lifted loader.
— For all operations on the machine, pay attention to the risks of crushing or pinching, especially with moving parts.
— For all interventions at height on the machine, use stable and secured means. Stop the tractor engine, if the loader
is hitched to the tractor.
— Keep the tractor-loader clean to avoid the risk of re.
- Ensure that airborne particles (straw, grass, wood shavings, etc.) do not accumulate in areas which reach high
temperatures.
- Inspect and clean sectors where different materials can accumulate, especially around the engine and the exhaust area.

1.2 LOADER USE LIMITS ON A TRACTOR WITH A ROLL CAGE WITH 2 UPRIGHTS
Additional information for a tractor tted with a roll cage with two uprights.
1.2.1 Warning
If the tractor is not tted with a falling object protective structure or a roll-over protective structure with four uprights
(tractor with roll cage with 2 uprights), the driver is exposed to a permanent risk when handling loads.
Reminder: only implements recommended by the MX loader manufacturer may be used.
1.2.2 Usage precautions
For safe work, the following usage precautions must be observed:
— Use the implement designed for the work to be carried out.
— Adjust the indicator rod according to the implement used.
— Ensure the stability and hold of the load in the implement.
— The maximum loading level of the implement must not exceed the lowest side for bulk loads, and not exceed the height
of the backplate for unit loads (see Fig. 1).
— Move the tractor-loader unit carefully.
— Travel with the load at ground level and at moderate speed.
— During a lifting operation and when moving, keep your eyes on the load from when the implement’s pivot point (A)
passes the horizontal of the loader’s pivot point (B) (see Fig. 2). If necessary, correct the position of the implement so
that the load is never directed towards the driver (see Fig. 3).

1.3 NON-COMPLIANCE WITH THE INSTRUCTIONS FOR SAFETY AND USE
— The MX loader’s hydraulic circuit is designed to withstand a maximum service pressure of 200 bar.
— Never make any changes to the hose connections.
— Breaking lead seals will void any liability on the part of MX for all its equipment.
— Any assembly of the MX loader which ignores the recommendations of the MX price list in force at the purchase
date cancels the MX guarantee for the whole supply.
— Any modication to any item supplied by MX (implements, loader, frame, etc.), or installation or use of an implement or
component not recommended by MX on the MX loader, will render the MX guarantee on all supplied items null and void.
— Use only genuine MX spare parts. Do not carry out any modications yourself or have anyone else do so on your
MX loader and its implements (mechanical, electrical, hydraulic or pneumatic specications) without seeking prior
approval in writing from MX. Failure to comply these rules may make your MX loader hazardous. In the event
of damage or injury, MX shall not be held responsible in any way.
— Warranty cover will cease immediately in the event of failure to observe the standards and instructions for use
and maintenance of the MX loader as stipulated in the user manual. MX shall not be held responsible for accidents
that might result from actions contrary to these restrictions.

3. IDENTIFICATION PLATE
The identication plate is located inside the loader’s right arm.
The serial number and loader model shown on this plate must be quoted in any request for spare parts information
or technical assistance.
4. COUNTERWEIGHT
The stability of the tractor-loader unit can only be ensured with a counterweight installed on the rear of the tractor.
This should ensure that 20% of the gross weight (tractor, loader, implement, maximum load and counterweight)
bears on the rear axle of the tractor for optimum working safety.
The formula below is used to calculate the counterweight (M) (standard EN12525 + A2 2010).
G: Load on the rear axle, with no counterweight, with empty implement (kg).
G1: Load on the front axle, with no counterweight, with empty implement (kg).
b: Distance from front axle to the implement’s centre of gravity (mm).
I1: Distance from the linkage arm pin to the rear axle (mm).
I2: Wheelbase (mm).
N: Usable load of the loader for implement pivot point (A) horizontal with the loader pivot point (B) (kg).
P: G + G1 (kg).
M: Counterweight (kg).
