2.6.1 

Mandatory Guards 

 

The General arrangement figure found in Section 1.2 and the list below show the mandatory guards required.  
These along with the danger decals and warning decals are necessary for safe cutting operations with this 
machine;

PTO shaft guard 

 

Front metal chain guards 

 

Rear metal chain guards 

 

 

2.7 

Sound 

 
The air noise level created by the machine under operating conditions was detected using a sound level meter 
with integrator. 
 
The measurements were carried out in accordance with ISO 1680-2 with the machine.  
Tests performed under the conditions indicated by the standard produced the following results: 
 

Machine 

Tractor With Open Cab 

Tractor With Closed Cab 

Multicut 300 

94 dB 

80 dB 

Table 2.4 

– Multicut Sound Readings 

 
 

2.8 

Personal Protective Equipment 

 
Operators should be wearing sufficient personal protection 
equipment (PPE) to protect them from hearing, respiratory and 
impact damages. 
 
When working in an unsealed cab or where windows and apertures 
are open to the environment, operators are advised to wear suitable 
eye and ear protection, a facemask (depending on conditions) and 
eye protection. 
 
When handling cutting surfaces or hydraulic equipment, operators 
are advised to wear suitable gloves. 
 
When clearing blockages, clearing wire, or working with pressurised 
hydraulic components, operators are advised to wear suitable eye 
protection and suitable gloves. 
 
Ensure that non-baggy clothing is worn to reduce the chance of 
entanglement and snagging on components. 

Figure 2.4- PPE Items 

 

When working at the work site, but off the tractor unit, operators are advised to wear a ‘high-viz’ garment.
