Tightening of Wheels
The nuts should be tightened in a star order and should be tightened to the specified torque.
After driving about 100M and before placing them under load, re-tighten nuts to specified torque.
Check wheels and nuts after operating sprayer for 3 hours and again after 10 hours.
Check wheels and nuts frequently and keep them tight.
Torque of wheel nuts :
3000L Sprayer with MHP11- Wheel Motors - Studs M20x1.5 - Tightening Torque = 600Nm
3500L Sprayer with MHP11- Wheel Motors - Studs M20x1.5 - Tightening Torque = 600Nm
4000L Sprayer with MS18-P Wheel Motors - Studs M20x1.5 - Tightening Torque = 600Nm
4000L Sprayer with MS18-P with C11-25 Brake Wheel Motors - Studs M22x1.5 - Tightening Torque = 695Nm
4000L Sprayer with MS18-CT Brake (Boosted) Wheel Motors - Studs M22 x 1.5 - Tightening Torque = 695Nm
5500L Sprayer with MS18 & MW24 Wheel Motors - Studs M20x1.5 - Tightening Torque = 600NM
5500L / 6000L MS18 - CT Brake (Boosted) Front & MHP20 Rear - Studs M22 x 1.5 - Tightening Torque =
695Nm
Note: A calibrated torque wrench and pressure gauge is needed to ensure safe operation and optimum
vehicle performance.
Pressures
Pressures should be check once a week, but where large temperature changes occur with operations at low
pressure – a daily check is advised.
Effects on pressure change by ambient temperature;
For example
A tyre set at 15PSI at 15°C reduces in pressure to 13.4° at 0°C - a 10% drop in inflation pressure
Pressure – CAUTION! The pressurised air in the tyre is dangerous. Explosive separation of a tire and rim
parts can cause serious injury or death. Do not attempt to mount a tire without the proper equipment and
experience to perform the job.
Always maintain the correct tire pressure. Do not inflate the tires above the recommended pressure. Never
weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire
explosion. Welding can structurally weaken or deform the wheel.
When inflating tyres, use a clip-on chuck and extension hose long enough to allow you to stand to one side
and NOT in front of or over the tyre assembly.
TYRES - MAINTENANCE & CARE
Check tyres for cuts, bubbles or other damage weekly. Also inspect wheels for deformation/damage.
An expert should always be called in to make a qualified judgement on the tyres and to carry out repairs.
Tyres age as a result of physical and chemical processes and this may impair their performance. Premature
aging can be caused by sunlight, chemical contact and running under-inflated.
