Precautions Concerning Technopolymers And Elastomers; Precautions To Be Taken When Inflating The Tyres - Komatsu WB93S-5 F50003 Operation & Maintenance Manual

PRECAUTIONS TO BE TAKEN DURING MAINTENANCE
2.8.21 PRECAUTIONS CONCERNING TECHNOPOLYMERS AND
ELASTOMERS
Some components of the machine contain polymers and elastomers (Viton sealing rings, Teflon rings,
q
piston seals made of fluoroelastomers, electric cable insulating materials, etc.).
At room temperature and up to approximately 200°C these materials can be handled without taking any
precautions, since they are completely inert.
However, if these materials are burnt, they release highly toxic gases.
Once these materials have cooled down, they must be collected in tight bags, using heavy waterproof
gloves; gloves and materials must be disposed of in a differentiated manner in compliance with the laws
in force.
The contaminated part of the machine must be washed with highly alkaline detergents and then with a
solution made of detergent and water.
Avoid burning seals, electric cables, sealing rings.
q
Dispose of elastomeric and polymeric waste according to the
q
regulations in force.
Do not touch any burnt elastomeric or polymeric waste and in
q
case of accidental burning avoid inhaling the toxic gases
produced.
In case of contact with the skin, immediately rinse with a
q
solution made of water and an alkaline detergent for about 30
minutes and then contact a poisoning treatment center without
delay.
2.8.22 PRECAUTIONS TO BE TAKEN WHEN
INFLATING THE TYRES
Always bear in mind that tyres can burst while being inflated,
q
causing serious accidents.
Before inflating the tyres, always check the wheel rims and the
q
tyre sidewalls and tread for dents, cuts, broken plies or other
defects.
Have the tyres checked and serviced by specialized personnel.
q
Inflate the tyres using a protection structure and a pneumatic
q
inflating gun with extension complete with pressure gauge.
Make sure that there is nobody in the vicinity before starting to
q
inflate a tyre. Stand beside the tyre to inflate it.
Do not exceed the inflation pressures prescribed for the single
q
types of tyre and make sure that all the tyres have the same
pressure.
