WARNING
The gas spring is charged with high-pressure nitrogen gas, so improper handling may cause an explo-
sion resulting in serious personal injury or death. For this reason, always observe the following precau-
tions.
• Do not disassemble.
• Do not bring an open flame close to it or do not dispose of it in fire.
• Do not perform drilling, welding or flame-cutting.
• Do not hit or roll it, or subject it to any impact.
• When disposing of it, the gas must be released. Ask your Komatsu distributor to have this work per-
formed.
