• Ensure that only trained staff work with the
instrument.
• Forbid to heat the substances with low- burning
point or easy-volatile（MS-H-S）
Risk of burn!
• Caution when touching the housing parts and
the heating plate. The heating plate can reach
temperatures of 340 ℃.
• Pay attention to the residual heat after switching
off.
Protective ground contact！
