Please read these precautions thoroughly before you perform the gas inspection, or
discharge of the gas, i.e. filling.
WARNING!
Risk of accident and injury when extending or shortening the compensating cylinder.
Risk of suffocation with insufficient ventilation
Before you carry out the gas inspection or discharge of the gas, i.e. filling, check that the
brake of the L-axis motor is working properly and that the L-axis is securely locked.
 The compensating cylinder is nitrogen filled.
 Feed no other gas than nitrogen into the balancer unit.
 When working with nitrogen, the possibility of suffocation exists. Therefore, adequate
ventilation is required during work.
 Before you carry out the gas pressure inspection of the balancer unit or discharge of
the gas, i.e. filling, check that the brake of the L-axis motor is working properly and that
the L-axis is securely locked so that it cannot move. Non-observance can lead to very
dangerous situations by loosening the brake of the L-axis motor. Because the L-axis
causes the rotating of the arm without retaining force.
 When dealing with nitrogen, sufficient caution, as well as compliance with the applicable
laws and regulations of local authorities are required.
 For gas filling devices, contact your YASKAWA service representative.
NOTICE
To maintain the sealing performance, small quantity of oil used may leak from the bottom
part of the gas balancer.
