Jacobsen ZA5 Series Safety, Operation And Maintenance Manual page 15

Exposure limits are calculated as a combination of the vibration level (magnitude) of the tool and the
Daily Exposure Time (Trigger Time), e.g. A product with 5m/s² vibration can be used up to 2 hours/day to
Exposure Action Value (EAV) - Daily vibration exposure A(8) = 2.5m/s²
Where daily vibration exposure A(8) is below 2.5m/s² the risk is relatively low and no action need be
Exposure Limit Value (ELV) - Daily Vibration Exposure A(8) = 5.0m/s²
If several tools are use the exposure values must be combined:
Never mow if there is a risk of lightning or you hear thunder. If you are in the middle of mowing,
stop In a safe place, turn off the engine and go inside a building.
When you do any welding on the machine, the battery, controller and display MUST be disconnected

Personal protective equipment (PPE), for example safety glasses, leather work shoes or boots, a hard
hat, leather work gloves and ear protection MUST be used after the owner/user completes a local risk
Training in all manual operations must be given by an approved person before the machine is used the
