Accumulator Mechanism

The accumulator functions to compensate against the sudden rise of oil pressure when tightening a hard
joint. Torque scatter and error is minimised.
As the oil temperature increases during consecutive tightening, the accumulator takes in the expanded volume
of oil to maintain a consistent oil volume in the pulse unit. This ensures high tightening torque accuracy.

Environmentally Friendly Design

To reduce effects on the environment and environmental energy
during the life cycle of the tool, no paints is applied to th body of
the tool. Consequently, the effect of paint peeling is eliminated.
The fully cover protector is designed as standard.

Ergonomic Design

Compared with conventional tools, weight is kept to a minimum.
The grip handle size is optimised to provide enhanced levels of
operator comfort. This special grip also absorbs vibration more
effectively.
Furthermore, reduced noise and vibration levels are standard with
the FL series due to the optimised dimensions.

Recommended Torque Range, Max Torque

Shows recommended torque range or max torque of the model. Torque figures in the specifications must be used as guidance only, as final
output depends on type and size of bolts and nuts, joint rate and air pressure etc.
