Gap Adjustment for Head Unit

Mechanical Valve and Plunger

[Gap adjusting procedure]

Loosen the cap screws (4 pcs, C3 x 5).

Adjust the gap between the end of the

retracted plunger and the end of the

projected mechanical valve to 1.5 mm

using a thickness gauge.

The mechanical valve and the plunger head

should be parallel to each other.

While matching the axis center in

height direction, fasten the cap screws

(4 pcs, C3 x 5) to fix the plunger.

HLGB-10411-01

Adjustment of Plunger Upper/Lower

Backward Detect Sensor

Perform this working on both heads on the front side and rear side.

[Necessary jigs]

• Thickness gauge

[Procedure]

Press in the mechanical valve.

Pull out the plunger by hand, and

pinch a thickness gauge of t=1.0 mm

between the plunger and mechanical

valve.

Move the bracket to adjust the sensor

position so that the LED for the

plunger return sensor extinguishes in

this state.

Adjustment of Plunger Upper/Lower

Backward Detect Sensor

Press in the mechanical valve.

Pull out the plunger by hand, and pinch a thickness gauge of t=1.2 mm between the

plunger and the mechanical valve.

Check that the LED for the plunger return sensor lights up in this state.
