1) Attach the buffer around the gauge.【Figure1】
※Do not touch on the front face of the gauge so as not to put fingerprints.
2) Fit the mounting rubber inside of the mounting band.【Figure2】
3) Fix the mounting band to the mounting bracket temporarily with the spacer, bolts,
washers, and spring lock washers. Tighten bolts loosely by hands. Do not use a
hexagonal wrench (Allen key) at this stage.【Figure3】
4) Insert the switch unit into the attachment for switch unit.【Figure1】
※If the switch unit is fixed to another place other than the gauge, do not use the at-
tachment for switch unit.
5) Fit the attachment for switch unit and indicator into the mounting band. And then fit
the gauge into the mounting band. Locate the switch unit and the indicator roughly
at this stage. The switch unit and the indicator can be positioned in the range which
they do not touch the mounting bracket and bolts.【Figure4】【Figure5】
※Do not take hands off from the gauge so as the gauge does not fall down.
※If the switch unit is fixed to another place other than the gauge, do not fix/use the
attachment for switch unit to the mounting band.
6) Identify the position of the mounting bracket with the gauge fitted into the mounting
band. Mark the shape of the mounting bracket and the position of the screw holes.
The figure printed on the package can be used to position the screw holes.
※To check that there is enough space for installation, identify the gauge position
with the gauge, switch unit, and indicator fitted into the mounting band.
※When setting the gauge angle, take care not to scratch by hitting the gauge to the
mounting bracket.
7) Disassemble the mounting band from the mounting bracket, and disassemble the
gauge, attachment for switch unit, and indicator from the mounting band.
8)
Attach double sided tapes on the bottom of the mounting bracket.【Figure1】【Figure6】
9) Fix the mounting bracket on the gauge installing position by using the tapping
screws.
10) Fit the attachment for switch unit, indicator, and gauge into the mounting band again.
Take notice that the angle of the switch unit and the indicator cannot be changed
while the bolts are fastened.
※If the switch unit is fixed to another place other than the gauge, do not fix/use the
attachment for switch unit to the mounting band.
11) Attach the double sided tape on the back side of the gauge.
【Figure1】【Figure6】
12) Pass the indicator wire and switch unit wire through the holes of the back case from
the outside. Connect the indicator wire to the connector on the gauge. Refer to part
names section.【Figure7】
13) Put the back case on the gauge. Position the hole for the power supply & tachometer signal wire to the gauge connector for it. Refer to part names section. The indicator wire can be stored in the back space in the back case.
14) Connect the switch unit wire to the connector on the back side of the gauge. The indicator wire can be stored in the storage space in the back case neatly.【Figure8】
15) Connect the power supply & tachometer signal wire to the connector on the back
side of the gauge.【Figure8】
16) Fit the mounting band with the gauge in the mounting bracket by using a spacer,
bolts, washer, and spring lock washer.
※Depending on the installing space, it may difficult to fit the gauge. Do not pull
wires forcefully and take notice not to hit the vehicle by parts.
17) Fasten the bolts with a hexagonal wrench (Allen key) firmly.【Figure9】
18) Fit the regular position bezel onto the gauge with setting the ▼ mark at the position
you like.

STEP４ Final check and setupSTEP４ Final check and setup
1) Make sure the gauge is fixed on the installing position firmly. Then turn the vehicle engine on and off and check the
movement of the pointer, illumination of the gauge, and engine speed signal input.
※Make sure there are no tools on the vehicle floor and that the vehicle surrounding is safe before turning on the engine.
2) Go on to the operation section and set up the number of cylinders, and so on. Give this manual to the customer if
he/she sets up by himself/herself.
