Closed TPS Adjustment
Perform the CLOSED TPS ADJUSTMENT as de-
scribed in THROTTLE POSITION SENSOR (TPS)
in ELECTRONIC MANAGEMENT below.
Injection Oil Pump Cable Adjustment
As oil injection cable is throttle dependent, always
proceed with the oil injection pump cable adjust-
ment after throttle cable adjustment. Refer to LU-
BRICATION SYSTEM.
CAUTION: Improper oil injection pump synchro-
nization with throttle bodies can cause serious
engine damage.
AIR COMPRESSOR
PRESSURE TEST
The pressure test will show the available pressure
from the air compressor.
First ensure there is no leak from compressor gas-
kets, hoses and fittings. Soapy water can be sprayed
on components. Repair any leak.
Disconnect hose outlet from air compressor.
Connect adapters and pressure relief valve to pres-
sure gauge as shown.
1. Pressure gauge (P/N 529 035 709)
2. Adapter for air compressor (P/N 529 035 712)
3. T-adapter (P/N 529 035 710)
4. Pressure relief valve (P/N 529 035 711)
CAUTION: Make sure to install pressure relief
valve to allow excess pressure to escape and to
point valve arrow as shown above. Note the ar-
row on the valve. Otherwise, air compressor
components might be damaged.
Install pressure gauge to air compressor.
NOTE: To prevent fuel from being injected and
from going out the disconnected hose, use the
drowned engine mode to crank engine. While en-
gine is stopped, depress and HOLD the throttle
lever at full throttle position to crank engine.
Ensure the battery is in good condition to get the
normal cranking speed.
Crank engine and observe air pressure.
NOTE: A 1 second beep every second indicates
the drowned mode is active.

WARNING
Be careful with pressure relief valve outlet as
compressed air may flow out from it.
MINIMUM AIR PRESSURE (at cranking)
