CHECKING REFRIGERANT
If the refrigerant is insufficient, the
performance of the air conditioner is
deteriorated. Also, charging the air
conditioner with excessive refrigerant
affects its performance. Therefore,
have the system checked by your
local KIOTI Dealer if a malfunction is
found.
1. Operate the air conditioner as fol-
lows.
• Engine rpm: Approx. 1,500 rpm
• Temperature control switch: at the
maximum cooling temperature
point
• Air volume control switch: 4 steps
• Air conditioner switch: “ON”
WARNING
• Only qualified service per-
sonnel should service the air
conditioner as its refrigerant is
under high pressure. An injury
can occur.
CAUTION
• Park tractor on a at place and
chock the wheels.
• Put forward/backward lever,
Main shift lever and PTO lever
