Instructions for use:
1. A 11.5-14V DC power supply is required.
2. The red terminal is positive (battery +) and black terminal is negative (battery -).
Be sure to connect them correctly. Otherwise, the fan will not work, causing damage
to the machine due to too high temperature .
3. The long-time operation is allowed when the fan runs properly and air comes in
from the bottom normally .
4. Connect one end of the high-pressure hose to the air outlet of the machine, and
tighten the relief screw .
5. The piston ring used has an automatic abrasion compensation function . It can
recover sealing capabilit y after short-term preheating process when working each
time. Before operation, the accompanying pressure measuring choke plug can be used
to plug up the air outlet of the high-pressure hose for 1-20MPA test, which can quickly
preheat the machine and find possible abnormal operation of the machine at first
time.
6. It is normal when the beginning operating temperature of the machine quickly
rises by 60℃. It is only necessary to pay attention to keeping a single operation not
more than 30min or 90 ℃ in daily use, so as to avoid long-time load operation from
burning the motor.
7. The maximum pressure of the machine shall not exceed 30MPA. The life will be
linearly reduced if the machine is used with overpressure. With all things considered,
it is suggested that the safe operating pressure be 25MPA.
8. The machine must be started with 0 pressure. Upon completion of air inflation,
immediately unscrew the relief valve to empty the high-pressure hose, to prevent
long-time high temperature and high pressure from causing deformation to the check
valve. Never remove the inflation head by force with pressure not emptied, otherwise,
it will cause female head seal ring flyout and failure.
Notes:
1. Professional personnel must be on duty during use process, because high
pressure is serious. Immediately shut down the machine and unscrew the relief valve
if something is wrong. It is suggested to keep normal 25MPA pressure and lengthen
the machine life maximumlly.
2. The operating pressure shall be between 11.5-14V, a single operation shall
not exceed 30min, and the cylinder temperature shall not exceed 95 ℃ (it may shut
down the machine and start the fan only for cooling).
3. Make sure that the operation shall not exceed 1min when the fan does not
work and the air inlet is kept out. Otherwise, it will cause serious damage.
Longber switch power supply has 2 optional voltage inputs, i.e., AC110V
and AC220V. Select switch to the corresponding voltage.
