CAUTION:

If metal fuel pipe is laid-out, be sure to clear away scraps or chips from the pipe

which are produced during cutting or assembling. Leaving these scraps in the pipe

may cause problem in the fuel pump.

REMOVING AIR TRAP

When operating for the first time or when refueling an empty tank, air may be trapped in the

fuel line, making ignition difficult. In this situation, follow the procedure below:

1. Press “POWER SWITCH” to “OFF” position. Disconnect

the power supply cord.

2. To catch the fuel which will drain out, put a small

container under the strainer.

3. Loosen the screw on top of the strainer. Immediately wipe

off any spilled fuel.

4. Remove the trapped air thoroughly. Failure to remove all

the air will cause improper ignition and may extinguish

the unit.

5. Tighten the screw after removing trapped air.

6. Plug into the receptacle. Press “POWER SWITCH” to

“ON” position.

Note: In the event of an ignition failure, press “POWER

SWITCH” to “OFF” position and after 10 seconds

press “POWER SWITCH” to “ON” position once

again.
