ROUTINE MAINTENANCE

Every 3 months, check the integrity of the outside of the extraction arm and clean it with a non-agressive detergent.

Every 12 months:

•Check the flexible hoses and rubber seals for cracks or damage; replace if necessary.

•Check the inside of the extraction arm and clean it thoroughly.

•Check and lubricate the hinge points with lubricating oil. (See Fig. 10 C)

•Check and lubricate the steel cable near the balance wheel with lubricating grease. (See Fig. 10 B)

•Check the steel cables for wear.

•Check and adjust the friction setting of the hood, middle, and base hinges. (See Fig. 10 A, Fig. 11)

•Check the balance construction of the extraction arm. (See Fig. 10 A)

•Check the operation of the airflow throttle valve.
