5. Before use
5.1 Inspection before use
Each time before starting work check that:
• All components are in good condition with no visible damage (Iike holes,
tears etc.). Replace any damaged or worn parts. Carefully examine the
air hose, seals and the face piece.
• There is a good connection between the air hose and the headpiece as
well as the blower unit.
• There is sufficient air flow (see 5.2).
• The air is supplied through the whole respiratory system from the blo-
wer to the hood.
• Check the battery before the first use (see 5.3).
5.2 Air Flow Test
1. Disconnect the air hose fram the Blower unit.
2. Insert the Airflow indicator into the air hose connector and keep the
hose in vertical position at about the eye level.
3. Switch the power unit on. The airflow is sufficient only if the ball indi-
cator reaches the minimum flow rate level. If the indicator is below the
minimum flow rate level, it is necessary to charge the battery or change
the filter. If the problem still persists, see chapter 8 for additional sugge-
stions.
5.3 Batteries
The removable rechargeable battery used is a Lithium Ion cell. When
supplied the battery may hoId a small charge, the unit should be run flat
and then charged for sixteen hours before the first use.
NOTE! Batteries are delivered only partially charged. All batteries must be
charged before they are used for the first time. The battery can be charged
separately or on the blower unit.
The charger must not be used for any other purpose than that for which
it was manufactured. Do not charge the battery in a potentially explosive
atmosphere. The battery charger is intended for indoor use. It must be
protected against damp. The charger controls the charging automatically.
After the battery has been charged, the charger switches to the trickle
charging regime and keeps the battery fully charged. The charging time is
6 to 8 hours.
