Before use and whenever a reduction in air flow is noted, a flow
test using the supplied flow meter is recommended.
1. Disconnect the hose from the air filter unit.
2. Check that the 2 filter cartridges and pre-filter are correctly
fitted (See "Filters").
3. Fit the large end of the flow meter to the outlet of the air filter
unit and hold with the flow meter pointing straight up. Fig 3.
4. Switch on the air filter unit, ensuring that the air entry into the
pre-filter is not restricted (ie. not sitting on a bench), and note
the position of the floating ball in the flow meter. Air flow is
adequate if the ball is within or above the circle. If the ball is
below the circle air flow is insufficient.
NOTE: Full air flow performance may not be achieved until the motor "runs in"
after 1 to 2 hours of operation.
5. If air flow is insufficient possible causes and actions are:
• Discharged batteries – recharge air filter unit.
• Dirty pre-filter – clean or replace the pre-filter (see "Filters").
• Dirty filter cartridges – replace (see "Filters").
Before each use:
• Check the flow rate as specified in "Flow
Testing".
• Check the shroud for correct fitting (See
"Shroud Removal & Fitting". Any small gaps or
openings will reduce respiratory protection.
1. Adjust the helmet headband to suit your head size
using the winder inside the rear of the helmet. Fig.
4. This adjustment is best done while you are
wearing the helmet.The headband should be
comfortable, but firm enough to stop the helmet
from flopping forward.
2. Fit a hose clamp over each end of the hose by
squeezing the clamp fingers together. Connect the
smaller end of the hose to the open end of the
overhead air duct, which exits through the shroud at
the rear of the helmet. Fig. 5a. Relocate the hose
clamp to secure the hose to the air duct. Fig. 5b.
3. Strap the air filter unit to your waist, adjusting the
belt for comfort.
4. Raise the visor and place the helmet on your head
while pulling the earmuffs outward (away from each
other) until they click in the "out" position. Fig. 6.
