of the head and position facepiece over the face. Figure 1.
2. Progressively tighten the harness starting with the lower
straps then upper straps (Figure 2). Do not overtighten.
3. Perform a positive and/or negative pressure face fit check.
The Negative Pressure Fit Check is recommended when using
the 3M™ 6035 and 6038 or 2000 Series filters, whereas the
Positive Pressure Fit Check is recommended when using
other 3M filters.
DOFFING
^ Do not remove the face piece, filters or turn off the air
supply until you have vacated the contaminated area.
1. Release the tension on the head straps.
2. Carefully lift face piece off the face and remove the
respirator by lifting up and away from the face.
3. If appropriate, switch off the air supply unit or disconnect the
compressed air supply tube from the regulator, and unbuckle
the waistbelt.
NOTE If the respirator has been used in an area that has
caused it to become contaminated with a substance
requiring special decontamination procedures it should
be placed in a suitable container and sealed until it can be
decontaminated or discarded.

FIT CHECK

• Positive Pressure User Seal Check (for all approved
configurations) (all Filters except 3M™ 6035 /6038/ 2000
Series Filters).
Place palm of hand over exhalation valve cover and exhale
gently. Figure 3.
If the facepiece bulges slightly and no air leaks are detected
between the face and the facepiece, a proper seal has been
obtained.
If an air leak is detected, reposition the respirator on the face
and / or re-adjust the tension of the elastic strap to eliminate
the leakage.
Repeat the above fit check.
• Negative Pressure User Seal Check with 6035 / 6038
Filters Also 2000 Series filters.
Press your thumbs into the central indentation of the filters
(2000 Series), or press filter cover and filter body together
(6035/6038), inhale gently and hold your breath for ten
seconds If the face piece collapses slightly a proper fit has
been achieved. Figure 4. If an air leak is detected, reposition
the respirator on the face and / or re-adjust the tension of the
elastic strap to eliminate the leakage. Repeat the above fit
check.
If you CANNOT achieve a proper fit DO NOT enter the
hazardous area.

MAINTENANCE
Maintenance, servicing and repair must only be carried out by
properly trained personnel. Since this respirator is a low
maintenance face piece only a limited number of replacement
parts are available (See reference leaflet). If other parts are
damaged the respirator must be replaced.
^ Use of unapproved parts or unauthorised modification
could result in danger to life or health and can invalidate
any warranty. General inspection must be carried out before
use or monthly if not in regular use. See Inspection
procedures for specific details. If disposal of parts is required
this should be undertaken in accordance with local health and
safety and environmental regulations.

SPARE PARTS

Replacement parts may be fitted without completely
disassembling the respirator.
Centre Adaptor (6864) Replacement. To remove Centre
Adaptor, remove the nose cup assembly, by pulling the
assembly over the three notches which anchor it to the base of
the centre adaptor.(Fig 5). Grasp centre adaptor at cover and
twist counter-clockwise 1/4 turn to disengage and withdraw
centre adaptor from lens. Replace centre adaptor by pushing
three lugs in through the lens gaps, (Fig6 )and turning it 1/4
clockwise. Replace nose cup assembly.(Fig 7 )
Centre Adaptor Gasket (6896) Replacement. The closed cell
foam rubber centre adaptor gasket is designed to seal the
interface between the centre adaptor and the lens. Remove
nose cup assembly, and center adaptor from lens centre port
as described above. Remove old gasket from centre adaptor
and replace with new replacement gasket. Re-install centre
adaptor into facepiece lens. Replace nose cup assembly. (Figs

Exhalation Valve (7583) Replacement. Remove center adapter
cover by pulling out from bottom latch. Grasp valve and pull
each valve stem out from valve seat. Place exhalation valve
replacement over the exhalation port by inserting stems and

snapped in place. Replace valve cover by aligning top opening
in the valve cover with the top tab on the center adapter base
and snap to the center adapter base. Figure 8.
Inhalation Gaskets (6895) Replacement. The inhalation
gaskets are designed to seal the interface between the
bayonet attachment inhalation ports on the face piece and

integrity is questionable. Remove gaskets from inhalation port
bayonet fittings. Install new gaskets onto face piece inhalation
port under all three bayonet lugs. Figure 9.
Inhalation Valves (6893) Replacement. Inhalation valves are
located on posts at the inside of the face piece inhalation ports
and inside the nose cup inhalation ports. These valves should
be inspected before each respirator use and replaced
whenever valves become damaged or lost. Remove existing
Inhalation valve(s) by lifting from post(s) at the inside of the
face piece and nose cup inhalation port(s). Install new valve(s)
onto post(s). Be certain valve is fully engaged under all three
