7.5 Replacing the filter pad of the sniffer tip
(for SL3000XL only)
When you want to change the filter pad, which is placed between sniffer tip and the
handle, you have to take off the sniffer tip first:
1 Loosen the cap nut by turning it to the left.
Notice If the screw is too tight you may use a screw wrench (SW21):
or: Place a screw wrench at the recess of the cap nut and loosen the nut carefully by
turning the wrench to the left.
Notice Don’t use the blue paper pads between each filter pad.
2 Remove filter pad.
