Astro Pneumatic 8077SE warranty Assembly & Operation, Adjusting the FIT of the Helmet

8077SE

ASSEMBLY & OPERATION

The helmet comes ready assembled but before it can be used it must be adjusted to fit the user properly and set up for delay time,sensitivity and shade level.

ADJUSTING THE FIT OF THE HELMET

•The overall circumference of the headband can be made larger or smaller by rotating the knob on the back of the headband. (See adjustment "Y" in fig.1) This can be done whilst wearing the helmet and allows just the right tension to be set to keep the helmet firmly on the head without it being too tight.

•If the headband is riding too high or too low on your head adjust the strap which passes over the top of your head. To do this release the end of the band by pushing the locking pip out of the hole in the band. Slide the two portions of the band to a greater or lesser width as required and push the locking pip through the nearest hole (See adjustment "W" in fig.1)

•Test the fit of the headband by lifting up and closing down the helmet a few times while wearing it. If the headband moves while tilting re-adjust it until it is stable.

ADJUSTING DISTANCE BETWEEN HELMET & FACE

•Step 1: Undo the block nut (See "T" in fig.1) to adjust the distance between the helmet and your face in the down position.

•Step 2: loosen the block nut on either side of the helmet and slide it nearer to or further from your face.

(See adjustment "Z" in fig.1) It is important that your eyes are each the same distance from the lens otherwise the darkening effect may appear uneven.

•Step 3: Re-tighten the block nut when adjustment is complete.

ADJUSTING ANGLE OF THE MASK IN THE DOWN POSITION

•If the lens is not properly aligned with the eyes in the down position the mask angle can be further adjusted into one of three preset positions using the tilt plate shown in fig.2. Behind each pivot knob on the sides of the helmet there is a screw which passes through the side of the mask and into one of the holes in the tilt plate ( see A,B,C in fig.2 ).

•Partially undo each screw counterclockwise so that it withdraws out of the tilt plate but remains in the side of the mask. Rotate the assembly so that one of the alternative positions is aligned with the end of the screw. Turn the screws clockwise again so that they pass through the holes thus fixing the position of the tilt plate.

SELECTING SHADE LEVEL

•Select the shade level you require according to the welding process you will use by referring to the "Shade Guide Table" below for settings. Turn the shade control knob on the side of the helmet to the shade number required.

SELECTING DELAY TIME

•When welding ceases the viewing window automatically changes from dark back to light but with a pre-set delay to compensate for any bright afterglow on the workpiece. The delay time/response can be set to "short" to "long" as you require using the dial knob on the back of the shade cartridge. (See fig.3)

SENSITIVITY

•The sensitivity can be set from "high" to "low" using the dial knob on the back of the shade cartridge. The"low" setting is the normal setting for everyday use.

•Where the operation of the mask is disturbed by excess ambient light or another welding machine close by, use the "low" setting. (See fig.3).
