Questions about this item

Which heat gun models does the GRD-007 shutter guard fit?

It fits Master Appliance models HG-201A, HG-201AK, HG-201A-MC, HG-301A, HG-301AK, HG-301A-MC, HG-501A, HG-501AK, HG-501A-MC, HG-751B, HG-751BK and HG-751B-MC.

How do I install the shutter guard on the heat gun?

Slide the guard over the nozzle end until it seats against the barrel; the step most people miss is pushing it fully home so the shutter cannot shift during use.

When should the shutter guard be replaced?

Replace it when the shutter blades no longer close cleanly or the guard shows heat distortion that prevents a snug fit on the nozzle.
