DIFALCO DESIGN SERVICE AND SUPPORT
IMPORTANT! Keep wiper bands and slots free of any dirt with lighter fluid! Lubricate wiper bands with very small amount of braid juice, work trigger back and forth a few times and wipe off excess with towel. Never use sandpaper on PCB! You may flip sandpaper (wet/dry-250 grit or finer) over to smooth out wiper button only if needed! Blow off sandpaper dust to avoid scratching PCB. Oilites need to be oiled only twice a year at the most! Every other month you should remove handle to clean brake contact surfaces on trigger and frame with sandpaper to remove arcing. Also check power contact surfaces for arcing and look for frayed trigger shunt braid while you have controller open.
