As shown, there are two springs on socket head screws holding the brush assembly against the blade. There is also an
adjusting stop socket set screw A with a hex nut C on it. This adjusting set screw works as a stop determining the brush
position in respect to the blade. To move the brush closer to the blade loosen the hex nut and turn the setscrew A counter
clockwise with an Allen key. Then rotate the brush stem towards the blade and turn the spring loaded socket head bolts
B in to maintain proper spring preload. To move the brush away from the blade loosen the spring loaded socket bolts B
respectively. Then rotate the brush stem away from the blade and turn setscrew A clockwise to lock the brush in position.
Lock the hex nut to prevent the set screw from loosening.
ANGLE BRAKE ADJUSTMENT
The clamping force on the swivel brake can be adjusted to ensure that the Head is held securely and does not move dur-
ing cutting. The brake handle should be adjusted so that it does not “bottom out” or hit its movement limit, yet holds the
head securely.
ANGLE BRAKE ADJUSTMENT PROCEDURE
STEP Loosen locking cap screws “B” with a 6mm Allen key.
STEP 2 Tighten all 4 set screws “A” until snug with a 4mm Allen key
STEP 3 Back out the “A” screws ¼ of a turn
STEP 4 Tighten the locking cap screws “B”
STEP 5 Swing the head to 45° and back to ensure that the head moves freely and does not bind on the pivot surfaces.
Continue to step 6 if necessary.
STEP 6 Adjust the clamping force bolt “C” with a 9mm wrench. If not tightened enough, the locking handle will “bottom
out” and not hold the head firmly
