Pivot Cam Adjustment
Note: This instruction only applies to units with serial numbers
≥
412137. The
cams serve the purpose to eliminate “play” from the arms by their outward
position and by removing clearance between their bearings and the shaft they
rotate on. However, if too much pressure is placed on the bearing, this can affect
the amount of resistance to move the arms.
Tools Required
5/32" hex key
Scratch awl
1. Loosen (don’t remove) (6) screws
on both sides. Lower arms should
have some play in them. 2. Set cams to eliminate “play” from
arms. Insert scratch awl into hole
with slight pressure. While keeping
pressure on awl, tighten screws
with hex key.
NOTE: Cams are set correctly when
“play” is removed from arms, but cam is
not set too tightly, which can increase
arm resistance.
