MUFFLERS
The mufflers on the rod ends of the cylinders should be replaced at any time cylinder
problems are suspected. Removing the muffler and moving the exercise arm through its
range will determine if the muffler is clogged. A clogged muffler will make the motion
spongy or rough. When replacing a muffler, coat the threads with oil, silicon lubricant, or
"WD-40", and reinstall snug but not tight. Mufflers should be replaced every 12 months.
Contact the KEISER Service Department for replacement mufflers.
FASTENERS
NUTS, SCREWS AND SET SCREWS
Tightness of nuts and screws should be checked monthly. Most screws should not be
tightened any more than necessary to keep them from turning freely. Any screws that
need to be torqued are noted in the previous pages.
All screws must use self locking nuts to prevent loosening. Those, which thread into
tapped holes (including set screws), must be retained by a thread locking compound such
as “Loctite
242 (blue)”. Screws, which bear on painted surfaces, will normally have a
washer to protect the surface.
