in Picture 1 on Page 18. Wipe them with cloth to remove excessive oil.
(3)Inspect the exposed parts of guide rods; keep them clean; remove dirt
and oil stain on the rods with soft cloth. (Note: You can only inspect, clean
and lubricate guide rods after dismantling shrouds.)
(4)Spray silicone oil onto the exposed parts of guide rods or cloth, and
then wipe guide rods with cloth.
Never lubricate the rods when the
machine is in use; the parts which are hidden in weight plates can
only be lubricated after the weight plates are removed, otherwise, it
will cause severe injuries.
Reminder: Do not use petroleum-based lubricant; it will lead to
rapid accumulations of dirt and hair on weight plates and may get the
weight plates stuck to each other.
(5)Inspect and test steel cable and the links thoroughly every week;
inspect cable tension.
(6)Inspect cable connection at weight plates. Make sure that the bolt
makes at least 10 turns (15mm) towards the selector bar. Inspect the
two thin nuts at both ends of the nut and ensure that they are securely
tightened.
(7)Inspect steel cable; pay special attention to parts which are in contact
with pulleys and cams. Inspect links at cams; inspect bolts which pass
through parts on the top of cams and assure that set screws are tightened.
(8)Inspect steel cable; make sure all connections are firm and secure,
tension is appropriate and steel cable is correctly fixed on the top of weight
plate.
(9)Inspect pulleys: check if there’s abrasion, flaw, breach or deletion.
Abrasion of pulley surface can lead to severe damage to steel cable.
Therefore, abraded or damaged pulley must be replaced immediately.
Make sure pulleys can revolve flexibly during usage and do not sway to
left and right with big amplitude. Big amplitude indicates that set bolt or
