1. MAINTAINING AND CHECKING THE MECHANISM
NOTE: OIL AND GREASE
• Always use the specified brands of oil and grease. If you
use a grease with the wrong viscosity, for example, this
can lead to all sorts of problems. Be careful to keep the
oil and grease free of dust and foreign bodies.
• A “drop” of oil is the amount of oil remaining on the tip of
a rod with a diameter of 1.5mm after it is dipped in oil to
a depth of 1cm and then taken out.
