Applying Grease to the Grease Fittings (continued)
4
Refer to the removal steps in the previous
procedures to remove the X, Y, or Zaxis
covers. If applicable, remove the four screws
that secure the fixture plate and remove it.
As you remove each cover (and the fixture
plate, if applicable), use the syringe to apply the
grease to the grease fitting of each linear guide
slider, located as follows:
• Xaxis linear guideway grease fitting —
behind the sliding panel.
• Yaxis linear guideway grease fitting —
below the sliding panel.
• Zaxis linear guideway grease fitting —
behind the ball screw.
NOTE: There are no Zaxis linear guideway
fittings in R / RV Series units.

Component Replacement
This section provides replacement procedures for the robot timing belt, motor, and fuse. These components do not
have a replacement schedule and only require replacement in the unlikely event of damage or breakage.

Timing Belt Tension Adjustment
The X and Yaxis timing belts require a specific tension, which is measured using a belt tension meter. The meter
works by analyzing the harmonic characteristics of a vibrating belt. Use of the tension meter requires the input of
the belt mass, belt width, and span length; these values are provided on page16. Perform the following steps
whenever you need to adjust the tension for a timing belt.
NOTE: This procedure is repeated where applicable in the component replacement procedures.
1. Enter the timing belt mass, width, and span (length) into the tension meter. Refer to “Timing Belt Mass, Width,
and Span Data” on page16 for these values.
2. Hold the meter 20 mm (0.8") from the timing belt, then strum the belt (as if it were a guitar string).
3. Observe the measurement displayed on the meter:
• If the tension is within 50–70 N•m (37–52ft‑lb), the tension is correct
• If the tension is outside 50–70 N•m (37–52ft‑lb), adjust the timing belt adjusting kit base screw and repeat
the tension measurement. Repeat as needed until the tension measures 50–70 N•m (37–52ft‑lb).
NOTE: The tension meter displays measurements only as Newtons.
