Maintenance and inspection procedures
6) In the RV-13FR series, wind thread sealing tape two or three times around the thread of the screws removed
from waste oil portion (1), (3), and (5) (refer to the image below). Then tighten the screws by 7.1 N·m to 8.5 N·m.
If the screw is tightened with lower/higher torque or not winded a sealing tape, it may cause grease to leak.
(Recommended sealing tape: NITOFLON Pipe Seal No.95 (JIS), manufacture: NITTO DENKO)
7) Remove the grease nipples installed above and install the original screws.
・ RV-4FR/7FR series
Tighten the screws by 4.7N·m - 6.3N·m.
・ RV-13FR series
In lubrication portion of from (7) to (10), tighten the screw by 4.7N·m - 6.3N·m.
In lubrication portion (2), (4), and (6), wind thread sealing tape two or three times around the thread of the
screws (see
). (Recommended sealing tape: NITOFLON Pipe Seal No.95 (JIS), manufacture: NITTO DENKO)
Tighten the screw of lubrication portion (2) to the end surface of grease guide.
Tighten the screw of lubrication portion (4) and (6) by 7.1 N·m to 8.5 N·m.
If the screw is tightened with lower/higher torque or not winded a sealing tape, it may cause grease to leak.
8) Replace the covers with the removal procedure in reverse.
9) If the maintenance forecast function is enable, please reset the accumulated data about grease. Carries out the
resetting operation by RT ToolBox3 (option) or parameter MFGRST. Refer to separate "RT ToolBox3/RT
ToolBox3 mini User's Manual" for the operation method of RT ToolBox3, and refer to separate "Instruction
Manual/Detailed Explanation of Functions and Operations" for details of parameter MFGRST.
Use manual grease gun, and inject grease with pressure 0.03Mpa or less. Do not use
the grease gun, which derived by the factory air presser to avoid injecting by too
high pressure.
A grease gun that fits the grease nipple is required.
Recommended grease gun: KH-120 (amount: 140ml) or KH-32 (amount: 200ml)
(manufacture: Yamada Corporation Inc.,)
The grease guns come with a short nozzle (HSP-1) as standard. If this short nozzle
does not reach the desired areas, depending on the robot model and installation
location, it may be useful to use a long nozzle (HSP-2).
