Table 5-4 using a grease gun from the lubrication grease nipple.
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)
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).
