Economical model with low power consumption
With the adoption of a energy-saving compact motor,
electric power consumption has been lowered by more
than 35% compared with the conventional model, while
enhancing productivity with the improved max. sewing
speed. The RH-9820 is the most energy-saving electronic
eyelet buttonhole sewing machine in the market.
Semi-submerged installation is available
By using the optional parts for semi-sub-
merged installation, favorable operation
style can be selected.
Easy adjustment favorable to maintenance staffs
While continuing the conventional basic adjusting method, many improvements have been made.
Installation to production lines and fine adjustment of the machine can be done in a shorter time.
• The number of air tubes has been reduced, saving the trouble of connecting.
• Adjustment of the needle bar and the loopers can be made with the familiar, conventional method.
• An eccentric pin is adopted for the spreader. It enables adjustment without steps, making the operation
easier.
Durability of the machine has been improved
The rigidity of the machine arm has been enhanced. Nicking of the knife is substantially reduced by
minimizing lateral movement of the hammer against the knife.
Easy maintenance
Daily cleaning and lubrication can efficiently be done in a shorter time.
Centralized lubrication system

The machine is equipped with a
special pocket in which thread
waste can gather. This prevents
thread waste from littering, keeping
the working environment clean.

rated into one. Minimum oil is automatically
lubricated with wicks from the oil tank to every
parts requiring lubrication, such as the areas
of the needle bar
and looper base.
