How to attach with spring washers
• The spring washers that our supply are equivalent to DIN 2093 standardized.
• Use the volts that have more than 10.9 for JIS strength class.
• Attach the spring washers without gap in the part of attachment ( "A" in fig.13 ).
If there is gap in the part of attachment, it is afraid that the torque arm is damaged.
• Check spring washers that are smashed. If the spring washers are attached with tightening of nuts such that they are smashed,
they are afraid that spring washers have no function for shock absorbing ,and that BUDDYBOX and the machine of the customer
are suffered too much force. In the case of using double nuts, be careful to tighten them without smashing of spring washers.
• For the wear reduction of the spring washers, apply any lubricant such as grease to faces of contacting each spring washers.
• Make always the bolts looseness prevention such as using adhesive for looseness or U-nuts.
• In the case that gap is arise on the part of attachment by initial sag of spring washers, adjust to turn gap to zero-gap with
secondary tightening of the nuts.
Then be careful not to smash the spring washers.
