SOME SYMBOLS MAY NOT BE AVAILABLE DUE TO THE CHAIR SETUP OR MODEL

MOUNTING HOLES MEASUREMENTS
A strong and level foundation is required to secure the
installation of the base.
It may occur during storage or transport the non-electrical telescope
column fastens in the lower position.
Adjust this easily by fastening the lockable arm for swing,
li up the release handle and pull up the chair.
MOUNTING ON A DECK RAIL
First, make sure to have mounted the deck rail according
to its user manual. The bolts for mounting the chair to the
deck rail is already in place in the carrier wagon.
If you have an electrical deck rail and the cabling of the
switch is done by quick-connections already implemented
in the chairs column.
CARE AND MAINTENANCE OF LEATHER
As a natural product, leather is very durable and hardwearing, but all leather products require cleaning
and protection. By following these instructions, you will ensure a long and lasting leather quality. Never
place leather furniture closer than 20-30 cm to a radiator or in direct sunlight.
CARE AND MAINTENANCE OF FABRIC
Regular light vacuuming. Occasional cleaning should be done with a reputable brand of upholstery
shampoo following the manufacturer’s instructions
LEATHER CLEANING
Cleaning removes everyday dirt and stains from
your leather. Without proper cleaning the leather
will over a period of time leave grease spots or dis-
coloration’s. To avoid this, clean with So Cleaner
on a regular basis. We advise once a month.
LEATHER PROTECTION
Protect your leather to guarantee that the origi-
nal quality of the leather will be maintained. Use
Leather Protection Cream, we advise 2-4 times a
year. This will protect against spots and preserve
the leathers soness.
MAINTENANCE OF MOVING PARTS
Glide parts of the chair can be lubricated with a silicone-based lubricant. If the chair is on a deck rail, it is
important that the deck rails railway is NOT lubricated.
